1 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
3 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
4 N_WARNING are the same except for the N_EXT bit, so just use their
5 values alone, rather than OR-ing them with N_EXT.
7 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
9 * mipsread.c (parse_lines): Deal with negative extended line
12 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
13 global symbol conflicts.
15 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
17 * .gdbinit: Move 'set complaints' to top, so it runs even in
18 case we aren't debugging GDB.
19 * language.c (_initialize_language): Fix type check and range
20 check documentation strings.
21 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
22 language.c can use it. (Though language.c should really not be
23 handling warnings/errors the way it does, FIXME.)
24 * symtab.c (lookup_primitive_type): const lint.
26 Bugfix from Peter Schauer:
27 * source.c (lines_to_list): Make signed, to avoid comparison
28 going unsigned and complaining that -3 is too high for 21 lines.
29 * stack.c (lines_to_list): Ditto.
31 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
33 * Makefile.in (HFILES): Add minimon.h.
34 (VERSION): Roll version number to 4.0.95.
35 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
36 New rules for building distributions. Normal distribution
37 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
38 one level up from here; it calls make-proto-gdb.dir to build a
39 directory `proto-gdb' which is an image of the release. The old
40 `gdb.tar.Z' rule still works too.
41 * config.sub, configure: Roll in latest from ..
43 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
45 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
46 new-target, and new-config chapters; fix minor typos; come closer
47 to usual GNU markup conventions for @file @samp @code @var.
49 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
52 * mipsread.c (parse_partial_symbols): Enter the name of all
53 structs/unions... into the psymtab so we can access them if the
54 symtab is not read in.
55 * mips-tdep.c: Remove some unneded (?) #includes.
56 * xconfig/dec3100: Add HAVE_STRSTR.
58 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
60 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
61 * c-exp.y, m2-exp.y: Lint.
62 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
63 * valprint.c (val_print_fields): Check for stub type.
64 * mipsread.c (_initialize_mipsread): Avoid using
65 builtin_type_void at initialize time.
66 (mipscoff_symfile_read): use it now.
68 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
70 Merge multiple-language support, and partial Modula-2 support,
73 * i387-tdep.c: New file, consolidates most 80387 support,
74 and eliminates host dependency on double<->extended conversions.
75 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
76 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
78 * symfile.c (allocate_symtab): New fn, consolidates the work
79 of allocating and initializing a new struct symtab. Set the
80 language of the symtab based on its filename extension.

82 * mipsread.c (new_symtab): Use it. Minor formatting changes.
83 * dbxread.c (end_symtab): Use it.

86 code for saving types of parameters with each function definition.
87 * dbxread.c (define_symbol, function and parameter cases): Ditto.
88 (read_dbx_symtab, case N_DEFD): Ignore.
89 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
90 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
91 #if 0 out its uses, though, since they set a dead value.
92 * coffread.c (end_symtab): Use allocate_symtab.
93 (process_coff_symbol): #if 0'd for functions and params as above.
94 (read_enum_type): Recognize Modula-2 BOOLEAN.
95 * symtab.c (add_param_to_type): #if 0'd function to add a
96 parameter type to a function type's field list.
98 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
99 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
100 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,

111 * m2-exp.y: New file with the Modula-2 parser and etc.
112 * expread.y, expread.tab.c: Remove.
113 * breakpoint.c, eval.c, printcmd.c, expression.h: Use
114 parse_expression and parse_exp_1 rather than parse_c_expression
117 * symtab.h (enum languages): Move to defs.h.
118 (enum type_code): Add TYPE_CODE_CHAR and TYPE_CODE_BOOL.
119 Declare Modula-2 builtin types.

149 declarations, and definitions.
153 * main.c (main): If error() is called during early
154 initialization, print its message and then exit(1) from GDB.
156 * valprint.c (type_print_base): Avoid printing garbage for ints
158 (_initialize_valprint): Warn about host/target size assumption;
159 improve long long support slightly.
161 * convex-tdep.c (comm_registers_info): Avoid parsing decimal and
162 hex -- let parse_and_eval_address do it.
164 * doc/gdbint.texinfo (Languages): Doc how to add a language.

168 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
170 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
171 entries are enclosed herein:
173 Mon Jun 3 17:05:45 EDT 1991
175 m2-exp.y Created. Tested outside of GDB for a few days. Proper
176 operators were added, C specific operators and tokens
177 removed. yylex() revamped to some extent. Still things
178 missing from the grammar, such as sets.
179 Tested for two weeks in GDB v3.5.
181 Tue Jun 11 17:23:48 EDT 1991
183 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
184 so they are built-in. Sort of a hack.
186 Fri Jun 14 12:53:51 EDT 1991
188 m2-exp.y Added range checking for numeric constants. Any numeric
189 constant is assumed to be of builtin type INTEGER unless:
190 (1) it is octal or hexadecimal, in which case it is a
191 CARDINAL; (2) it is too big to fit into an INTEGER, in
192 which case it is a CARDINAL.
193 eval.c Added simple range checking for +, -, and * on integers.
194 Doesn't work very well for *, since 6 * 1,000,000,000 =
195 1,705,032,704, which fails the simple test of result >=
196 first_operand, no matter in what order the operands are.
198 Tue Jun 18 14:11:30 EDT 1991
200 Broke the parser into parts, one containing the C grammar and the other
201 containing code to be shared by all of the grammars.
203 The following files no longer exist:
208 The following files were added:
210 c-exp.y (The C grammar)
211 m2-exp.y (The Modula-2 grammar)
212 parser-code.c (Code that is shared by the above grammar)
216 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
217 now necessary to use the Bison compiler compiler, since it
218 will generate function/variable prefixes other than yy.
220 Tue Jun 18 16:47:49 EDT 1991
222 symtab.[ch] Added the external variable working_lang, than holds the
223 value of the current working language.
224 Added the ennumerated type language_mode, with the values
225 language_auto and language_manual, the former meaning that
226 GDB sets working_lang as needed, and the latter meaning
227 that the value of working_lang is totally under user
229 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
230 REAL, BOOLEAN and CHAR. Also added the type codes
231 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
232 utils.c Added set_language_command and show_language_command to
233 implement the GDB support commands "set language" and
235 expression.h A number of identifiers were added to the type exp_opcode
236 to facilitate Modula-2 builtin functions, integer
237 division, and array indexing.
239 Wed Jun 19 13:25:58 EDT 1991
241 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
242 if the language specified by working_lang requires the use
243 of strict typing of expressions. Eventually, even this
244 will be able to be changed by the user.
245 Added the macro RANGE_CHECK, which evaluates to non-zero
246 if the language specified by working_lang requires the
247 checking of a value against the domain of its type.
248 Eventually, even this will be able to be changed by the
250 language.[ch] Predicates involving types (simple_type, ordered_type,
251 same_type, integral_type, numeric_type, character_type,
252 boolean_type, float_type) are added. These predicates are
253 based on the current value of working_lang, and are handy
256 Wed Jun 19 15:39:34 EDT 1991
258 eval.c Added the function type_array_rank which computes the rank
260 valarith.c Added the funtion value_bool, which when given a integer
261 value.h value (ie. struct value *) as an argument, it returns a
262 boolean value (ie. struct value *) true if that integer
263 is non-zero, and a boolean value false otherwise.
264 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
265 will print out properly.
267 Wed Jun 19 16:36:34 EDT 1991
269 valops.c Added the function value_capitalize, which returns it
270 value.h argument capitalized if its argument is a lowercase
271 letter, or the argument unchanged if its argument is not a
273 valarith.c Added the function range_check_p, which returns non-zero
274 value.h if its value argument is between the integral bounds upper
276 Added the function range_check_enum_p, which makes sure
277 that its value argument is a valid member of the domain of
279 Added the function range_check_range_p, which makes sure
280 its value argument lies between the upper and lower bounds
281 of its type argument, which must be a ranged type.
282 Added the function check_array_index, which range and type
283 checks an index of an array.
284 Added the function value_multi_subscript, which computes
285 array[idx1,idx2...idxN], given a value array and an array
286 of values representing indicies.
287 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
288 unpack_long to work with TYPE_CODE_BOOL and
291 Wed Jun 19 18:04:08 EDT 1991
293 symtab.c Stored pervasive types in a structure and make
294 lookup_pervasive_type() a lookup function that was based
295 on working_lang. If lookup_pervasive_type() returned
296 non-zero, then that value was returned (a fix, since
297 before it simply wouldn't return the pervasive type.)
298 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
299 non-zero if the language specified by working_lang means
300 "conversion" when it says "cast".
301 valops.c Added the function value_real_cast(), which performs a
302 value.h *cast*, not a *conversion*, which is what value_cast()
303 does when it can. In particular,
304 value_cast(<float_type>,4) = 4.0, while
305 value_real_cast(<float_type>,4) = some mess.
306 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
307 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
308 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
309 and MIN on integral types. *NOTE*: These are currently
310 hardcoded to work only if there are 8 bits per storage
312 eval.c Made logical functions call value_bool to return a
313 properly typed boolean value, based on working_lang.
315 Thu Jun 20 11:55:27 EDT 1991
317 valprint.c Types now print out in a Modula-2 fashion. This works for
318 the cases when the type is printed out step-by-step, that
319 is, it doesn't work when the name of a structured type
320 (which includes the keyword "struct", etc.) is simply
322 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
323 since type specifications in C and Modula-2 are very
324 different. The C printing of a type is very recursive,
325 whereas in Modula-2 it is generally very simple. C has
326 type prefixes and suffixes, which have no real analogue in
327 Modula-2. Maybe type_print() should call a language
328 specific type printer. This is also advantageous if we
329 compile GDB to exclude some of the languages. We'll just
330 leave those functions out.
332 Thu Jun 20 16:57:10 EDT 1991
334 dbxread.c When reading the complete symbol table in (via
335 psymtab_to_symtab()), the number and types of function
336 arguments are added to a function type. define_symbol()
337 calls add_param_to_type() to accomplish this.
338 Assumption: when we come across a function definition
339 (N_FUN symbol with an 'f' or 'F' in the name), its
340 arguments will appear before another function definition.
341 When a function is found, a pointer to its type is placed
342 in the global in_function_type. Changes that
343 add_param_to_type() makes are to this global.
344 valprint.c The type of a function now includes (for Modula-2) the
345 types of its parameters.
346 eval.c Type checking and a check for the proper number of
347 arguments is now done for function calls. Not sure of the
348 impact this has on C++ member function yet.
350 Thu Jun 20 19:58:48 EDT 1991
352 valprint.c Rewrote the type printer. Broke it into two language
353 specific parts, adding the functions type_print_m2() and
355 An unfortunate consequence is this: if you debugging a C
356 program in Modula-2 mode (why?), info types does not work
357 well with regular expressions, since the types are printed
358 out in Modula-2 terminology, but stored in C terminology.
359 language.[ch] Added the functions new_type_last(), type_keyword(), and
360 type_sep() to aid in the printing of typedefs.
361 symtab.c Made the printing of typedefs as language independent as
362 possible through calls to new_type_last(), type_keyword(),
365 Fri Jun 21 11:50:26 EDT 1991
367 dbxread.c Check all incoming ennumerated types. If it looks like
368 Modula-2's BOOLEAN type, then change the type_code of the
369 type to TYPE_CODE_BOOL so we can process it as a boolean
371 valprint.c Replaced some of the 0x%x with calls to sprintf and
372 hexformat() in val_print().
373 language.[ch] Added the function hex_to_string(), which converts its
374 integral argument to a hexadecimal number (format is
375 language based) and returns the result as a string.
377 Mon Jun 24 12:25:07 EDT 1991
379 valprint.c Some functions call type_print_1() directly, instead of
380 value.h using type_print(), so they can specify where (column) to
381 print things. Since type_print() takes care of language
382 dependence, that needs to be called first. Added a
383 parameter depth to type_print() (so it is now like
384 type_print_1). Changed type_print to type_print_at, and
385 made type_print a macro that passes a depth argument of
387 symmisc.c Changed all calls to type_print_1 to calls to
389 Makefile.dist Made it possible to build GDB for a specific set of
390 depend languages. Do this by passing a definition for the macro
391 LANGS to make. LANGS should be a string containing a
392 space-separated list of language names (ie. LANGS="c m2").
393 The default is to build all languages. Note that grammar
394 files must follow the naming convention of <lang>-exp.y.
395 gdb.lang This holds the current value of the LANGS macro. It is
396 examined every time make is called, and is updated if
398 eval.c Added #ifdef _LANG_<lang> to these files.
399 expread.c Still need to add them to dbxread.c and coffread.c.
407 Mon Jun 24 16:33:11 EDT 1991
409 language.[ch] Added the functions hexformat_pre() and
410 hex_to_string_pre(), which take a prefix argument to
411 include in the format string. Thus, hexformat_pre("08") will
412 return "0x08x" (if the working language is language_c).
413 Made hexformat() and hex_to_string() calls to the above
414 with "" as the prefix argument.
416 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
417 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
418 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
419 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
420 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
421 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
422 valprint.c, vax-pinsn.c
424 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
425 calls to hexformat() and hex_to_string(). Format strings without
426 the leading "0x" were ignored.
428 depend Updated to take the above into account.
431 Tue Jun 25 15:27:18 EDT 1991
433 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
434 and type_check_t to keep track of the current state of
435 range and type checking.
436 main.c Added the variables range_mode, range_check, type_mode,
437 and type_check to record the current state of range and
438 type checking. Added initialization code to main().
439 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
443 Tue Jun 25 17:57:08 EDT 1991
445 dbxread.c process_one_symbol() updates the variable (enum language)
446 source_lang based on the extension of the filename
447 contained in the N_SO sybmol that started this symtab.
448 When end_symtab() is called, the value of source_lang is
449 put into the language field.
450 stack.c select_frame() sets working_lang (and possibly type_check
451 and range_check) to the language field of the symtab
452 associated with the frame that is selected if working_mode
453 is language_auto. If working_mode is language_manual, a
454 warning is printed and working_lang is not set.
455 language.c Added the function set_type_range(), which sets the value of
456 type_check and range_check (if their modes call for
457 automatic setting) based on the current value of
458 working_lang. A non-zero argument will cause the current
459 settings to be output.
462 Wed Jun 26 14:51:40 EDT 1991
464 eval.c Added range checks on assignment.
465 m2-exp.y Added the grammar for sets to the language. Currently,
466 these do not do anything except print an error message.
468 Wed Jun 26 17:01:04 EDT 1991
470 m2-exp.y Added the ability for parse_number() to parse negative
471 numbers. A global flag is set upon encountering a unary
472 minus. This was done to make, for example, 1 parse as a
473 CARDINAL, and not as an integer, per Wirth's examples in
474 Programming in Modula-2 ed.4.
475 valprint.c Added support for "set radix 2" by then setting
476 output_format to 't'.
477 eval.c Implemented range checking on subrange types. Added calls
478 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
479 Implemented MIN and MAX for ennumerated types. The
480 minimum value of an ennumerated type is defined by Wirth
481 as the first identifier, and the maximum as the last.
482 m2-exp.y Made octal numbers ending with "B" be characters and those
483 ending with "C" be numbers, per Wirth's book. (p. 34)
485 Thu Jun 27 14:11:52 EDT 1991
487 stack.c select_frame() now only sets working_lang, it does not
488 notify the user. If working_mode is language_manual, then
489 a warning is issued once.
490 main.c At the end of each call to execute_command(), working_lang
491 is checked against the local static (enum language)
492 current. If they differ and working_mode is
493 language_auto, the new settings of language, type and
494 range checking are printed out.
495 stack.c Modified frame_info() to include the language of the
496 current frame in the output of "info frame".
497 language.[ch] Added the function language_str() which returns the name
498 of the current language.
500 Fri Jun 28 15:33:14 EDT 1991
502 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
503 the language. INCL and DECL currently cause an error,
504 since sets are not implemented yet. INC and DEC are
505 implemented as PREINCREMENT/PREDECREMENT with one
506 argument, and as ASSIGN_MODIFY with two arguments.
507 eval.c Added type checking to the above cases.
508 value.h Added not_lval_constant to the lval_type ennumerated type.
509 not_lval_constant means that the value is a constant
510 value; that is 3 or 'a' or TRUE, not as in a constant
511 identifier. This is used to help coerce numbers such as 3
512 to either signed or unsigned numbers.
513 valops.c Added the function value_coerce_constants() which coerces
514 constant integers as following: if one is a constant and
515 the other is not, the constant's type is set to the type
516 of the other argument. If both are constants and one is
517 signed, the other is converted to a signed constant.
519 Sat Jun 29 17:26:29 EDT 1991
521 valarith.c Added a better range checker. It now checks range
522 (successfully) on integral operations [+-] (signed and
523 unsigned) for any C sized type. Still does not work well
525 int_in_size() returns an integer that is coerced to fit into
526 specified number of bytes.
528 Mon Jul 1 13:04:14 EDT 1991
530 language.[ch] Added the function binop_result_type(), which returns the
531 builtin (struct type *) type that would be the result of a
532 binop on the two values V1 and V2.
534 Wed Jul 3 19:22:53 EDT 1991
536 source.c Extended source_info() to include the source language in
537 the output from "info source".
539 Fri Jul 5 13:48:52 EDT 1991
541 utils.c Moved the support functions for the GDB set/show commands
542 dealing with language into language.c.
543 language.c Added the function language_info(), which displays info
544 about the current working language, type and range check
545 settings. Called via the GDB command "info language".
546 Added an initialization routine _initialize_language(),
547 that sets defaults for the language, type and range
548 variables and sets up the new GDB commands.
549 main.c Language setup moved to language.c.
552 Mon Jul 8 10:10:22 EDT 1991
554 valarith.c Debugged the range checker for arithmetic. Still does not
555 work for multiplication very well.
557 Mon Jul 8 12:40:37 EDT 1991
559 language.[ch] Added the function value_true() which returns non-zero if
560 its argument represents a boolean true value.
561 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
562 check the truth of an expression.
564 Thu Jul 11 12:51:34 EDT 1991
566 language.[ch] Added the predicate structured_type(), which returns
567 non-zero if the argument is a structured type.
568 Added the predicate pointer_type(), which returns non-zero
569 if the argument is a pointer type.
570 eval.c Added the ability to do addition and substraction on
571 pointers and integers. This case simply bypasses the
574 Thu Jul 11 14:41:42 EDT 1991
577 Added the symbol N_DEFD (0x4a) which is a definition
578 module dependency that is used by the GNU Modula-2
579 compiler and the linker. It is not important to GDB,
580 except that [dbx|coff|mips]read.c should ignore these
583 Fri Jul 12 16:07:00 EDT 1991
585 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
586 0 in val_print(). Also added statements to the else part
587 to coerce type (argument to val_print) to a pointer type
588 if it is an "array of unspecified length".
589 valops.c Added the function value_m2_string(), which returns a
590 (value) value which is a constant string, whose type is
591 (ARRAY [0..n] OF CHAR). The length field of the type
592 structure is set to zero, so it will be interpreted as an
593 "array of unspecified length".
594 stack.c Moved the language/frame mismatch check to
595 main.c:execute_command().
596 main.c The working language is recorded each time
597 execute_command() is executed. If working lang has
598 changed during its execution, then the new
599 language/type/range info is printed out for the user. If
600 the working language does not match the language of the
601 frame, a warning is issued.
603 Sat Jul 13 16:16:39 EDT 1991
605 eval.c Moved all the type-checking stuff for operators to
606 language.[ch] language.c. This is so we can keep language-specific
607 stuff (like for what type operators are defined) in
609 language.[ch] Added the function binop_type_check(), which checks to see
610 if its two (value) arguments are type-compatible with its
611 opcode argument. The opcode should represent an operation
612 involving an operator. Also added the macro function
613 unop_type_check, which calls binop_type_check with a
614 NULL second argument.
615 expprint.c Added Modula-2 operators to the op_print_tab, so info
616 expression.h break works correctly. Also added "op_string", which
617 returns the string corresponding to the (enum exp_opcode)
618 opcode that is its argument.
621 Sat Jul 13 18:26:18 EDT 1991
623 coffread.c Added code to record the type of function arguments with
624 each paricular function. Code is very similar to that
626 dbxread.c Moved add_param_to_type() to symtab.c
627 symtab.[ch] Added function add_param_to_type() from dbxread.c
629 *** NOTE: The above additions have not been tested.
631 Mon Jul 15 12:50:47 EDT 1991
633 langauge.[ch] Added the functions type_error and range_error, which work
634 like error() except if the type/range mode is set to
635 *_mode_warn, then they do not do a return_to_top_level(),
636 but merely print a warning.
637 Also changed [set|show]_[type|range]_command() to support
638 the new "warn" feature.
640 Thu Jul 18 17:50:54 EDT 1991
642 mipsread.c Added code to record the type of function arguments with
643 each particular function. Code is very similar to that
646 *** NOTE: The above additions have not been tested.
648 Fri Jul 19 11:19:10 EDT 1991
650 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
651 UMIN_OF_SIZE, which when given a size of a numeric type,
652 return the maximum and minimum value it can hold. UMAX...
653 and UMIN... return the result for unsigned types.
654 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
655 struct types. They call above macros.
656 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
657 avoid a name conlict with the above.
658 c-exp.y Added range checking on numeric constants in
659 parse_number() for completeness.
660 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
661 return 0 if working_lang is not language_c.
663 Thu Aug 8 14:17:22 EDT 1991
667 breakpoint.c Documentation strings of some commands changed to
668 eliminate the references to the C language where
671 Tue Aug 13 15:48:03 EDT 1991
673 m2-exp.y Added qualified identifiers to the grammar. The semantics
674 are slightly different from those of the GDB operator ::
676 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
677 type_exp, where type_exp is any valid type expression.
679 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
680 printcmd.c Modified ptype_command() so it actually parses the input
681 (necessary for type expressions with scope qualifiers).
682 Added the function ptype_eval() which expects an
683 expression composed of one OP_TYPE element.
684 *.[ch] Replaced all occurences of parse_c_expression with
686 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
688 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
690 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
692 Small fixes from Peter Schauer:
694 * infrun.c (child_attach): Lint.
695 * solib.c (find_solib): Handle shared libs version 2.
697 Small fixes from David Wood:
699 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
703 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
706 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
707 chars_per_line is at maximum (user typed `set width 0'). Fix
710 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
712 * coredep.c: include ptrace.h where necessary.
713 * mipsread.c(parse_lines): fix unsigned char problem that was
714 messing up line numbers on SGI's and possibly other MIPS based
716 * infrun.c (child_create_inferior): use better test to check
717 return val from setpgrp().
718 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
719 for sgi/irix support.
721 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
723 * mipsread.c (parse_symbol): Put non-static procedures
726 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
728 Patch together `text_start' and `text_end' for 29K port.
730 * exec.c (exec_command): If NEED_TEXT_START_END, define the
731 variables and set them based on the exec file.
732 * am29k-tdep.c: declare text_start.
733 * valops.c (call_function_by_hand): declare text_end.
735 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
736 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
737 because machines that do this will also have to know to
738 set NEED_TEXT_START_END. Besides, it was a redundant way to
740 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
741 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
744 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
748 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
749 Pass MUNCH_DEFINE to munch whenever we run it.
750 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
751 format string; use 0x%x instead.
752 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
753 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
754 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
755 * inflow.c: Handle `short' process group IDs.
756 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
757 and check for ptrace errors.
758 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
759 (coff_symfile_init): Initialize text_bfd_scnum.
760 (read_coff_symtab): Use it to find the text [and absolute?] sections.
761 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
762 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
763 Merge target arm case with other "easy" cases. Add target
764 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
765 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
767 * minimon.h, remote-adapt.c, remote-mm.c: Add.
768 * munch: Cope with RT/PC putting fns in data segment.
769 Restore ability to override `nm' by specifying MUNCH_NM.
770 * xconfig/rtbsd, xconfig/ultra3: New host systems.
771 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
772 and remote-adapt. Remove encapsulated coff #define's (the
773 support should go in BFD, and gdb shouldn't know or care).
774 * tconfig/a29k-kern: Same, but for remote kernel debugging.
775 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
776 * tm-29k.h: Update BADMAG (though it should go away).
777 Allow the register definitions to be overridden in another
778 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
779 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
780 DUMMY_SAVE_GR96, for handling kernel calling conventions
781 that use GR64+ rather than GR96+.
782 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
783 remote debugging of Ultra3 kernel. Includes tm-29k.h and
784 overrides various things.
786 * remote-mm.c (mm_attach, mm_wait): Handle attach like
787 child_attach does, making a clean stop in the newly attached
791 * coffread.c: Make coffread independent of any particular
792 variant of COFF. Avoid #include-ing any particular one except
793 internalcoff.h. BFD now passes key values for symbol reading
794 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
795 and the symbol masks and shifts); use them.
796 Remove obsolete end_of_text_addr.
798 * exec.c: Remove unused include files.
800 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
802 * Makefile.in (documentation targets): Pass $(M4).
805 * stack.c (down_silently_command): Check for stack existence.

811 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
813 * core.c (core_file_command): Print frame at coredump with
814 its level number, by calling print_stack_frame.
815 * frame.h: Add selected_frame_level, print_stack_frame.
816 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
817 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
818 Change print_sel_frame and print_selected_frame callers to
821 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
822 * symfile.c (free_named_symtabs): Ditto.
823 * main.c (main): wrap_here needs an arg.
824 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
825 (solib_add): Avoid noise.
826 (solib_create_inferior_hook): Lint.
827 (sharedlibrary_command): Move dont_repeat to here.
828 * utils.c (error): Call wrap_here to force buffered output.
830 Small patches from Peter Schauer:
832 * coffread.c (start_symtab): Free any existing line_vector before
834 (read_coff_symtab): Ditto for type_vector.
836 * source.c (lines_to_list): New variable, replacing function.
837 (all uses): Use as variable.
838 (_initialize_source): Add 'set listsize' and 'show listsize'.
839 * utils.c (lines_to_list): Remove function.
840 * stack.c (print_frame_info): Use as variable.
841 * defs.h (lines_to_list): Remove declaration.
843 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
845 * breakpoint.c (insert_breakpoints): Restore warning about
846 the program might be running in another process, but only for
847 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
848 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
850 * utils.c (error): if error_pre_print is set, print the string
852 * main.c (main, print_gnu_advertisement, print_gdb_version):
853 Reformat legalese so it always prints, but acts as an "I'm here"
854 message while symbols are being read. If any errors occur,
855 print a few newlines to set off the message and start it at the
856 left margin. Remove mention of "help" command, and don't yak
857 about symbol reading.
858 (catch_errors): Error string is now printed first in case of
860 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
861 suggest the "help" command.
863 * Makefile.in (VERSION): Set to 4.0.2.
865 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
867 * .gdbinit: Remove useless "rr" command. Set complaints
868 to 1 for people debugging gdb.
870 * breakpoint.c, remote-vx.c: Reword strings printed by
871 catch_errors callers.
873 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
875 * WHATS.NEW: "history write -> history save". Doc "write on/off".
878 Fix some infrastructure to be able to cope with host and target
879 machines with different sized basic types (ints, ptrs, etc).
882 * values.c (value_from_longest): Rename from value_from_long.
883 Handle pointer types as well as integers, so that targets with
884 different pointer sizes from the host can be accomodated.
885 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
886 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
887 uses of value_from_long to value_from_longest.
888 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
889 the correct pointer type to value_from_long{est}.
891 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
893 * remote-vx.c: Remove obsolete code for calling functions via
894 vxworks kludge interface (it referenced value_from_long).
896 * valops.c (value_string): Find malloc with lookup_misc_func, not
899 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
901 Make writing to files work properly. (Fixes to BFD are also needed.)
903 * core.c (core_open): Open file ourselves, read or r/w, depending on
904 write_files. Use bfd_fdopenr.
905 * gdbcore.h (write_files): New variable.
906 * exec.c (write_files): Define variable, add set&show for it.
907 (exec_file_command): Use write_files to open for read or r/write.
909 Make shared library reading happen automatically. These changes
912 * inferior.h (stop_soon_quietly): Add to exported variables.
913 * infrun.c (child_create_inferior): call solib hook, if defined.
914 (child_attach): call solib hook, if defined.
915 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
916 (find_solib): Use lookup_misc_func rather than hand-rolled.
917 (symbol_add_stub): New stub for catch_errors.
918 (solib_add): Avoid output if !from_tty. Catch errors rather
919 than just calling symbol_file_add and bombing.
920 (solib_create_inferior_hook): Interface with the target process
921 to let it read and alloc shared libs, then figure out what it did.
923 * core.c (validate_files): Fix typo, soften warning.
926 * utils.c (fputs_demangled): Avoid duplicate printing if
929 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
932 * main.c (catch_errors): Change argument to a char * from an int,
933 since a char * can point to a struct full of glop, but an int
934 is not guaranteed to be able to hold a pointer.
935 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
936 breakpoint_re_set_one, breakpoint_re_set): Adapt.
937 * core.c (core_open, solib_add_stub): Adapt.
938 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
940 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
942 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
943 by adding .NOEXPORT target.
945 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
949 * Makefile.in (VERSION): Roll to 4.0.
950 (gdb.tar.Z): Make refcard.ps as well, for shipment.
952 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
954 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
957 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
960 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
962 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
963 reflect above name change
965 * WHATS.NEW: correct pointer to refcard.
967 * doc/gdb.texinfo: update New Features, Installing
969 * doc/gdbint.texinfo: add short description of configure +template
971 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
973 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
975 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
977 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
978 tar file, add dependencies for referenced doc files.
980 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
982 * coffread.c, symfile.c, stack.c: saberized.
984 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
986 * doc/refcard.tex: permuted Essential Commands sec
988 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
990 set/show symbol-reloading
991 default set complaints 0
993 RET-repeat disabled after prompted long displays
994 processID (attach) interpretation of 2nd GDB cmdline arg
996 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
998 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
999 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1000 breakpoint.c, main.c: lint.
1002 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1004 Install new configuration scheme for GDB and friends.
1006 * config.sub: Translate ordinary names to three-part names.
1007 * configure: Use three-part names internally.
1008 * configure.in: Translate three-part names to filenames.
1010 * README, WHATS.NEW: Update for gdb-4.0.
1011 * Makefile.in: Roll VERSION to 3.99.
1013 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1015 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1016 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1017 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1018 to single structures rather than arrays; when passing
1019 their address, use &. This avoids trouble with bdead compilers.
1020 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1021 instead. This avoids portability headaches.
1022 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1024 * source.c (open_source_file): Avoid ANSI const bdeath by
1025 skipping declaration and then casting result value.
1026 * tm-hp300bsd.h: Clarify comment.
1027 * utils.c (strstr): Result is const char *; ANSI bdeath.
1028 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1029 since system include file defines it differently from "defs.h",
1030 though the two are equivalent for our purposes.
1031 * tconfig/hp300bsd: Add m68k-tdep.o.
1033 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1035 * tconfig/sun*4: Remove warnings about system assembler.
1037 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1039 * mcheck.c: Avoid warning about undeclared abort fn.
1040 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1041 it causes recursive calls to error() when used in cleanups.
1042 To do so requires that we make it a function, so we do.
1043 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1044 * utils.c (do_cleanups): Remove the current cleanup from the
1045 chain *before* calling it, in case error() is called from it.
1046 The result won't be pretty, but won't be an infinite loop either.
1048 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1050 * dbxread.c (read_struct_type): Grok anon structs for C++.
1051 (vb_name, vptr_name): Null terminate these strings.
1053 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1055 Minor bug fixes from BSD Net2 gdb:
1057 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1058 returns 0, there is no previous frame.
1059 * breakpoint.c (commands_command): If !from_tty, don't call
1060 input_from_terminal_p().
1061 * dbxread.c (record_misc_function): Speed up slightly.
1062 (compare_psymbols): Ditto.
1063 * infcmd.c (do_registers_info): Take a second argument to
1064 determine whether to print float registers. "info registers"
1065 does not do so anymore. "info all-registers" does, now.
1066 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1068 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1069 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1073 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1074 executing_breakpoint_commands if we are interrupted by error.
1075 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1077 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1078 catch_errors() so we can setup the frame regardless of whether
1079 the shared libs work.
1080 * ieee-float.c (double_to_ieee_extended): Get exponent from
1081 right place in little-endian systems. From John Carey.
1083 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1085 * main.c: Remove unused terminating_signals and catch_termination().
1086 (long_options): Terminate with a zero element.
1088 (gdb_readline): Make call-compatible with readline.
1089 (init_signals): Improve comments re vfork vs. signal.
1091 * utils.c (prompt_for_continue): Use new gdb_readline().
1092 If we prompt for continuation, we don't let CR repeat the previous
1093 command, once we get back to a prompt. It's too easy to keep
1094 hitting CR, expecting "--more--" prompts, and have some long
1095 command start repeating on you.
1097 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1099 * blockframe.c (frameless_look_for_prologue): Speed up by
1100 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1101 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1102 Define two variants, one faster.
1103 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1104 and return zero, rather than giving an error.
1105 (setup_arbitrary_frame): Initialize the PC in the new frame.
1106 (skip_prologue): Add a second arg saying whether we're just
1107 checking for a frameless function or not.
1109 * core.c (core_open, core_close, core_xfer_memory): Move
1110 section table pointers and bfd* into the target_ops.
1111 (core_open): Allow errors in shared lib reading, etc.
1112 (core_files_info): Describe shared library sections.
1114 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1115 exec_files_info, set_section_command): Move section table
1116 pointers and bfd* into the target_ops.
1117 (add_to_section_table): Add BFD to section table.
1119 * target.c (target_xfer_memory, target_info): Pass target to
1120 xfer_memory and target_info functions.
1123 * gdbcore.h: Move struct section_table.
1124 * target.h: New home of struct section_table.
1126 * solib.c (solib_add): New argument is the target_ops whose
1127 section list is to be added to, if any. Reallocate the
1128 sections in that target to add any that come from shared libs.
1129 (throughout) so_sections renamed to sections.
1130 (solib_xfer_memory): Deleted.
1131 * tm-sunos.h (SOLIB_ADD): Add target argument.
1132 (SOLIB_XFER_MEMORY): Delete.
1134 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1135 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1136 from target_ops. It's the same on all targets. Add two section
1137 pointers to target_ops.
1139 * stack.c (find_relative_frame): Dump ancient algorithm for
1140 "down", just use handy "next" pointers.
1141 (frame_command): Don't error if there is no stack; let user
1144 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1145 modifies static state in the parent process; new_tty itself
1146 runs in the child and modifies the child's file descriptors
1147 to match the saved static state.
1148 * infrun.c (child_create_inferior): Call new_tty_prefork,
1151 * infptrace.c (child_xfer_memory): Add ignored target arg.
1152 * remote-eb.c (eb_xfer_inferior_memory): ''
1153 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1154 * remote-vx.c (vx_xfer_memory): ''
1155 * remote.c (remote_xfer_memory): ''. Rename from
1156 remote_xfer_inferior_memory.
1158 * main.c (main): Only try to attach "corefile" argument if
1159 it starts with a digit.
1161 * symfile.c (symbol_reloading): New "set/show" variable.
1162 (symbol_file_add): Shorten message about symbol reading.
1163 (add_symbol_file_command): Merge with add_syms_addr_command,
1164 since this should work on all targets now.
1165 (stop_whining): Default to zero, to shut up complaints
1166 about bad symbol tables on many systems.
1167 (free_named_symtabs): Just exit unless symbol_reloading.
1169 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1170 and add comment explaining shared library screw.
1172 * source.c: #if defined => #ifdef.
1174 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1176 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1178 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1180 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1181 (doc/Makefile knows how to make one for local config)
1183 * Makefile.in: use doc/Makefile for doc targets
1185 * doc/Makefile: GDB documentation now has its own Makefile
1186 doc/refcard.tex: renamed from "gdbrc.tex"
1187 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1188 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1191 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1193 * values.c (baseclass_addr): When reading target memory, use the
1194 length of the basetype, not the upper type. We've only malloc'd
1195 enough space for the basetype, leading to errors in free().
1197 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1198 ends up as a function specially, since we know the actual type of
1199 the pointed-to address. This (somewhat) fixes display of
1200 expressions that include misc_function_vector names. Try `cond 1
1201 !strcmp("a","b")' then `i b'.
1203 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1204 The child can be proceeded from inside wait_for_inferior in
1205 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1206 getting skipped in that case.
1208 * expprint.c (print_subexp): Use filtered output, since the
1209 subroutines we call use it, otherwise the output is horribly
1210 mangled, since output of wrappable stuff comes out late.
1212 * Makefile.in: Bump VERSION to 3.98.1
1214 * infrun.c (child_create_process): Use execlp to find the
1215 shell to exec our target program. This requires some fiddling
1216 with `environ' since there is no execlpe().
1218 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1220 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1221 Minor rearrangement of refcard permits two new make targets--
1222 gdbrc.dvi DVI output for refcard, using CM fonts
1223 gdbrc.ps PostScript refcard, using PS fonts
1225 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1229 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1230 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1232 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1234 * doc/gdb.texinfo: last changes for release.
1235 Minor typo and formatting fixes; incorporated most fixes remaining from
1236 filed mail commenting on earlier drafts.
1238 Added warnings: pipes don't work in run command;
1239 conditions are converse of assertions;
1240 step over fn without debug info goes to next fn;
1241 vars may have "wrong" values near fn entrance, exit
1243 Added example from Kingston on printing repeated nonadjacent values
1245 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1246 shell mode for signals
1248 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1249 doesn't sound so much like its parent "Stopping and Continuing"; also
1250 moved entries on continue to top of section, so they don't get lost.
1252 Improved installation directions in appendix, added manual formatting
1255 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1257 * configure.in: Remove xm.h and tm.h even if we aren't linking
1258 new ones, so "./configure sun4; ./configure none" does the right
1259 thing. Assume that alldeps.mak and depend are already built in
1260 srcdir, and avoid running "make" (particularly "make depend",
1261 which involves "gcc") from inside configure. Build Makefile
1262 directly rather than building Makefile.conf first.
1263 * configure: Regenerate with above changes.
1264 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1265 to 3.98. Revise gdb.tar.Z procedure to produce a file
1266 called gdb-$(VERSION).tar.Z but which unpacks into a
1267 directory called "gdb". Move non-source files out of
1268 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1269 (depend): Don't try to do "gcc expread.y".
1270 (expread.o): Update dependencies by hand.
1272 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1275 Fixed a variety of small typos that prevented info from formatting
1276 cleanly; altered too-long heading for GPL Appendix, as discussed
1277 w/RMS; Changed date on cover to July 91.
1279 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1282 (1) Applied some fixes due to comments from Larry Breed (easier ones
1283 through chapsec 5.2)
1284 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1285 it's broken in latest texinfo
1286 (3) Introduced *some* use of [] for optional arguments, where
1287 explanation is not simpler by listing cmd w arg and cmd w/out arg
1288 separately. Still not using @deffn.
1289 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1290 couple of headings are too long. Need patches to texinfo or revision
1293 * Partial update to README (which still needs work for this
1294 release!): (1) use of configure corrected for new script,
1295 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1297 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1299 * symtab.c (lookup_symbol): Don't complain right off about
1300 no debug symbols; use the misc function vector first.
1301 (list_symbols): Use misc function vector to find symbols
1302 that don't have debug info, and print them.
1303 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1304 PC range doesn't match symtab PC range, as it does on the
1305 MIPS because our symtab reading isn't perfect.
1307 * dbxread.c (dbx_symfile_read): Make warning about
1308 "no debug symbols" slightly nicer.
1310 * source.c (select_source_symtab): If "main" symbol exists,
1311 but decode_line_spec can't find line info, don't just return
1312 a zero; try other source symtabs or give an error.
1314 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1315 their low addresses first, then rip through fixing high addrs.
1317 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1319 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1321 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1323 * Minor, mostly mechanical, cleanup of doc subdir for clean
1324 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1325 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1327 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1329 Mostly MIPS and general symbol-reading fixups.
1331 * doc/gdbint.texinfo: Add documentation on symbol-reading
1334 * mipsread.c: Remove kludges around #include "ecoff.h".
1335 Remove redefinitions of a_magic, etc, no longer used.
1336 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1337 Fix global overview comments to match symfile.c protocol.
1338 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1339 (mipscoff_symfile_read): Eliminate unused code. Avoid
1340 sorting all the symtabs, when all we have read here is psymtabs.
1341 The symtabs are sorted as they are created anyway. Tell
1342 condense_misc_bunches whether we're mainline.
1343 (psymtab_to_symtab_1): Pass filename when recursing, to make
1344 stack trace more informative.
1345 (parse_partial_symbols): Assume cur_hdr as argument.
1346 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1347 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1348 the TYPE_NAME of char *, since that's done in symfile.c.
1349 (free_numargs, parse_symbol, add_symbol, add_block,
1350 shrink_linetable): Declare these fns void.
1351 (upgrade_type): Convert tree of if's to switch. Clean up
1352 bogus "off == 0" handling with a complaint. Avoid setting
1353 field bitpos and bitsize of array with lower and upper bounds.
1354 Check specified bitsize of elements against their actual type's
1355 bitsize, and complain if different. Complain about unknown
1357 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1358 (psymtab_to_symtab_1): Print names of subsidiary files that
1359 are being read in. FIXME, we read far too many files. This code
1360 is not the problem, the problem is in parse_fdr where the psymtabs
1362 (cross_ref): Result should indicate that we used one aux entry
1363 normally, or two if we encountered a "next" entry. This used
1364 to leave the caller pointing at the wrong aux entry.
1365 (add_symbol): If overflowed cur_block, reallocate it larger,
1366 chase all pointers to it, and complain(), rather than clobber memory.
1367 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1368 (new_field): Only allocate one field initially, not two.
1369 Pull ++ out of macro argument. Simplify.
1370 (_initialize_mipsread): Avoid initialization of importd
1371 global_psymbols and static_psymbols.
1373 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1374 to properly set pst->symtab; avoid searching for it.
1375 (symfile_fns): Improve comments, add a FIXME.
1376 * dbxread.c: Update comments to reflect symfile protocol.
1377 (read_ofile_symtab, end_symtab): Return the symtab.
1378 (psymtab_to_symtab_1): Set pst->symtab.
1380 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1381 whether we're mainline.
1383 * symfile.h (sym_fns): Remove unused sym_discard member.
1384 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1386 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1387 the environment variable is not.
1388 * infcmd.c (finish_command): Use filtered printfs.
1389 * cplus-dem.c: Add struct tags to a few unnamed structs.
1390 * valops.c (value_coerce_array): Improve comments.
1391 * valprint.c (type_print_varspec_suffix): Print array size only
1392 if greater than zero.
1393 * m88k-tdep.c: Shift some lines left by one space, that had
1394 apparently been trashed at some point.
1395 * TODO: More things to do, a few got done.
1397 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1399 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1400 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1402 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1403 * expread.y, findvar.c, symmisc.c: Ditto.
1404 * printcmd.c (address_info): Update printed forms of LOC_
1405 symbols. Elim LOC_EXTERNAL.
1406 (print_frame_args): Keep track of param stack offsets before
1407 re-looking up to find the local register param is kept in.
1409 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1410 Further integration of mipsread into gdb. Eliminate unused
1411 routines, duplicate declarations. Handle static symbols in
1412 psymtabs as well as external symbols. When reading symtabs,
1413 insert symbols into the correct block (global, static, or a local
1415 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1417 (mipscoff_symfile_read): Don't call select_source_symtab.
1418 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1419 rather than SYMBOL_VALUE.
1420 (parse_external): Comment clobbering of top_stack.
1421 (parse_partial_symbols): Update comments. Allocate and parse
1422 static symbols as well as external symbols. FIXME, enum values
1423 are not handled in this pass, but should be. Inline new_psymbol.
1424 Use SYMBOL_VALUE_ADDRESS.
1425 (psymtab_to_symtab_1): Read symbols into global static block
1426 by default (until enter some function's local block context).
1427 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1428 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1430 * source.c (select_source_symtab): Select a source symtab
1431 from either the symtabs or, failing that, the psymtabs.
1432 (list_command): Update error message.
1433 (forward_search_command, reverse_search_command): Use getc, not
1434 fgetc, for speed. FIXME, add comment about buffers that die if
1435 overrun by long line.
1437 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1438 by an entire word, which is not portable, if we have a 32-bit
1439 field. (Code in dbxread.c already turns such bitfields, if
1440 aligned, into ordinary ints, but fixing this will help for other
1441 symbol formats and for future changes.)
1442 * core.c (core_open): Handle ANSI const brain death.
1443 * utils.c (vprintf): Fix varargs typo.
1445 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1447 * findvar.c (find_var_value): Handle &function better.
1448 * TODO: Document work needed on &fn and &array.
1449 * printcmd.c (print_address_symbolic): New arg is the prefix
1450 to print if a name is printed.
1451 (print_address_demangle): Honor "set print address" now.
1452 Use new arg above to improve spacing of output.
1453 * valprint.c (val_print): When printing function pointers,
1454 print symbolic form too.
1455 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1457 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1459 * core.c (memory_error): Reword error msg to mislead less.
1461 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1463 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1464 parse_partial_symbols): Use newer BFD internals (external_filehdr
1465 and external_aouthdr), byte-swap the fields that we care about
1466 before using them, and make the file header data local to
1467 read_the_mips_symtab rather than global.
1469 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1471 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1474 * main.c (command_line_input): Flush stdout and stderr
1475 before every call to readline. This reportedly fixes a bug
1476 that comes up in Sys V running emacs-gdb and/or xxgdb,
1477 when stdin/out are pipes or sockets.
1479 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1481 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1482 Avoid declaring Makefile dependencies, because GNU Make stupidly
1483 tries to update it if we do.
1485 * coffread.c: Revise for minor changes to bfd internal coff
1488 * configure: If -template= is given a relative path, make it
1489 absolute before recurring in subdirectories.
1491 * configure, configure.in, Makefile.in: Install "configure" script
1492 as replacement for config.gdb.
1493 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1494 * README: Update for configure, mostly. FIXME.
1496 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1497 target config files that they are for the host. When the lines
1498 get copied into the Makefile, this makes it more obvious what's
1501 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1503 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1504 tabs, which end up in the disassembler output inadvertently.
1506 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1508 Make it compile cleanly in an ANSI GCC2 environment.
1510 * blockframe.c: <stdio.h>
1511 * cplus-dem.c: free takes a void *, ifdef __STDC__
1512 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1514 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1515 * stddef.h, stdlib.h: Remove these files.
1516 * symtab.c: Avoid declaring qsort, close.
1517 * symfile.c: Avoid declaring close.
1518 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1519 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1521 Assorted other changes.
1522 * dbxread.c: include "libaout.h", not "liba.out.h".
1523 * printcmd.c (print_frame_args): Set recurse properly for
1524 indentation of struct and array parameters.
1525 * valops.c (value_cast): Allow cast to void.
1526 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1527 single_step() in a target-independent fashion.
1528 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1529 set up to be ready to continue. This makes us target independent.
1530 * infptrace.c (child_resume): Remove call to single_step; now
1531 can single step a SPARC target of any kind.
1533 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1535 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1536 docn into separate sections---basically chapters, plus two loose
1537 pieces that can be configured to go in different places. This
1538 allows GNU m4 to preprocess the manual without coredumping.
1540 * Makefile.dist: tell TeX where to find texinfo.
1542 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1544 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1545 the new target "rdl-apps.texinfo" which captures the Makefile
1546 variable that records where to find the Readline libraries.
1548 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1550 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1551 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1552 * defs.h (const, volatile): Only define if not already defined.
1553 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1555 * README: Update for release 3.95.
1556 * config.gdb: Don't create readline dir in subdir builds.
1557 * main.c: Include with "..." form for non-system include files,
1558 so "gcc -MM" for "make depend" works.
1559 Include readline files with "...h" rather than <readline/...h>.
1560 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1562 * coffread.c: Undo minor damage done by Rich Pixley. Use
1563 different internal and external representations of COFF
1564 data structures. Use new BFD routines for swapping them in and
1566 * symfile.c (free_named_symtabs): Avoid freeing file names that
1567 are null or empty. Old i960 tools seem to produce files that
1568 claim to have empty names, causing each successive file read
1569 to blow away the previous one.
1570 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1571 Move deferred_stores to top of file, but don't separate its
1572 #define's from its variable. Add commentary.
1573 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1574 favor of keeping the (working) config.gdb. Move readline
1577 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1579 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1581 * infptrace.c (fetch_registers): no result, since now void.
1582 * tconfig/news: target depends on m68k-tdep too.
1584 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1586 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1589 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1590 applied various small fixes due to or inspired by RMS comments
1592 * doc/gdb.texinfo: finished using all RMS comments, save those for
1593 appendices on readline and cmd history (which are in other source
1596 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1598 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1599 chapter 9; (2) documented 'break' command's menu mode for
1600 overloaded names, in response to hgs problem report C++ p-31
1602 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1604 * doc/gdb.texinfo: (1) better introductory example; (2) more
1605 consistent use of @code, @samp, @file, @kbd throughout; small
1606 cleanups to first three nodes; (3) new "Contributors" node;
1607 (4) Appendix, Renamed Commands; (5) divert specialized startup
1608 instructions to "Targets" chapter for generic manuals, while
1609 leaving them up front for manuals specific to specialized
1610 environments; (6) apply fixes from RMS comments through chapter 4.
1612 * pretex.m4: modify explanatory text slightly (and redefine
1613 "regexp") to keep GNU m4 from complaining. (It still crashes
1614 later, but one step at a time...)
1616 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1618 * readline/readline.c (update_line): Avoid dereferencing a pointer
1619 before comparing it to its bounds. Saber caught this.
1620 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1621 and only set PC if tgetstr returned non-null. Saber caught this.
1623 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1625 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1626 stuff for config manual) here where it counts; updated
1627 to use new subdir structure (gdb/doc/).
1629 * Makefile: generated from above via
1633 * gdbint.texinfo: added instructions on generating gdb.info* files
1634 locally for release. These are ordinary info
1635 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1636 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1637 to generate these, so we distribute them already formatted.
1639 * gdb.texinfo: included full Info node and menu crud (as generated
1640 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1642 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1643 put in comments-for-future gdb.info target (one day makeinfo will
1646 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1648 * gdb.texinfo: Updated to include new or old undocumented
1649 commands, at least the following (perhaps some others I forgot to
1650 record): info f, info float, info path, info program, info s, info
1651 set, info source, info terminal, info types, info user, set/show
1653 Also covered all recent GDB command renames for v4.
1655 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1657 * mipsread.c: Rather than keeping count of how many symtabs
1658 and psymtabs we have, for sorting purposes, count them when
1659 we need to sort. This fixes bug in rereading of symbol tables.
1661 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1663 * infcmd.c: renamed "info path" to "show paths"

1678 symtab.h, target.c, target.h: Lint.
1679 * core.c: setup and select frame after reading shared libs,
1680 else reading shared libs will clobber them. Lint.
1681 * utils.c (error): Force out any buffered wrap text.
1683 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1685 * remote.c: Remove decls of memory_insert_breakpoint
1686 and memory_remove_breakpoint, no longer used. (Suggestion of
1689 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1690 to make it easier to interface to "configure"'d libraries.
1692 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1694 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1695 aliases for set/show print.

1987 the symtabs which we all know and love: (1) Look in the
1988 STATIC_BLOCK for mangled symbols right after we check the blocks,
1989 (2, 3) Look in the STATIC_BLOCK for all the symtabs and psymtabs
1992 * main.c (cd_command): Call dont_repeat.

2207 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2208 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2238 command is add-symbols.
2239 * target.c (dummy_target): Permit add_syms_addr_command.
2241 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2243 Permit symbols to be superseded when new symbol files have
2244 been read in, particularly for VxWorks.
2246 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2247 to the main file, as well as to include files. Also, put global
2248 functions into the global psymtab, to make "i fun" work.
2249 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2250 new psymtab for it has been read.
2251 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2252 a file, once a new symtab has been read for it.
2253 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2254 looks harder to determine the top-level block before it's been
2255 queued to the psymtab list.
2257 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2258 If we have wiped out any old symbol tables, clean up at end of
2260 (symbol_file_command): Don't reference symfile_fns if it's zero.
2262 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2263 defines for the blocks of a blockvector that contain global and
2264 file-static symbols and the first of the smaller scope contours.
2265 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2266 decode_line_1, make_symbol_completion_list): Use the above.
2267 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2268 * dbxread.c (end_symtab): Ditto.
2269 * expread.y (block): Ditto.
2270 * mipsread.c (throughout): Ditto.
2271 * symmisc.c (free_named_symtabs): Ditto.
2273 * symtab.c (list_symbols): Process the first symbol of the
2274 static psymbols list.
2275 (types_info): Restore this function from its untimely #if 0.
2276 It's not perfect, but it is better than nothing.
2277 (_initialize_symtab): Restore "info types".
2279 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2281 * m68k-stub.c: Remote stub for 680x0's, created from
2282 rem-m68k.shar (which is removed).
2283 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2284 Remove RCS log stuff now that we use CVS and it blows our diffs.
2286 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2288 * symmisc.c (free_named_symtab): Make it work, in its current
2289 kludgy fashion. Change result to indicate if we blew away bkpts.
2290 * dbxread.c (end_symtab): Accumulate result from
2291 free_named_symtab and print warning if we blew user's state.
2292 * symfile.h: free_named_symtab now returns an int.
2294 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2296 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2297 is the first symbol read, even if not mainline.
2298 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2299 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2300 (set_section_command): New command ("section xxx yyy" -- should
2301 be renamed to "set section xxx yyy" FIXME) which sets the
2302 base address of a section of the exec file, overriding the
2303 virtual address that BFD reports.
2305 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2307 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2308 load symbols at any address while examining an exec file.
2310 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2312 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2313 for printing the float info is host-dependent, not
2314 target-dependent. FIXME.
2315 * i386-pinsn.c: Move #includes to top, remove useless ones.
2316 * i386-tdep.c: Don't bother including <.../reg.h> since we
2317 don't use it (and it doesn't exist on host systems).
2319 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2320 Convert negative numbers properly.
2321 (ieee_test): Make numbers really random; fix format arg.
2323 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2324 * core.c (core_detach): Unpush core_ops, which might not be on
2325 top. We used to just pop the top, which broke things. Don't
2326 need dont_repeat() any more.
2327 (core_file_command): Psst! Don't repeat it.
2328 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2329 * expprint.c (print_subexp): Avoid switch fallthru on
2330 BINOP_ASSIGN_MODIFY, so we can print += and such.
2331 * frame.h: Fix typo.
2332 * inflow.c (kill_command): After killing inferior, print our
2333 current frame in the core file, if we have one.
2334 (generic_mourn_inferior): When inferior dies, either select
2335 the current frame (in the new target, e.g. core file), or
2336 set both the current and selected frames to NULL.
2338 Changes from Peter Schauer.
2340 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2342 * Make all file names fit in 14 characters (sigh and damn!):
2343 mv hp300hpux-xdep.c hp300ux-xdep.c
2344 mv symmetry-xdep.c symm-xdep.c
2345 mv symmetry-tdep.c symm-tdep.c
2346 mv convex-opcode.h convx-opcode.h
2347 mv tm-vxworks960.h tm-vx960.h
2348 mv tm-vxworks68.h tm-vx68.h
2349 mv Makefile.srcdir Makefile.sdir
2350 mv gdb-int.texinfo gdbint.texinfo
2351 mv remote-sa.m68k.shar rem-m68k.shar
2352 mv remote-multi.shar rem-multi.shar
2353 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2354 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2355 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2358 * command.c (user_info_1, user_info): New command for listing
2359 the user-defined commands.
2361 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2363 * dbxread.c (really_free_pendings): Clear file_symbols
2364 and global_symbols after freeing them; otherwise, running
2365 this function twice (if it appears twice on the cleanup
2366 chain), we try to free things twice.
2368 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2369 based on text_addr (the address of text in core), not on addr (the
2370 offset between text in the .o file and in core). This change
2371 is from Peter Schauer.
2373 * main.c: Define ALL_CLEANUPS as a cast of zero.
2374 (return_to_top_level): Use it.
2375 (main): Do all cleanups after each command run as part
2376 of the gdb startup sequence. Also do all cleanups before
2377 entering the command loop, and every time we exit the command
2378 loop and reenter. Before, the cleanups from the startup sequence
2379 were being left undone until the first error!
2380 (command_loop): Rename do_nothing cleanup to command_loop_marker
2381 so we can see it easily when examining the cleanup chain.
2382 (init_signals): Add another do_nothing for signal handling.
2383 (quit_command): Only try to kill target if it has execution.
2384 Problems in the target stack got us into a state where
2385 inferior_pid was nonzero but none of the targets had execution.
2386 In this state you couldn't exit gdb.
2388 * dbxread.c: Two changes from Peter Schauer.
2389 (echo_command): Fflush output after an echo command.
2390 (show_history): Pass all args to cmd_show_list.
2392 * utils.c (init_malloc): Call mtrace to turn on tracing
2393 if the environment variable MALLOC_TRACE is set to a file name.
2394 * mtrace.c: Add source file which provides a log of every malloc,
2395 free, and realloc to a trace file.
2396 * mtrace.awk: Add source file which analyzes the trace file.
2397 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2398 (VERSION): Roll to 3.94.3.
2400 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2401 (check_duplicates): Don't bother with watchpoints.
2402 (set_raw_breakpoint): Comment about danger of this routine.
2403 (watch_command): Parse and eval all args before calling
2406 * solib.c (find_solib): Avoid error in referencing memory to
2407 see if any more shared libraries have been added. This is
2408 particularly useful if the target has terminated. Bug reported
2412 in bringing up 3.94.2 on the Sun-3.
2414 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2415 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2416 expression (in scope) before reenabling watchpoint.
2417 * signame.c (init_sigs): Add missing declaration of i, fix
2418 sys_siglist declaration.
2419 * source.c (list_command): Fixed range computation to use
2421 * stack.c (backtrace_command): Do not allow command if target has
2422 no stack, print informative error message.
2423 * target.c (target_command): Do not write into command line
2424 because this fails if the target command is used in a user defined
2425 command. [This change was enhanced by gnu to support any-
2426 unique-prefix matching on target names.]
2427 * valops.c (value_struct_elt): Avoid infinite loop on an
2428 erroneous attempt to print the member of function (try p main.p).
2430 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2432 * expread.y (name_no_typename): Avoid reduce/reduce errors
2433 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2434 Since the GDB parser really doesn't use name_no_typename in a
2435 name-only context, the parser can't tell the diff between
2436 names and numbers here. Avoid allowing a name_no_typename
2437 to be a NAME_OR_*INT to resolve the conflict.
2439 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2443 * valprint.c (val_print_fields): bitfield printing didn't handle
2444 byte order. Indirect through a few more fns to cope.
2446 * values.c (modify_field): also cope with byte order.
2448 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2450 Cleanup for release 3.94.2:
2452 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2453 include files. Roll version to 3.94.2.
2455 * coffread.c (init_stringtab): Read length into unsigned char
2456 array before swapping; don't assume 32-bit longs.
2458 * target.c (target_info): Don't bother with get_sym_file, just use
2459 the symfile global variable.
2460 * symtab.h, symfile.c (get_sym_file): Delete it.
2462 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2463 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2464 (read_type): Replace one more error() with complain().
2466 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2468 * i960-tdep.c: Fix copyright attribution.
2470 * config.gdb: Quote all backquotes in doublequotes. You can
2471 quote me on that. BSD 4.4 shell found this one.
2473 * infptrace.c (throughout): The third argument to ptrace is an
2476 * infrun.c (wait_for_inferior): When program has terminated, we
2477 have to call target_terminal_ours before we pop that target off
2478 the stack (e.g. before a call to target_kill or
2479 target_mourn_inferior). This fixes problem where a program
2480 terminates, then GDB stops for (tty output) and you have to type
2481 "fg" to the shell to resume it. FIXME: This code for what to
2482 do after termination really should be in normal_stop instead.
2484 * gdbcore.h (read_memory_check): Change declaration; it changed
2487 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2488 4.4 prereleases, this avoids a bug in their sgtty compatability
2490 * remote.c: Use terminal.h rather than hand-rolling the same.
2492 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2493 * utils.c (strsave, strstr): Fix arg types.
2494 * valprint.c (val_print): lint
2496 MIPS symbol table support from Per Bothner:
2498 * symfile.c (symtab_fns): Remove initializer table that needs to
2499 be hacked for each new symbol file format supported.
2500 (add_symtab_fns): New function, chains symbol table
2501 handlers into the global list.
2502 (symfile_init): Search this list.
2503 * symfile.h: Add next pointer, declare add_symtab_fns.
2504 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2505 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2507 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2508 symbol *). Thus, we no longer need the hack to trash
2509 pst->filename. Good, since that hack confused code in symfile.c!
2511 (reorder_symtabs, destroy_all_symtabs): Removed static
2512 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2513 Instead, the latter now uses a temporary array (stack-allocated
2514 from an obstack, and then freed).
2516 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2517 haven't been set in the outermost stBlock of a procedure. This was
2518 a problem with f77 binaries on Ultrix 4.?.
2520 (new_symtab, new_symbol, new_type): Continue changing code to use
2521 obstacks more and otherwise conform to dbxread internal style.
2522 Made the free_code of symtabs be free_linetable (as in dbxread)
2523 instead of free_contents. This implies memory leaks when reading
2524 a new symbol table, until the conversion is finished. Did change
2525 (struct symbol) and (struct type) to be allocated on the
2526 symbol_obstack. Blocks and blockvectors are among the things
2529 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2530 tested much, but it solved one problem (reported by Meissner), and
2531 cleans up some other things. The problem happened when an
2532 included file contains actual code (functions) and not just
2533 definitions. The mips coff is a little inconvenient there, since
2534 it may cause a procedure to be mapped to the wrong psymtab.
2536 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2537 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2538 this will need work for the new core paradigm.
2540 Opcode patches from the net:
2542 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2543 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2544 missing altogether - they are added here. From Bruce Bauman.
2545 * mips-opcode.h: The low mask for C0 instructions was too small.
2546 From Garrett Lau. I modified the fix to check the entire 32-bit
2549 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2552 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2554 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2556 * dbxread.c (read_type): Pointer subtraction (value_sub in
2557 valarith.c) sometimes failed because the types of the
2558 pointers being subtracted were not identical.
2559 These differed because dbxread.c was allocating pointer types
2560 using dbx_alloc_type+smash_to_pointer_type instead of
2561 lookup_pointer_type. I failed to find a justification for the
2562 former, so I changed it to use the latter. Similarly, I
2563 replaced smash_to_function_type by lookup_function_type,
2564 and smash_to_reference_type by lookup_reference_type.
2566 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2567 _initialize_mipsread): corresponding changes.
2569 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2571 * source.c (mod_path): Do tilde_expand on each component of the path,
2572 rather than on the (list of) paths as a whole.
2573 (print_source_lines): Set first_line_listed in addition to
2574 current_source_symtab and current_source_line. If the source was
2575 not findable, after a "dir" command to fix the problem,
2576 a "list" would get the wrong lines.
2578 While I was there... (gnu):
2580 * dbxread.c (read_type): Change error to complaint.
2582 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2584 First attempt at detailed understanding of symbol table memory alloc.
2586 * dbxread.c (dbx_symfile_read): Free our string table if we
2587 aren't the mainline. Free the "info" struct since we're done with
2589 (init_psymbol_list): Free any previously allocated psymbol lists.
2590 (): FIXME: Should realloc-down the psymbol lists when done reading
2591 the main symbol file?
2593 * symmisc.c (free_symtab): Free fullname field too.
2595 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2596 (REGISTER_ADDR): Make result type unsigned int.
2598 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2599 define REGEX must also define REGEX1 (its dependency).
2601 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2603 * tconfig/i960: No longer works, points you at vxworks960 or
2606 * xgdb.c, XGDB-README: Remove file. Users can get the much
2608 * Makefile.dist: Remove all trace of xgdb.
2610 * breakpoint.c (breakpoint_1): Pass demangle arg to
2611 print_address_symbolic.
2612 (clear_breakpoints): Remove unused function.
2613 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2614 (breakpoint_re_set): Use catch_errors to do them all anyway.
2616 * gdb-int.texinfo (Host versus Target): Add section on what is
2617 a "host" feature versus what is a "target" feature.
2619 * infcmd.c (path_command, path_info): Handle the PATH variable
2620 (object search path) as conveniently as the source search path.
2621 * environ.c (set_in_environ): Set some vars in GDB's environment,
2622 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2623 * source.c (mod_path): New function, from guts of
2624 directory_command, modifies a path. Used by path_command.
2625 (directory_command): Call it.
2626 * defs.h (strsave): Declare.
2628 * utils.c (sevenbit_strings): Add new printing option.
2629 (printchar): Use it.
2630 (strsave): Provide this handy helper routine.
2631 (set_width_command): Rename set_screen_width_command.
2632 (_initialize_utils): "set screen-width" => "set width";
2633 "set screen-height" => "set height"; add sevenbit-strings.
2635 * infcmd.c (do_registers_info): Print floating point registers
2636 in raw hex as well as float format, regardless of whether it is
2637 a "virtual" convertible register.
2638 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2639 regs as a double, just in case it's being used that way.
2640 * values.c (unpack_long): Comment on array/function coercion.
2641 (unpack_double): Argument is in target byte order now. For
2642 integer arguments, just call unpack_long and float the result.
2643 * m68k-tdep.c: include defs.h for "const" handling.
2644 * remote-nindy.c: Use ieee-float stuff.
2645 (nindy_fetch_registers): Unpack double regs to host double, then
2647 (nindy_store_registers): Pack extendeds to host double, flip
2648 around by misusing unpack_double, send as target double.
2650 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2651 zero, as when stopped at the first instruction of a process.
2653 * blockframe.c: Fix filename in comment (param.h => tm.h).
2654 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2655 * tm-68k.h: Fix typos.
2657 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2659 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2661 * coredep.c (fetch_core_registers): Pass end-address of register
2662 section to register_addr as expected. Don't call supply_register
2663 if we'd just pass it garbage.
2665 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2667 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2669 * target.c (push_target, target_info): Cast enums to int for < or
2672 * stack.c (print_frame_info): Identify source file & line
2673 even if we can't print it.
2675 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2677 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2679 Clean up IEEE floating point support.
2681 * ieee-float.h: New file.
2682 * ieee-float.c: Write real routines to convert between host
2683 doubles and various target IEEE extendeds.
2684 * m68k-xdep.c: Eliminate assembler code for extended floats.
2685 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2686 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2687 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2688 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2689 double_to_ieee_extended.
2690 * i960-tdep.c: Define ext_format_i960.
2691 * m68k-tdep.c: Define ext_format_68881.
2692 * sparc-tdep.c: Define ext_format_sparc, though unused.
2693 * Makefile.dist (HFILES): Add ieee-float.h.
2694 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2697 Obsolete the "coffstrip" program in favor of using BFD's strip.
2699 * nindy-share/coffstrip.c: Remove file.
2700 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2701 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2702 * tconfig/nindy960: Remove reference to coffstrip.o.
2704 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2706 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2709 * dbxread.c: Remove static symfile_bfd.
2710 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2712 * inftarg.c (child_detach): Pop the child_ops vector if the
2713 detach is successful.
2714 * remote-nindy.c (nindy_create_inferior): Don't push a new
2715 nindy_ops since nindy uses the same one for execution and memory
2717 * core.c (core_ops): Use child_attach and child_create_inferior
2718 rather than default attach and create_inferior functions.
2720 Handle floating point registers in core files.
2722 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2723 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2724 This version untested since BFD doesn't yet support sun3 core
2726 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2727 conventions. Fix comments and style. This version has not
2728 been compiled yet, since we have no HP inhouse.
2729 * core.c (get_core_registers): Look for two sections, ".reg"
2730 and ".reg2", and pass both to fetch_core_registers sequentially.
2732 Revise directory path yet again.
2734 * source.c (forget_cached_source_info): Not static any more.
2735 (init_source_path): New default source path is "$cdir:$cwd".
2736 (dir_command): Handle variable arguments ($cdir, $cwd).
2737 (source_info): Print "Compilation directory" rather than
2738 "Originally compiled in" to remind people of $cdir.
2739 (openp): If the path contains $cwd, use current directory.
2740 (open_source_file): If compilation directory is known, replace
2741 first $cdir in path with the compilation directory.
2742 (print_source_lines): Even if we can't print the lines, set the
2743 current symtab and line for future commands like "info source" or
2744 "breakpoint". Also, error message now contains the file name,
2745 line number, and file access error message.
2746 (_initialize_source): Fix help text to describe changes.
2747 * main.c (cd_command): Forget cached source info when we chdir.
2748 * utils.c (strstr): Add simple implementation.
2750 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2752 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2753 Byte-swap COFF symbol tables if necessary when reading them in.
2754 Use complain() to replace error message in one spot. Needs
2755 corresponding change in bfd/coff-code.h to make some symbol
2756 swapping routines non-static.
2758 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2760 Merge changes from Eirik Fuller, for UTek.
2762 * defs.h (errno): Add declaration.
2763 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2764 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2765 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2766 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2767 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2768 declarations of errno.
2770 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2772 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2773 <rpc/rpc.h> and <rpc/types.h>.
2775 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2777 * i960-tdep.c (examine_prologue): Add new argument limit,
2778 which stops the scan at the end of the prologue, or at the PC.
2779 This fixes a problem where it walks down into the code for the
2780 user's statements if that code looks like function prologues.
2781 Mark Fox and I have been bouncing this code back and forth, making
2782 small changes to it. Callers changed to match.
2784 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2786 Cleanup for gdb-3.94 release final:
2788 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2789 the .c files from vx-share and nindy-share, from the various
2790 macros, since they are not found via ALLDEPFILES.
2791 (SFILES): Add tm-i960.h.
2792 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2793 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2795 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2796 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2798 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2800 * am29k-tdep.c: Add contribution line.
2801 (examine_prologue): Cache information about function prologues in
2802 the misc-function-vector to avoid lots of references over the
2803 serial line while examining instructions.
2805 * core.c (core_close): New function made from cleanup_core.
2807 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2808 remote-vx.c, remote.c, target.c, target.h,
2809 Update target_ops vector to add attach, close, and load entries.
2810 Use add_syms_addr_command, not add_file_addr_command, for
2811 add_file. Break out close routine from existing code.
2813 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2814 they are in an obstack.
2815 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2817 (define_symbol): Add symbol type parameter; change callers;
2818 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2819 it to influence the symbol class on the i960.
2820 (define_symbol): Swap LOC_CONST's into target byte order.
2822 * exec.c (exec_close): New function.
2823 (exec_file_command): Call it.
2825 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2826 Fix byte order of frame pointer.
2827 (read_var_value): Result of 0 if var's value can't be found,
2828 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2829 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2830 (locate_var_value): Use read_var_value and use its lazy address
2831 as the location of the var's value. Lint.
2833 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2836 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2837 obsolete Intel versions in favor of vxgdb versions.
2838 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2839 code dealing with byte order of values, which Intel did in host byte
2840 order rather than gdb-4's target byte order.
2841 (i960_frame_chain_valid): Move to nindy-tdep.c.
2842 (examine_prologue, skip_prologue, frame_find_saved_regs,
2843 frame_args_address, leafproc_return, saved_pc_after_call,
2844 pop_frame): Add vxgdb versions from Mark Fox.
2845 (examine_prologue, frame_struct_result_address): Add code
2846 to deal with the saved value of G13 (struct return address
2848 (frame_args_address): Modify Mark's version to prefer the
2849 saved value over the current value in the topmost frame.
2850 Cache result in the frame info to avoid performance hair in
2852 (print_fault): Add gdb960 code for printing faults.
2853 (_initialize_i960): Actually call check_host.
2855 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2856 add stub routines. FIXME, these currently just return zero!
2858 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2859 (attach_command): Call target_attach, not target_open, now.
2861 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2862 (child_attach): Rename from child_open.
2863 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2864 don't confuse it with a zero step_resume_break_address.
2866 * inftarg.c (child_detach): Eliminate inferior_pid test.
2867 (child_files_info): Clean up message a bit.
2868 (child_ops): Use child_attach, not child_open, to attach.
2870 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2871 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2872 findvar.c to here, since it depends on the contents of the
2873 shadow_contents of breakpoints, but keep if #if 0 since it is
2876 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2879 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2880 (ptype_command, display_command): Eliminate have_inferior_p and
2881 have_core_file_p in favor of target_has_stack or
2882 target_has_execution.
2883 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2884 code for actually finding the values of arguments, though we still
2885 keep track of the maximum stack offset for use in printing unnamed
2886 arguments. Handle missing FRAME_ARGS_ADDRESS.
2888 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2889 (struct nindy_regs): Define registers passed to/from nindy.
2890 (nindy_fetch_registers, nindy_store-registers): Translate between
2891 nindy and GDB formats for the registers.
2892 (dcache_init): Statically allocate the cache, since it was being
2893 allocated by a malloc that was never freed anyway.
2894 (nindy_create_inferior): Error, not core dump, if no exec file.
2895 (nindy_before_main_loop): Use target_load, not target_add_file.
2897 * remote-vx.c (net_load): Specify large timeout for load
2898 requests. Allow user to break out with INTERRUPT.
2899 (net_break): Remove useless code, clean up. Change callers.
2900 (parse-args, skip_white_space, find_white_space): Clean up arg
2901 parsing to cope with quoted strings.
2902 (net_wait, net_quit): Never call error, just return status.
2903 (vx_read_register, vx_write_register): Cleanup status checking.
2904 #ifdef the code based on which CPU we are using (960 or 68k),
2905 FIXME, this should be completely general but it isn't yet.
2906 (vx_xfer_memory, vx_resume): Cleanup status checking.
2907 (vx_run_files_info): Improve message.
2908 (vx_load_command): Renamed from vx_add_file_command. Allow load
2910 (net_ptrace): Remove unused routine.
2911 (vx_wait): Adopt code from vxgdb960 to cope with broken
2912 connections to target machine and prompt to disconnect. Remove
2913 debug printouts. Map some EVENT_'s to SIGnals.
2914 (add_symbol_stub, vx_open): Print names of object files we found,
2915 and "ok" if we read their symbols OK. Clarify output in general.
2916 (vx_attach, vx_detach, vx_kill): Add these commands.
2917 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2918 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2919 "info files" output, and create_inferior, since we already have
2922 * stack.c (frame_info): Replace Frame_unknown with 0.
2923 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2924 (return_command): Pop until the PC matches as well as the FP,
2925 so it works even if the FP is shared with another function,
2926 as in "frameless" or "leaf" procedures.
2928 * symfile.c (load_command): renamed from add_file_target_command.
2929 (add_syms_addr_command): renamed from add_file_addr_command.
2930 (add_syms_command): Stub to call target_add_syms.
2931 (_initialize_symfile): Change command names and descriptions,
2932 add-file => add-syms, and load from alias to its own command.
2934 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2935 maybe_kill_then_create_inferior): Default for attempts to start
2936 a process, if one is already running, is to ask about killing
2937 it and retry if yes.
2938 (upstack_create_inferior): #if-0 it, strata obsolete it.
2939 (push_target, unpush_target, pop_target): to_close() a target
2940 before unstacking it.
2941 (target_info): Renamed from target_files_info.
2942 (_initialize_targets): Rename "i files" as "i target", accessible
2945 * target.h: Improve comments about the target_ vectored routines.
2947 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2948 Convert commenting style to standard GNU style.
2949 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2950 (SKIP_PROLOGUE): No longer a no-op.
2951 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2952 (*_REGNUM): Sort register numbers.
2953 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2954 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2955 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2956 are now 10 byte extendeds, not 8 byte doubles.
2957 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2958 for nindy versus vxworks targets. FIXME, this should possibly go
2959 in the target vector.
2960 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2961 frame_saved_regs and arg pointer with each frame.
2962 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2963 (FRAME_ARGS_ADDRESS): Use cached result.
2964 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2965 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2966 (PRINT_RAMDON_SIGNAL): Call print_fault.
2967 (POP_FRAME): Now works.
2969 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2970 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2971 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2972 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2975 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2976 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2978 * valarith.c (value_subscripted_rvalue): Avoid handling
2979 floats and doubles specially; it gave alignment errors. Lint.
2981 * valops.c (value_of_variable, value_of_this): Error if unknown
2984 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2985 to avoid alignment problems.
2986 (value_print): Handle unknown value address.
2987 (cplus_val_print): Two args are ignored; remove them. Change caller.
2988 (val_print): Use unpack_long rather than pointer-deref.
2991 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2992 to avoid alignment problems.
2993 (value_being_returned): Error if return value unknown.
2994 (set_return_value): Add bogosity warning, FIXME. *
2996 * TODO: A woman's work is never done.
2998 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2999 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3000 Add ieee-float.o to OBS.
3001 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3002 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3003 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3005 Changes to generalize the VxWorks RPC protocol slightly, to handle
3006 i960 as well as 68000.
3008 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3009 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3010 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3011 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3012 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3013 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3014 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3015 so they will move in target byte order rather than network
3016 byte order (happens to be the same).
3018 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3020 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3022 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3025 Add contribution lines to various files, showing where they
3028 * breakpoint.c (break_insn, check_break_insn_size,
3029 read_memory_nobpt): Remove to mem-break.c.
3031 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3034 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3035 entry has bad register number. This change is not
3036 tested in this release, FIXME.
3038 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3041 * value.h: Force value's contents field to be aligned to hold
3042 at least a double or a long long (if supported). This avoids
3043 doing bcopy's in and out of the contents field.
3045 (step_1): Avoid coredump under obscure circumstances when we
3048 * symtab.h (misc_info): Add field to misc function vector for
3049 any kind of cached information the target code desires. AMD
3050 29000 uses this to avoid repeating examine_function_prologue's.
3052 * coffread.c: Lint. Remove static symfile, read_section_header.
3053 core.c (have_core_file_p): Lint: remove.
3054 expprint.c (print_subexp): Lint.
3055 infptrace.c, valops.c, valprint.c: lint.
3057 Roll in changes from vxgdb-5.0.1:
3059 * symtab.h: Comment byte order of each address class. Add
3060 LOC_LOCAL_ARG for frame-relative args (960).
3061 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3062 symtab.c, symmisc.c: ditto.
3064 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3066 * remote.c (remote_resume): Error if resume with a signal.
3068 * symfile.c (prim_record_misc_function): Clear misc_info.
3069 (fill_in_vptr_fieldno): Check stub type of arg.
3071 * valops.c (value_cast): Avoid looking up names of types whose
3072 name we don't know, to prevent coredump. Sun CC produces typedef
3073 rtx and the name of *rtx is zero...
3075 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3077 Roll in changes from final AMD 29000 port (Tiemann).
3079 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3080 for ../include/a.out.encap.h. This might not work now that BFD
3081 is separately compiled. Instead, BFD support for encap will have
3082 to translate machine type 29k into the right COFF_MAGIC.
3084 * infcmd.c: Remove references to inferior_pid that aren't used
3085 in actual ptrace calls; use target_has_execution, etc.
3086 (have_inferior_p): Remove function.
3087 (program_info): Print target info rather than "process number";
3088 avoid gratuitous messages unless from_tty.
3089 (run_stack_dummy, finish_command): Set proceed_to_finish.
3090 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3091 main.c: Lint. Lose have_inferior_p().
3092 inferior.h (have_inferior_p): Remove, lint.
3093 (proceed_to_finish): Add flag to ask that all regs be saved
3094 by normal_stop, for the few commands that need it, speeding up
3095 serial I/O. Add comments to stop_registers.
3097 * remote-eb.c: Remove newline from breakpoint message we grep
3098 for. Never time out when running the user program.
3102 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3104 Roll in changes from vxgdb-5.0.1:
3106 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3107 symbol in its raw form, we are processing an unlinked ".o" file.
3108 See if the target environment has assigned it an address, using
3109 target_lookup_symbol (VxWorks does), and enter it into the symtab
3112 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3113 68k versions for a simpler version that assumes zero FP at bottom.
3114 Fixes bug of truncated stack reports.
3116 * target.h (target_lookup_symbol): Define this routine's args
3117 and result, finally.
3119 * target.c (nosymbol): Default routine for target_lookup_symbol.
3120 (target_default): Default lookup_symbol and call_function too.
3121 (files_info): Only print has_all_memory warning if a non-dummy
3124 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3125 vx_convert_from_virtual): If target does not have floating point,
3126 zero register "values", and avoid doing cross-net conversions.
3127 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3128 (vx_open): Rearrange code that attaches to target and reads
3129 symbols for all loaded modules, to work if some of the modules
3130 are not accessible. Add symbol_stub() and add_symbol_stub()
3131 as callbacks from catch_errors(). Allow connect attempt to be
3132 interrupted painlessly with ^C (FIXME, there are still some bugs
3133 if the interrupt happens during symbol reading.). Print
3134 final message with puts_filtered, since symbol messages are
3139 * main.c (catch_errors): Only print errstring if non-null.
3140 (command_loop): Avoid an ioctl per command to test ISATTY.
3142 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3143 (vx_xfer_memory): Return correct result!
3144 (vx_files_info): Indicate whether target has float or not.
3145 (vx_lookup_symbol): Complain, not error, if target gone.
3146 (vx_open): Print "Connected" msg before disabling immediate-quit.
3147 [FIXME: lookup_symbol and vx_open changes need testing.]
3149 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3150 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3151 contributor lines and update copyrights to 1991.
3153 Changes from an attempted H-PUX host port:
3155 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3156 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3157 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3158 * remote-vx.c: include <sys/time.h> for HPUX.
3159 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3160 "core_file_command" routine to BFD regime. May not work yet.
3162 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3164 * xgdb.c: Replace X10 version with some VJ version.
3165 (FIXME: Its copyright assignment is not on record.)
3166 * xgdb.c: Update include files to X11R4 (Xaw crud).
3167 (xgdb_display_source, create_text_widget): fix call to
3168 get_filename_and_charpos. Rewack source window stuff for X11R4
3169 (gleaned from include files, and "nm's" of binary libraries, since
3170 I had no doc available).
3171 (append_selection, append_selection_word): Disable with FIXME
3172 since R4 changed interface here.
3173 (create_buttons): Add back the old set of buttons.
3174 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3176 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3177 Roll VERSION to 3.94 (not yet final though).
3179 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3181 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3182 obstack_int_grow, obstack_int_grow_fast): Eliminate
3183 cast on left of assignment, which gives MIPS cc fits and is
3186 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3187 F_ALIAS. Use printf, not fprintf, when not passing a file
3189 (compare_opcodes): Check that identical instructions have
3190 identical opcodes, complain otherwise.
3192 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3193 was reported by Roland McGrath.
3194 (unimp): Only match if exactly zero instruction. (Roland)
3195 (branches and traps): Generate all variations of these
3196 instructions with macros, based on a single call that defines
3197 each condition name and its binary representation.
3198 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3200 * valprint.c (val_print_fields): Take, and use, format parameter.
3201 This means that "p/x struct" again prints the elements in the
3202 desired format. Changed callers.
3204 * stack.c (frame_info): Use filtered output, and indicate wrap
3205 points. Remove kludgy formatting designed to avoid line wrap.
3207 * utils.c (wrap_here): If the line is already full (because
3208 we had printed a long indent or long wrapped string), do an
3209 immediate newline-and-indent.
3211 * m68k-pinsn.c (print_insn_arg): Bugfix from
3213 instruction is incorrectly disassembled as bkpt #8.
3215 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3217 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3218 and then will dump core (sometimes). I traced it back to an
3219 uninitialized symfile_name in psymtab_to_symtab.
3220 (const_vol_complaint): Add quotes to message.
3221 (define_symbol): Only believe line number if gcc_compiled.
3222 Avoid allocating symbol if we will not return it.
3224 Add target strata support so that newly established targets go
3225 into their right place in the target stack (e.g. a new exec file
3226 doesn't wipe out the ability to access the running process).
3228 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3229 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3230 and initialize it properly in all the targets.
3232 * target.h: Document strata. Change return type of push_target.
3234 * target.c (nomemory): new function for dummy memory access.
3235 (tcomplain): Rename complain, now also used in symfile.c.
3236 (push_target): Push targets within strata. New return value shows
3237 whether new target is on top of stack or not. Always keep dummy
3239 (target_files_info): Ignore dummy target.
3241 * core.c (core_open): Warn user, and skip accessing file, if the
3242 core target is not the topmost target in the stack.
3243 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3246 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3247 target_ops, it doesn't belong there since we have no regs there.
3248 Change name of target from machine => memory to clarify.
3250 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3252 * Freeze version 3.93 for release.
3254 * Makefile.dist: Handle vx-share and nindy-share subdirs
3255 properly when building gdb.tar.Z.
3257 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3258 printed in various places, so I could change just one copy.
3260 * dbxread.c, coffread.c: Change references to bfd->iostream
3261 to cast to FILE *, now that BFD avoids needing types defined
3262 in other header files.
3264 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3266 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3267 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3268 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3269 (actually gcc -Wall).
3271 * dbxread.c: Remove first_global_sym, last_global_sym, since
3272 they are never referenced.
3274 * defs.h (baud_rate): Declare.
3275 main.c: Define it, and add the -b option to set it.
3277 * gdb-int.texinfo: Add text on how to define a new host or target
3278 architecture, prompted by Per Bothner's questions about MIPS
3281 * gdb.texinfo: Document "complaints". Change doc of -q since
3282 gdb no longer prints the copyright and blurb if you specify a file
3283 name to be debugged (just like Emacs). Add doc for Nindy-specific
3284 command line flags for specifying target serial port and such.
3285 Update copyright to 1991.
3287 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3288 has taken over for us the job of ripping up executable files. The
3289 crud caused Per Bothner's port to not compile.
3291 * infrun.c (normal_stop): Avoid printing "Program exited
3292 normally" if we are in batch mode. This allows a GDB which
3293 executes a program on a target system, to behave like a Unix
3294 command (input from stdin, output to stdout, no extraneous
3297 * main.c (main): Allow additional machine-dependent command line
3298 options to be specified with the ADDITIONAL_OPTIONS,
3299 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3300 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3301 processing to occur just before the main loop with
3302 BEFORE_MAIN_LOOP_HOOK.
3303 (main): If a "core file" argument is specified, and it is not a
3304 core file, try it as a process ID to attach.
3305 (symbol_completion_function): Attempt to cope with
3306 "show screen-" TAB, not very successfully. This needs more work,
3308 (batch_file): New function, returns whether we are reading
3309 commands from an interactive tty on stdin, or from somewhere else.
3310 Called by normal_stop since it doesn't get from_tty passed down
3311 to it like many commands do.
3313 * remote-nindy.c: Handle command line options for nindy
3315 (nindy_before_main_loop): Prompt user for tty name if they
3316 don't specify it before getting to the interactive command loop.
3318 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3319 and -r command line options. Also add hook before main loop
3320 to make it easy to specify a tty.
3322 * TODO: More things to do, one done.
3324 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3326 * dbxread.c: Make complaint() calls pass pointer, not struct.
3327 Add complaints about badly formatted C++ type information
3328 (const/volatile indicator, and parse errors resulting in
3329 error_type). Fix C++ virtual member fn comment.
3330 (read_struct_type): Avoid bumping pointer if we got a parse
3331 error; this prevents our walking beyond the end of a string.
3332 Terminate loop on null char as well as semicolon.
3333 (process_one_symbol): Fix the LBRAC fix so that it uses the
3334 last previous SLINE, FUN, or SO record's PC address. C++ debug
3335 symbols did not have SLINE records in a useful order compared
3336 to the LBRAC records.
3337 (define_symbol): Handle "catch" records.
3339 * symtab.c (check_stub_type): Added new complain
3340 `stub_noname_complain' and added a consistency check to
3341 keep the debugger from crashing when finishing from an
3342 exception frame. A real fix will be needed later.
3344 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3346 * infcmd.c (attach_command): Make global.
3348 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3349 but make them easy to comment out. Perhaps later they should
3350 be enabled by what CPU you configure for? FIXME.
3351 (VERSION): Roll to 3.93.
3352 (pinsn.o): Remove rule for obsolete file.
3353 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3355 Run down a problem that manifested by printing the wrong function
3356 name in stack traces of read_ofile_symtab. Turned out that the
3357 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3358 the LBRAC symbol with an address in the *data* segment, which
3359 blew our binary search through the blocks.
3361 * dbxread.c: Use the complain() facility consistently to bitch
3362 about problems in the symbol file we are reading.
3363 (finish_block): Add code to check the nesting of the blocks;
3364 complain and Procrust them to fit if wrong.
3365 (make_blockvector): Check the order of the blocks, complain
3366 [but don't cope] if wrong.
3367 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3368 symbols to be sure their PC value is greater than the last SLINE
3369 (line number) symbol we've seen, complaining and adopting the
3370 SLINE PC value if wrong.
3372 * symfile.h (struct complaint, complaint_root, complain,
3373 clear_complaints): Add.
3374 * symfile.c (complain, complaint_root, clear_complaints): Add
3375 facility to deal with non-fatal complaints and to regularize their
3377 (symbol_file_add): Clear complaint counters to allow new complaints.
3378 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3380 * dbxread.c (dbx_symfile_read): Remember the address and size
3381 of the string table for the main symbol file, so we won't read it
3383 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3384 to avoid reading the string table yet again. Lint.
3385 (throughout): Improve filtered output, including word wrap.
3386 (read_range_type): Improve Bothner's fix to handle other types too.
3388 * utils.c: Improve line wrap implementation. Handle unlimited
3389 width by making chars_per_line unsigned.
3390 (puts_filtered): New, easy, function.
3392 * defs.h (puts_filtered): add.
3394 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3395 call the identical sort_symtab_syms() in symfile.c instead.
3397 * expread.y: Suggest the `file' command rather than `symbol-file'.
3399 * command.h (enum var_types): Add zinteger for seroable
3401 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3402 nested if's into a switch.
3404 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3405 we did not stop because of a breakpoint (it must have been for
3406 some other reason, like a "stepi"), so don't print anything.
3408 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3409 doesn't include <sys/types.h>, old SunOS's require it for
3414 A test port of gdb-3.92.6 to the Sony NEWS.
3417 Don't normally link in remote- or vx stuff.
3418 Some of it doesn't compile, and it wastes space for 99% of the users.
3419 Remove reference to no-longer-used HAVE_VPRINTF.
3420 Fixed BFD_DEP typo to BFD_DIR.
3422 Fix cast in arg to bfd_h_getlong.
3423 Make char *prefix be const.
3424 Fix how certain range types are mapped into builtin unsigned int types.
3426 Remove 2 #includes. They cause errors (on Sony, at least),
3427 and aren't needed (they wern't in earlier versions).
3429 print_address_symbolic should never demangle labels
3430 (since it prints *assembler-level* labels).
3432 [This was superseded by the change to printcmd below.]
3435 Add some "volatile" return types to avoid warnings.
3436 If MISSING_VPRINTF add vprintf function and not just macro
3437 (since vprintf is used in printcmd.c).
3439 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3440 (The latter isn't grokked by some PCC-based compilers.)
3442 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3444 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3445 * nindy-share/coffstrip.c
3446 Added some forward declarations (otherwise, gcc complains
3447 about implicit extern redefined as static).
3449 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3451 Changes inspired by Per Bothner:
3452 * printcmd.c (print_address_symbolic): Take additional parameter
3453 specifying whether to demangle.
3454 (print_address): Pass in asm_demangle to control demangling.
3455 (print_address_demangle): New fn, takes explicit arg to control
3457 * utils.c: Add new vars demangle and asm_demangle, and let them
3459 (fputs_demangled): If !demangle, just print the argument.
3460 (fprint_symbol): If !demangle, just print raw symbol.
3461 * valprint.c (val_print): Call print_address_demangle rather than
3462 print_address, to cause demangling to depend on the global
3463 rather than assembler-level demangling setting.
3464 * WHATS.NEW, gdb.texinfo: Document.
3466 * main.c (show_command): Show all settings if no arg.
3467 (initialize_main): Make "info set" the same as naked "show".
3468 * command.c (cmd_show_list): Handle prefix commands in the
3469 list, and print the name of the setting as well as its English
3470 description and value.
3472 Allow gdb functions to specify where a line should wrap if it
3473 exceeds the size of a terminal line. Use it to make the output
3475 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3476 of the right size when screen width changes.
3477 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3478 (wrap_here): New fn, indicates a point in the output where we
3479 should wrap the line rather than just letting it overflow at a
3481 (fputs_filtered): Implement wrapping.
3482 (n_spaces): New fn, returns a pointer to N spaces.
3483 (print_spaces_filtered): Use n_spaces.
3484 * defs.h (n_spaces): Declare.
3485 * stack.c (print_frame_info): Wrap with 4-space indent after
3486 fn name and before filename and line number.
3487 * printcmd.c (print_frame_args): Wrap with 4-space indent
3488 before each argument name is printed.
3489 * valprint.c (value_print): Wrap with no indentation before
3491 (val_print_fields): Wrap with indentation relative to nesting
3492 level before each field name.
3493 (val_print): Wrap with nesting indentation before array elements.
3494 * command.c (do_setshow_command): Avoid extra newlines,
3495 wrap with 4-space indent around values printed, end with period.
3496 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3498 * breakpoint.c (breakpoint_1): Implement addressprint for
3499 "info breakpoints" display. Change file name and line number
3500 format to " at file:nnn" rather than " (file line nnn)".
3501 * gdb.texinfo: Document.
3504 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3506 Frozen for gdb-3.92.6 release.
3508 README, WHATS.NEW: Update for 3.92.6 release.
3510 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3511 coffread.o from configs since it is now built by default.
3512 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3513 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3514 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3515 from configs since it is now built by default.
3517 Makefile.dist: Update for release 3.92.6. Handle files that
3518 have been moved to ../include, ../getopt, or ../bfd. Add
3519 saber.suppress and tests directory. Add config.status to
3520 the release (it will say "none").
3522 coredep.c: Minor formatting fixes.
3524 These changes were made in early December but only checked in now:
3525 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3526 nindy-share/nindy.c: lint
3527 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3528 register values coming back from the target; we store values
3529 in target byte order everywhere.
3531 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3533 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3535 * valprint.c (cplus_val_print, val_print_fields): New functions,
3536 which print C++ objects. They conspire to avoid printing a
3537 virtual base class more than once, following all the twists and
3538 turns of C++ virtual base rules.
3539 (val_print): Call the above rather than do it by hand.
3541 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3542 symbol file, not for added files like shared libs. This really
3543 needs to be generalized to a timestamp per file.
3545 * core.c (cleanup_core): Avoid coredump if no core file.
3547 * config.gdb: Accept -host or -target in place of +host or
3550 * coffread.c (find_linenos): Avoid desupported BFD interface
3551 to line numbers. We still read them manually rather than using
3552 BFD's "generic" features.
3554 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3556 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3558 * Makefile.dist: Eliminate use of $< in explicit targets.
3560 * readline/Makefile: Use $< rather than $*.c, which does not
3561 include the VPATH in GNU Make.
3563 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3564 copies of tconfig/i960, added for global configuration
3565 compatability. All i960 versions can read both coff and b.out.
3567 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3568 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3571 * TODO: Think of more things to do.
3573 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3575 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3576 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3577 64-bit float conversion.
3579 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3580 equivalent to sun?os4 so global config works.
3582 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3586 * main.c: Only declare linesize once; declare pagesize not at
3587 all, since it is never used.
3588 (main): Clear newly allocated line before it is used.
3590 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3592 Further stabilization for the Intel 960.
3594 * Makefile.dist: Parameterize the location of the "include"
3595 and "bfd" directories, as well as "getopt". Add symfile.c.
3596 Link in both dbxread and coffread. Fix up "make depend" to
3597 rewack the locations of include, bfd, and getopt in its output.
3599 * README: Document moving include files, improve some of
3602 * coffread.c: Move common code out to symfile.c. Change
3603 symbol_file_command style interface to use new *_symfile_init
3604 and *_symfile_read interface under BFD. Use BFD internal
3605 info to locate line table, symbols, etc.
3607 * core.c (core_fetch_registers): Rename to get_core_registers
3608 to avoid confusion with fetch_core_registers.
3609 (register_addr): Move to coredep.c, which is already machine
3610 dependent. This leaves core.c pretty clean of dependencies.
3612 * coredep.c (register_addr): Accept this routine from core.c.
3614 * dbxread.c: Move common code (with coffread.c, etc) into new
3615 symfile.c. Each psymtab now contains a pointer to the
3616 format-dependent function that knows how to read it in. Make
3618 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3619 (process_one_symbol): Add code to complain about a "compiler bug
3620 we muzzle here", if we actually see it.
3622 * eval.c (evaluate_subexp): Insert missing "break" statements
3623 in code that determines whether a variable is an lvalue in
3624 memory, register, or whatever. I detected this via a compiler
3625 bug in which it *almost* mashed out the whole switch statement.
3627 * gdb-int.texinfo: Add minor sections on configuring gdb for
3628 release, and about the README file.
3630 * infcmd.c (registers_info): Fix formatting somewhat. Still
3631 not as pretty as before, but it handles byte swapping.
3633 * remote-nindy.c: If data cache routines are interrupted while
3634 waiting for the remote end, be sure that any uninitialized cache
3635 blocks are on the free list, not on the valid list!
3637 * symfile.h: Flesh out this header file with all the various
3638 routines and variables that have been merged in from dbxread.c
3639 coffread.c, and symtab.c to symfile.c.
3641 * symfile.c: New file, containing code common to dbxread.c,
3642 coffread.c, and some code from symtab.c. All generic code for
3643 reading symbol files should be in here now.
3644 (unrecord_misc_function): Remove unused function.
3646 * symtab.h: Remove file-reading things to symfile.h.
3648 * symtab.c: Remove file-reading things to symfile.c.
3650 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3651 to decode i960 fault types.
3653 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3654 target.c: Change type of the "resume" function from int to void,
3655 since its result was never used.
3657 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3659 * main.c: Replace "stupid" with "caution"; you now "set caution
3662 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3664 * infcmd.c (do_registers_info): Call val_print to deal with the
3665 byte order of the registers being printed. FIXME, this makes
3666 the formatting of the output uglier.
3668 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3669 defined, call it for signals the debugger doesn't itself use.
3670 The i960 uses this for more detailed fault information.
3672 * remote.c (remote_open): If arg is null, print help rather than
3675 * sparc-xdep.c (register_valid): Avoid declaring size, since
3676 various modules will think of various sizes depending on the
3677 architecture of their tm-file. FIXME, we need protection against
3678 actually entering one of those modules, which would clobber
3679 storage if not for the target architecture compiled into gdb.
3681 * stack.c (up_command, down_command): Always print the frame
3683 (up_silently_command, down_silently_command): New commands
3686 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3688 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3689 more parameters than it used to.
3691 * findvar.c (registers): Increase slop to 256 bytes, which should
3692 protect us against even most RISC machines with large register
3694 (locate_var_value): Move declaration inside related ifdef.
3696 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3697 throughout, to avoid throwing away buffered input from the board.
3698 (nindy_wait): Supply_register takes addr_of_value, not value.
3699 (i960_print_fault): Renamed from i80960_fault.
3700 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3701 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3703 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3704 we can set the PC in the call to proceed(). Unpush nindy_ops
3705 before pushing it on top, to avoid message to user. Eliminate
3706 commentary from Unix machines that just misleads here.
3707 (reset_command): Fix error message to suggest target command.
3709 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3711 Release 3.92.5 as frozen.
3713 Stabilize the merged release...with help from lint, Saber C,
3716 Everywhere: Add include files needed to declare return types
3717 of functions called.
3719 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3721 * breakpoint.h: Add undeclared breakpoint functions, and some
3722 functions for display handling since I couldn't think of a better
3725 * breakpoint.c (insert_breakpoints): Make code for disabling
3726 shared library bkpts more likely to work. It's used when we
3727 rerun a program and stop before the shared library has been
3729 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3730 cast from pointer, so it squeezes through catch_errors.
3731 (bpstat_stop_status): Fix logic broken some time ago. We now
3732 always create a bpstat if the stop address matches a breakpoint,
3733 even if we don't stop there -- just like the old code used to do
3734 before I got my fingers into it (sigh).
3735 (breakpoint_1): Print "ignore count" after "stop only if"
3736 condition, since that's how it actually works.
3737 (mention): Handle watchpoints as well as breakpoints.
3738 (watch_command): use set_raw_breakpoint and mention to do most
3739 of the work (and initialize all the fields!). Only pass one
3740 arg to parse_c_expression, since that's all it takes.
3742 * command.c (not_just_help_class_command): Rename arg to args
3743 since we ignore "unused argument" warnings on vars named "args".
3744 inflow.c (child_terminal_info): ditto.
3745 infptrace.c (kill_inferior): ditto
3746 main.c (catch_errors, version_info, quit_command, pwd_command,
3747 source_command, dump_me_command, editing_info,
3748 set_history_size_command, set_history, show_history,
3750 stack.c (locals_info): ditto
3751 target.c (target_files_info): ditto
3752 valprint.c (set_input_radix, set_output_radix): ditto
3754 * core.c: Remove old variables for handling core and exec file
3755 sections (data_start, data_end, stack_start, stack_end,
3756 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3757 text_end, exec_data_start, exec_data_end, text_offset,
3758 exec_data_offset, data_offset, stack_offset). They're
3759 superseded the more general build_section_table and
3761 (get_exec_file): Mention the `file' command.
3762 (read_memory_check): Rename to memory_error, and only call it
3763 in the case of an actual error.
3764 (read_memory, write_memory): call memory_error.
3765 (core_fetch_registers): Register section name is ".reg".
3767 coredep.c: Remove a bunch of crud now that all this file does
3768 is pull the registers out of a core file.
3769 (fetch_core_registers): Rewrite to actually work, I hope.
3771 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3772 Replace index() with strchr(). Remove all the pre-BFD macro
3773 definitions for accessing the symbol file.
3774 (struct dbx_symfile_info): Encapsulate the information that
3775 dbx_symfile_init needs to pass to dbx_symfile_read in this
3778 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3779 dbx_symfile_discard): Rearrange symbol file reading to divide
3780 the format-specific part from the format-independent part,
3781 leaving the format-independent part such as file name expansion
3782 and opening in symtab.c. This replaces
3783 partial_symbol_file_open and partial_symbol_file_read.
3784 Symbol_file_read, add_file, add_file_target_command,
3785 add_file_addr_command move to symtab.c. Pass an explicit
3786 "mainline" flag for when reading the main symbol table, rather
3787 than relying on the offset address to be zero or nonzero.
3789 (dbx_symfile_read): Don't allow void *'s to be printed as
3791 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3792 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3793 macro" debug version really work.
3794 (read_dbx_symtab): Remove unref'd parameter inclink.
3795 Avoid swapping N_SLINE symbols, for speed.
3796 Merge N_TEXT!N_EXT case with the other external symbol
3797 definitions' case. Add comments.
3798 (start_psymtab): Allocate the symfile name in the psymtab on
3799 the psymbol_obstack, rather than using the caller's storage.
3800 (end_psymtab): Only allocate a dependencies list if there are
3802 (psymtab_to_symtab_2): Use BFD when reopening file to read
3803 its symbols for real.
3804 (read_struct_type): Add FIXME comments where it needs work
3806 (read_huge_number): Add FIXME about overflows.
3807 (read_range_type): Add FIXME about comparing a long to 1<<32.
3809 * coffread.c: Minor changes to move things closer to the new
3810 regime with symtab.c and dbxread.c Major work is still needed
3813 * exec.c (exec_file_command): Remove old variables (see core.c
3815 (xfer_memory): If memory transfer is right at the end of a
3816 section, don't lose.
3818 * findvar.c (get_saved_register): If value is in a real
3819 register, LVAL is lval_register, not lval_memory.
3821 frame.h: Declare print_sel_frame and record_selected_frame.
3823 gdb-int.texinfo: New file, for GDB internals documentation.
3824 Very simple, unformatted doc of cleanups is there for now.
3826 gdbcore.h: Remove obsolete variables that described a.out
3827 section addresses and offsets. (See core.c above.)
3828 Declare fetch_core_registers and registers_fetched.
3830 getopt.c: Declare char *alloca(); even on SPARC.
3832 infcmd.c (run_command): Call target_kill rather than
3834 (step_command, next_command, stepi_command, nexti_command):
3835 Declare from_tty parameter even though we don't use it.
3836 (run_stack_dummy): argument BUFFER is a char array, not
3837 a pointer to REGISTER_TYPE.
3838 (finish_command): using_struct_return needed a value *,
3839 not a struct symbol *.
3841 * infptrace.c (child_xfer_memory): To avoid dependency on
3842 where sections are in memory, try PT_WRITE_D and if that fails,
3843 try PT_WRITE_I. Most Unixes don't care which you use.
3845 * infrun.c (step_resume_break_shadow): Change to array to
3846 match other breakpoint shadow storage.
3847 (clear_proceed_status): Pass address of bpstat to
3848 bpstat_clear, not the bpstat itself.
3849 (child_create_inferior): FIXME comment about if the child
3851 (start_inferior): Remove old function.
3852 (child_open): Use target_kill rather than kill_inferior.
3853 (wait_for_inferior): Ditto.
3854 (insert_step_breakpoint, remote_step_breakpoint): Use
3855 new step_resume_break_shadow.
3857 * inftarg.c (child_wait): If all child processes die,
3858 pretend that the one being waited for exited with signal 42.
3860 * main.c (command_line_input): When scanning for comments,
3861 don't coredump on unclosed quotes.
3862 (quit_command): Use target_kill rther than kill_inferior.
3863 (_initialize_main): Rename class_user from "user" to
3866 * printcmd.c (print_command_1): Initialize "fmt" if no format
3867 is specified by the user.
3868 (print_frame_args): Only add to args_printed if we are
3869 actually fetching args from the stack (avoiding undefined
3871 (_initialize_printcmd): Remove bogus \{ from string.
3873 * remote-eb.c (eb_open): Avoid coredump on no argument.
3875 * remote-nindy.c: Bring out of Intel environment into new
3876 target environment. Remove all conditional compilation on
3877 I80960. Massive hacking throughout.
3878 (nindy_xfer_inferior_memory): New routine stolen from
3880 (nindy_create_inferior): New routine pieced together, probably
3881 not quite working yet.
3882 (nindy_ops): New target_ops struct for nindy.
3884 * remote-vx.c: Use write_memory rather than target_write_memory
3885 to get error checking.
3886 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3888 (vx_create_inferior): Use target_terminal_ours...
3890 * signame.c (_initialize_signame): Always initialize, since
3891 we need the table for things other than psignal.
3893 * solib.c (solib_add): Use symbol_file_add, not add_file.
3894 (solib_address): Return boolean result rather than struct
3895 pointer which nobody else knows the type of.
3897 * sparc-tdep.c, valops.c: Use write_memory rather than
3898 target_write_memory, to get error checking.
3900 * stack.c (locals_info, catch_info, args_info,
3901 get_selected_block, frame_command, up_command): Use
3902 target_has_stack, rather than have_inferior_p or
3905 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3907 * symfile.h: New file, defining the interface between the
3908 generic and object-file-specific symbol reading code.
3910 * symtab.c: Move generic symbol-reading interface to symtab.c,
3911 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3912 table to map BFD targets to symbol-reading modules in GDB.
3913 Change index to strchr.
3914 (lookup_struct_elt_type): Use error() rather than hand-made
3915 simulations thereof.
3916 (lookup_partial_symbol): Speedup slightly when length == 0.
3917 (symbol_file_add): New function.
3918 (symbol_file_command): Call it.
3919 (symfile_open, symfile_init): New function.
3920 (add_file_target_command, add_file_addr_command): moved from
3923 * target.c (target_command): use target_kill.
3925 * target.h (target_files_info): Don't declare, never called
3928 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3929 files to determine stack end address.
3931 * valarith.c (value_x_binop, value_x_unop): Change error message
3932 to be more useful. Pass proper argument to value_struct_elt.
3934 * valops.c (value_assign): FIXME comment that long long
3935 bitfields will break here.
3937 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3938 Update `make saber_gdb' to work better.
3940 * TODO: A woman's work is never done.
3942 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3943 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3944 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3945 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3946 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3947 valops.c, valprint.c, exec.c: Lint.
3950 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3952 Continuing Intel 960 port merge of GDB.
3954 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3955 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3956 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3957 Wack over "make depend" so it handles files in subdirectories
3958 vx-share, nindy-share, bfd, and in the current directory.
3960 * blockframe.c (get_prev_frame_info): Remove fatal error
3961 if stack not defined.
3963 * core.c (core_open, core_detach): New functions that handle
3964 the old "core-file" command as "target core" and "detach" instead.
3965 (core_file_command): Call them.
3966 (core_xfer_memory): Use common routine xfer_memory.
3968 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3969 dbxread now uses bfd for everything but symbol reading itself.
3970 BFD internals are used to drag out the relevant file offsets.
3971 (partial_symbol_file_open): Change args all around for BFD.
3973 * symtab.c: Rename "value" to "val" everywhere, so we can
3975 (symbol_file_command): New command, moved from dbxread.c
3976 and coffread.c. It uses BFD to read the file, then vectors
3977 based on its type, to dbx or coff symbol readers.
3978 * symtab.h: Extern a few vars for symbol_file_command.
3980 * target.h: Breakpoint takes a char * save area, not a char **.
3982 * valprint.c (val_print): When unpacking bitfields, offset
3983 the address in gdb of the value, if it is declared with a shorter
3984 type. Remove the last "runtime kludge test" of host byte order.
3986 * utils.c: Remove old my_bfd_read routine.
3988 * stack.c (frame_info): Use target_has_stack. Print program counter
3989 register's actual name rather than "pc", since it's called the
3990 "ip" (instruction pointer) on the i960 (sigh).
3992 * target.c (target_command): Add command for selecting a target
3993 type and calling its open routine. This is used for initiating
3994 communication with a particular target, in a generic way.
3996 * tm-i960.h: Update for modern gdb. Remove semicolons from
3997 various macros. Handle reading struct return convention, and
3998 error-out attempts to return structs with the "return" command.
3999 Be sure gdb doesn't think we know how to call functions in the
4002 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4003 to i960_xxx in lower case.
4004 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4005 not being defined yet.
4007 * remote.c (remote_open): Call start_remote to initialize
4008 wait_for_inferior during open.
4009 (remote_xfer_inferior_memory): Return length written rather
4012 * remote-vx.c (target_command -> vx_open): Use new generic
4014 * remote-eb.c, inftarg.c, exec.c: ditto.
4016 * infrun.c: Fix comments.
4017 (attach_program -> child_open): Use new generic target command.
4018 (wait_for_inferior): Clear saved register values before target_wait,
4019 so target_wait can set some of them if convenient.
4021 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4022 Return success indicator, not void.
4023 (child_xfer_memory): Avoid fetching initial word if we'll
4024 overwrite it anyway.
4026 * infcmd.c (attach_command): Use new generic target open routine.
4027 (_initialize_infcmd): Update doc on attach and detach commands.
4028 (do_registers_info): Merge in a byte-order problem as a FIXME
4031 * findvar.c (find_saved_register): Avoid problem in current frame.
4032 (read_relative_register): Ditto.
4033 (write_register): Convert byte order on the way out.
4035 * exec.c (file_command): Add.
4036 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4037 (xfer_memory): Common function between core_xfer_memory and
4039 (exec_xfer_memory): Use it.
4041 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4043 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4044 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4045 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4047 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4049 Merge Intel 960 port of gdb, continuing...
4051 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4052 symbol_file_command): Pass from_tty arg to hush 'em up.
4054 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4055 Add magic numbers for 960 COFF format.
4057 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4059 Merge Intel 960 port of gdb, from Intel "1.2" release.
4061 CHANGE_LOG entries from their port, which was based on
4064 Thu Sep 6 11:02:22 PDT 1990
4065 Remove temp file if download is interrupted.
4067 Wed Aug 1 09:08:33 PDT 1990
4068 Now uses binary protocol to talk to NINDY.
4069 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4070 Times out after 5 seconds when trying to talk to NINDY.
4072 Tue May 29 12:54:49 PDT 1990
4073 Added variable baud rate (-b switch).
4074 Source code reorganization.
4076 Thu Apr 26 11:09:55 PDT 1990
4077 More cleanup of batch mode; specifically, execute "-s", "-e", and
4078 "-se" switches as soon as they are encountered on the invocation line.
4080 Fri Apr 20 13:47:15 PDT 1990
4083 Thu Apr 19 09:54:28 PDT 1990
4084 Add 'reset' command.
4086 Wed Apr 18 09:48:07 PDT 1990
4087 After opening remote tty, wait for 1 second to go by without input
4088 from it before trying to talk to NINDY (fixes problems with the
4089 Heurikon HK80/V960E).
4091 Mon Apr 4 16:33:05 PDT 1990
4092 Some output was not being suppressed in 'batch' mode.
4094 Thu Mar 22 15:31:11 PST 1990
4095 Ask user if old symbol table should be deleted when new file is
4098 Allow user to run a program downloaded before gdb960 was brought up.
4100 Correct "exec-file" help message for i80960 context.
4102 Correct bug in calculating user space address: could occasionally
4103 corrupt user program.
4105 Make sure to zero low-order bits in rip's because of bug in 960CA
4106 A-step part: could cause operation faults when "next"ing across
4109 Correct bug that made it impossible to get source line numbers for
4110 code loaded at addresses higher than 0x7fffffff.
4112 Wed Jan 10 12:43:22 PST 1990
4113 Open remote tty for exclusive use.
4115 Fri Jan 5 12:14:42 PST 1990
4116 Correct disassembly (CA manual was right after all):
4117 opcode for sysctl is 0x659
4119 Mon Oct 23 12:03:04 PDT 1989
4120 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4122 Mon Oct 16 14:15:09 PDT 1989
4123 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4125 Mon Oct 2 15:56:31 PDT 1989
4127 Added 960CA disassembly support.
4129 To simplify maintenance:
4130 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4132 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4133 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4134 - made disassembly interface identical to that in gdmp960.
4138 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4140 * target.h: Allow targets to stack. Add target_has_memory,
4141 _registers, etc. Restructure memory access and "info files"
4142 to walk the target stack.
4143 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4144 target.c: Change tables to match target.h.
4145 * inflow.c (child_mourn_inferior): pop child_ops.
4146 (generic_mourn_inferior): Use new has_stack flag.
4147 * infptrace.c (child_xfer_memory): New memory regime.
4148 * inftarg.c (child_files_info): New "info files" regime.
4149 * remote-eb.c: New memory regime, new info files.
4150 * remote-vx.c: New memory regime, new info files. Now use
4151 separate targets for VxWorks attachment to machine, and
4152 actually running a process under VxWorks, since one has
4153 stack & execution & regs and the other doesn't.
4154 * remote.c: New memory regime, new info files.
4155 * sparc-xdep.c (fetch_core-registers): New memory regime.
4156 * target.c: New routines and support for stacked targets,
4157 new memory regime, new info files regime.
4160 Generalize section handling for an arbitrary number of sections,
4161 including use of the new BFD (binary file) library.
4162 * gdbcore.h: Add struct section_table.
4163 * exec.c (build_section_table): Iterate all sections and
4164 record what gdb needs to know about them.
4165 (exec_command): Use it.
4166 (exec_xfer_memory): Use the table.
4167 (exec_files_info): Print the table.
4168 * core.c (core_file_command, core_xfer_memory, core_files_info):
4170 * source.c (find_source_lines): Use bfd_get_mtime.
4171 * dbxread.c: Quick changes to make it compile with new BFD.
4172 * utils.c (error): Avoid using bfd_error in generic routines.
4174 * core.c (core_fetch_registers): Get from the ".regs" section of
4176 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4178 * inferior.h (attach_flag): Export.
4179 * infcmd.c (run_command): use new target_create_inferior.
4180 * infrun.c (child_create_inferior): Don't return result.
4181 * Makefile.dist (VERSION): 3.91.4.
4183 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4185 * breakpoint.c (bpstat_num): Handle breakpoints which have
4186 since been deleted, such as temporary breakpoints.
4187 infcmd.c (program_info): ditto.
4189 * core.c (core_file_command): Display the frame where the core
4194 * remote-vx.c (target_command): Merge in target command from
4195 targ-vx.c. A few other cleanups.
4197 * TODO, Projects: Lots more stuff to do...
4199 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4201 Massive changes to wall off the remote-debugging interface
4202 behind a function vector. The port to handle VxWorks targets
4203 is also part of this.
4205 All files: Replace references to renamed functions,
4206 remove references to remote_debugging, remove references to
4207 have_include_file, have_core_file in favor of target_has_stack,
4208 target_has_memory, etc.
4210 * Modularize the breakpoint interface.
4211 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4212 a breakpoint instruction.
4213 breakpoint.c: struct breakpoint's shadow_contents now sized as
4215 (insert_breakpoints): Vector to target to install breakpoints.
4216 (remove_breakpoints): Vector to target here too.
4217 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4218 sparc-tdep.c (single_step): Use new breakpoint interface for
4219 the single-step breakpoints.
4220 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4221 New file, contains routines to insert and remove breakpoints by
4222 reading out the old contents and later replacing them. This is
4223 how ptrace breakpoints work, and many remote systems as well.
4225 * tm-vxworks68.h: New config file, overrides a few things for
4226 Wind River's preferences.
4228 * target.h: New file, for transfer vector used to talk to the
4229 inferior (child, attached, core, exec, remote, etc). All accesses
4230 to the thing being debugged should come through these vectors.
4231 target.c: New file, routines to handle transfer vector.
4232 (various files): Add transfer vectors XXX_ops for the various
4233 targets and pseudo-targets (core files, etc) we support.
4235 * breakpoint.c (bpstat_stop_status): Further explorations of
4236 watchpoints and why things don't work all the time.
4237 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4239 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4240 the local gdbinit if it doesn't already have it.
4242 * core.c (core_ops): add and install.
4243 Allow core debugging without exec file.
4245 * dbxread.c (free_and_init_header_files): Merge two fns.
4246 (end_symtab): Free named symbol table when a new version comes in.
4247 (read_dbx_symtab): Relocate all kinds of symbols with base
4248 address. First step toward handling different text, data, bss
4250 (add_file_addr_command): Renamed add_file_command.
4251 (add_file_command): Vector to remote handler.
4252 Add "load" as an alias for "add-file" command.
4254 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4255 non-returning functions.
4257 * exec.c: Add exec_ops, and push it as a target when an exec
4260 * infcmd.c (run_command): Pass executable file name and arg list
4261 separately when starting an inferior. Permit "run" when no exec
4262 file is specified, for VxWorks.
4263 (detach_command): Move to child_detach in inftarg.c.
4265 * inftarg.c: New file. Unix-child-specific routines, and the
4266 child_ops structure.
4268 * inferior.h (registers): Export "registers" as the way for
4269 target dependent register handlers to find gdb's local copy of
4270 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4271 since it is now used by places that want wait_for_inferior to
4272 handle the grunge but want to see every trap from the inferior.
4274 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4275 Eliminate remote_debugging hooks in terminal handling.
4277 * infrun.c: Replace start_inferior with child_create_inferior.
4278 Move all the hair of Unix shells and ptrace idiosyncracies into
4279 child_create_inferior, so remote handlers don't have to deal.
4280 Remove running_in_shell. Rename stop_after_attach to
4281 stop_soon_quietly, and use it in a few other places where we want
4282 to just call wait_for_inferior and get control back on the first
4283 trap. trap_expected now never takes a value > 1.
4284 (init_wait_for_inferior): Initialize static vars when a new
4287 main.c (gdbinit): Add new hook for .gdbinit file name, let
4288 it be overridden by config files as GDBINIT_FILENAME.
4289 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4290 Both of these are used for VxWorks gdb.
4292 mcheck.c: rename include file "gmalloc.c" to avoid problems
4293 with system include file "malloc.c".
4295 param-no-tm.h: New include file, same as param.h but does not
4296 include the default "tm.h" file. This is used in files where
4297 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4299 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4301 remote-vx.c: New file, VxWorks remote debugging support. Uses
4302 RPC routines that are shared with the target system, in directory
4305 remote.c: Vectorize remote interface.
4307 source.c: Globalize source_path, and make an alias "l" for "list"
4308 since we now have the "load" command.
4310 sparc-xdep.c: Use new param-no-tm.h.
4312 symmisc.c (free_named_symtab): Add new function from Wind River.
4313 However, ifdef it out for now while we think about what it should
4316 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4318 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4319 non-Unix-children handle this with their own code in the target
4322 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4323 source and target lists. Add vx-share to default list of include
4324 directories. Add new files to src and target lists: mem-break,
4325 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4326 ${srcdir} versions of munch and createtags are used.
4328 * valops.c (find_function_addr): Split out of call_function.
4329 (call_function_by_hand): Rename call_function; this function
4330 calls functions in the target by laboriously patching the target
4331 word-by-word with the right stack, args, regs, etc.
4334 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4336 Handle AMD 29000 a bit better.
4338 * remote-eb.c (readchar): Mask received char log to make it readable.
4339 (remote_start): Pass arguments down to executing program.
4340 Make startaddr unsigned.
4341 infrun.c (start_inferior): Accept args, pass them to
4343 infcmd.c (run_command): Pass args down to start_inferior.
4345 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4346 the target object file format.
4347 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4349 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4350 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4352 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4354 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4355 * TODO: We did a few things, we have more to do though.
4357 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4358 * inflow.c (inferior_died): Clear deferred stores.
4360 * Debug problems with dummy frames and calls to the inferior.
4361 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4362 * sparc-tdep.c (do_restore_insn): Simplify.
4363 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4364 (sparc_push_dummy_frame): Simplify and fix what we push.
4365 (sparc_pop_frame): Slightly more hair here, deciding whether
4366 we are restoring a saved PC or returning to a return address in %i7.
4367 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4369 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4370 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4371 * obstack.h (chunkfun): ditto.
4372 * defs.h (xmalloc, xrealloc): ditto
4374 * utils.c (quit): Grab the terminal from the child if necessary.
4376 * inflow.c (term_status_command): Rename to term_info, change
4379 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4380 (is_delayed_branch): Speed up.
4381 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4382 Still missing some float ops, and needs testing.
4384 * Support for input and output radixes other than base 10
4385 * defs.h (input_radix, output_radix): Declare.
4386 * expread.y (yyparse, parse_number): Handle changes of input
4387 radix, and ambiguous names-or-numbers in radixes >10.
4388 * printcmd.c (print_scalar_formatted): Print formatted hex
4389 numbers in varying column widths.
4390 * valprint.c (val_print): Use output_format to print scalar ints.
4391 (set_input_radix, set_output_radix, set_radix): Create.
4392 (set_output_radix): Set output_format from output_radix.
4393 (_initialize_valprint): add `set radix' but leave the others off.
4395 * main.c (execute_command): Let stupid questions be turned off.
4396 (_initialize_main): Handle "set stupidity", etc.
4398 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4399 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4401 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4403 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4404 bfd stuff is still screwed up, but with some manual work, it
4407 * breakpoint.c (bpstat_do_actions): Start over if a command
4408 proceeds the inferior, since the inferior will have stopped and
4409 will need to have its new stop-actions taken care of.
4411 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4412 compiler fits, simplify it.
4414 * gdb.texinfo (directory command): Doc new dir command.
4415 source.c (directory_command): "dir" now puts things on the front
4416 of the path, moves dups up front, and handles multiple names
4417 on the command line, inserting each one in order. It also
4418 blows away cached line and full_filename info.
4420 * stack.c (backtrace_command): Skip "more stack frames follow"
4423 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4424 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4425 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4426 The only odd one was Gould NP1, which had defined vprintf to
4430 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4431 variable, inspect_it.
4432 valprint.c (print_string, val_print): Use the global inspect_it
4433 to indicate whether to print in Epoch style or normal style.
4435 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4437 * printcmd.c (call_command): add an alias for the "print" command
4438 which runs expressions and doesn't print the result if void.
4439 (print_command_1): implement it.
4441 * command.c: Remove #if 0'd code. Initialize all the fields
4442 in add_cmd (). Rename do_nothing_command to
4443 not_just_help_class_command, and make it externally visible.
4444 command.h: add user_commands to struct.
4445 * main.c (define_command): Don't overload c->function with a char
4446 string as well as a function pointer.
4448 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4449 calling convention of value_struct_elt () that got dropped in
4452 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4453 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4455 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4457 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4458 until a good time (e.g. when we are about to run the child),
4459 saving ptrace calls.
4460 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4461 * tm-sparc.h: define DO_DEFERRED_STORES.
4463 * sparc-xdep.c (store_inferior_registers): when storing float
4464 registers, don't store stack regs too. When storing the SP,
4465 however, DO store the stack regs too. This fixes a bug in which
4466 the dummy frame is not recognized when a call_function finishes,
4467 because its frame pointer (in the stack regs) was never
4469 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4470 even though we don't know how to read them from an inferior.
4471 valops.c (call_function): Comment about storing SP.
4473 * infrun.c (save_inferior_status): Save away the original bpstat
4474 chain so it can be restored later. Install the copied version for
4475 use by whoever saved the status. It will be blow away by
4476 restore_inferior_status, and the original chain restored. This is
4477 important for people who have pointers into the original.
4479 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4480 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4481 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4484 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4486 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4487 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4488 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4490 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4492 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4493 Store the baseclasses in a type struct starting from array element
4494 0 rather than from the unusual array element 1.
4496 dbxread.c: the above.
4497 (virtual_context): Add
4498 Read new debug information about which virtual function table
4499 a virtual function is from, and store it in fn_field.fcontext.
4501 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4502 TYPE_FN_FIELD_STATIC_P.
4504 symtab.c: the above.
4505 valops.c: the above. Handle pointer casts of object *'s.
4506 (search_struct_method): Add.
4507 (value_struct_elt): First arg is now a pointer to a value, and is
4510 valprint.c: the above.
4511 values.c (value_virtual_fn_field): Add type arg. Handle
4512 offsetting to the proper object when calling virtual fns.
4514 (baseclass_addr): Add valuep arg.
4516 * README: Document the current state of BFD config (missing).
4517 * TODO, ChangeLog, Makefile.dist: Roll version.
4518 * WHATS.NEW: Add summary of changes since 3.5.
4520 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4522 * dbxread.c (read_struct_type): Clear bit vectors whenever
4524 symtab.c (B_CLRALL): define.
4526 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4527 using == rather than =. Huh... This fixes the dreaded problem
4528 wherein builtin_type_int becomes TYPE_CODE_FLT.
4530 * core.c (info_files): Show the inferior pid.
4532 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4533 already knows how to look in the source directory.
4535 * Remove psymtab hair from many places. Remove duplicated code
4536 for searching symbol tables. Hide psymtabs from most places.
4537 Make it fast to get from a psymtab to its symtab.
4539 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4540 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4541 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4542 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4543 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4544 new symtab completely. New psymtabs get symtab pointer
4545 initialized to zero. Remove MI warning printf.
4546 symtab.h: Comments. Add psymtab to symtab pointer.
4547 (PSYMTAB_TO_SYMTAB): New macro.
4548 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4549 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4551 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4553 (print_frame_info): Avoid special-casing symbols that have not yet
4556 * source.c (open_source_file): Quick path if we have already
4557 located the source file by its full name.
4559 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4560 find_pc_psymtab. When a name is found in the misc function
4561 vector, search the symbol table for its mangled name, not the
4562 name that the user typed.
4564 * bfd.h: Fix missing comment terminators, make #endifs match.
4566 * valarith.c (value_less): Handle unsigned int comparisons.
4567 Add FIXME about pointer compares, which assume host and target
4568 pointers are the same.
4570 * command.c (do_nothing_command): lint
4571 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4572 fix comments on debug symbol format for visibility. Actually set
4573 visibility of symbols.
4574 main.c (echo_command): lint; use <readline/history.h>.
4575 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4576 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4577 pointing past end of allocated memory; saber complains.
4578 obstack.h: Declare the external functions that we use.
4579 valarith.h: use <string.h>
4580 solib.c (solib_add): lint.
4582 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4584 * main.c (initialize_main): Default info_verbose to off, now that
4585 symbol reading is fast.
4586 (quit_command): Avoid clobbering exec_bfd while quitting.
4588 * Initial BFD (binary file diddling library) merger:
4589 coffread.c: Change AOUTHDR to struct exe_hdr.
4591 core.c: initialize initialized data at compile time.
4592 (core_file_command): Move from coredep.c, convert to bfd.
4593 (xfer_core_file): Convert to bfd.
4594 exec.c (exec_file_command): use bfd routines.
4596 mips-tdep.c: Remove exec_file_command and friends.
4599 * coredep.c: (fetch_core_registers) Convert core_file_command to
4600 fetch_core_registers.
4601 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4603 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4604 (my_bfd_read): More bogosity, which I don't think we call.
4605 (program_name): Remove this atrocity asap!
4607 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4610 values.c: allocate_repeat_value was not clearing the
4611 optimized_out field.
4612 (value_static_field): minor stylistic fix (wrong macro was used).
4613 valops.c (value_struct_elt_for_address): didn't work for C++
4616 * signame.c (_initialize_signame): Initialize signal names once.
4618 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4619 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4620 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4622 * remote-eb.c: Support user-settable baud rates on the serial port.
4624 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4626 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4628 * tconfig/sun3os4: Remove warning about native assembler,
4629 since it also occurs in the xconfig file.
4631 * findvar.c (registers): Allocate some slop after `registers'
4632 to prevent stray accesses from trashing the next variable.
4634 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4635 on the sun-3, by changing the #ifdef from `sun3' (which is not
4636 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4637 vars, which happened to follow `registers' in the executable.
4639 * readline/history.c (history_search): Heed gcc-2's advice
4640 and parenthesize && inside ||).
4642 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4643 tm-29k.c: Insert FSF copyright headers.
4645 * remote-eb.c: Better comments.
4647 * Makefile.dist: Update to 3.91.6.
4648 * TODO: note PREPARE_TO_STORE problem.
4650 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4652 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4654 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4656 * infrun.c (wait_for_inferior, at end): Don't set up
4657 prev_* if the inferior no longer exists.
4659 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4660 CANNOT_EXECUTE_STACK.
4661 valops.c (call_function): Use it.
4663 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4665 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4666 infrun.c (wait_for_inferior, 2 places): Use it.
4668 * values.c (value_being_returned): Only use
4669 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4671 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4672 right thing for remote-eb.c.
4674 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4675 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4677 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4678 (FRAME_FIND_SAVED_REGS).
4680 * findvar.c ({fetch,store}_registers): Check for
4681 REMOTE_{FETCH_STORE}_REGISTER macro.
4683 * findvar.c (get_saved_register): Add argument lval and
4684 change meaning of argument addr.
4685 findvar.c: Change calls to get_saved_register to reflect
4686 new calling convention.
4687 valops.c (value_assign): Use get_saved_register instead of
4688 find_saved_register.
4690 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4692 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4693 an (uninitialized) pointer to one. Use "&" when passing it
4696 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4698 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4701 * coffread.c (symbol_file_command): Put semicolon after
4703 Put safe_to_init_tdesc_context in #if defined (TDESC).
4704 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4705 coffread.c: #include <sys/stat.h>.
4706 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4707 Add missing ')' in check for "lc%" and friends. Remove
4709 Declare read_one_sym() at top of file.
4710 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4711 MC68WRMAGIC can have the same value without causing a duplicate
4714 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4716 * Allow a Makefile to be built without building the
4717 tm and xm file links that screw up builds in subdirectories.
4718 This is done with `config.gdb none', then you can do things
4719 like `make gdb.tar.Z'.
4720 * tconfig/none: Config file for no target system
4721 * xconfig/none: Config file for no host system
4722 * config.gdb: If no TM or XM files are called out by the
4723 host or target file, don't make links for them.
4725 * cplus-dem.c: Add documentation.
4727 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4728 simple error, so the user's gdb doesn't crash due to some object
4729 file problem (e.g. somebody is rebuilding the file out from under
4732 * printcmd.c (print_address_symbolic): demangle the symbol.
4734 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4735 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4736 (alldeps.mak): sort and uniq all results from this; duplicates
4737 hose gdb.tar.Z link building. Remove RCS files from
4738 tconfig and xconfig. Add config files for sun386. Add
4739 a few odd files to OTHERS and HFILES.
4741 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4743 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4744 Roll version number to 3.91.5. Make lint work in bindir.
4746 * README: Document cross-debugging and new file structure.
4748 * blockframe.c: Lint. Include "value.h" to declare read_register.
4749 (find_pc_partial_function): remove duplicate line.
4751 * command.h: Lint. Declare error_no_arg and dont_repeat.
4753 * tm-news.h: Remove inadvertently duplicated stuff.
4755 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4756 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4758 * config.gdb: Allow `config.gdb host target' form. Clean
4759 up previous change that printed bogus messages when you just said
4762 * core.c: #include "command.h" for lint.
4765 * main.c: Remove some casts of enums. Lint.
4772 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4774 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4775 read it from memory. This will allow us to save ptrace calls
4776 eventually. Changed caller single_step too.
4778 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4779 that we aren't going to use, saving many ptrace calls, especially
4780 when watchpointing or single stepping. Use some #define's for
4782 (store_inferior_registers): Ditto.
4783 (core_file_command): Use some #define's for constants.
4785 * tm-sparc.h: Add #define's for some register numbers, so we
4786 can eliminate the use of random constants in sparc-xdep.c.
4788 * stack.c (frame_command, print_frame_info, up_command,
4789 down_command) Remove frame_changed, since it
4790 causes a bug and doesn't seem to do anything useful. In some
4791 places it was used as a flag, in others as a stack level (?).
4793 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4794 default is to use the portable (vprintf) version rather than the
4796 * xm-news.h (MISSING_VPRINTF): Add.
4798 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4800 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4802 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4803 about linking debugged programs -Bstatic in the sun?os4 config
4804 files in tconfig and xconfig subdirectories.
4806 * main.c (main): Remove unreached exit(0) now that we exit
4809 * Create TODO file for online bug list. There are too many
4810 "little" bugs to keep track of on paper.
4813 rather than kingdon@ai.
4815 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4817 * Makefile.dist (VERSION): 3.91.4 now.
4819 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4820 (condense_misc_bunches): Add sanity check that misc_count is
4821 the same as the number of symbols in the bunch.
4823 * coffread.c: rename init_misc_bunches. Pass an argument
4824 to condense_misc_bunches (a zero).
4826 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4827 every time we are called; don't rely on our caller to do it.
4828 (add_file): Remove call to init_misc_bunches.
4830 * mipsread.c: Only warn, don't error, if unknown symbol types.
4831 This keeps an old gdb from falling on its face if it sees newly
4832 extended symbol info. Rename init_misc_bunches.
4834 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4836 * Merge in changes from Per Bothner for DECstations and other
4837 MIPS stuff. The rest is Bothner speaking:
4839 The next message is a merger of Alessando Forin's mips port with
4840 mine. I've tried to use my good if biased judgment to get
4841 the best of both. It *does* need testing.
4843 Some of the changes are general, *not* mips-specific.
4846 Didn't believe in little-endian bit order.
4847 There are still inconsistencies about whether flags
4848 like BITS_BIG_ENDIAN are integer (#if ...) or
4849 boolean (#ifdef ...). I tried to paper over them.
4851 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4852 Moved some misc_function code that was common to
4853 {dbx,coff,mips}read.c to symtab.c.
4854 In the process, I think I cleaned things up a bit.
4855 At the same time, moved obsavestring and obconcat to symtab.c.
4858 Removed obsolete condense_addl_misc_bunches (use
4859 condense_misc_bunches(1) instead).
4862 Needed to include <sys/dir>, at least on DECstations.
4864 valops.c, mips-tdep.c, tm-mips.h:
4865 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4866 conventions (when STACK_ALIGN is insufficient).
4867 Needed on mips, where doubles need 8-byte alignment,
4868 but ints only need 4.
4871 Removed cruft that was not being used.
4875 Print $ before register-names (I think that makes things a little
4877 Never print two instructions, even if one delays.
4878 Removed hex-disassemble set_cmd. (This is not mips-specific,
4879 so I think the argument is whether it is generally worthwhile or not.
4880 I'm inclined to think not, given how easy it is to
4881 convert between radixes in gdb.)
4884 This is basically Alessando's code.
4885 It doesn't use obstacks; I changed it to use obstacks
4886 in a few minor places where using malloc causes a
4887 memory leak. (Probably, more places could/should be changed.)
4888 I added record_misc_function where it was missing.
4889 In symbol_file_command and add_file_command, I tried
4890 to make the code consistent with more recent versions.
4891 Minor sylistic changes in parse_procedure.
4892 Make a .gdbinfo. psuedo-symbol point back to the real
4893 procedure symbol (using the isym field).
4896 This is basically from my port, but with a lot of details
4897 and a number of routines merged in from Alessando's version.
4898 I basically used my code "raw" backtrace (use heuristics
4899 from the actual code, rather than symbol table info) - though
4900 the idea is Alessandro's. I feel my code is a little cleaner
4901 here, particularly in being a little more flexible, such as being
4902 able to handle gcc-produced code (which it now can).
4903 It also doesn't do frame caching (which is not useful
4904 more recent gdb versions).
4905 I also used my code for push_/pop_dummy, more or less.
4906 I tried to incorporate AF's code for testing sigtramp
4907 while backtracing; I probably got it wrong.
4908 Added mips_print_register, which tries to scrunch as much
4909 information as possible on a screen...
4910 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4911 under mips-pinsn.c), I don't see anything mips-specific here,
4912 and I don't see it being all that useful anyway.
4915 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4916 Use more register names (rather than hard-cases numbers).
4918 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4920 * Hack up 3.90.11 changes:
4922 * Makefile.dist (depend): parameterize $(GCC).
4923 Add solib.c and solib.o.
4924 (readline): Fix vpath for both absolute or relative SRCDIR.
4927 Also, let the part I didn't understand at least compile so
4928 I can test the rest. FIXME.
4930 * dbxread.c: Fix thinko using strcmp.
4931 (init_psymbol_list): declare static.
4932 (partial_symbol_file_open): Comment cleanups better, avoid
4933 cleaning up the string table since the caller will do that.
4934 Move the stat for mod time into symbol_file_command, temporarily.
4935 (There should be a mod time for each symbol file, eventually,
4936 to control its rereading. FIXME.)
4938 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4939 SunOS, which gives error for shared libs otherwise. (From
4940 Schaefer, probably FIXME needs work for portability.)
4942 * solib.c: Move #include "param.h" to work.
4943 Lowercase all the Uppercase Letters In the Messages.
4944 (find_solib): Clean up inferior_so_name for debug printouts.
4945 Allow no argument, to mean all shared libraries.
4947 * symmisc.c: include param.h to get CLEAR_SOLIB.
4949 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4951 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4952 to 3.90.11. ChangeLog entries below are from this.

4973 Put parens around gcc_p in expansion.
4975 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4977 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4979 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4981 * Changes for Sun shared libraries:
4982 blockframe.c (find_pc_partial_function): If a non-text symbol
4983 is found, set *address = pc - FUNCTION_START_OFFSET.
4984 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4985 Disable breakpoints instead of giving an error.
4986 source.c (select_source_symtab): Initialize cs_pst.
4987 symmisc.c: Call CLEAR_SOLIB if defined.
4988 symtab.h: Make text{low,high} CORE_ADDR not int.
4989 (psymtab): New field addr.
4991 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4992 (record_misc_function): Give correct type for N_DATA symbols.
4993 (condense_misc_bunches): do "misc_function_count = j" regardless
4995 Take code which is shared between symbol_file_command and
4996 add_file_command and put it into partial_symbol_file_{open,read}.
4997 Split add_file_command into add_file_command and add_file.
4998 Make psymtab_to_symtab read in the string table if the file
5000 Two new parameters to read_dbx_symtab and start_psymtab.
5001 tm-sunos.h: New file.
5003 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5005 * infcmd.c: Change cont_command to continue_command and "cont"
5008 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5010 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5012 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5014 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5015 size 1,2,4,8 rather than size < 8.
5017 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5018 as necessary, not just once.
5020 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5022 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5024 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5026 * tm-news.h: Add CALL_DUMMY_*.
5028 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5030 * config.gdb: In list_host, list_target, use ${i}, not $i.
5032 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5034 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5036 * sparc-opcode.h: Change all store floating-point state register
5037 instructions to have the right match & lose fields.
5039 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5041 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5043 config.gdb: If srcdir != ., create readline directory and
5044 copy a makefile into it.
5046 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5047 consistency with POSIX.
5049 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5050 when we exit its exp_valid_block.
5052 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5054 * Makefile.dist: Bump version to 3.91.3.
5056 * Clean up handling of breakpoint commands (somewhat).
5057 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5059 inferior.h: Add breakpoint_proceeded to inferior status struct
5060 and globals; save it and restore it.
5061 (clear_breakpoint_commands): Cleanup, remove old #define.
5063 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5064 (save_inferior_status, restore_inferior_status): handle it also.
5065 (proceed): Remove earlier code that set breakpoint_proceeded.
5066 It is now set only in clear_proceed_status.
5067 (clear_proceed_status): Cleanup, use bpstat_clear rather
5068 than clear_breakpoint_commands. No callers need the stop_bpstat
5069 between clear_proceed_status and proceed.
5071 infcmd.c: Add breakpoint_proceeded definition and comment.
5072 (cont_command, jump_command, signal_command): Move call to
5073 clear_proceed_status right next to call to proceed.
5075 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5076 caller's argument while running down the chain of breakpoints.
5077 Use new variable "breakpoint_proceeded" to determine when
5078 a command that it executes moves the inferior past the
5080 (bpstat_clear): Handle NULL argument.
5081 (bpstat_clear_actions): Avoid useless call to
5082 breakpoint_auto_delete.
5083 (delete_breakpoint): Clean up bpstat's that are pointing to
5084 the deleted breakpoint from the stop_bpstat chain.
5085 (breakpoint_auto_delete): Simplify.
5087 * Clean up handling of EOF, error on stdin, etc. This was
5088 prompted by a network problem that caused gdb to go into an
5089 infinite loop filling up its malloc'd memory.
5091 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5092 not clear_breakpoints_commands, which is now gone.
5093 (main): If command_loop returns (e.g. from EOF on stdin), do
5094 a quit_command (looping back to command_loop if quit_command
5095 doesn't really quit).
5096 (command_loop): check result from command_line_input and
5097 exit if it returns NULL, rather than passing the NULL to
5099 (gdb_readline): Free malloc'd result space before returning
5102 * utils.c (query): Handle C-d to mean "yes", just as if the
5103 input was not a terminal. Also avoid infinite loop if EOF
5104 occurs in mid-input-line before newline. This allows
5105 query to be used at EOF on stdin with reasonable results.
5107 * infrun.c (proceed): Set breakpoint_proceeded.
5109 * values.c (value_as_long): Avoid infinite recursion for enums.
5110 (_initialize_values): Fix typo in help msg (kingdon).
5112 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5113 RL_LIB for linking. This allows -lreadline for linking
5114 and nothing for dependencies, once readline is a real library.
5116 * config.gdb: Jim Kingdon: give useful error message if the
5117 host or target type is not recognized.
5119 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5120 it just defines it. Dumb, but deal with it.
5122 * Jim Kingdon suggests:
5123 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5125 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5127 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5129 * Clean up Bothner's changes.
5131 * blockframe.c (clear_pc_function_cache): New function.
5132 * blockframe.c: remake cache_pc_function_* static.
5133 * dbxread.c (symbol_file_command): remove references to
5134 cache_pc_function_* variables.
5135 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5136 * printcmd.c: Avoid kludging a global variable (addressprint)
5137 to avoid printing the address of a string twice. Instead,
5138 pass the format letter 's' down low enough that it can be seen
5139 to avoid this problem.
5140 (print_formatted): Pass format arg to value_print.
5141 (restore_addressprint): Remove function.
5142 (do_examine): Avoid hacking addressprint, cleanups and such.
5143 (print_frame_args): Add a comment to a Bothner change.
5144 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5145 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5146 to wipe out the values cached in blockframe.c.
5147 * symtab.c (find_method): Add comment saying how big you must
5148 allocate to be "big enough". Per being terse again.
5149 * valprint.c (val_print): Handle format letter "s" to print
5150 strings without addresses. Add comment to vtbl printing code
5151 which casts with wild abandon. Rearrange reference-printing
5153 @0xaddr: value (print w/addressprint)
5154 value (print w/~addressprint)
5155 @0xaddr (parameter lists w/addressprint)
5156 or nothing (parameter lists w/o addressprint)
5158 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5160 * Merge more changes from Per Bothner:
5162 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5163 annoying) that I tried to improve it. Here are my suggestions.
5165 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5168 Do automatic de-reference when taking the address of a reference.
5170 Don't deref_ref when printing parameter lists.
5172 More attempts at treating refernences properly.
5174 In val_print, if deref_ref==0, don't print dangling " = ".
5176 Add COERCE_REF macro, which de-references an REF.
5178 * Merge changes from Per Bothner:
5180 * Fixed (Sony news)-specific configuration problems.
5181 * Fixed other problems with using vanilla pcc and libc (enum problems;
5182 assumption that vsprintf exists).
5183 * Some major speed-ups (finc_pc_partial_function now caches a match;
5184 parsing avoids duplicate symbol_lookup calls).
5185 * Changed handling of baseclasses (no longer use baseclasses field
5186 of struct type, use the first n_baseclasses fields instead).
5187 * Various minor changes/fixes, most C++-related.
5190 Cache the most previous match from find_pc_partial_function.
5191 (Save both low and high ends of matching function's pc range.)
5192 This speeds up the loop of infrun.c:wait_for_inferior quite
5193 a bit, and makes step/next commands much zippier.
5195 Added an enum->int cast (otherwise, some compilers barf).
5197 No longer set baseclass offset to 0, since multiple
5198 inheritance now mostly works.
5199 Added a number of casts, to shut up compiler warnings
5200 (after stabs where made enums, not ints).
5201 When discarding a symbol table (in symbol_file_command),
5202 must clear the cache introduced in blockframe.c.
5203 Don't convert $vtbl_ptr_type to vtbl any more.
5204 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5205 Mask off sign bit emitted by g++ for virtual table offset.
5206 Set voffset to -1 (not 1) for static member functions.
5208 Changed parsing/lexing of names to avoid doing symbol lookup twice
5209 (once when lexing to determine symbol class, once for real).
5210 Now only call symbol_lookup once. Fields of 'this' win especially big.
5212 Subpress printing addr twice in the case of 'x/s addr'.
5214 lookup_basetype_type is no longer used.
5215 Add find_methods as recursive helper function to decode_line_1.
5216 This allows multiple inheritance to work.
5217 Also, once one or more matches has been found, do not look in
5218 base-classes. (Baseclass methods would be overridden, anyway.)
5220 Removed baseclasses array in struct type.
5221 Instead of using baseclasses[i], use fields[i-1].
5222 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5223 Changed sign convention of voffset (previous was inconsistent).
5225 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5227 Used to assume existence of vsprintf. Re-written to not need it
5228 if HAVE_VPRINTF is undefined.
5230 typecmp was too pessimistic. Made it less so.
5232 Don't print space after address.
5233 If vtable points to a misc symbol (with 0 offset), print it,
5234 since that indicates the actual class of the object.
5235 Changed ype_print_derivation_info to use new inheritance
5236 scheme (without baseclasses vector).
5238 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5239 Also, changes needed because TYPE_BASECLASSES were removed.
5241 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5243 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5246 If there is no path set, and the symbols don't indicate what directory
5247 a file was compiled in, look in the current directory. But either
5248 a path or a known compilation directory will prevent this.
5251 Three independent bug fixes:
5252 * Remove the #if 0 block that breaks some stuff.
5253 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5254 adapt gdb to either SunOS 4.0.* or 4.1.
5255 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5258 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5261 (type_print) Demangle the name being printed.
5262 (type_print_base) Handle botched demangling without coredump (tiemann).
5265 (check_stub_method): Document routine.
5266 (tiemann) fix bug for no-arg functions
5267 Avoid clobbering beyond end of malloc'd storage.
5268 Terminate the argument list properly.
5272 * Changes merged by John Gilmore:
5275 In breakpoint_1, use new print_address_symbolic instead
5276 of find_pc_partial_function. (This forces use of assembler-level
5277 addresses, and avoids misleading non-mangled source-level names.)
5279 Generalize ansi argument such that -1 means skip arglist totally.
5280 Removed global variable print_ansi_qualifiers (which made
5281 code non-reentrant), in favor of extra explicit arguments
5282 to internal routines.
5284 Add new helper function print_address_symbolic.
5285 Use find_pc_misc_function instead of find_pc_partial_function
5286 (since we want assembler-level symbols here).
5288 Print unknown function as just "f (...)", not "f (...) (...)".
5289 Use new fputs_demangled explicitly.
5291 Fixed a typing violation (problem: value.h cannot be imported
5292 without renaming many variable in this file).
5293 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5294 decode_line_1: Moved forward some never-reached code.
5295 Made decode_line_2 skip function prologues correctly.
5297 fputs_filtered should not demangle by default.
5298 Add new fputs_demangled to demangle on demand..
5300 Change value_struct_elt to use value_primitive_field (using recursive
5301 utility function search_struct_field). This allows foo.bar to work
5302 for multiple inheritance (so far only for data fields).
5303 Change check_field in the same way (recursive helper function
5304 to support multiple inheritance).
5305 (Note: there are more of these problems that I haven't fixed.
5306 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5307 value_of_this: 'this' symbol name is now just "this", note "$this".
5309 Don't print static members.
5310 Avoid printing "members of <type>" if there are none.
5311 Simplified type_print_derivation_info by merging duplicate code.
5312 Remove useless blank lines in type_print_base (ptype command).
5314 Added declaration of new routine value_primitive_field.
5316 Added value_primitive_field which is generalized version of
5317 value_field that can handle multiple inheritance (non-zero offsets etc).
5318 Re-implemented value_field to call value_primitive_field.
5320 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5322 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5323 delete the whole environment. Karl Berry reported the bug.
5324 * source.c - fix openp to avoid //'s in filenames, which
5325 trigger an Emacs bug causing it to not be able to find files
5326 when running gdb in a window.
5327 * dbxread.c - zap the #if 0 that botches the add-file code.
5328 It seems to work a lot better without all the code commented out.
5330 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5332 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5335 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5337 * Makefile - added a ${CFLAGS} to a couple of entries,
5338 added remote-sa.sparc.c
5339 * added remote.sa-sparc.c, a modification of remote.c
5340 which conducts a dialog directly with the SparcStation prom.
5341 * breakpoint.c, infrun.c, sparcdep.c added
5342 remote_insert_breakpoint(), and remote_remove_breakpoint()
5343 to breakpoint.c instead of directly writing breakpoint instructions.
5344 * sparcdep.c on remote_debugging,there is no need
5345 to remove signle step breakpoint instructions.
5346 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5348 * printcmd.c - epoch interface sends lisp expressions to open up
5349 epoch windows on inspection.
5350 * valprint.c - added arrayprint, and addressprint and made adding
5351 format controls easier
5352 * wait.h added a couple of undef's because we were getting
5353 complaints about WSTOPSIG and WTERMSIG begin redefined.
5356 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5358 * symtab.c (decode_line_1): Add support for handling method stubs
5359 in the type information.
5361 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5363 * values.c (baseclass_addr): Run loop from INDEX+1 to
5364 N_BASECLASSES; otherwise, we can still get into a loop.
5365 @@ This should be restructured to use a cleaner search strategy.
5367 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5369 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5370 abbreviation "Tt" for tags which have the same name as their
5373 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5375 * symtab.c (list_symbols): add ability to set breakpoints on all
5376 the functions which match a particular regular expression.
5378 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5380 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5381 should print ANSI qualifiers (such as `const' and `volatile').
5382 All callers changed to call with ANSI == 1, except from
5383 `check_method_stub', which uses old-style syntax.
5385 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5386 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5388 * values.c (check_stub_method): New function.
5390 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5392 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5393 * valprint (type_print_base): Ditto.
5395 * symtab.c (gdb_mangle_typename): New function.
5397 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5399 * breakpoint.c (catch_command): New function. Provides a
5400 mechanism to set breakpoints based on catch clauses.
5401 (disable_catch): Similar, but disables breakpoints on catch
5403 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5405 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5407 * blockframe.c (blockvector_for_pc): New function.
5408 * blockframe.c (block_for_pc): Changed to call
5409 `blockvector_for_pc' and get the block itself.
5411 * stack.c (catch_info): New function. Prints info about
5412 exceptions which can be caught in the current frame.
5413 * stack.c (print_frame_label_vars): New function. Similar to
5414 `print_frame_local_vars'.
5415 * stack.c (print_block_frame_labels): Prints out labels that are
5416 defined in this frame. These labels are exceptions that can be
5419 * dbxread.c: Updated to handle N_CATCH symtab types.
5421 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5423 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5424 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5425 when printing the type.
5427 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5429 * valprint.c (val_print): Use `baseclass_addr' to access the
5430 baseclasses pointed to via the derived class object at VALADDR.
5432 * values.c (baseclass_addr): New function. Casts derived pointers
5433 to baseclass pointers taking virtual baseclasses and multiple
5434 inheritance into account.
5436 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5440 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5442 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5443 exp_valid_block field correctly.
5445 * infrun.c (wait_for_inferior): When checking "don't even think
5446 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5447 also check step_resume_breakpoint.
5448 Insert breakpoints and continue (not step) if
5449 step_resume_break_address != NULL, even if another_trap.
5450 If trap_expected and we enter sigtramp, then set up a
5452 If trap_expected is set when we hit the step_resume_break,
5454 When calling resume and trap_expected says tell resume to step
5455 (2 places), also check step_resume_break_address.
5457 * infrun.c (wait_for_inferior): Don't set
5458 prev_{pc,sp,func_{start,name}} before calling wait ().
5459 Do set them after exiting loop.

5461 (start_inferior): Initialize them.
5463 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5465 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5466 Restore old code which distinguishes between trap_expected and
5467 running_in_shell, just make the latter take any non-TRAP signal,
5470 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5472 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5473 xconfig/3b1 (CC,PINSN_CC): Define.
5475 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

5486 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5487 xm-88k.h: Define USG_UTILS.

5492 (printf_command): Add from_tty parameter.
5494 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5496 * value.h: Add optimized_out field and change lazy field to
5497 char. Add macro VALUE_OPTIMIZED_OUT.
5499 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5500 instead of stuffing things in buffers (oappend, etc).
5502 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5503 execute_command, exit both loops.
5505 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
5507 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5509 * Makefile.dist (RAPP_OBS, rapp),
5510 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5512 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5514 * valops.c (value_struct_elt), values.c (value_static_field):
5515 Change error messages to remove references to `info methods'.
