+ * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
+ size from BFD (but, FIXME, we don't yet read external nlists's and
+ convert them to internal nlists's before handling them -- we still
+ assume they have the same size and alignment.) Use SET_NAMESTRING

+ * exec.c (exec_file_command): Move dead coff-encapsulation code
+ to BFD.
+ * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

+
+Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)

+ stop at the beginning of a new line. This fixes various problems
+ with for loops, nested if-else's and switch statements.
+
+Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
+
+ * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
+ between symtabs and psymtabs become ordinary error()s.
+
+ * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
+ properly, making "end pc" correct in shared lib psymtabs.
+
+Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
+
+ * dbxread.c: Enable, but soften, const_vol_complaint.
+ (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
+ Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
+ should be file-scope, not global.
+ (read_struct_type): Remove ancient multiple-inheritance warning.
+ (read_range_type): Check base type, complain & patch if undefined.
+ * stack.c (frame_info): Demangle the function name in `info stack'.
+ (From Peter Schauer)
+
+Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
+
+ * eval.c (evaluate_subexp_for_address): Don't use
+ TYPE_POINTER_TYPE directly (it might be zero if this type has
+ never had a pointer created before); use lookup_pointer_type.
+ * symtab.c (lookup_method_type): Arguments were swapped in all
+ callers, so fix it here. I'm amazed this worked at all!
+
+Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
+
+ * c-exp.y, m2-exp.y: Define more yysymbols that happen to be

+ though only the text section's size is tracked. Mark ld_text
+ for eventual elimination as we generalize to N sections.
+
+ * infrun.c (wait_for_inferior): Don't check if the PC is in a
+ call_dummy if we were stopped by a random signal that is being
+ passed to the program. This produced wierd results when calling
+ functions in the inferior and signals (e.g. SIGALRM) were in use.
+
+Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
+
+ * infrun.c (IN_SIGTRAMP): Not parenthesized properly.

+ compilers (which may lack stddef.h).
+
+Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
+
+ * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
+ N_WARNING are the same except for the N_EXT bit, so just use their
+ values alone, rather than OR-ing them with N_EXT.
+
+Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
+
+ * mipsread.c (parse_lines): Deal with negative extended line

+
+ * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
+ global symbol conflicts.
+
+Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)

+ * language.c (_initialize_language): Fix type check and range
+ check documentation strings.
+ * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
+ language.c can use it. (Though language.c should really not be
+ handling warnings/errors the way it does, FIXME.)
+ * symtab.c (lookup_primitive_type): const lint.
+
+ Bugfix from Peter Schauer:
+ * source.c (lines_to_list): Make signed, to avoid comparison

+
+Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in (HFILES): Add minimon.h.
+ (VERSION): Roll version number to 4.0.95.
+ (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
+ New rules for building distributions. Normal distribution
+ is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
+ one level up from here; it calls make-proto-gdb.dir to build a
+ directory `proto-gdb' which is an image of the release. The old
+ `gdb.tar.Z' rule still works too.
+ * config.sub, configure: Roll in latest from ..
+
+Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
+
+ * doc/gdbint.texinfo: Reorder contents; reorganize new-host,

+
+ * mipsread.c (parse_partial_symbols): Enter the name of all

+
+Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.

+ * valprint.c (val_print_fields): Check for stub type.
+ * mipsread.c (_initialize_mipsread): Avoid using
+ builtin_type_void at initialize time.
+ (mipscoff_symfile_read): use it now.

+
+ Merge multiple-language support, and partial Modula-2 support,
+

+
+Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Add Andrew Beers' changes for Modula-2 support. His ChangeLog
+ entries are enclosed herein. Not all of these changes
+ have been merged into the master GDB sources -- check the
+ ChangeLog above here for the merge log.
+
+Mon Jun 3 17:05:45 EDT 1991
+
+ m2-exp.y Created. Tested outside of GDB for a few days. Proper
+ operators were added, C specific operators and tokens
+ removed. yylex() revamped to some extent. Still things
+ missing from the grammar, such as sets.
+ Tested for two weeks in GDB v3.5.
+
+Tue Jun 11 17:23:48 EDT 1991
+
+ m2-exp.y Added boolean constants TRUE and FALSE to the grammar
+ so they are built-in. Sort of a hack.
+
+Fri Jun 14 12:53:51 EDT 1991
+
+ m2-exp.y Added range checking for numeric constants. Any numeric
+ constant is assumed to be of builtin type INTEGER unless:
+ (1) it is octal or hexadecimal, in which case it is a
+ CARDINAL; (2) it is too big to fit into an INTEGER, in
+ which case it is a CARDINAL.
+ eval.c Added simple range checking for +, -, and * on integers.
+ Doesn't work very well for *, since 6 * 1,000,000,000 =
+ 1,705,032,704, which fails the simple test of result >=
+ first_operand, no matter in what order the operands are.
+
+Tue Jun 18 14:11:30 EDT 1991
+
+ Broke the parser into parts, one containing the C grammar and the other
+ containing code to be shared by all of the grammars.
+
+ The following files no longer exist:
+
+ expread.y
+ expread.tab.c
+
+ The following files were added:
+
+ c-exp.y (The C grammar)
+ m2-exp.y (The Modula-2 grammar)
+ parser-code.c (Code that is shared by the above grammar)
+ parser-code.h
+ parser-defs.h
+
+ Makefile.dist Changed to reflect the above dependencies. NOTE: It is
+ now necessary to use the Bison compiler compiler, since it
+ will generate function/variable prefixes other than yy.
+
+Tue Jun 18 16:47:49 EDT 1991
+
+ symtab.[ch] Added the external variable working_lang, than holds the
+ value of the current working language.
+ Added the ennumerated type language_mode, with the values
+ language_auto and language_manual, the former meaning that
+ GDB sets working_lang as needed, and the latter meaning
+ that the value of working_lang is totally under user
+ control.
+ symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
+ REAL, BOOLEAN and CHAR. Also added the type codes
+ TYPE_CODE_BOOL and TYPE_CODE_CHAR.
+ utils.c Added set_language_command and show_language_command to
+ implement the GDB support commands "set language" and
+ "show language".
+ expression.h A number of identifiers were added to the type exp_opcode
+ to facilitate Modula-2 builtin functions, integer
+ division, and array indexing.
+
+Wed Jun 19 13:25:58 EDT 1991
+
+ language.h Added the macro STRICT_TYPE, which evaluates to non-zero
+ if the language specified by working_lang requires the use
+ of strict typing of expressions. Eventually, even this
+ will be able to be changed by the user.
+ Added the macro RANGE_CHECK, which evaluates to non-zero
+ if the language specified by working_lang requires the
+ checking of a value against the domain of its type.
+ Eventually, even this will be able to be changed by the
+ user.
+ language.[ch] Predicates involving types (simple_type, ordered_type,
+ same_type, integral_type, numeric_type, character_type,
+ boolean_type, float_type) are added. These predicates are
+ based on the current value of working_lang, and are handy
+ in type-checking.
+
+Wed Jun 19 15:39:34 EDT 1991
+
+ eval.c Added the function type_array_rank which computes the rank
+ of an array type.
+ valarith.c Added the funtion value_bool, which when given a integer
+ value.h value (ie. struct value *) as an argument, it returns a
+ boolean value (ie. struct value *) true if that integer
+ is non-zero, and a boolean value false otherwise.
+ valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
+ will print out properly.
+
+Wed Jun 19 16:36:34 EDT 1991
+
+ valops.c Added the function value_capitalize, which returns it
+ value.h argument capitalized if its argument is a lowercase
+ letter, or the argument unchanged if its argument is not a
+ letter.
+ valarith.c Added the function range_check_p, which returns non-zero
+ value.h if its value argument is between the integral bounds upper
+ and lower.
+ Added the function range_check_enum_p, which makes sure
+ that its value argument is a valid member of the domain of
+ its type argument.
+ Added the function range_check_range_p, which makes sure
+ its value argument lies between the upper and lower bounds
+ of its type argument, which must be a ranged type.
+ Added the function check_array_index, which range and type
+ checks an index of an array.
+ Added the function value_multi_subscript, which computes
+ array[idx1,idx2...idxN], given a value array and an array
+ of values representing indicies.
+ values.c Changed value_from_long to work with TYPE_CODE_CHAR and
+ unpack_long to work with TYPE_CODE_BOOL and
+ TYPE_CODE_CHAR.
+
+Wed Jun 19 18:04:08 EDT 1991
+
+ symtab.c Stored pervasive types in a structure and make
+ lookup_pervasive_type() a lookup function that was based
+ on working_lang. If lookup_pervasive_type() returned
+ non-zero, then that value was returned (a fix, since
+ before it simply wouldn't return the pervasive type.)
+ language.h Added the macro CAST_IS_CONVERSION, which evaluates to
+ non-zero if the language specified by working_lang means
+ "conversion" when it says "cast".
+ valops.c Added the function value_real_cast(), which performs a
+ value.h *cast*, not a *conversion*, which is what value_cast()
+ does when it can. In particular,
+ value_cast(<float_type>,4) = 4.0, while
+ value_real_cast(<float_type>,4) = some mess.
+ eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
+ parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
+ expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
+ and MIN on integral types. *NOTE*: These are currently
+ hardcoded to work only if there are 8 bits per storage
+ unit. FIXME.
+ eval.c Made logical functions call value_bool to return a
+ properly typed boolean value, based on working_lang.
+
+Thu Jun 20 11:55:27 EDT 1991
+
+ valprint.c Types now print out in a Modula-2 fashion. This works for
+ the cases when the type is printed out step-by-step, that
+ is, it doesn't work when the name of a structured type
+ (which includes the keyword "struct", etc.) is simply
+ displayed.
+ FIXME: Perhaps this is bad. Parts of it seem to kludgey,
+ since type specifications in C and Modula-2 are very
+ different. The C printing of a type is very recursive,
+ whereas in Modula-2 it is generally very simple. C has
+ type prefixes and suffixes, which have no real analogue in
+ Modula-2. Maybe type_print() should call a language
+ specific type printer. This is also advantageous if we
+ compile GDB to exclude some of the languages. We'll just
+ leave those functions out.
+
+Thu Jun 20 16:57:10 EDT 1991
+
+ dbxread.c When reading the complete symbol table in (via
+ psymtab_to_symtab()), the number and types of function
+ arguments are added to a function type. define_symbol()
+ calls add_param_to_type() to accomplish this.
+ Assumption: when we come across a function definition
+ (N_FUN symbol with an 'f' or 'F' in the name), its
+ arguments will appear before another function definition.
+ When a function is found, a pointer to its type is placed
+ in the global in_function_type. Changes that
+ add_param_to_type() makes are to this global.
+ valprint.c The type of a function now includes (for Modula-2) the
+ types of its parameters.
+ eval.c Type checking and a check for the proper number of
+ arguments is now done for function calls. Not sure of the
+ impact this has on C++ member function yet.
+
+Thu Jun 20 19:58:48 EDT 1991
+
+ valprint.c Rewrote the type printer. Broke it into two language
+ specific parts, adding the functions type_print_m2() and
+ type_print_m2_1().
+ An unfortunate consequence is this: if you debugging a C
+ program in Modula-2 mode (why?), info types does not work
+ well with regular expressions, since the types are printed
+ out in Modula-2 terminology, but stored in C terminology.
+ language.[ch] Added the functions new_type_last(), type_keyword(), and
+ type_sep() to aid in the printing of typedefs.
+ symtab.c Made the printing of typedefs as language independent as
+ possible through calls to new_type_last(), type_keyword(),
+ and type_sep().
+
+Fri Jun 21 11:50:26 EDT 1991
+
+ dbxread.c Check all incoming ennumerated types. If it looks like
+ Modula-2's BOOLEAN type, then change the type_code of the
+ type to TYPE_CODE_BOOL so we can process it as a boolean
+ variable.
+ valprint.c Replaced some of the 0x%x with calls to sprintf and
+ hexformat() in val_print().
+ language.[ch] Added the function hex_to_string(), which converts its
+ integral argument to a hexadecimal number (format is
+ language based) and returns the result as a string.
+
+Mon Jun 24 12:25:07 EDT 1991
+
+ valprint.c Some functions call type_print_1() directly, instead of
+ value.h using type_print(), so they can specify where (column) to
+ print things. Since type_print() takes care of language
+ dependence, that needs to be called first. Added a
+ parameter depth to type_print() (so it is now like
+ type_print_1). Changed type_print to type_print_at, and
+ made type_print a macro that passes a depth argument of
+ zero.
+ symmisc.c Changed all calls to type_print_1 to calls to
+ type_print_at.
+ Makefile.dist Made it possible to build GDB for a specific set of
+ depend languages. Do this by passing a definition for the macro
+ LANGS to make. LANGS should be a string containing a
+ space-separated list of language names (ie. LANGS="c m2").
+ The default is to build all languages. Note that grammar
+ files must follow the naming convention of <lang>-exp.y.
+ gdb.lang This holds the current value of the LANGS macro. It is
+ examined every time make is called, and is updated if
+ necessary.
+ eval.c Added #ifdef _LANG_<lang> to these files.
+ expread.c Still need to add them to dbxread.c and coffread.c.
+ main.c
+ source.c
+ symtab.c
+ utils.c
+ valarith.c
+ valprint.c
+
+Mon Jun 24 16:33:11 EDT 1991
+
+ language.[ch] Added the functions hexformat_pre() and
+ hex_to_string_pre(), which take a prefix argument to
+ include in the format string. Thus, hexformat_pre("08") will
+ return "0x08x" (if the working language is language_c).
+ Made hexformat() and hex_to_string() calls to the above
+ with "" as the prefix argument.
+
+ am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
+ dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,

+ stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
+ valprint.c, vax-pinsn.c
+
+ Changed all occurences of 0x%[0-9]*l*x in printf format strings to
+ calls to hexformat() and hex_to_string(). Format strings without
+ the leading "0x" were ignored.
+
+ depend Updated to take the above into account.
+
+
+Tue Jun 25 15:27:18 EDT 1991
+
+ symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
+ and type_check_t to keep track of the current state of
+ range and type checking.
+ main.c Added the variables range_mode, range_check, type_mode,
+ and type_check to record the current state of range and
+ type checking. Added initialization code to main().
+ language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
+ the above variables.
+
+
+Tue Jun 25 17:57:08 EDT 1991
+
+ dbxread.c process_one_symbol() updates the variable (enum language)
+ source_lang based on the extension of the filename
+ contained in the N_SO sybmol that started this symtab.
+ When end_symtab() is called, the value of source_lang is
+ put into the language field.
+ stack.c select_frame() sets working_lang (and possibly type_check
+ and range_check) to the language field of the symtab
+ associated with the frame that is selected if working_mode
+ is language_auto. If working_mode is language_manual, a
+ warning is printed and working_lang is not set.
+ language.c Added the function set_type_range(), which sets the value of
+ type_check and range_check (if their modes call for
+ automatic setting) based on the current value of
+ working_lang. A non-zero argument will cause the current
+ settings to be output.
+
+
+Wed Jun 26 14:51:40 EDT 1991
+
+ eval.c Added range checks on assignment.
+ m2-exp.y Added the grammar for sets to the language. Currently,
+ these do not do anything except print an error message.
+
+Wed Jun 26 17:01:04 EDT 1991
+
+ m2-exp.y Added the ability for parse_number() to parse negative
+ numbers. A global flag is set upon encountering a unary
+ minus. This was done to make, for example, 1 parse as a
+ CARDINAL, and not as an integer, per Wirth's examples in
+ Programming in Modula-2 ed.4.
+ valprint.c Added support for "set radix 2" by then setting
+ output_format to 't'.
+ eval.c Implemented range checking on subrange types. Added calls
+ to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
+ Implemented MIN and MAX for ennumerated types. The
+ minimum value of an ennumerated type is defined by Wirth
+ as the first identifier, and the maximum as the last.
+ m2-exp.y Made octal numbers ending with "B" be characters and those
+ ending with "C" be numbers, per Wirth's book. (p. 34)
+
+Thu Jun 27 14:11:52 EDT 1991
+
+ stack.c select_frame() now only sets working_lang, it does not
+ notify the user. If working_mode is language_manual, then
+ a warning is issued once.
+ main.c At the end of each call to execute_command(), working_lang
+ is checked against the local static (enum language)
+ current. If they differ and working_mode is
+ language_auto, the new settings of language, type and
+ range checking are printed out.
+ stack.c Modified frame_info() to include the language of the
+ current frame in the output of "info frame".
+ language.[ch] Added the function language_str() which returns the name
+ of the current language.
+
+Fri Jun 28 15:33:14 EDT 1991
+
+ m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
+ the language. INCL and DECL currently cause an error,
+ since sets are not implemented yet. INC and DEC are
+ implemented as PREINCREMENT/PREDECREMENT with one
+ argument, and as ASSIGN_MODIFY with two arguments.
+ eval.c Added type checking to the above cases.
+ value.h Added not_lval_constant to the lval_type ennumerated type.
+ not_lval_constant means that the value is a constant
+ value; that is 3 or 'a' or TRUE, not as in a constant
+ identifier. This is used to help coerce numbers such as 3
+ to either signed or unsigned numbers.
+ valops.c Added the function value_coerce_constants() which coerces
+ constant integers as following: if one is a constant and
+ the other is not, the constant's type is set to the type
+ of the other argument. If both are constants and one is
+ signed, the other is converted to a signed constant.
+
+Sat Jun 29 17:26:29 EDT 1991
+
+ valarith.c Added a better range checker. It now checks range
+ (successfully) on integral operations [+-] (signed and
+ unsigned) for any C sized type. Still does not work well
+ for multiplication.)
+ int_in_size() returns an integer that is coerced to fit into
+ specified number of bytes.
+
+Mon Jul 1 13:04:14 EDT 1991
+
+ language.[ch] Added the function binop_result_type(), which returns the
+ builtin (struct type *) type that would be the result of a
+ binop on the two values V1 and V2.
+
+Wed Jul 3 19:22:53 EDT 1991
+
+ source.c Extended source_info() to include the source language in
+ the output from "info source".
+
+Fri Jul 5 13:48:52 EDT 1991
+
+ utils.c Moved the support functions for the GDB set/show commands
+ dealing with language into language.c.
+ language.c Added the function language_info(), which displays info
+ about the current working language, type and range check
+ settings. Called via the GDB command "info language".
+ Added an initialization routine _initialize_language(),
+ that sets defaults for the language, type and range
+ variables and sets up the new GDB commands.
+ main.c Language setup moved to language.c.
+ depend Rebuilt.
+
+Mon Jul 8 10:10:22 EDT 1991
+
+ valarith.c Debugged the range checker for arithmetic. Still does not
+ work for multiplication very well.
+
+Mon Jul 8 12:40:37 EDT 1991
+
+ language.[ch] Added the function value_true() which returns non-zero if
+ its argument represents a boolean true value.
+ breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
+ check the truth of an expression.
+
+Thu Jul 11 12:51:34 EDT 1991
+
+ language.[ch] Added the predicate structured_type(), which returns
+ non-zero if the argument is a structured type.
+ Added the predicate pointer_type(), which returns non-zero
+ if the argument is a pointer type.
+ eval.c Added the ability to do addition and substraction on
+ pointers and integers. This case simply bypasses the
+ type checker.
+
+Thu Jul 11 14:41:42 EDT 1991
+
+ include/stab.def
+ Added the symbol N_DEFD (0x4a) which is a definition
+ module dependency that is used by the GNU Modula-2
+ compiler and the linker. It is not important to GDB,
+ except that [dbx|coff|mips]read.c should ignore these
+ symbols.
+
+Fri Jul 12 16:07:00 EDT 1991
+
+ valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
+ 0 in val_print(). Also added statements to the else part
+ to coerce type (argument to val_print) to a pointer type
+ if it is an "array of unspecified length".
+ valops.c Added the function value_m2_string(), which returns a
+ (value) value which is a constant string, whose type is
+ (ARRAY [0..n] OF CHAR). The length field of the type
+ structure is set to zero, so it will be interpreted as an
+ "array of unspecified length".
+ stack.c Moved the language/frame mismatch check to
+ main.c:execute_command().
+ main.c The working language is recorded each time
+ execute_command() is executed. If working lang has
+ changed during its execution, then the new
+ language/type/range info is printed out for the user. If
+ the working language does not match the language of the
+ frame, a warning is issued.
+
+Sat Jul 13 16:16:39 EDT 1991
+
+ eval.c Moved all the type-checking stuff for operators to
+ language.[ch] language.c. This is so we can keep language-specific
+ stuff (like for what type operators are defined) in
+ language.c.
+ language.[ch] Added the function binop_type_check(), which checks to see
+ if its two (value) arguments are type-compatible with its
+ opcode argument. The opcode should represent an operation
+ involving an operator. Also added the macro function
+ unop_type_check, which calls binop_type_check with a
+ NULL second argument.
+ expprint.c Added Modula-2 operators to the op_print_tab, so info
+ expression.h break works correctly. Also added "op_string", which
+ returns the string corresponding to the (enum exp_opcode)
+ opcode that is its argument.
+
+
+Sat Jul 13 18:26:18 EDT 1991
+
+ coffread.c Added code to record the type of function arguments with
+ each paricular function. Code is very similar to that
+ added to dbxread.c.
+ dbxread.c Moved add_param_to_type() to symtab.c
+ symtab.[ch] Added function add_param_to_type() from dbxread.c
+
+ *** NOTE: The above additions have not been tested.
+
+Mon Jul 15 12:50:47 EDT 1991
+
+ langauge.[ch] Added the functions type_error and range_error, which work
+ like error() except if the type/range mode is set to
+ *_mode_warn, then they do not do a return_to_top_level(),
+ but merely print a warning.
+ Also changed [set|show]_[type|range]_command() to support
+ the new "warn" feature.
+
+Thu Jul 18 17:50:54 EDT 1991
+
+ mipsread.c Added code to record the type of function arguments with
+ each particular function. Code is very similar to that
+ added to dbxread.c.
+
+ *** NOTE: The above additions have not been tested.
+
+Fri Jul 19 11:19:10 EDT 1991
+
+ defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
+ UMIN_OF_SIZE, which when given a size of a numeric type,
+ return the maximum and minimum value it can hold. UMAX...
+ and UMIN... return the result for unsigned types.
+ symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
+ struct types. They call above macros.
+ dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
+ avoid a name conlict with the above.
+ c-exp.y Added range checking on numeric constants in
+ parse_number() for completeness.
+ valarith.c Made binop_user_defined_p() and unop_user_defined_p()
+ return 0 if working_lang is not language_c.
+
+Thu Aug 8 14:17:22 EDT 1991
+
+ main.c
+ printcmd.c
+ breakpoint.c Documentation strings of some commands changed to
+ eliminate the references to the C language where
+ appropriate.
+
+Tue Aug 13 15:48:03 EDT 1991
+
+ m2-exp.y Added qualified identifiers to the grammar. The semantics
+ are slightly different from those of the GDB operator ::
+ c-exp.y
+ m2-exp.y Added a rule to each grammar of the form: start ::= exp |
+ type_exp, where type_exp is any valid type expression.
+ expression.h
+ eval.c Added the opcode OP_TYPE, and an error case in eval.c.
+ printcmd.c Modified ptype_command() so it actually parses the input
+ (necessary for type expressions with scope qualifiers).
+ Added the function ptype_eval() which expects an
+ expression composed of one OP_TYPE element.
+ *.[ch] Replaced all occurences of parse_c_expression with
+ parse_expression
+ *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1

+ * valops.c (call_function_by_hand): declare text_end.
+
+ * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of

+ because machines that do this will also have to know to
+ set NEED_TEXT_START_END. Besides, it was a redundant way to
+ say the same thing.
+ * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate

+ * munch: Cope with RT/PC putting fns in data segment.
+ Restore ability to override `nm' by specifying MUNCH_NM.
+ * xconfig/rtbsd, xconfig/ultra3: New host systems.
+ * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
+ and remote-adapt. Remove encapsulated coff #define's (the
+ support should go in BFD, and gdb shouldn't know or care).
+ * tconfig/a29k-kern: Same, but for remote kernel debugging.
+ * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
+ * tm-29k.h: Update BADMAG (though it should go away).
+ Allow the register definitions to be overridden in another
+ tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
+ RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
+ DUMMY_SAVE_GR96, for handling kernel calling conventions
+ that use GR64+ rather than GR96+.
+ * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
+ remote debugging of Ultra3 kernel. Includes tm-29k.h and
+ overrides various things.
+
+ * remote-mm.c (mm_attach, mm_wait): Handle attach like
+ child_attach does, making a clean stop in the newly attached
+ program.
+ * remote-eb.c: Lint.
+
+ * coffread.c: Make coffread independent of any particular
+ variant of COFF. Avoid #include-ing any particular one except
+ internalcoff.h. BFD now passes key values for symbol reading
+ as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
+ and the symbol masks and shifts); use them.
+ Remove obsolete end_of_text_addr.
+
+ * exec.c: Remove unused include files.
+
+Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)

+ * utils.c (error): if error_pre_print is set, print the string
+ first.
+ * main.c (main, print_gnu_advertisement, print_gdb_version):
+ Reformat legalese so it always prints, but acts as an "I'm here"
+ message while symbols are being read. If any errors occur,
+ print a few newlines to set off the message and start it at the
+ left margin. Remove mention of "help" command, and don't yak
+ about symbol reading.
+ (catch_errors): Error string is now printed first in case of
+ error, not last.
+ * command.c (undef_cmd_error, lookup_cmd): On undefined command,
+ suggest the "help" command.
+
+ * Makefile.in (VERSION): Set to 4.0.2.
+
+Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * .gdbinit: Remove useless "rr" command. Set complaints
+ to 1 for people debugging gdb.
+
+ * breakpoint.c, remote-vx.c: Reword strings printed by
+ catch_errors callers.
+
+Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * WHATS.NEW: "history write -> history save". Doc "write on/off".
+
+ Fix some infrastructure to be able to cope with host and target
+ machines with different sized basic types (ints, ptrs, etc).
+
+ * values.c (value_from_longest): Rename from value_from_long.
+ Handle pointer types as well as integers, so that targets with
+ different pointer sizes from the host can be accomodated.
+ * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
+ valarith.c, valops.c, valprint.c, value.h, values.c: Rename
+ uses of value_from_long to value_from_longest.
+ * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
+ the correct pointer type to value_from_long{est}.
+
+ * doc/gdb.texinfo ($_, $__): Describe types of these variables.
+
+ * remote-vx.c: Remove obsolete code for calling functions via
+ vxworks kludge interface (it referenced value_from_long).
+
+ * valops.c (value_string): Find malloc with lookup_misc_func, not
+ raw search.
+
+Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Make writing to files work properly. (Fixes to BFD are also needed.)
+
+ * core.c (core_open): Open file ourselves, read or r/w, depending on
+ write_files. Use bfd_fdopenr.
+ * gdbcore.h (write_files): New variable.
+ * exec.c (write_files): Define variable, add set&show for it.
+ (exec_file_command): Use write_files to open for read or r/write.
+
+ Make shared library reading happen automatically. These changes
+
+ * inferior.h (stop_soon_quietly): Add to exported variables.
+ * infrun.c (child_create_inferior): call solib hook, if defined.
+ (child_attach): call solib hook, if defined.
+ * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
+ (find_solib): Use lookup_misc_func rather than hand-rolled.
+ (symbol_add_stub): New stub for catch_errors.
+ (solib_add): Avoid output if !from_tty. Catch errors rather
+ than just calling symbol_file_add and bombing.
+ (solib_create_inferior_hook): Interface with the target process
+ to let it read and alloc shared libs, then figure out what it did.
+
+ * core.c (validate_files): Fix typo, soften warning.
+
+ * utils.c (fputs_demangled): Avoid duplicate printing if
+
+ * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
+
+ * main.c (catch_errors): Change argument to a char * from an int,
+ since a char * can point to a struct full of glop, but an int
+ is not guaranteed to be able to hold a pointer.
+ * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
+ breakpoint_re_set_one, breakpoint_re_set): Adapt.
+ * core.c (core_open, solib_add_stub): Adapt.
+ * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
+
+Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
+ by adding .NOEXPORT target.
+
+Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * GDB-4.0 release!
+ * Update README.
+ * Makefile.in (VERSION): Roll to 4.0.
+ (gdb.tar.Z): Make refcard.ps as well, for shipment.
+
+Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
+ more on printsyms.
+
+ * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
+ "gdb-all.texinfo"
+
+ * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
+
+ * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
+ reflect above name change
+
+ * WHATS.NEW: correct pointer to refcard.
+
+ * doc/gdb.texinfo: update New Features, Installing
+
+ * doc/gdbint.texinfo: add short description of configure +template
+
+Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
+
+Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
+ tar file, add dependencies for referenced doc files.
+
+Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
+
+ * coffread.c, symfile.c, stack.c: saberized.
+
+Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/refcard.tex: permuted Essential Commands sec
+

+ default set complaints 0
+ info all-registers

+
+Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
+
+ * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
+ cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
+ breakpoint.c, main.c: lint.
+
+Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Install new configuration scheme for GDB and friends.
+
+ * config.sub: Translate ordinary names to three-part names.
+ * configure: Use three-part names internally.
+ * configure.in: Translate three-part names to filenames.
+
+ * README, WHATS.NEW: Update for gdb-4.0.
+ * Makefile.in: Roll VERSION to 3.99.
+
+Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
+ * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
+ tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
+ to single structures rather than arrays; when passing
+ their address, use &. This avoids trouble with bdead compilers.
+ * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
+ instead. This avoids portability headaches.
+ * mips-tdep.c (mips_do_registers_info): Only print FP regs if
+ asked to.
+ * source.c (open_source_file): Avoid ANSI const bdeath by
+ skipping declaration and then casting result value.
+ * tm-hp300bsd.h: Clarify comment.
+ * utils.c (strstr): Result is const char *; ANSI bdeath.
+ * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
+ since system include file defines it differently from "defs.h",
+ though the two are equivalent for our purposes.
+ * tconfig/hp300bsd: Add m68k-tdep.o.
+
+Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tconfig/sun*4: Remove warnings about system assembler.
+
+Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * mcheck.c: Avoid warning about undeclared abort fn.
+ * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
+ it causes recursive calls to error() when used in cleanups.
+ To do so requires that we make it a function, so we do.
+ * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
+ * utils.c (do_cleanups): Remove the current cleanup from the
+ chain *before* calling it, in case error() is called from it.
+ The result won't be pretty, but won't be an infinite loop either.
+
+Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * dbxread.c (read_struct_type): Grok anon structs for C++.
+ (vb_name, vptr_name): Null terminate these strings.
+
+Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Minor bug fixes from BSD Net2 gdb:
+
+ * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
+ returns 0, there is no previous frame.
+ * breakpoint.c (commands_command): If !from_tty, don't call
+ input_from_terminal_p().
+ * dbxread.c (record_misc_function): Speed up slightly.
+ (compare_psymbols): Ditto.
+ * infcmd.c (do_registers_info): Take a second argument to
+ determine whether to print float registers. "info registers"
+ does not do so anymore. "info all-registers" does, now.
+ * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
+ arg and ignore it.
+ * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
+ * inflow.c (initialize_inflow): Set tflags_ours correctly.
+
+ Other fixes:
+
+ * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
+ executing_breakpoint_commands if we are interrupted by error.
+ * coffread.c (init_lineno): Avoid problem with zero-sized linetab
+ * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
+ catch_errors() so we can setup the frame regardless of whether
+ the shared libs work.
+ * ieee-float.c (double_to_ieee_extended): Get exponent from
+ right place in little-endian systems. From John Carey.
+
+Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * main.c: Remove unused terminating_signals and catch_termination().
+ (long_options): Terminate with a zero element.
+ (gdb_readline): Make call-compatible with readline.
+ (init_signals): Improve comments re vfork vs. signal.
+
+ * utils.c (prompt_for_continue): Use new gdb_readline().
+ If we prompt for continuation, we don't let CR repeat the previous
+ command, once we get back to a prompt. It's too easy to keep
+ hitting CR, expecting "--more--" prompts, and have some long
+ command start repeating on you.
+
+Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * blockframe.c (frameless_look_for_prologue): Speed up by
+ calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
+ * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
+ Define two variants, one faster.
+ * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
+ and return zero, rather than giving an error.
+ (setup_arbitrary_frame): Initialize the PC in the new frame.
+ (skip_prologue): Add a second arg saying whether we're just
+ checking for a frameless function or not.
+
+ * core.c (core_open, core_close, core_xfer_memory): Move
+ section table pointers and bfd* into the target_ops.
+ (core_open): Allow errors in shared lib reading, etc.
+ (core_files_info): Describe shared library sections.
+
+ * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
+ exec_files_info, set_section_command): Move section table
+ pointers and bfd* into the target_ops.
+ (add_to_section_table): Add BFD to section table.
+
+ * target.c (target_xfer_memory, target_info): Pass target to
+ xfer_memory and target_info functions.
+ * target.h: ''
+
+ * gdbcore.h: Move struct section_table.
+ * target.h: New home of struct section_table.
+
+ * solib.c (solib_add): New argument is the target_ops whose
+ section list is to be added to, if any. Reallocate the
+ sections in that target to add any that come from shared libs.
+ (throughout) so_sections renamed to sections.
+ (solib_xfer_memory): Deleted.
+ * tm-sunos.h (SOLIB_ADD): Add target argument.
+ (SOLIB_XFER_MEMORY): Delete.
+
+ * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
+ from target_ops. It's the same on all targets. Add two section
+ pointers to target_ops.
+
+ * stack.c (find_relative_frame): Dump ancient algorithm for
+ "down", just use handy "next" pointers.
+ (frame_command): Don't error if there is no stack; let user
+ set one.
+
+ * inflow.c (new_tty_prefork, new_tty): New prefork routine
+ modifies static state in the parent process; new_tty itself
+ runs in the child and modifies the child's file descriptors
+ to match the saved static state.
+ * infrun.c (child_create_inferior): Call new_tty_prefork,
+ fork, then new_tty.
+
+ * infptrace.c (child_xfer_memory): Add ignored target arg.
+ * remote-eb.c (eb_xfer_inferior_memory): ''
+ * remote-nindy.c (nindy_xfer_inferior_memory): ''
+ * remote-vx.c (vx_xfer_memory): ''
+ * remote.c (remote_xfer_memory): ''. Rename from
+ remote_xfer_inferior_memory.
+
+ * main.c (main): Only try to attach "corefile" argument if
+ it starts with a digit.
+
+ * symfile.c (symbol_reloading): New "set/show" variable.
+ (symbol_file_add): Shorten message about symbol reading.
+ (add_symbol_file_command): Merge with add_syms_addr_command,
+ since this should work on all targets now.
+ (stop_whining): Default to zero, to shut up complaints
+ about bad symbol tables on many systems.
+ (free_named_symtabs): Just exit unless symbol_reloading.
+
+ * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
+ and add comment explaining shared library screw.
+
+ * source.c: #if defined => #ifdef.
+
+Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * doc/gdbint.texinfo: Improve doc on porting to new OS's.
+
+Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/rdl-apps.texinfo: provide default readline-appendix finder
+ (doc/Makefile knows how to make one for local config)
+
+ * Makefile.in: use doc/Makefile for doc targets
+
+ * doc/Makefile: GDB documentation now has its own Makefile
+ doc/refcard.tex: renamed from "gdbrc.tex"
+ doc/.Sanitize: add Makefile; recognize renamed refcard.tex
+ doc/gdbint.texinfo: add markup in "Cleanups" chapter
+
+
+Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * values.c (baseclass_addr): When reading target memory, use the
+ length of the basetype, not the upper type. We've only malloc'd
+ enough space for the basetype, leading to errors in free().
+
+ * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
+ ends up as a function specially, since we know the actual type of
+ the pointed-to address. This (somewhat) fixes display of
+ expressions that include misc_function_vector names. Try `cond 1
+ !strcmp("a","b")' then `i b'.
+
+ * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
+ The child can be proceeded from inside wait_for_inferior in
+ evaluating breakpoint conditions, and DO_DEFERRED_STORES was
+ getting skipped in that case.
+
+ * expprint.c (print_subexp): Use filtered output, since the
+ subroutines we call use it, otherwise the output is horribly
+ mangled, since output of wrappable stuff comes out late.
+
+ * Makefile.in: Bump VERSION to 3.98.1
+
+ * infrun.c (child_create_process): Use execlp to find the
+ shell to exec our target program. This requires some fiddling
+ with `environ' since there is no execlpe().
+
+Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
+ Minor rearrangement of refcard permits two new make targets--
+ gdbrc.dvi DVI output for refcard, using CM fonts
+ gdbrc.ps PostScript refcard, using PS fonts
+
+Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * GDB-3.98 release.
+
+ * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
+ * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
+
+Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo: last changes for release.
+ Minor typo and formatting fixes; incorporated most fixes remaining from
+ filed mail commenting on earlier drafts.
+
+ Added warnings: pipes don't work in run command;
+ conditions are converse of assertions;
+ step over fn without debug info goes to next fn;
+ vars may have "wrong" values near fn entrance, exit
+
+ Added example from Kingston on printing repeated nonadjacent values
+
+ Added explicit mention that in Emacs gdb mode C-c and C-z are like
+ shell mode for signals
+
+ Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
+ doesn't sound so much like its parent "Stopping and Continuing"; also
+ moved entries on continue to top of section, so they don't get lost.
+
+ Improved installation directions in appendix, added manual formatting
+ instructions
+
+Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * configure.in: Remove xm.h and tm.h even if we aren't linking
+ new ones, so "./configure sun4; ./configure none" does the right
+ thing. Assume that alldeps.mak and depend are already built in
+ srcdir, and avoid running "make" (particularly "make depend",
+ which involves "gcc") from inside configure. Build Makefile
+ directly rather than building Makefile.conf first.
+ * configure: Regenerate with above changes.
+ * Makefile.in: Use $(BISON) to find bison. Roll VERSION
+ to 3.98. Revise gdb.tar.Z procedure to produce a file
+ called gdb-$(VERSION).tar.Z but which unpacks into a
+ directory called "gdb". Move non-source files out of
+ $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
+ (depend): Don't try to do "gcc expread.y".
+ (expread.o): Update dependencies by hand.
+
+Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo:
+ Fixed a variety of small typos that prevented info from formatting
+ cleanly; altered too-long heading for GPL Appendix, as discussed
+ w/RMS; Changed date on cover to July 91.
+
+Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo:
+ (1) Applied some fixes due to comments from Larry Breed (easier ones
+ through chapsec 5.2)
+ (2) Eliminated use of @footnote---had my doubts about it anyways, and
+ it's broken in latest texinfo
+ (3) Introduced *some* use of [] for optional arguments, where
+ explanation is not simpler by listing cmd w arg and cmd w/out arg
+ separately. Still not using @deffn.
+ (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
+ couple of headings are too long. Need patches to texinfo or revision
+ to GPL-2.
+
+ * Partial update to README (which still needs work for this
+ release!): (1) use of configure corrected for new script,
+ (2) "make gdb.dvi" and "make gdb.info" mentioned.
+
+Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symtab.c (lookup_symbol): Don't complain right off about
+ no debug symbols; use the misc function vector first.
+ (list_symbols): Use misc function vector to find symbols
+ that don't have debug info, and print them.
+ (find_pc_symtab): Temporarily avoid fatal() when psymtab
+ PC range doesn't match symtab PC range, as it does on the
+ MIPS because our symtab reading isn't perfect.
+
+ * dbxread.c (dbx_symfile_read): Make warning about
+ "no debug symbols" slightly nicer.
+
+ * source.c (select_source_symtab): If "main" symbol exists,
+ but decode_line_spec can't find line info, don't just return
+ a zero; try other source symtabs or give an error.
+
+ * mipsread.c (parse_partial_symbols): Sort the psymtabs by
+ their low addresses first, then rip through fixing high addrs.
+
+ * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
+ (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
+
+Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * Minor, mostly mechanical, cleanup of doc subdir for clean
+ makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
+ and gdb.info (post- texinfo2 makeinfo) generated for distribution.
+
+Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Mostly MIPS and general symbol-reading fixups.
+
+ * doc/gdbint.texinfo: Add documentation on symbol-reading
+ interface.
+
+ * mipsread.c: Remove kludges around #include "ecoff.h".
+ Remove redefinitions of a_magic, etc, no longer used.
+ (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
+ Fix global overview comments to match symfile.c protocol.
+ (mipscoff_new_init): Eliminate cur_hdr if we have one.
+ (mipscoff_symfile_read): Eliminate unused code. Avoid
+ sorting all the symtabs, when all we have read here is psymtabs.
+ The symtabs are sorted as they are created anyway. Tell
+ condense_misc_bunches whether we're mainline.
+ (psymtab_to_symtab_1): Pass filename when recursing, to make
+ stack trace more informative.
+ (parse_partial_symbols): Assume cur_hdr as argument.
+ (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
+ Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
+ the TYPE_NAME of char *, since that's done in symfile.c.
+ (free_numargs, parse_symbol, add_symbol, add_block,
+ shrink_linetable): Declare these fns void.
+ (upgrade_type): Convert tree of if's to switch. Clean up
+ bogus "off == 0" handling with a complaint. Avoid setting
+ field bitpos and bitsize of array with lower and upper bounds.
+ Check specified bitsize of elements against their actual type's
+ bitsize, and complain if different. Complain about unknown
+ type qualifiers.
+ (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
+ (psymtab_to_symtab_1): Print names of subsidiary files that
+ are being read in. FIXME, we read far too many files. This code
+ is not the problem, the problem is in parse_fdr where the psymtabs
+ are set up.
+ (cross_ref): Result should indicate that we used one aux entry
+ normally, or two if we encountered a "next" entry. This used
+ to leave the caller pointing at the wrong aux entry.
+ (add_symbol): If overflowed cur_block, reallocate it larger,
+ chase all pointers to it, and complain(), rather than clobber memory.
+ (shrink_block): Use xrealloc rather than xmalloc-and-copy.
+ (new_field): Only allocate one field initially, not two.
+ Pull ++ out of macro argument. Simplify.
+ (_initialize_mipsread): Avoid initialization of importd
+ global_psymbols and static_psymbols.
+
+ * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
+ to properly set pst->symtab; avoid searching for it.
+ (symfile_fns): Improve comments, add a FIXME.
+ * dbxread.c: Update comments to reflect symfile protocol.
+ (read_ofile_symtab, end_symtab): Return the symtab.
+ (psymtab_to_symtab_1): Set pst->symtab.
+
+ * coffread.c (coff_symfile_read): tell condense_misc_bunches
+ whether we're mainline.
+
+ * symfile.h (sym_fns): Remove unused sym_discard member.
+ * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
+
+ * mtrace.c (mtrace): Take effect if mallwatch is set, even if
+ the environment variable is not.
+ * infcmd.c (finish_command): Use filtered printfs.
+ * cplus-dem.c: Add struct tags to a few unnamed structs.
+ * valops.c (value_coerce_array): Improve comments.
+ * valprint.c (type_print_varspec_suffix): Print array size only
+ if greater than zero.
+ * m88k-tdep.c: Shift some lines left by one space, that had
+ apparently been trashed at some point.
+ * TODO: More things to do, a few got done.
+
+Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
+ (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
+ comments.
+ * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
+ * expread.y, findvar.c, symmisc.c: Ditto.
+ * printcmd.c (address_info): Update printed forms of LOC_
+ symbols. Elim LOC_EXTERNAL.
+ (print_frame_args): Keep track of param stack offsets before
+ re-looking up to find the local register param is kept in.
+
+ * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
+ Further integration of mipsread into gdb. Eliminate unused
+ routines, duplicate declarations. Handle static symbols in
+ psymtabs as well as external symbols. When reading symtabs,
+ insert symbols into the correct block (global, static, or a local
+ block).
+ (read_mips_symtab, parse_partial_symbols): Don't pass useless
+ "incremental" arg.
+ (mipscoff_symfile_read): Don't call select_source_symtab.
+ (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
+ rather than SYMBOL_VALUE.
+ (parse_external): Comment clobbering of top_stack.
+ (parse_partial_symbols): Update comments. Allocate and parse
+ static symbols as well as external symbols. FIXME, enum values
+ are not handled in this pass, but should be. Inline new_psymbol.
+ Use SYMBOL_VALUE_ADDRESS.
+ (psymtab_to_symtab_1): Read symbols into global static block
+ by default (until enter some function's local block context).
+ (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
+ (destroy_all_symtabs, new_psymbol): Eliminate, unused.
+
+ * source.c (select_source_symtab): Select a source symtab
+ from either the symtabs or, failing that, the psymtabs.
+ (list_command): Update error message.
+ (forward_search_command, reverse_search_command): Use getc, not
+ fgetc, for speed. FIXME, add comment about buffers that die if
+ overrun by long line.
+
+ * values.c (unpack_field_as_long, modify_field): Avoid shifting
+ by an entire word, which is not portable, if we have a 32-bit
+ field. (Code in dbxread.c already turns such bitfields, if
+ aligned, into ordinary ints, but fixing this will help for other
+ symbol formats and for future changes.)
+ * core.c (core_open): Handle ANSI const brain death.
+ * utils.c (vprintf): Fix varargs typo.

+
+ * findvar.c (find_var_value): Handle &function better.
+ * TODO: Document work needed on &fn and &array.
+ * printcmd.c (print_address_symbolic): New arg is the prefix
+ to print if a name is printed.
+ (print_address_demangle): Honor "set print address" now.
+ Use new arg above to improve spacing of output.
+ * valprint.c (val_print): When printing function pointers,
+ print symbolic form too.
+ * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
