181 been read in, particularly for VxWorks.
183 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
184 to the main file, as well as to include files. Also, put global
185 functions into the global psymtab, to make "i fun" work.

187 new psymtab for it has been read.
188 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
189 a file, once a new symtab has been read for it.
190 * mipsread.c: FIXME. We need to do the same for MIPS, but it
191 looks harder to determine the top-level block before it's been
192 queued to the psymtab list.
194 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
195 If we have wiped out any old symbol tables, clean up at end of
197 (symbol_file_command): Don't reference symfile_fns if it's zero.
199 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
200 defines for the blocks of a blockvector that contain global and
201 file-static symbols and the first of the smaller scope contours.
202 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
203 decode_line_1, make_symbol_completion_list): Use the above.
204 * coffread.c (end_symtab, patch_opaque_types): Ditto.

216 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
218 * m68k-stub.c: Remote stub for 680x0's, created from
219 rem-m68k.shar (which is removed).
220 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
221 Remove RCS log stuff now that we use CVS and it blows our diffs.
223 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
225 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

239 been read in, particularly for VxWorks.
241 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
242 to the main file, as well as to include files. Also, put global
243 functions into the global psymtab, to make "i fun" work.
244 (end_psymtab): Free named symtabs and psymtabs for a file, once a
245 new psymtab for it has been read.
246 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
247 a file, once a new symtab has been read for it.
248 * mipsread.c: FIXME. We need to do the same for MIPS, but it
249 looks harder to determine the top-level block before it's been
250 queued to the psymtab list.
252 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
253 If we have wiped out any old symbol tables, clean up at end of
255 (symbol_file_command): Don't reference symfile_fns if it's zero.
257 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
258 defines for the blocks of a blockvector that contain global and
259 file-static symbols and the first of the smaller scope contours.
260 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
261 decode_line_1, make_symbol_completion_list): Use the above.

277 rem-m68k.shar (which is removed).
278 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
279 Remove RCS log stuff now that we use CVS and it blows our diffs.
281 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
283 * symmisc.c (free_named_symtab): Make it work, in its current
284 kludgy fashion. Change result to indicate if we blew away bkpts.
285 * dbxread.c (end_symtab): Accumulate result from
286 free_named_symtab and print warning if we blew user's state.
287 * symfile.h: free_named_symtab now returns an int.
289 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
291 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
292 is the first symbol read, even if not mainline.
293 (dbx_psymtab_to_symtab): symfile might be zero, cope.
294 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
295 (set_section_command): New command ("section xxx yyy" -- should
296 be renamed to "set section xxx yyy" FIXME) which sets the
297 base address of a section of the exec file, overriding the
298 virtual address that BFD reports.
300 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
302 * exec.c: Add add_syms_addr_command to exec_ops, so you can
303 load symbols at any address while examining an exec file.
305 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
307 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
308 for printing the float info is host-dependent, not
309 target-dependent. FIXME.
310 * i386-pinsn.c: Move #includes to top, remove useless ones.
311 * i386-tdep.c: Don't bother including <.../reg.h> since we
312 don't use it (and it doesn't exist on host systems).
314 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
315 Convert negative numbers properly.
316 (ieee_test): Make numbers really random; fix format arg.
318 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
319 * core.c (core_detach): Unpush core_ops, which might not be on
320 top. We used to just pop the top, which broke things. Don't
321 need dont_repeat() any more.
322 (core_file_command): Psst! Don't repeat it.
323 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
324 * expprint.c (print_subexp): Avoid switch fallthru on
325 BINOP_ASSIGN_MODIFY, so we can print += and such.
327 * inflow.c (kill_command): After killing inferior, print our
328 current frame in the core file, if we have one.
329 (generic_mourn_inferior): When inferior dies, either select
330 the current frame (in the new target, e.g. core file), or
331 set both the current and selected frames to NULL.
333 Changes from Peter Schauer.
335 * infptrace.c: Avoid <sys/ptrace.h> on USG.
337 * Make all file names fit in 14 characters (sigh and damn!):
338 mv hp300hpux-xdep.c hp300ux-xdep.c
339 mv symmetry-xdep.c symm-xdep.c
340 mv symmetry-tdep.c symm-tdep.c
341 mv convex-opcode.h convx-opcode.h
342 mv tm-vxworks960.h tm-vx960.h
343 mv tm-vxworks68.h tm-vx68.h
344 mv Makefile.srcdir Makefile.sdir
345 mv gdb-int.texinfo gdbint.texinfo
346 mv remote-sa.m68k.shar rem-m68k.shar
347 mv remote-multi.shar rem-multi.shar
348 * Makefile.dist, README, config.gdb, convex-pinsn.c,
349 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
350 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
353 * command.c (user_info_1, user_info): New command for listing
354 the user-defined commands.
356 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
358 * dbxread.c (really_free_pendings): Clear file_symbols
359 and global_symbols after freeing them; otherwise, running
360 this function twice (if it appears twice on the cleanup
361 chain), we try to free things twice.
363 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
364 based on text_addr (the address of text in core), not on addr (the
365 offset between text in the .o file and in core). This change
366 is from Peter Schauer.
368 * main.c: Define ALL_CLEANUPS as a cast of zero.
369 (return_to_top_level): Use it.
370 (main): Do all cleanups after each command run as part
371 of the gdb startup sequence. Also do all cleanups before
372 entering the command loop, and every time we exit the command
373 loop and reenter. Before, the cleanups from the startup sequence
374 were being left undone until the first error!
375 (command_loop): Rename do_nothing cleanup to command_loop_marker
376 so we can see it easily when examining the cleanup chain.
377 (init_signals): Add another do_nothing for signal handling.
378 (quit_command): Only try to kill target if it has execution.
379 Problems in the target stack got us into a state where
380 inferior_pid was nonzero but none of the targets had execution.
381 In this state you couldn't exit gdb.
383 * dbxread.c: Two changes from Peter Schauer.
384 (echo_command): Fflush output after an echo command.
385 (show_history): Pass all args to cmd_show_list.
387 * utils.c (init_malloc): Call mtrace to turn on tracing
388 if the environment variable MALLOC_TRACE is set to a file name.
389 * mtrace.c: Add source file which provides a log of every malloc,
390 free, and realloc to a trace file.
391 * mtrace.awk: Add source file which analyzes the trace file.
392 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
393 (VERSION): Roll to 3.94.3.
395 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
396 (check_duplicates): Don't bother with watchpoints.
397 (set_raw_breakpoint): Comment about danger of this routine.
398 (watch_command): Parse and eval all args before calling
401 * solib.c (find_solib): Avoid error in referencing memory to
402 see if any more shared libraries have been added. This is
403 particularly useful if the target has terminated. Bug reported
407 in bringing up 3.94.2 on the Sun-3.
409 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
410 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
411 expression (in scope) before reenabling watchpoint.
412 * signame.c (init_sigs): Add missing declaration of i, fix
413 sys_siglist declaration.
414 * source.c (list_command): Fixed range computation to use
416 * stack.c (backtrace_command): Do not allow command if target has
417 no stack, print informative error message.
418 * target.c (target_command): Do not write into command line
419 because this fails if the target command is used in a user defined
420 command. [This change was enhanced by gnu to support any-
421 unique-prefix matching on target names.]
422 * valops.c (value_struct_elt): Avoid infinite loop on an
423 erroneous attempt to print the member of function (try p main.p).
425 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
427 * expread.y (name_no_typename): Avoid reduce/reduce errors
428 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
429 Since the GDB parser really doesn't use name_no_typename in a
430 name-only context, the parser can't tell the diff between
431 names and numbers here. Avoid allowing a name_no_typename
432 to be a NAME_OR_*INT to resolve the conflict.
434 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
438 * valprint.c (val_print_fields): bitfield printing didn't handle
439 byte order. Indirect through a few more fns to cope.
441 * values.c (modify_field): also cope with byte order.
443 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
445 Cleanup for release 3.94.2:
447 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
448 include files. Roll version to 3.94.2.
450 * coffread.c (init_stringtab): Read length into unsigned char
451 array before swapping; don't assume 32-bit longs.
453 * target.c (target_info): Don't bother with get_sym_file, just use
454 the symfile global variable.
455 * symtab.h, symfile.c (get_sym_file): Delete it.
457 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
458 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
459 (read_type): Replace one more error() with complain().
461 * mipsread.c (parse_partial_symbols): Replace printf with complain.
463 * i960-tdep.c: Fix copyright attribution.
465 * config.gdb: Quote all backquotes in doublequotes. You can
466 quote me on that. BSD 4.4 shell found this one.
468 * infptrace.c (throughout): The third argument to ptrace is an
471 * infrun.c (wait_for_inferior): When program has terminated, we
472 have to call target_terminal_ours before we pop that target off
473 the stack (e.g. before a call to target_kill or
474 target_mourn_inferior). This fixes problem where a program
475 terminates, then GDB stops for (tty output) and you have to type
476 "fg" to the shell to resume it. FIXME: This code for what to
477 do after termination really should be in normal_stop instead.
479 * gdbcore.h (read_memory_check): Change declaration; it changed
482 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
483 4.4 prereleases, this avoids a bug in their sgtty compatability
485 * remote.c: Use terminal.h rather than hand-rolling the same.
487 * signame.c, signame.h (psignal): Arg is unsigned, not int.
488 * utils.c (strsave, strstr): Fix arg types.
489 * valprint.c (val_print): lint
491 MIPS symbol table support from Per Bothner:
493 * symfile.c (symtab_fns): Remove initializer table that needs to
494 be hacked for each new symbol file format supported.
495 (add_symtab_fns): New function, chains symbol table
496 handlers into the global list.
497 (symfile_init): Search this list.
498 * symfile.h: Add next pointer, declare add_symtab_fns.
499 * coffread.c (_initialize_coffread): Call add_symtab_fns.
500 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
502 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
503 symbol *). Thus, we no longer need the hack to trash
504 pst->filename. Good, since that hack confused code in symfile.c!
506 (reorder_symtabs, destroy_all_symtabs): Removed static
507 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
508 Instead, the latter now uses a temporary array (stack-allocated
509 from an obstack, and then freed).
511 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
512 haven't been set in the outermost stBlock of a procedure. This was
513 a problem with f77 binaries on Ultrix 4.?.
515 (new_symtab, new_symbol, new_type): Continue changing code to use
516 obstacks more and otherwise conform to dbxread internal style.
517 Made the free_code of symtabs be free_linetable (as in dbxread)
518 instead of free_contents. This implies memory leaks when reading
519 a new symbol table, until the conversion is finished. Did change
520 (struct symbol) and (struct type) to be allocated on the
521 symbol_obstack. Blocks and blockvectors are among the things
524 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
525 tested much, but it solved one problem (reported by Meissner), and
526 cleans up some other things. The problem happened when an
527 included file contains actual code (functions) and not just
528 definitions. The mips coff is a little inconvenient there, since
529 it may cause a procedure to be mapped to the wrong psymtab.
531 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
532 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
533 this will need work for the new core paradigm.
535 Opcode patches from the net:
537 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
538 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
539 missing altogether - they are added here. From Bruce Bauman.
540 * mips-opcode.h: The low mask for C0 instructions was too small.
541 From Garrett Lau. I modified the fix to check the entire 32-bit
544 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
547 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
549 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
551 * dbxread.c (read_type): Pointer subtraction (value_sub in
552 valarith.c) sometimes failed because the types of the
553 pointers being subtracted were not identical.
554 These differed because dbxread.c was allocating pointer types
555 using dbx_alloc_type+smash_to_pointer_type instead of
556 lookup_pointer_type. I failed to find a justification for the
557 former, so I changed it to use the latter. Similarly, I
558 replaced smash_to_function_type by lookup_function_type,
559 and smash_to_reference_type by lookup_reference_type.
561 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
562 _initialize_mipsread): corresponding changes.
564 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
566 * source.c (mod_path): Do tilde_expand on each component of the path,
567 rather than on the (list of) paths as a whole.
568 (print_source_lines): Set first_line_listed in addition to
569 current_source_symtab and current_source_line. If the source was
570 not findable, after a "dir" command to fix the problem,
571 a "list" would get the wrong lines.
573 While I was there... (gnu):
575 * dbxread.c (read_type): Change error to complaint.
577 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
579 First attempt at detailed understanding of symbol table memory alloc.
581 * dbxread.c (dbx_symfile_read): Free our string table if we
582 aren't the mainline. Free the "info" struct since we're done with
584 (init_psymbol_list): Free any previously allocated psymbol lists.
585 (): FIXME: Should realloc-down the psymbol lists when done reading
586 the main symbol file?
588 * symmisc.c (free_symtab): Free fullname field too.
590 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
591 (REGISTER_ADDR): Make result type unsigned int.
593 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
594 define REGEX must also define REGEX1 (its dependency).
596 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
598 * tconfig/i960: No longer works, points you at vxworks960 or

611 * gdb-int.texinfo (Host versus Target): Add section on what is
612 a "host" feature versus what is a "target" feature.
614 * infcmd.c (path_command, path_info): Handle the PATH variable
615 (object search path) as conveniently as the source search path.
616 * environ.c (set_in_environ): Set some vars in GDB's environment,
617 in addition to the child's. PATH, G960BASE, G960BIN for starters.
618 * source.c (mod_path): New function, from guts of
619 directory_command, modifies a path. Used by path_command.
620 (directory_command): Call it.
621 * defs.h (strsave): Declare.
623 * utils.c (sevenbit_strings): Add new printing option.
625 (strsave): Provide this handy helper routine.
626 (set_width_command): Rename set_screen_width_command.
627 (_initialize_utils): "set screen-width" => "set width";
628 "set screen-height" => "set height"; add sevenbit-strings.
630 * infcmd.c (do_registers_info): Print floating point registers
631 in raw hex as well as float format, regardless of whether it is
632 a "virtual" convertible register.
633 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
634 regs as a double, just in case it's being used that way.
635 * values.c (unpack_long): Comment on array/function coercion.
636 (unpack_double): Argument is in target byte order now. For
637 integer arguments, just call unpack_long and float the result.
638 * m68k-tdep.c: include defs.h for "const" handling.
639 * remote-nindy.c: Use ieee-float stuff.
640 (nindy_fetch_registers): Unpack double regs to host double, then
642 (nindy_store_registers): Pack extendeds to host double, flip
643 around by misusing unpack_double, send as target double.
645 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
646 zero, as when stopped at the first instruction of a process.
648 * blockframe.c: Fix filename in comment (param.h => tm.h).
649 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
650 * tm-68k.h: Fix typos.
652 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
654 Changes from a bringup on the DEC Vax under Ultrix 4.0.
656 * coredep.c (fetch_core_registers): Pass end-address of register
657 section to register_addr as expected. Don't call supply_register
658 if we'd just pass it garbage.
660 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
662 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
664 * target.c (push_target, target_info): Cast enums to int for < or
667 * stack.c (print_frame_info): Identify source file & line
668 even if we can't print it.
670 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
672 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)

682 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
683 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
684 double_to_ieee_extended.
685 * i960-tdep.c: Define ext_format_i960.
686 * m68k-tdep.c: Define ext_format_68881.
687 * sparc-tdep.c: Define ext_format_sparc, though unused.
688 * Makefile.dist (HFILES): Add ieee-float.h.
689 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
692 Obsolete the "coffstrip" program in favor of using BFD's strip.
694 * nindy-share/coffstrip.c: Remove file.
695 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
696 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
697 * tconfig/nindy960: Remove reference to coffstrip.o.
699 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
701 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
703 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
704 * dbxread.c: Remove static symfile_bfd.
705 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
707 * inftarg.c (child_detach): Pop the child_ops vector if the
708 detach is successful.
709 * remote-nindy.c (nindy_create_inferior): Don't push a new
710 nindy_ops since nindy uses the same one for execution and memory
712 * core.c (core_ops): Use child_attach and child_create_inferior
713 rather than default attach and create_inferior functions.
715 Handle floating point registers in core files.
717 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
718 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
719 This version untested since BFD doesn't yet support sun3 core
721 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
722 conventions. Fix comments and style. This version has not
723 been compiled yet, since we have no HP inhouse.
724 * core.c (get_core_registers): Look for two sections, ".reg"
725 and ".reg2", and pass both to fetch_core_registers sequentially.
727 Revise directory path yet again.
729 * source.c (forget_cached_source_info): Not static any more.
730 (init_source_path): New default source path is "$cdir:$cwd".
731 (dir_command): Handle variable arguments ($cdir, $cwd).
732 (source_info): Print "Compilation directory" rather than
733 "Originally compiled in" to remind people of $cdir.
734 (openp): If the path contains $cwd, use current directory.
735 (open_source_file): If compilation directory is known, replace
736 first $cdir in path with the compilation directory.
737 (print_source_lines): Even if we can't print the lines, set the
738 current symtab and line for future commands like "info source" or
739 "breakpoint". Also, error message now contains the file name,
740 line number, and file access error message.
741 (_initialize_source): Fix help text to describe changes.
742 * main.c (cd_command): Forget cached source info when we chdir.
743 * utils.c (strstr): Add simple implementation.
745 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
747 * coffread.c (read_one_sym, init_linetable, init_stringtab):
748 Byte-swap COFF symbol tables if necessary when reading them in.
749 Use complain() to replace error message in one spot. Needs
750 corresponding change in bfd/coff-code.h to make some symbol
751 swapping routines non-static.
753 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
755 Merge changes from Eirik Fuller, for UTek.

760 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
761 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
762 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
763 declarations of errno.
765 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
767 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
768 <rpc/rpc.h> and <rpc/types.h>.
770 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
772 * i960-tdep.c (examine_prologue): Add new argument limit,
773 which stops the scan at the end of the prologue, or at the PC.
774 This fixes a problem where it walks down into the code for the
775 user's statements if that code looks like function prologues.
776 Mark Fox and I have been bouncing this code back and forth, making
777 small changes to it. Callers changed to match.
779 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
781 Cleanup for gdb-3.94 release final:
783 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
784 the .c files from vx-share and nindy-share, from the various
785 macros, since they are not found via ALLDEPFILES.
786 (SFILES): Add tm-i960.h.
787 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
788 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
790 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
791 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
793 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
795 * am29k-tdep.c: Add contribution line.
796 (examine_prologue): Cache information about function prologues in
797 the misc-function-vector to avoid lots of references over the
798 serial line while examining instructions.
800 * core.c (core_close): New function made from cleanup_core.
802 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
803 remote-vx.c, remote.c, target.c, target.h,
804 Update target_ops vector to add attach, close, and load entries.
805 Use add_syms_addr_command, not add_file_addr_command, for
806 add_file. Break out close routine from existing code.
808 * dbxread.c (really_free_pendings): Don't free pending_blocks;
809 they are in an obstack.
810 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
812 (define_symbol): Add symbol type parameter; change callers;
813 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
814 it to influence the symbol class on the i960.
815 (define_symbol): Swap LOC_CONST's into target byte order.
817 * exec.c (exec_close): New function.
818 (exec_file_command): Call it.
820 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
821 Fix byte order of frame pointer.
822 (read_var_value): Result of 0 if var's value can't be found,
823 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
824 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
825 (locate_var_value): Use read_var_value and use its lazy address
826 as the location of the var's value. Lint.
828 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
831 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
832 obsolete Intel versions in favor of vxgdb versions.
833 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
834 code dealing with byte order of values, which Intel did in host byte
835 order rather than gdb-4's target byte order.
836 (i960_frame_chain_valid): Move to nindy-tdep.c.
837 (examine_prologue, skip_prologue, frame_find_saved_regs,
838 frame_args_address, leafproc_return, saved_pc_after_call,
839 pop_frame): Add vxgdb versions from Mark Fox.
840 (examine_prologue, frame_struct_result_address): Add code
841 to deal with the saved value of G13 (struct return address
843 (frame_args_address): Modify Mark's version to prefer the
844 saved value over the current value in the topmost frame.
845 Cache result in the frame info to avoid performance hair in
847 (print_fault): Add gdb960 code for printing faults.
848 (_initialize_i960): Actually call check_host.
850 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
851 add stub routines. FIXME, these currently just return zero!
853 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
854 (attach_command): Call target_attach, not target_open, now.
856 * infrun.c (normal_stop): Make global, not static, for vx_attach.
857 (child_attach): Rename from child_open.
858 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
859 don't confuse it with a zero step_resume_break_address.
861 * inftarg.c (child_detach): Eliminate inferior_pid test.
862 (child_files_info): Clean up message a bit.
863 (child_ops): Use child_attach, not child_open, to attach.
865 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
866 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
867 findvar.c to here, since it depends on the contents of the
868 shadow_contents of breakpoints, but keep if #if 0 since it is
871 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
874 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
875 (ptype_command, display_command): Eliminate have_inferior_p and
876 have_core_file_p in favor of target_has_stack or
877 target_has_execution.
878 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
879 code for actually finding the values of arguments, though we still
880 keep track of the maximum stack offset for use in printing unnamed
881 arguments. Handle missing FRAME_ARGS_ADDRESS.
883 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
884 (struct nindy_regs): Define registers passed to/from nindy.
885 (nindy_fetch_registers, nindy_store-registers): Translate between
886 nindy and GDB formats for the registers.
887 (dcache_init): Statically allocate the cache, since it was being
888 allocated by a malloc that was never freed anyway.
889 (nindy_create_inferior): Error, not core dump, if no exec file.
890 (nindy_before_main_loop): Use target_load, not target_add_file.
892 * remote-vx.c (net_load): Specify large timeout for load
893 requests. Allow user to break out with INTERRUPT.
894 (net_break): Remove useless code, clean up. Change callers.
895 (parse-args, skip_white_space, find_white_space): Clean up arg
896 parsing to cope with quoted strings.
897 (net_wait, net_quit): Never call error, just return status.
898 (vx_read_register, vx_write_register): Cleanup status checking.
899 #ifdef the code based on which CPU we are using (960 or 68k),
900 FIXME, this should be completely general but it isn't yet.
901 (vx_xfer_memory, vx_resume): Cleanup status checking.
902 (vx_run_files_info): Improve message.
903 (vx_load_command): Renamed from vx_add_file_command. Allow load
905 (net_ptrace): Remove unused routine.
906 (vx_wait): Adopt code from vxgdb960 to cope with broken
907 connections to target machine and prompt to disconnect. Remove
908 debug printouts. Map some EVENT_'s to SIGnals.
909 (add_symbol_stub, vx_open): Print names of object files we found,
910 and "ok" if we read their symbols OK. Clarify output in general.
911 (vx_attach, vx_detach, vx_kill): Add these commands.
912 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
913 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
914 "info files" output, and create_inferior, since we already have
917 * stack.c (frame_info): Replace Frame_unknown with 0.
918 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
919 (return_command): Pop until the PC matches as well as the FP,
920 so it works even if the FP is shared with another function,
921 as in "frameless" or "leaf" procedures.
923 * symfile.c (load_command): renamed from add_file_target_command.
924 (add_syms_addr_command): renamed from add_file_addr_command.
925 (add_syms_command): Stub to call target_add_syms.
926 (_initialize_symfile): Change command names and descriptions,
927 add-file => add-syms, and load from alias to its own command.
929 * target.c (kill_or_be_killed, maybe_kill_then_attach,
930 maybe_kill_then_create_inferior): Default for attempts to start
931 a process, if one is already running, is to ask about killing
933 (upstack_create_inferior): #if-0 it, strata obsolete it.
934 (push_target, unpush_target, pop_target): to_close() a target
935 before unstacking it.
936 (target_info): Renamed from target_files_info.
937 (_initialize_targets): Rename "i files" as "i target", accessible
940 * target.h: Improve comments about the target_ vectored routines.
942 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
943 Convert commenting style to standard GNU style.
944 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
945 (SKIP_PROLOGUE): No longer a no-op.
946 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
947 (*_REGNUM): Sort register numbers.
948 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
949 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
950 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
951 are now 10 byte extendeds, not 8 byte doubles.
952 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
953 for nindy versus vxworks targets. FIXME, this should possibly go
954 in the target vector.
955 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
956 frame_saved_regs and arg pointer with each frame.
957 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
958 (FRAME_ARGS_ADDRESS): Use cached result.
959 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
960 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
961 (PRINT_RAMDON_SIGNAL): Call print_fault.
962 (POP_FRAME): Now works.
964 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
965 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
966 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
967 (ADDITIONAL_OPTION_HANDLER): use target_load, not
970 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
971 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
973 * valarith.c (value_subscripted_rvalue): Avoid handling
974 floats and doubles specially; it gave alignment errors. Lint.
976 * valops.c (value_of_variable, value_of_this): Error if unknown
979 * valprint.c (print_floating): Bcopy rather than pointer-deref,
980 to avoid alignment problems.
981 (value_print): Handle unknown value address.
982 (cplus_val_print): Two args are ignored; remove them. Change caller.
983 (val_print): Use unpack_long rather than pointer-deref.
986 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
987 to avoid alignment problems.
988 (value_being_returned): Error if return value unknown.
989 (set_return_value): Add bogosity warning, FIXME. *
991 * TODO: A woman's work is never done.
993 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
994 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
995 Add ieee-float.o to OBS.
996 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
997 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
998 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1000 Changes to generalize the VxWorks RPC protocol slightly, to handle
1001 i960 as well as 68000.
1003 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1004 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1005 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1006 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1007 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1008 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1009 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1010 so they will move in target byte order rather than network
1011 byte order (happens to be the same).
1013 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1015 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1017 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1020 Add contribution lines to various files, showing where they
1023 * breakpoint.c (break_insn, check_break_insn_size,
1024 read_memory_nobpt): Remove to mem-break.c.
1026 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1029 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1030 entry has bad register number. This change is not
1031 tested in this release, FIXME.
1033 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1036 * value.h: Force value's contents field to be aligned to hold
1037 at least a double or a long long (if supported). This avoids
1038 doing bcopy's in and out of the contents field.
1040 (step_1): Avoid coredump under obscure circumstances when we
1043 * symtab.h (misc_info): Add field to misc function vector for
1044 any kind of cached information the target code desires. AMD
1045 29000 uses this to avoid repeating examine_function_prologue's.
1047 * coffread.c: Lint. Remove static symfile, read_section_header.
1048 core.c (have_core_file_p): Lint: remove.
1049 expprint.c (print_subexp): Lint.
1050 infptrace.c, valops.c, valprint.c: lint.
1052 Roll in changes from vxgdb-5.0.1:
1054 * symtab.h: Comment byte order of each address class. Add
1055 LOC_LOCAL_ARG for frame-relative args (960).
1056 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1057 symtab.c, symmisc.c: ditto.
1059 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1061 * remote.c (remote_resume): Error if resume with a signal.
1063 * symfile.c (prim_record_misc_function): Clear misc_info.
1064 (fill_in_vptr_fieldno): Check stub type of arg.
1066 * valops.c (value_cast): Avoid looking up names of types whose
1067 name we don't know, to prevent coredump. Sun CC produces typedef
1068 rtx and the name of *rtx is zero...
1070 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1072 Roll in changes from final AMD 29000 port (Tiemann).
1074 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1075 for ../include/a.out.encap.h. This might not work now that BFD
1076 is separately compiled. Instead, BFD support for encap will have
1077 to translate machine type 29k into the right COFF_MAGIC.
1079 * infcmd.c: Remove references to inferior_pid that aren't used
1080 in actual ptrace calls; use target_has_execution, etc.
1081 (have_inferior_p): Remove function.
1082 (program_info): Print target info rather than "process number";
1083 avoid gratuitous messages unless from_tty.
1084 (run_stack_dummy, finish_command): Set proceed_to_finish.
1085 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1086 main.c: Lint. Lose have_inferior_p().
1087 inferior.h (have_inferior_p): Remove, lint.
1088 (proceed_to_finish): Add flag to ask that all regs be saved
1089 by normal_stop, for the few commands that need it, speeding up
1090 serial I/O. Add comments to stop_registers.
1092 * remote-eb.c: Remove newline from breakpoint message we grep
1093 for. Never time out when running the user program.
1097 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1099 Roll in changes from vxgdb-5.0.1:
1101 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1102 symbol in its raw form, we are processing an unlinked ".o" file.
1103 See if the target environment has assigned it an address, using
1104 target_lookup_symbol (VxWorks does), and enter it into the symtab
1107 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1108 68k versions for a simpler version that assumes zero FP at bottom.
1109 Fixes bug of truncated stack reports.
1111 * target.h (target_lookup_symbol): Define this routine's args
1112 and result, finally.
1114 * target.c (nosymbol): Default routine for target_lookup_symbol.
1115 (target_default): Default lookup_symbol and call_function too.
1116 (files_info): Only print has_all_memory warning if a non-dummy
1119 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1120 vx_convert_from_virtual): If target does not have floating point,
1121 zero register "values", and avoid doing cross-net conversions.
1122 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1123 (vx_open): Rearrange code that attaches to target and reads
1124 symbols for all loaded modules, to work if some of the modules
1125 are not accessible. Add symbol_stub() and add_symbol_stub()
1126 as callbacks from catch_errors(). Allow connect attempt to be
1127 interrupted painlessly with ^C (FIXME, there are still some bugs
1128 if the interrupt happens during symbol reading.). Print
1129 final message with puts_filtered, since symbol messages are
1134 * main.c (catch_errors): Only print errstring if non-null.
1135 (command_loop): Avoid an ioctl per command to test ISATTY.
1137 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1138 (vx_xfer_memory): Return correct result!
1139 (vx_files_info): Indicate whether target has float or not.
1140 (vx_lookup_symbol): Complain, not error, if target gone.
1141 (vx_open): Print "Connected" msg before disabling immediate-quit.
1142 [FIXME: lookup_symbol and vx_open changes need testing.]
1144 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1145 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1146 contributor lines and update copyrights to 1991.
1148 Changes from an attempted H-PUX host port:
1150 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1151 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1152 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1153 * remote-vx.c: include <sys/time.h> for HPUX.
1154 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1155 "core_file_command" routine to BFD regime. May not work yet.
1157 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1159 * xgdb.c: Replace X10 version with some VJ version.
1160 (FIXME: Its copyright assignment is not on record.)
1161 * xgdb.c: Update include files to X11R4 (Xaw crud).
1162 (xgdb_display_source, create_text_widget): fix call to
1163 get_filename_and_charpos. Rewack source window stuff for X11R4
1164 (gleaned from include files, and "nm's" of binary libraries, since
1165 I had no doc available).
1166 (append_selection, append_selection_word): Disable with FIXME
1167 since R4 changed interface here.
1168 (create_buttons): Add back the old set of buttons.
1169 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1171 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1172 Roll VERSION to 3.94 (not yet final though).
1174 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1176 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1177 obstack_int_grow, obstack_int_grow_fast): Eliminate
1178 cast on left of assignment, which gives MIPS cc fits and is
1181 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1182 F_ALIAS. Use printf, not fprintf, when not passing a file
1184 (compare_opcodes): Check that identical instructions have
1185 identical opcodes, complain otherwise.
1187 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1188 was reported by Roland McGrath.
1189 (unimp): Only match if exactly zero instruction. (Roland)
1190 (branches and traps): Generate all variations of these
1191 instructions with macros, based on a single call that defines
1192 each condition name and its binary representation.
1193 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1195 * valprint.c (val_print_fields): Take, and use, format parameter.
1196 This means that "p/x struct" again prints the elements in the
1197 desired format. Changed callers.
1199 * stack.c (frame_info): Use filtered output, and indicate wrap
1200 points. Remove kludgy formatting designed to avoid line wrap.
1202 * utils.c (wrap_here): If the line is already full (because
1203 we had printed a long indent or long wrapped string), do an
1204 immediate newline-and-indent.
1206 * m68k-pinsn.c (print_insn_arg): Bugfix from
1208 instruction is incorrectly disassembled as bkpt #8.
1210 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1212 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1213 and then will dump core (sometimes). I traced it back to an
1214 uninitialized symfile_name in psymtab_to_symtab.
1215 (const_vol_complaint): Add quotes to message.
1216 (define_symbol): Only believe line number if gcc_compiled.
1217 Avoid allocating symbol if we will not return it.
1219 Add target strata support so that newly established targets go
1220 into their right place in the target stack (e.g. a new exec file
1221 doesn't wipe out the ability to access the running process).
1223 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1224 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1225 and initialize it properly in all the targets.
1227 * target.h: Document strata. Change return type of push_target.
1229 * target.c (nomemory): new function for dummy memory access.
1230 (tcomplain): Rename complain, now also used in symfile.c.
1231 (push_target): Push targets within strata. New return value shows
1232 whether new target is on top of stack or not. Always keep dummy
1234 (target_files_info): Ignore dummy target.
1236 * core.c (core_open): Warn user, and skip accessing file, if the
1237 core target is not the topmost target in the stack.
1238 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1241 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1242 target_ops, it doesn't belong there since we have no regs there.
1243 Change name of target from machine => memory to clarify.
1245 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1247 * Freeze version 3.93 for release.
1249 * Makefile.dist: Handle vx-share and nindy-share subdirs
1250 properly when building gdb.tar.Z.
1252 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1253 printed in various places, so I could change just one copy.
1255 * dbxread.c, coffread.c: Change references to bfd->iostream
1256 to cast to FILE *, now that BFD avoids needing types defined
1257 in other header files.
1259 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1261 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1262 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1263 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1264 (actually gcc -Wall).
1266 * dbxread.c: Remove first_global_sym, last_global_sym, since
1267 they are never referenced.
1269 * defs.h (baud_rate): Declare.
1270 main.c: Define it, and add the -b option to set it.
1272 * gdb-int.texinfo: Add text on how to define a new host or target
1273 architecture, prompted by Per Bothner's questions about MIPS
1276 * gdb.texinfo: Document "complaints". Change doc of -q since
1277 gdb no longer prints the copyright and blurb if you specify a file
1278 name to be debugged (just like Emacs). Add doc for Nindy-specific
1279 command line flags for specifying target serial port and such.
1280 Update copyright to 1991.
1282 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1283 has taken over for us the job of ripping up executable files. The
1284 crud caused Per Bothner's port to not compile.
1286 * infrun.c (normal_stop): Avoid printing "Program exited
1287 normally" if we are in batch mode. This allows a GDB which
1288 executes a program on a target system, to behave like a Unix
1289 command (input from stdin, output to stdout, no extraneous
1292 * main.c (main): Allow additional machine-dependent command line
1293 options to be specified with the ADDITIONAL_OPTIONS,
1294 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1295 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1296 processing to occur just before the main loop with
1297 BEFORE_MAIN_LOOP_HOOK.
1298 (main): If a "core file" argument is specified, and it is not a
1299 core file, try it as a process ID to attach.
1300 (symbol_completion_function): Attempt to cope with
1301 "show screen-" TAB, not very successfully. This needs more work,
1303 (batch_file): New function, returns whether we are reading
1304 commands from an interactive tty on stdin, or from somewhere else.
1305 Called by normal_stop since it doesn't get from_tty passed down
1306 to it like many commands do.
1308 * remote-nindy.c: Handle command line options for nindy
1310 (nindy_before_main_loop): Prompt user for tty name if they
1311 don't specify it before getting to the interactive command loop.
1313 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1314 and -r command line options. Also add hook before main loop
1315 to make it easy to specify a tty.
1317 * TODO: More things to do, one done.
1319 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1321 * dbxread.c: Make complaint() calls pass pointer, not struct.
1322 Add complaints about badly formatted C++ type information
1323 (const/volatile indicator, and parse errors resulting in
1324 error_type). Fix C++ virtual member fn comment.
1325 (read_struct_type): Avoid bumping pointer if we got a parse
1326 error; this prevents our walking beyond the end of a string.
1327 Terminate loop on null char as well as semicolon.
1328 (process_one_symbol): Fix the LBRAC fix so that it uses the
1329 last previous SLINE, FUN, or SO record's PC address. C++ debug
1330 symbols did not have SLINE records in a useful order compared
1331 to the LBRAC records.
1332 (define_symbol): Handle "catch" records.
1334 * symtab.c (check_stub_type): Added new complain
1335 `stub_noname_complain' and added a consistency check to
1336 keep the debugger from crashing when finishing from an
1337 exception frame. A real fix will be needed later.
1339 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1341 * infcmd.c (attach_command): Make global.
1343 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1344 but make them easy to comment out. Perhaps later they should
1345 be enabled by what CPU you configure for? FIXME.
1346 (VERSION): Roll to 3.93.
1347 (pinsn.o): Remove rule for obsolete file.
1348 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1350 Run down a problem that manifested by printing the wrong function
1351 name in stack traces of read_ofile_symtab. Turned out that the
1352 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1353 the LBRAC symbol with an address in the *data* segment, which
1354 blew our binary search through the blocks.
1356 * dbxread.c: Use the complain() facility consistently to bitch
1357 about problems in the symbol file we are reading.
1358 (finish_block): Add code to check the nesting of the blocks;
1359 complain and Procrust them to fit if wrong.
1360 (make_blockvector): Check the order of the blocks, complain
1361 [but don't cope] if wrong.
1362 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1363 symbols to be sure their PC value is greater than the last SLINE
1364 (line number) symbol we've seen, complaining and adopting the
1365 SLINE PC value if wrong.
1367 * symfile.h (struct complaint, complaint_root, complain,
1368 clear_complaints): Add.
1369 * symfile.c (complain, complaint_root, clear_complaints): Add
1370 facility to deal with non-fatal complaints and to regularize their
1372 (symbol_file_add): Clear complaint counters to allow new complaints.
1373 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1375 * dbxread.c (dbx_symfile_read): Remember the address and size
1376 of the string table for the main symbol file, so we won't read it
1378 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1379 to avoid reading the string table yet again. Lint.
1380 (throughout): Improve filtered output, including word wrap.
1381 (read_range_type): Improve Bothner's fix to handle other types too.
1383 * utils.c: Improve line wrap implementation. Handle unlimited
1384 width by making chars_per_line unsigned.
1385 (puts_filtered): New, easy, function.
1387 * defs.h (puts_filtered): add.
1389 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1390 call the identical sort_symtab_syms() in symfile.c instead.
1392 * expread.y: Suggest the `file' command rather than `symbol-file'.
1394 * command.h (enum var_types): Add zinteger for seroable
1396 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1397 nested if's into a switch.
1399 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1400 we did not stop because of a breakpoint (it must have been for
1401 some other reason, like a "stepi"), so don't print anything.
1403 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1404 doesn't include <sys/types.h>, old SunOS's require it for
1409 A test port of gdb-3.92.6 to the Sony NEWS.
1412 Don't normally link in remote- or vx stuff.
1413 Some of it doesn't compile, and it wastes space for 99% of the users.
1414 Remove reference to no-longer-used HAVE_VPRINTF.
1415 Fixed BFD_DEP typo to BFD_DIR.
1417 Fix cast in arg to bfd_h_getlong.
1418 Make char *prefix be const.
1419 Fix how certain range types are mapped into builtin unsigned int types.
1421 Remove 2 #includes. They cause errors (on Sony, at least),
1422 and aren't needed (they wern't in earlier versions).
1424 print_address_symbolic should never demangle labels
1425 (since it prints *assembler-level* labels).
1427 [This was superseded by the change to printcmd below.]
1430 Add some "volatile" return types to avoid warnings.
1431 If MISSING_VPRINTF add vprintf function and not just macro
1432 (since vprintf is used in printcmd.c).
1434 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1435 (The latter isn't grokked by some PCC-based compilers.)
1437 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1439 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1440 * nindy-share/coffstrip.c
1441 Added some forward declarations (otherwise, gcc complains
1442 about implicit extern redefined as static).
1444 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1446 Changes inspired by Per Bothner:
1447 * printcmd.c (print_address_symbolic): Take additional parameter
1448 specifying whether to demangle.
1449 (print_address): Pass in asm_demangle to control demangling.
1450 (print_address_demangle): New fn, takes explicit arg to control
1452 * utils.c: Add new vars demangle and asm_demangle, and let them
1454 (fputs_demangled): If !demangle, just print the argument.
1455 (fprint_symbol): If !demangle, just print raw symbol.
1456 * valprint.c (val_print): Call print_address_demangle rather than
1457 print_address, to cause demangling to depend on the global
1458 rather than assembler-level demangling setting.
1459 * WHATS.NEW, gdb.texinfo: Document.
1461 * main.c (show_command): Show all settings if no arg.
1462 (initialize_main): Make "info set" the same as naked "show".
1463 * command.c (cmd_show_list): Handle prefix commands in the
1464 list, and print the name of the setting as well as its English
1465 description and value.
1467 Allow gdb functions to specify where a line should wrap if it
1468 exceeds the size of a terminal line. Use it to make the output
1470 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1471 of the right size when screen width changes.
1472 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1473 (wrap_here): New fn, indicates a point in the output where we
1474 should wrap the line rather than just letting it overflow at a
1476 (fputs_filtered): Implement wrapping.
1477 (n_spaces): New fn, returns a pointer to N spaces.
1478 (print_spaces_filtered): Use n_spaces.
1479 * defs.h (n_spaces): Declare.
1480 * stack.c (print_frame_info): Wrap with 4-space indent after
1481 fn name and before filename and line number.
1482 * printcmd.c (print_frame_args): Wrap with 4-space indent
1483 before each argument name is printed.
1484 * valprint.c (value_print): Wrap with no indentation before
1486 (val_print_fields): Wrap with indentation relative to nesting
1487 level before each field name.
1488 (val_print): Wrap with nesting indentation before array elements.
1489 * command.c (do_setshow_command): Avoid extra newlines,
1490 wrap with 4-space indent around values printed, end with period.
1491 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1493 * breakpoint.c (breakpoint_1): Implement addressprint for
1494 "info breakpoints" display. Change file name and line number
1495 format to " at file:nnn" rather than " (file line nnn)".
1496 * gdb.texinfo: Document.
1499 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1501 Frozen for gdb-3.92.6 release.
1503 README, WHATS.NEW: Update for 3.92.6 release.
1505 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1506 coffread.o from configs since it is now built by default.
1507 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1508 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1509 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1510 from configs since it is now built by default.
1512 Makefile.dist: Update for release 3.92.6. Handle files that
1513 have been moved to ../include, ../getopt, or ../bfd. Add
1514 saber.suppress and tests directory. Add config.status to
1515 the release (it will say "none").
1517 coredep.c: Minor formatting fixes.
1519 These changes were made in early December but only checked in now:
1520 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1521 nindy-share/nindy.c: lint
1522 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1523 register values coming back from the target; we store values
1524 in target byte order everywhere.
1526 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1528 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1530 * valprint.c (cplus_val_print, val_print_fields): New functions,
1531 which print C++ objects. They conspire to avoid printing a
1532 virtual base class more than once, following all the twists and
1533 turns of C++ virtual base rules.
1534 (val_print): Call the above rather than do it by hand.
1536 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1537 symbol file, not for added files like shared libs. This really
1538 needs to be generalized to a timestamp per file.
1540 * core.c (cleanup_core): Avoid coredump if no core file.
1542 * config.gdb: Accept -host or -target in place of +host or
1545 * coffread.c (find_linenos): Avoid desupported BFD interface
1546 to line numbers. We still read them manually rather than using
1547 BFD's "generic" features.
1549 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1551 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1553 * Makefile.dist: Eliminate use of $< in explicit targets.
1555 * readline/Makefile: Use $< rather than $*.c, which does not
1556 include the VPATH in GNU Make.
1558 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1559 copies of tconfig/i960, added for global configuration
1560 compatability. All i960 versions can read both coff and b.out.
1562 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1563 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1566 * TODO: Think of more things to do.
1568 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1570 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1571 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1572 64-bit float conversion.
1574 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1575 equivalent to sun?os4 so global config works.
1577 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1581 * main.c: Only declare linesize once; declare pagesize not at
1582 all, since it is never used.
1583 (main): Clear newly allocated line before it is used.
1585 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1587 Further stabilization for the Intel 960.
1589 * Makefile.dist: Parameterize the location of the "include"
1590 and "bfd" directories, as well as "getopt". Add symfile.c.
1591 Link in both dbxread and coffread. Fix up "make depend" to
1592 rewack the locations of include, bfd, and getopt in its output.
1594 * README: Document moving include files, improve some of
1597 * coffread.c: Move common code out to symfile.c. Change
1598 symbol_file_command style interface to use new *_symfile_init
1599 and *_symfile_read interface under BFD. Use BFD internal
1600 info to locate line table, symbols, etc.
1602 * core.c (core_fetch_registers): Rename to get_core_registers
1603 to avoid confusion with fetch_core_registers.
1604 (register_addr): Move to coredep.c, which is already machine
1605 dependent. This leaves core.c pretty clean of dependencies.
1607 * coredep.c (register_addr): Accept this routine from core.c.
1609 * dbxread.c: Move common code (with coffread.c, etc) into new
1610 symfile.c. Each psymtab now contains a pointer to the
1611 format-dependent function that knows how to read it in. Make
1613 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1614 (process_one_symbol): Add code to complain about a "compiler bug
1615 we muzzle here", if we actually see it.
1617 * eval.c (evaluate_subexp): Insert missing "break" statements
1618 in code that determines whether a variable is an lvalue in
1619 memory, register, or whatever. I detected this via a compiler
1620 bug in which it *almost* mashed out the whole switch statement.
1622 * gdb-int.texinfo: Add minor sections on configuring gdb for
1623 release, and about the README file.
1625 * infcmd.c (registers_info): Fix formatting somewhat. Still
1626 not as pretty as before, but it handles byte swapping.
1628 * remote-nindy.c: If data cache routines are interrupted while
1629 waiting for the remote end, be sure that any uninitialized cache
1630 blocks are on the free list, not on the valid list!
1632 * symfile.h: Flesh out this header file with all the various
1633 routines and variables that have been merged in from dbxread.c
1634 coffread.c, and symtab.c to symfile.c.
1636 * symfile.c: New file, containing code common to dbxread.c,
1637 coffread.c, and some code from symtab.c. All generic code for
1638 reading symbol files should be in here now.
1639 (unrecord_misc_function): Remove unused function.
1641 * symtab.h: Remove file-reading things to symfile.h.
1643 * symtab.c: Remove file-reading things to symfile.c.
1645 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1646 to decode i960 fault types.
1648 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1649 target.c: Change type of the "resume" function from int to void,
1650 since its result was never used.
1652 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1654 * main.c: Replace "stupid" with "caution"; you now "set caution
1657 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1659 * infcmd.c (do_registers_info): Call val_print to deal with the
1660 byte order of the registers being printed. FIXME, this makes
1661 the formatting of the output uglier.
1663 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1664 defined, call it for signals the debugger doesn't itself use.
1665 The i960 uses this for more detailed fault information.
1667 * remote.c (remote_open): If arg is null, print help rather than
1670 * sparc-xdep.c (register_valid): Avoid declaring size, since
1671 various modules will think of various sizes depending on the
1672 architecture of their tm-file. FIXME, we need protection against
1673 actually entering one of those modules, which would clobber
1674 storage if not for the target architecture compiled into gdb.
1676 * stack.c (up_command, down_command): Always print the frame
1678 (up_silently_command, down_silently_command): New commands
1681 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1683 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1684 more parameters than it used to.
1686 * findvar.c (registers): Increase slop to 256 bytes, which should
1687 protect us against even most RISC machines with large register
1689 (locate_var_value): Move declaration inside related ifdef.
1691 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1692 throughout, to avoid throwing away buffered input from the board.
1693 (nindy_wait): Supply_register takes addr_of_value, not value.
1694 (i960_print_fault): Renamed from i80960_fault.
1695 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1696 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1698 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1699 we can set the PC in the call to proceed(). Unpush nindy_ops
1700 before pushing it on top, to avoid message to user. Eliminate
1701 commentary from Unix machines that just misleads here.
1702 (reset_command): Fix error message to suggest target command.
1704 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1706 Release 3.92.5 as frozen.
1708 Stabilize the merged release...with help from lint, Saber C,
1711 Everywhere: Add include files needed to declare return types
1712 of functions called.
1714 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1716 * breakpoint.h: Add undeclared breakpoint functions, and some
1717 functions for display handling since I couldn't think of a better
1720 * breakpoint.c (insert_breakpoints): Make code for disabling
1721 shared library bkpts more likely to work. It's used when we
1722 rerun a program and stop before the shared library has been
1724 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1725 cast from pointer, so it squeezes through catch_errors.
1726 (bpstat_stop_status): Fix logic broken some time ago. We now
1727 always create a bpstat if the stop address matches a breakpoint,
1728 even if we don't stop there -- just like the old code used to do
1729 before I got my fingers into it (sigh).
1730 (breakpoint_1): Print "ignore count" after "stop only if"
1731 condition, since that's how it actually works.
1732 (mention): Handle watchpoints as well as breakpoints.
1733 (watch_command): use set_raw_breakpoint and mention to do most
1734 of the work (and initialize all the fields!). Only pass one
1735 arg to parse_c_expression, since that's all it takes.
1737 * command.c (not_just_help_class_command): Rename arg to args
1738 since we ignore "unused argument" warnings on vars named "args".
1739 inflow.c (child_terminal_info): ditto.
1740 infptrace.c (kill_inferior): ditto
1741 main.c (catch_errors, version_info, quit_command, pwd_command,
1742 source_command, dump_me_command, editing_info,
1743 set_history_size_command, set_history, show_history,
1745 stack.c (locals_info): ditto
1746 target.c (target_files_info): ditto
1747 valprint.c (set_input_radix, set_output_radix): ditto
1749 * core.c: Remove old variables for handling core and exec file
1750 sections (data_start, data_end, stack_start, stack_end,
1751 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1752 text_end, exec_data_start, exec_data_end, text_offset,
1753 exec_data_offset, data_offset, stack_offset). They're
1754 superseded the more general build_section_table and
1756 (get_exec_file): Mention the `file' command.
1757 (read_memory_check): Rename to memory_error, and only call it
1758 in the case of an actual error.
1759 (read_memory, write_memory): call memory_error.
1760 (core_fetch_registers): Register section name is ".reg".
1762 coredep.c: Remove a bunch of crud now that all this file does
1763 is pull the registers out of a core file.
1764 (fetch_core_registers): Rewrite to actually work, I hope.
1766 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1767 Replace index() with strchr(). Remove all the pre-BFD macro
1768 definitions for accessing the symbol file.
1769 (struct dbx_symfile_info): Encapsulate the information that
1770 dbx_symfile_init needs to pass to dbx_symfile_read in this
1773 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1774 dbx_symfile_discard): Rearrange symbol file reading to divide
1775 the format-specific part from the format-independent part,
1776 leaving the format-independent part such as file name expansion
1777 and opening in symtab.c. This replaces
1778 partial_symbol_file_open and partial_symbol_file_read.
1779 Symbol_file_read, add_file, add_file_target_command,
1780 add_file_addr_command move to symtab.c. Pass an explicit
1781 "mainline" flag for when reading the main symbol table, rather
1782 than relying on the offset address to be zero or nonzero.
1784 (dbx_symfile_read): Don't allow void *'s to be printed as
1786 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1787 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1788 macro" debug version really work.
1789 (read_dbx_symtab): Remove unref'd parameter inclink.
1790 Avoid swapping N_SLINE symbols, for speed.
1791 Merge N_TEXT!N_EXT case with the other external symbol
1792 definitions' case. Add comments.
1793 (start_psymtab): Allocate the symfile name in the psymtab on
1794 the psymbol_obstack, rather than using the caller's storage.
1795 (end_psymtab): Only allocate a dependencies list if there are
1797 (psymtab_to_symtab_2): Use BFD when reopening file to read
1798 its symbols for real.
1799 (read_struct_type): Add FIXME comments where it needs work
1801 (read_huge_number): Add FIXME about overflows.
1802 (read_range_type): Add FIXME about comparing a long to 1<<32.
1804 * coffread.c: Minor changes to move things closer to the new
1805 regime with symtab.c and dbxread.c Major work is still needed
1808 * exec.c (exec_file_command): Remove old variables (see core.c
1810 (xfer_memory): If memory transfer is right at the end of a
1811 section, don't lose.
1813 * findvar.c (get_saved_register): If value is in a real
1814 register, LVAL is lval_register, not lval_memory.
1816 frame.h: Declare print_sel_frame and record_selected_frame.
1818 gdb-int.texinfo: New file, for GDB internals documentation.
1819 Very simple, unformatted doc of cleanups is there for now.
1821 gdbcore.h: Remove obsolete variables that described a.out
1822 section addresses and offsets. (See core.c above.)
1823 Declare fetch_core_registers and registers_fetched.
1825 getopt.c: Declare char *alloca(); even on SPARC.
1827 infcmd.c (run_command): Call target_kill rather than
1829 (step_command, next_command, stepi_command, nexti_command):
1830 Declare from_tty parameter even though we don't use it.
1831 (run_stack_dummy): argument BUFFER is a char array, not
1832 a pointer to REGISTER_TYPE.
1833 (finish_command): using_struct_return needed a value *,
1834 not a struct symbol *.
1836 * infptrace.c (child_xfer_memory): To avoid dependency on
1837 where sections are in memory, try PT_WRITE_D and if that fails,
1838 try PT_WRITE_I. Most Unixes don't care which you use.
1840 * infrun.c (step_resume_break_shadow): Change to array to
1841 match other breakpoint shadow storage.
1842 (clear_proceed_status): Pass address of bpstat to
1843 bpstat_clear, not the bpstat itself.
1844 (child_create_inferior): FIXME comment about if the child
1846 (start_inferior): Remove old function.
1847 (child_open): Use target_kill rather than kill_inferior.
1848 (wait_for_inferior): Ditto.
1849 (insert_step_breakpoint, remote_step_breakpoint): Use
1850 new step_resume_break_shadow.
1852 * inftarg.c (child_wait): If all child processes die,
1853 pretend that the one being waited for exited with signal 42.
1855 * main.c (command_line_input): When scanning for comments,
1856 don't coredump on unclosed quotes.
1857 (quit_command): Use target_kill rther than kill_inferior.
1858 (_initialize_main): Rename class_user from "user" to
1861 * printcmd.c (print_command_1): Initialize "fmt" if no format
1862 is specified by the user.
1863 (print_frame_args): Only add to args_printed if we are
1864 actually fetching args from the stack (avoiding undefined
1866 (_initialize_printcmd): Remove bogus \{ from string.
1868 * remote-eb.c (eb_open): Avoid coredump on no argument.
1870 * remote-nindy.c: Bring out of Intel environment into new
1871 target environment. Remove all conditional compilation on
1872 I80960. Massive hacking throughout.
1873 (nindy_xfer_inferior_memory): New routine stolen from
1875 (nindy_create_inferior): New routine pieced together, probably
1876 not quite working yet.
1877 (nindy_ops): New target_ops struct for nindy.
1879 * remote-vx.c: Use write_memory rather than target_write_memory
1880 to get error checking.
1881 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1883 (vx_create_inferior): Use target_terminal_ours...
1885 * signame.c (_initialize_signame): Always initialize, since
1886 we need the table for things other than psignal.
1888 * solib.c (solib_add): Use symbol_file_add, not add_file.
1889 (solib_address): Return boolean result rather than struct
1890 pointer which nobody else knows the type of.
1892 * sparc-tdep.c, valops.c: Use write_memory rather than
1893 target_write_memory, to get error checking.
1895 * stack.c (locals_info, catch_info, args_info,
1896 get_selected_block, frame_command, up_command): Use
1897 target_has_stack, rather than have_inferior_p or
1900 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1902 * symfile.h: New file, defining the interface between the
1903 generic and object-file-specific symbol reading code.
1905 * symtab.c: Move generic symbol-reading interface to symtab.c,
1906 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1907 table to map BFD targets to symbol-reading modules in GDB.
1908 Change index to strchr.
1909 (lookup_struct_elt_type): Use error() rather than hand-made
1910 simulations thereof.
1911 (lookup_partial_symbol): Speedup slightly when length == 0.
1912 (symbol_file_add): New function.
1913 (symbol_file_command): Call it.
1914 (symfile_open, symfile_init): New function.
1915 (add_file_target_command, add_file_addr_command): moved from
1918 * target.c (target_command): use target_kill.
1920 * target.h (target_files_info): Don't declare, never called
1923 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1924 files to determine stack end address.
1926 * valarith.c (value_x_binop, value_x_unop): Change error message
1927 to be more useful. Pass proper argument to value_struct_elt.
1929 * valops.c (value_assign): FIXME comment that long long
1930 bitfields will break here.
1932 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1933 Update `make saber_gdb' to work better.
1935 * TODO: A woman's work is never done.
1937 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1938 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1939 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1940 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1941 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1942 valops.c, valprint.c, exec.c: Lint.
1945 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1947 Continuing Intel 960 port merge of GDB.
1949 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1950 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1951 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1952 Wack over "make depend" so it handles files in subdirectories
1953 vx-share, nindy-share, bfd, and in the current directory.
1955 * blockframe.c (get_prev_frame_info): Remove fatal error
1956 if stack not defined.
1958 * core.c (core_open, core_detach): New functions that handle
1959 the old "core-file" command as "target core" and "detach" instead.
1960 (core_file_command): Call them.
1961 (core_xfer_memory): Use common routine xfer_memory.
1963 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
1964 dbxread now uses bfd for everything but symbol reading itself.
1965 BFD internals are used to drag out the relevant file offsets.
1966 (partial_symbol_file_open): Change args all around for BFD.
1968 * symtab.c: Rename "value" to "val" everywhere, so we can
1970 (symbol_file_command): New command, moved from dbxread.c
1971 and coffread.c. It uses BFD to read the file, then vectors
1972 based on its type, to dbx or coff symbol readers.
1973 * symtab.h: Extern a few vars for symbol_file_command.
1975 * target.h: Breakpoint takes a char * save area, not a char **.
1977 * valprint.c (val_print): When unpacking bitfields, offset
1978 the address in gdb of the value, if it is declared with a shorter
1979 type. Remove the last "runtime kludge test" of host byte order.
1981 * utils.c: Remove old my_bfd_read routine.
1983 * stack.c (frame_info): Use target_has_stack. Print program counter
1984 register's actual name rather than "pc", since it's called the
1985 "ip" (instruction pointer) on the i960 (sigh).
1987 * target.c (target_command): Add command for selecting a target
1988 type and calling its open routine. This is used for initiating
1989 communication with a particular target, in a generic way.
1991 * tm-i960.h: Update for modern gdb. Remove semicolons from
1992 various macros. Handle reading struct return convention, and
1993 error-out attempts to return structs with the "return" command.
1994 Be sure gdb doesn't think we know how to call functions in the
1997 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
1998 to i960_xxx in lower case.
1999 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2000 not being defined yet.
2002 * remote.c (remote_open): Call start_remote to initialize
2003 wait_for_inferior during open.
2004 (remote_xfer_inferior_memory): Return length written rather
2007 * remote-vx.c (target_command -> vx_open): Use new generic
2009 * remote-eb.c, inftarg.c, exec.c: ditto.

2013 (wait_for_inferior): Clear saved register values before target_wait,
2014 so target_wait can set some of them if convenient.
2016 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2017 Return success indicator, not void.
2018 (child_xfer_memory): Avoid fetching initial word if we'll
2019 overwrite it anyway.

2049 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2050 Add magic numbers for 960 COFF format.
2052 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

2075 Fri Apr 20 13:47:15 PDT 1990
2078 Thu Apr 19 09:54:28 PDT 1990
2079 Add 'reset' command.
2081 Wed Apr 18 09:48:07 PDT 1990
2082 After opening remote tty, wait for 1 second to go by without input
2083 from it before trying to talk to NINDY (fixes problems with the
2084 Heurikon HK80/V960E).
2086 Mon Apr 4 16:33:05 PDT 1990
2087 Some output was not being suppressed in 'batch' mode.
2089 Thu Mar 22 15:31:11 PST 1990
2090 Ask user if old symbol table should be deleted when new file is
2093 Allow user to run a program downloaded before gdb960 was brought up.
2095 Correct "exec-file" help message for i80960 context.

2128 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2129 - made disassembly interface identical to that in gdmp960.
2133 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2135 * target.h: Allow targets to stack. Add target_has_memory,
2136 _registers, etc. Restructure memory access and "info files"
2137 to walk the target stack.
2138 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2139 target.c: Change tables to match target.h.
2140 * inflow.c (child_mourn_inferior): pop child_ops.
2141 (generic_mourn_inferior): Use new has_stack flag.

2143 * inftarg.c (child_files_info): New "info files" regime.
2144 * remote-eb.c: New memory regime, new info files.
2145 * remote-vx.c: New memory regime, new info files. Now use
2146 separate targets for VxWorks attachment to machine, and
2147 actually running a process under VxWorks, since one has
2148 stack & execution & regs and the other doesn't.
2149 * remote.c: New memory regime, new info files.
2150 * sparc-xdep.c (fetch_core-registers): New memory regime.
2151 * target.c: New routines and support for stacked targets,
2152 new memory regime, new info files regime.
2155 Generalize section handling for an arbitrary number of sections,
2156 including use of the new BFD (binary file) library.
2157 * gdbcore.h: Add struct section_table.
2158 * exec.c (build_section_table): Iterate all sections and
2159 record what gdb needs to know about them.
2160 (exec_command): Use it.
2161 (exec_xfer_memory): Use the table.
2162 (exec_files_info): Print the table.
2163 * core.c (core_file_command, core_xfer_memory, core_files_info):

2166 * dbxread.c: Quick changes to make it compile with new BFD.
2167 * utils.c (error): Avoid using bfd_error in generic routines.

2171 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2173 * inferior.h (attach_flag): Export.
2174 * infcmd.c (run_command): use new target_create_inferior.
2175 * infrun.c (child_create_inferior): Don't return result.
2176 * Makefile.dist (VERSION): 3.91.4.

2180 * breakpoint.c (bpstat_num): Handle breakpoints which have
2181 since been deleted, such as temporary breakpoints.
2182 infcmd.c (program_info): ditto.
2184 * core.c (core_file_command): Display the frame where the core
2189 * remote-vx.c (target_command): Merge in target command from
2190 targ-vx.c. A few other cleanups.
2192 * TODO, Projects: Lots more stuff to do...
2194 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2196 Massive changes to wall off the remote-debugging interface
2197 behind a function vector. The port to handle VxWorks targets
2198 is also part of this.
2200 All files: Replace references to renamed functions,
2201 remove references to remote_debugging, remove references to
2202 have_include_file, have_core_file in favor of target_has_stack,
2203 target_has_memory, etc.
2205 * Modularize the breakpoint interface.
2206 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2207 a breakpoint instruction.
2208 breakpoint.c: struct breakpoint's shadow_contents now sized as
2210 (insert_breakpoints): Vector to target to install breakpoints.
2211 (remove_breakpoints): Vector to target here too.
2212 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2213 sparc-tdep.c (single_step): Use new breakpoint interface for
2214 the single-step breakpoints.
2215 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2216 New file, contains routines to insert and remove breakpoints by
2217 reading out the old contents and later replacing them. This is
2218 how ptrace breakpoints work, and many remote systems as well.
2220 * tm-vxworks68.h: New config file, overrides a few things for
2221 Wind River's preferences.
2223 * target.h: New file, for transfer vector used to talk to the
2224 inferior (child, attached, core, exec, remote, etc). All accesses
2225 to the thing being debugged should come through these vectors.
2226 target.c: New file, routines to handle transfer vector.
2227 (various files): Add transfer vectors XXX_ops for the various
2228 targets and pseudo-targets (core files, etc) we support.
2230 * breakpoint.c (bpstat_stop_status): Further explorations of
2231 watchpoints and why things don't work all the time.
2232 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2234 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2235 the local gdbinit if it doesn't already have it.
2237 * core.c (core_ops): add and install.
2238 Allow core debugging without exec file.
2240 * dbxread.c (free_and_init_header_files): Merge two fns.
2241 (end_symtab): Free named symbol table when a new version comes in.
2242 (read_dbx_symtab): Relocate all kinds of symbols with base
2243 address. First step toward handling different text, data, bss
2245 (add_file_addr_command): Renamed add_file_command.
2246 (add_file_command): Vector to remote handler.
2247 Add "load" as an alias for "add-file" command.
2249 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2250 non-returning functions.
2252 * exec.c: Add exec_ops, and push it as a target when an exec
2255 * infcmd.c (run_command): Pass executable file name and arg list
2256 separately when starting an inferior. Permit "run" when no exec
2257 file is specified, for VxWorks.
2258 (detach_command): Move to child_detach in inftarg.c.
2260 * inftarg.c: New file. Unix-child-specific routines, and the
2261 child_ops structure.
2263 * inferior.h (registers): Export "registers" as the way for
2264 target dependent register handlers to find gdb's local copy of
2265 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2266 since it is now used by places that want wait_for_inferior to
2267 handle the grunge but want to see every trap from the inferior.
2269 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2270 Eliminate remote_debugging hooks in terminal handling.
2272 * infrun.c: Replace start_inferior with child_create_inferior.
2273 Move all the hair of Unix shells and ptrace idiosyncracies into
2274 child_create_inferior, so remote handlers don't have to deal.
2275 Remove running_in_shell. Rename stop_after_attach to
2276 stop_soon_quietly, and use it in a few other places where we want
2277 to just call wait_for_inferior and get control back on the first
2278 trap. trap_expected now never takes a value > 1.
2279 (init_wait_for_inferior): Initialize static vars when a new
2282 main.c (gdbinit): Add new hook for .gdbinit file name, let
2283 it be overridden by config files as GDBINIT_FILENAME.
2284 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2285 Both of these are used for VxWorks gdb.
2287 mcheck.c: rename include file "gmalloc.c" to avoid problems
2288 with system include file "malloc.c".
2290 param-no-tm.h: New include file, same as param.h but does not
2291 include the default "tm.h" file. This is used in files where
2292 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2294 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2296 remote-vx.c: New file, VxWorks remote debugging support. Uses
2297 RPC routines that are shared with the target system, in directory
2300 remote.c: Vectorize remote interface.
2302 source.c: Globalize source_path, and make an alias "l" for "list"
2303 since we now have the "load" command.
2305 sparc-xdep.c: Use new param-no-tm.h.
2307 symmisc.c (free_named_symtab): Add new function from Wind River.
2308 However, ifdef it out for now while we think about what it should
2311 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2313 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2314 non-Unix-children handle this with their own code in the target
2317 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2318 source and target lists. Add vx-share to default list of include
2319 directories. Add new files to src and target lists: mem-break,
2320 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2321 ${srcdir} versions of munch and createtags are used.
2323 * valops.c (find_function_addr): Split out of call_function.
2324 (call_function_by_hand): Rename call_function; this function
2325 calls functions in the target by laboriously patching the target
2326 word-by-word with the right stack, args, regs, etc.
2329 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2331 Handle AMD 29000 a bit better.
2333 * remote-eb.c (readchar): Mask received char log to make it readable.
2334 (remote_start): Pass arguments down to executing program.
2335 Make startaddr unsigned.
2336 infrun.c (start_inferior): Accept args, pass them to
2338 infcmd.c (run_command): Pass args down to start_inferior.
2340 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2341 the target object file format.
2342 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2344 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2345 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2347 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2349 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2350 * TODO: We did a few things, we have more to do though.
2352 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2353 * inflow.c (inferior_died): Clear deferred stores.
2355 * Debug problems with dummy frames and calls to the inferior.
2356 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2357 * sparc-tdep.c (do_restore_insn): Simplify.
2358 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2359 (sparc_push_dummy_frame): Simplify and fix what we push.
2360 (sparc_pop_frame): Slightly more hair here, deciding whether
2361 we are restoring a saved PC or returning to a return address in %i7.
2362 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2364 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2365 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2366 * obstack.h (chunkfun): ditto.
2367 * defs.h (xmalloc, xrealloc): ditto
2369 * utils.c (quit): Grab the terminal from the child if necessary.
2371 * inflow.c (term_status_command): Rename to term_info, change
2374 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2375 (is_delayed_branch): Speed up.
2376 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2377 Still missing some float ops, and needs testing.
2379 * Support for input and output radixes other than base 10
2380 * defs.h (input_radix, output_radix): Declare.
2381 * expread.y (yyparse, parse_number): Handle changes of input
2382 radix, and ambiguous names-or-numbers in radixes >10.
2383 * printcmd.c (print_scalar_formatted): Print formatted hex
2384 numbers in varying column widths.
2385 * valprint.c (val_print): Use output_format to print scalar ints.
2386 (set_input_radix, set_output_radix, set_radix): Create.
2387 (set_output_radix): Set output_format from output_radix.
2388 (_initialize_valprint): add `set radix' but leave the others off.
2390 * main.c (execute_command): Let stupid questions be turned off.
2391 (_initialize_main): Handle "set stupidity", etc.
2393 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2394 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2396 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2398 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2399 bfd stuff is still screwed up, but with some manual work, it
2402 * breakpoint.c (bpstat_do_actions): Start over if a command
2403 proceeds the inferior, since the inferior will have stopped and
2404 will need to have its new stop-actions taken care of.
2406 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2407 compiler fits, simplify it.
2409 * gdb.texinfo (directory command): Doc new dir command.
2410 source.c (directory_command): "dir" now puts things on the front
2411 of the path, moves dups up front, and handles multiple names
2412 on the command line, inserting each one in order. It also
2413 blows away cached line and full_filename info.
2415 * stack.c (backtrace_command): Skip "more stack frames follow"
2418 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2419 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2420 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2421 The only odd one was Gould NP1, which had defined vprintf to
2425 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2426 variable, inspect_it.
2427 valprint.c (print_string, val_print): Use the global inspect_it
2428 to indicate whether to print in Epoch style or normal style.
2430 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2432 * printcmd.c (call_command): add an alias for the "print" command
2433 which runs expressions and doesn't print the result if void.
2434 (print_command_1): implement it.
2436 * command.c: Remove #if 0'd code. Initialize all the fields
2437 in add_cmd (). Rename do_nothing_command to
2438 not_just_help_class_command, and make it externally visible.
2439 command.h: add user_commands to struct.
2440 * main.c (define_command): Don't overload c->function with a char
2441 string as well as a function pointer.
2443 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2444 calling convention of value_struct_elt () that got dropped in
2447 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2448 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2450 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2452 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2453 until a good time (e.g. when we are about to run the child),
2454 saving ptrace calls.
2455 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2456 * tm-sparc.h: define DO_DEFERRED_STORES.
2458 * sparc-xdep.c (store_inferior_registers): when storing float
2459 registers, don't store stack regs too. When storing the SP,
2460 however, DO store the stack regs too. This fixes a bug in which
2461 the dummy frame is not recognized when a call_function finishes,
2462 because its frame pointer (in the stack regs) was never
2464 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2465 even though we don't know how to read them from an inferior.
2466 valops.c (call_function): Comment about storing SP.
2468 * infrun.c (save_inferior_status): Save away the original bpstat
2469 chain so it can be restored later. Install the copied version for
2470 use by whoever saved the status. It will be blow away by
2471 restore_inferior_status, and the original chain restored. This is
2472 important for people who have pointers into the original.
2474 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2475 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2476 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2479 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2481 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2482 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2483 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2485 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2487 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2488 Store the baseclasses in a type struct starting from array element
2489 0 rather than from the unusual array element 1.
2491 dbxread.c: the above.
2492 (virtual_context): Add
2493 Read new debug information about which virtual function table
2494 a virtual function is from, and store it in fn_field.fcontext.
2496 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2497 TYPE_FN_FIELD_STATIC_P.
2499 symtab.c: the above.
2500 valops.c: the above. Handle pointer casts of object *'s.
2501 (search_struct_method): Add.
2502 (value_struct_elt): First arg is now a pointer to a value, and is
2505 valprint.c: the above.
2506 values.c (value_virtual_fn_field): Add type arg. Handle
2507 offsetting to the proper object when calling virtual fns.
2509 (baseclass_addr): Add valuep arg.
2511 * README: Document the current state of BFD config (missing).
2512 * TODO, ChangeLog, Makefile.dist: Roll version.
2513 * WHATS.NEW: Add summary of changes since 3.5.
2515 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2517 * dbxread.c (read_struct_type): Clear bit vectors whenever
2519 symtab.c (B_CLRALL): define.
2521 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2522 using == rather than =. Huh... This fixes the dreaded problem
2523 wherein builtin_type_int becomes TYPE_CODE_FLT.
2525 * core.c (info_files): Show the inferior pid.
2527 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2528 already knows how to look in the source directory.
2530 * Remove psymtab hair from many places. Remove duplicated code
2531 for searching symbol tables. Hide psymtabs from most places.
2532 Make it fast to get from a psymtab to its symtab.
2534 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2535 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2536 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2537 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2538 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2539 new symtab completely. New psymtabs get symtab pointer
2540 initialized to zero. Remove MI warning printf.
2541 symtab.h: Comments. Add psymtab to symtab pointer.
2542 (PSYMTAB_TO_SYMTAB): New macro.
2543 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2544 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2546 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2548 (print_frame_info): Avoid special-casing symbols that have not yet
2551 * source.c (open_source_file): Quick path if we have already
2552 located the source file by its full name.
2554 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2555 find_pc_psymtab. When a name is found in the misc function
2556 vector, search the symbol table for its mangled name, not the
2557 name that the user typed.
2559 * bfd.h: Fix missing comment terminators, make #endifs match.
2561 * valarith.c (value_less): Handle unsigned int comparisons.
2562 Add FIXME about pointer compares, which assume host and target
2563 pointers are the same.
2565 * command.c (do_nothing_command): lint
2566 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2567 fix comments on debug symbol format for visibility. Actually set
2568 visibility of symbols.
2569 main.c (echo_command): lint; use <readline/history.h>.
2570 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2571 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2572 pointing past end of allocated memory; saber complains.
2573 obstack.h: Declare the external functions that we use.
2574 valarith.h: use <string.h>
2575 solib.c (solib_add): lint.
2577 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2579 * main.c (initialize_main): Default info_verbose to off, now that
2580 symbol reading is fast.
2581 (quit_command): Avoid clobbering exec_bfd while quitting.
2583 * Initial BFD (binary file diddling library) merger:
2584 coffread.c: Change AOUTHDR to struct exe_hdr.
2586 core.c: initialize initialized data at compile time.
2587 (core_file_command): Move from coredep.c, convert to bfd.
2588 (xfer_core_file): Convert to bfd.
2589 exec.c (exec_file_command): use bfd routines.
2591 mips-tdep.c: Remove exec_file_command and friends.
2594 * coredep.c: (fetch_core_registers) Convert core_file_command to
2595 fetch_core_registers.
2596 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2598 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2599 (my_bfd_read): More bogosity, which I don't think we call.
2600 (program_name): Remove this atrocity asap!
2602 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2605 values.c: allocate_repeat_value was not clearing the
2606 optimized_out field.
2607 (value_static_field): minor stylistic fix (wrong macro was used).
2608 valops.c (value_struct_elt_for_address): didn't work for C++
2611 * signame.c (_initialize_signame): Initialize signal names once.
2613 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2614 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2615 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2617 * remote-eb.c: Support user-settable baud rates on the serial port.
2619 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2621 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2623 * tconfig/sun3os4: Remove warning about native assembler,
2624 since it also occurs in the xconfig file.
2626 * findvar.c (registers): Allocate some slop after `registers'
2627 to prevent stray accesses from trashing the next variable.
2629 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2630 on the sun-3, by changing the #ifdef from `sun3' (which is not
2631 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2632 vars, which happened to follow `registers' in the executable.
2634 * readline/history.c (history_search): Heed gcc-2's advice
2635 and parenthesize && inside ||).
2637 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2638 tm-29k.c: Insert FSF copyright headers.
2640 * remote-eb.c: Better comments.
2642 * Makefile.dist: Update to 3.91.6.
2643 * TODO: note PREPARE_TO_STORE problem.
2645 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2647 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2649 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2651 * infrun.c (wait_for_inferior, at end): Don't set up
2652 prev_* if the inferior no longer exists.
2654 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2655 CANNOT_EXECUTE_STACK.
2656 valops.c (call_function): Use it.
2658 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2660 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2661 infrun.c (wait_for_inferior, 2 places): Use it.
2663 * values.c (value_being_returned): Only use
2664 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2666 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2667 right thing for remote-eb.c.
2669 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2670 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2672 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2673 (FRAME_FIND_SAVED_REGS).
2675 * findvar.c ({fetch,store}_registers): Check for
2676 REMOTE_{FETCH_STORE}_REGISTER macro.
2678 * findvar.c (get_saved_register): Add argument lval and
2679 change meaning of argument addr.
2680 findvar.c: Change calls to get_saved_register to reflect
2681 new calling convention.
2682 valops.c (value_assign): Use get_saved_register instead of
2683 find_saved_register.
2685 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2687 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2688 an (uninitialized) pointer to one. Use "&" when passing it
2691 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2693 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2696 * coffread.c (symbol_file_command): Put semicolon after
2698 Put safe_to_init_tdesc_context in #if defined (TDESC).
2699 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2700 coffread.c: #include <sys/stat.h>.
2701 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2702 Add missing ')' in check for "lc%" and friends. Remove
2704 Declare read_one_sym() at top of file.
2705 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2706 MC68WRMAGIC can have the same value without causing a duplicate
2709 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2711 * Allow a Makefile to be built without building the
2712 tm and xm file links that screw up builds in subdirectories.
2713 This is done with `config.gdb none', then you can do things
2714 like `make gdb.tar.Z'.
2715 * tconfig/none: Config file for no target system
2716 * xconfig/none: Config file for no host system
2717 * config.gdb: If no TM or XM files are called out by the
2718 host or target file, don't make links for them.
2720 * cplus-dem.c: Add documentation.
2722 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2723 simple error, so the user's gdb doesn't crash due to some object
2724 file problem (e.g. somebody is rebuilding the file out from under
2727 * printcmd.c (print_address_symbolic): demangle the symbol.
2729 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2730 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2731 (alldeps.mak): sort and uniq all results from this; duplicates
2732 hose gdb.tar.Z link building. Remove RCS files from
2733 tconfig and xconfig. Add config files for sun386. Add
2734 a few odd files to OTHERS and HFILES.
2736 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2738 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2739 Roll version number to 3.91.5. Make lint work in bindir.
2741 * README: Document cross-debugging and new file structure.
2743 * blockframe.c: Lint. Include "value.h" to declare read_register.
2744 (find_pc_partial_function): remove duplicate line.
2746 * command.h: Lint. Declare error_no_arg and dont_repeat.
2748 * tm-news.h: Remove inadvertently duplicated stuff.
2750 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2751 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2753 * config.gdb: Allow `config.gdb host target' form. Clean
2754 up previous change that printed bogus messages when you just said
2757 * core.c: #include "command.h" for lint.
2760 * main.c: Remove some casts of enums. Lint.
2767 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2769 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2770 read it from memory. This will allow us to save ptrace calls
2771 eventually. Changed caller single_step too.
2773 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2774 that we aren't going to use, saving many ptrace calls, especially
2775 when watchpointing or single stepping. Use some #define's for
2777 (store_inferior_registers): Ditto.
2778 (core_file_command): Use some #define's for constants.
2780 * tm-sparc.h: Add #define's for some register numbers, so we
2781 can eliminate the use of random constants in sparc-xdep.c.
2783 * stack.c (frame_command, print_frame_info, up_command,
2784 down_command) Remove frame_changed, since it
2785 causes a bug and doesn't seem to do anything useful. In some
2786 places it was used as a flag, in others as a stack level (?).
2788 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2789 default is to use the portable (vprintf) version rather than the
2791 * xm-news.h (MISSING_VPRINTF): Add.
2793 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2795 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2797 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2798 about linking debugged programs -Bstatic in the sun?os4 config
2799 files in tconfig and xconfig subdirectories.
2801 * main.c (main): Remove unreached exit(0) now that we exit
2804 * Create TODO file for online bug list. There are too many
2805 "little" bugs to keep track of on paper.
2808 rather than kingdon@ai.
2810 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2812 * Makefile.dist (VERSION): 3.91.4 now.
2814 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2815 (condense_misc_bunches): Add sanity check that misc_count is
2816 the same as the number of symbols in the bunch.
2818 * coffread.c: rename init_misc_bunches. Pass an argument
2819 to condense_misc_bunches (a zero).
2821 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2822 every time we are called; don't rely on our caller to do it.
2823 (add_file): Remove call to init_misc_bunches.
2825 * mipsread.c: Only warn, don't error, if unknown symbol types.
2826 This keeps an old gdb from falling on its face if it sees newly
2827 extended symbol info. Rename init_misc_bunches.
2829 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2831 * Merge in changes from Per Bothner for DECstations and other
2832 MIPS stuff. The rest is Bothner speaking:
2834 The next message is a merger of Alessando Forin's mips port with
2835 mine. I've tried to use my good if biased judgment to get
2836 the best of both. It *does* need testing.
2838 Some of the changes are general, *not* mips-specific.
2841 Didn't believe in little-endian bit order.
2842 There are still inconsistencies about whether flags
2843 like BITS_BIG_ENDIAN are integer (#if ...) or
2844 boolean (#ifdef ...). I tried to paper over them.
2846 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2847 Moved some misc_function code that was common to
2848 {dbx,coff,mips}read.c to symtab.c.
2849 In the process, I think I cleaned things up a bit.
2850 At the same time, moved obsavestring and obconcat to symtab.c.
2853 Removed obsolete condense_addl_misc_bunches (use
2854 condense_misc_bunches(1) instead).
2857 Needed to include <sys/dir>, at least on DECstations.
2859 valops.c, mips-tdep.c, tm-mips.h:
2860 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2861 conventions (when STACK_ALIGN is insufficient).
2862 Needed on mips, where doubles need 8-byte alignment,
2863 but ints only need 4.
2866 Removed cruft that was not being used.
2870 Print $ before register-names (I think that makes things a little
2872 Never print two instructions, even if one delays.
2873 Removed hex-disassemble set_cmd. (This is not mips-specific,
2874 so I think the argument is whether it is generally worthwhile or not.
2875 I'm inclined to think not, given how easy it is to
2876 convert between radixes in gdb.)
2879 This is basically Alessando's code.
2880 It doesn't use obstacks; I changed it to use obstacks
2881 in a few minor places where using malloc causes a
2882 memory leak. (Probably, more places could/should be changed.)
2883 I added record_misc_function where it was missing.
2884 In symbol_file_command and add_file_command, I tried
2885 to make the code consistent with more recent versions.
2886 Minor sylistic changes in parse_procedure.
2887 Make a .gdbinfo. psuedo-symbol point back to the real
2888 procedure symbol (using the isym field).
2891 This is basically from my port, but with a lot of details
2892 and a number of routines merged in from Alessando's version.
2893 I basically used my code "raw" backtrace (use heuristics
2894 from the actual code, rather than symbol table info) - though
2895 the idea is Alessandro's. I feel my code is a little cleaner
2896 here, particularly in being a little more flexible, such as being
2897 able to handle gcc-produced code (which it now can).
2898 It also doesn't do frame caching (which is not useful
2899 more recent gdb versions).
2900 I also used my code for push_/pop_dummy, more or less.
2901 I tried to incorporate AF's code for testing sigtramp
2902 while backtracing; I probably got it wrong.
2903 Added mips_print_register, which tries to scrunch as much
2904 information as possible on a screen...
2905 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2906 under mips-pinsn.c), I don't see anything mips-specific here,
2907 and I don't see it being all that useful anyway.
2910 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2911 Use more register names (rather than hard-cases numbers).
2913 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2915 * Hack up 3.90.11 changes:
2917 * Makefile.dist (depend): parameterize $(GCC).
2918 Add solib.c and solib.o.
2919 (readline): Fix vpath for both absolute or relative SRCDIR.
2922 Also, let the part I didn't understand at least compile so
2923 I can test the rest. FIXME.
2925 * dbxread.c: Fix thinko using strcmp.
2926 (init_psymbol_list): declare static.
2927 (partial_symbol_file_open): Comment cleanups better, avoid
2928 cleaning up the string table since the caller will do that.
2929 Move the stat for mod time into symbol_file_command, temporarily.
2930 (There should be a mod time for each symbol file, eventually,
2931 to control its rereading. FIXME.)
2933 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2934 SunOS, which gives error for shared libs otherwise. (From
2935 Schaefer, probably FIXME needs work for portability.)
2937 * solib.c: Move #include "param.h" to work.
2938 Lowercase all the Uppercase Letters In the Messages.
2939 (find_solib): Clean up inferior_so_name for debug printouts.
2940 Allow no argument, to mean all shared libraries.
2942 * symmisc.c: include param.h to get CLEAR_SOLIB.
2944 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
2946 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

2968 Put parens around gcc_p in expansion.
2970 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
2972 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.

2976 * Changes for Sun shared libraries:
2977 blockframe.c (find_pc_partial_function): If a non-text symbol
2978 is found, set *address = pc - FUNCTION_START_OFFSET.

2980 Disable breakpoints instead of giving an error.
2981 source.c (select_source_symtab): Initialize cs_pst.

2987 (record_misc_function): Give correct type for N_DATA symbols.
2988 (condense_misc_bunches): do "misc_function_count = j" regardless
2990 Take code which is shared between symbol_file_command and
2991 add_file_command and put it into partial_symbol_file_{open,read}.
2992 Split add_file_command into add_file_command and add_file.
2993 Make psymtab_to_symtab read in the string table if the file
2995 Two new parameters to read_dbx_symtab and start_psymtab.
2996 tm-sunos.h: New file.
2998 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3000 * infcmd.c: Change cont_command to continue_command and "cont"
3003 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3005 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3007 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3009 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3010 size 1,2,4,8 rather than size < 8.
3012 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3013 as necessary, not just once.
3015 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3017 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3019 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3021 * tm-news.h: Add CALL_DUMMY_*.
3023 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3025 * config.gdb: In list_host, list_target, use ${i}, not $i.
3027 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3029 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3031 * sparc-opcode.h: Change all store floating-point state register
3032 instructions to have the right match & lose fields.
3034 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3036 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3038 config.gdb: If srcdir != ., create readline directory and
3039 copy a makefile into it.
3041 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3042 consistency with POSIX.
3044 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3045 when we exit its exp_valid_block.
3047 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3049 * Makefile.dist: Bump version to 3.91.3.
3051 * Clean up handling of breakpoint commands (somewhat).
3052 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3054 inferior.h: Add breakpoint_proceeded to inferior status struct
3055 and globals; save it and restore it.
3056 (clear_breakpoint_commands): Cleanup, remove old #define.
3058 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3059 (save_inferior_status, restore_inferior_status): handle it also.
3060 (proceed): Remove earlier code that set breakpoint_proceeded.
3061 It is now set only in clear_proceed_status.
3062 (clear_proceed_status): Cleanup, use bpstat_clear rather
3063 than clear_breakpoint_commands. No callers need the stop_bpstat
3064 between clear_proceed_status and proceed.
3066 infcmd.c: Add breakpoint_proceeded definition and comment.
3067 (cont_command, jump_command, signal_command): Move call to
3068 clear_proceed_status right next to call to proceed.
3070 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3071 caller's argument while running down the chain of breakpoints.
3072 Use new variable "breakpoint_proceeded" to determine when
3073 a command that it executes moves the inferior past the
3075 (bpstat_clear): Handle NULL argument.
3076 (bpstat_clear_actions): Avoid useless call to
3077 breakpoint_auto_delete.
3078 (delete_breakpoint): Clean up bpstat's that are pointing to
3079 the deleted breakpoint from the stop_bpstat chain.
3080 (breakpoint_auto_delete): Simplify.
3082 * Clean up handling of EOF, error on stdin, etc. This was
3083 prompted by a network problem that caused gdb to go into an
3084 infinite loop filling up its malloc'd memory.
3086 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3087 not clear_breakpoints_commands, which is now gone.
3088 (main): If command_loop returns (e.g. from EOF on stdin), do
3089 a quit_command (looping back to command_loop if quit_command
3090 doesn't really quit).
3091 (command_loop): check result from command_line_input and
3092 exit if it returns NULL, rather than passing the NULL to
3094 (gdb_readline): Free malloc'd result space before returning
3097 * utils.c (query): Handle C-d to mean "yes", just as if the
3098 input was not a terminal. Also avoid infinite loop if EOF
3099 occurs in mid-input-line before newline. This allows
3100 query to be used at EOF on stdin with reasonable results.
3102 * infrun.c (proceed): Set breakpoint_proceeded.
3104 * values.c (value_as_long): Avoid infinite recursion for enums.
3105 (_initialize_values): Fix typo in help msg (kingdon).
3107 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3108 RL_LIB for linking. This allows -lreadline for linking
3109 and nothing for dependencies, once readline is a real library.
3111 * config.gdb: Jim Kingdon: give useful error message if the
3112 host or target type is not recognized.
3114 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3115 it just defines it. Dumb, but deal with it.
3117 * Jim Kingdon suggests:
3118 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3120 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3122 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3124 * Clean up Bothner's changes.
3126 * blockframe.c (clear_pc_function_cache): New function.
3127 * blockframe.c: remake cache_pc_function_* static.
3128 * dbxread.c (symbol_file_command): remove references to
3129 cache_pc_function_* variables.
3130 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3131 * printcmd.c: Avoid kludging a global variable (addressprint)
3132 to avoid printing the address of a string twice. Instead,
3133 pass the format letter 's' down low enough that it can be seen
3134 to avoid this problem.
3135 (print_formatted): Pass format arg to value_print.
3136 (restore_addressprint): Remove function.
3137 (do_examine): Avoid hacking addressprint, cleanups and such.
3138 (print_frame_args): Add a comment to a Bothner change.
3139 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3140 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3141 to wipe out the values cached in blockframe.c.
3142 * symtab.c (find_method): Add comment saying how big you must
3143 allocate to be "big enough". Per being terse again.
3144 * valprint.c (val_print): Handle format letter "s" to print
3145 strings without addresses. Add comment to vtbl printing code
3146 which casts with wild abandon. Rearrange reference-printing
3148 @0xaddr: value (print w/addressprint)
3149 value (print w/~addressprint)
3150 @0xaddr (parameter lists w/addressprint)
3151 or nothing (parameter lists w/o addressprint)
3153 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3155 * Merge more changes from Per Bothner:
3157 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3158 annoying) that I tried to improve it. Here are my suggestions.
3160 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3163 Do automatic de-reference when taking the address of a reference.
3165 Don't deref_ref when printing parameter lists.
3167 More attempts at treating refernences properly.
3169 In val_print, if deref_ref==0, don't print dangling " = ".
3171 Add COERCE_REF macro, which de-references an REF.
3173 * Merge changes from Per Bothner:
3175 * Fixed (Sony news)-specific configuration problems.
3176 * Fixed other problems with using vanilla pcc and libc (enum problems;
3177 assumption that vsprintf exists).
3178 * Some major speed-ups (finc_pc_partial_function now caches a match;
3179 parsing avoids duplicate symbol_lookup calls).
3180 * Changed handling of baseclasses (no longer use baseclasses field
3181 of struct type, use the first n_baseclasses fields instead).
3182 * Various minor changes/fixes, most C++-related.
3185 Cache the most previous match from find_pc_partial_function.
3186 (Save both low and high ends of matching function's pc range.)
3187 This speeds up the loop of infrun.c:wait_for_inferior quite
3188 a bit, and makes step/next commands much zippier.
3190 Added an enum->int cast (otherwise, some compilers barf).
3192 No longer set baseclass offset to 0, since multiple
3193 inheritance now mostly works.
3194 Added a number of casts, to shut up compiler warnings
3195 (after stabs where made enums, not ints).
3196 When discarding a symbol table (in symbol_file_command),
3197 must clear the cache introduced in blockframe.c.
3198 Don't convert $vtbl_ptr_type to vtbl any more.
3199 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3200 Mask off sign bit emitted by g++ for virtual table offset.
3201 Set voffset to -1 (not 1) for static member functions.
3203 Changed parsing/lexing of names to avoid doing symbol lookup twice
3204 (once when lexing to determine symbol class, once for real).
3205 Now only call symbol_lookup once. Fields of 'this' win especially big.
3207 Subpress printing addr twice in the case of 'x/s addr'.
3209 lookup_basetype_type is no longer used.
3210 Add find_methods as recursive helper function to decode_line_1.
3211 This allows multiple inheritance to work.
3212 Also, once one or more matches has been found, do not look in
3213 base-classes. (Baseclass methods would be overridden, anyway.)
3215 Removed baseclasses array in struct type.
3216 Instead of using baseclasses[i], use fields[i-1].
3217 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3218 Changed sign convention of voffset (previous was inconsistent).
3220 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3222 Used to assume existence of vsprintf. Re-written to not need it
3223 if HAVE_VPRINTF is undefined.
3225 typecmp was too pessimistic. Made it less so.
3227 Don't print space after address.
3228 If vtable points to a misc symbol (with 0 offset), print it,
3229 since that indicates the actual class of the object.
3230 Changed ype_print_derivation_info to use new inheritance
3231 scheme (without baseclasses vector).
3233 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3234 Also, changes needed because TYPE_BASECLASSES were removed.
3236 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3238 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3241 If there is no path set, and the symbols don't indicate what directory
3242 a file was compiled in, look in the current directory. But either
3243 a path or a known compilation directory will prevent this.
3246 Three independent bug fixes:
3247 * Remove the #if 0 block that breaks some stuff.
3248 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3249 adapt gdb to either SunOS 4.0.* or 4.1.
3250 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3253 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3256 (type_print) Demangle the name being printed.
3257 (type_print_base) Handle botched demangling without coredump (tiemann).
3260 (check_stub_method): Document routine.
3261 (tiemann) fix bug for no-arg functions
3262 Avoid clobbering beyond end of malloc'd storage.
3263 Terminate the argument list properly.
3267 * Changes merged by John Gilmore:
3270 In breakpoint_1, use new print_address_symbolic instead
3271 of find_pc_partial_function. (This forces use of assembler-level
3272 addresses, and avoids misleading non-mangled source-level names.)
3274 Generalize ansi argument such that -1 means skip arglist totally.
3275 Removed global variable print_ansi_qualifiers (which made
3276 code non-reentrant), in favor of extra explicit arguments
3277 to internal routines.
3279 Add new helper function print_address_symbolic.
3280 Use find_pc_misc_function instead of find_pc_partial_function
3281 (since we want assembler-level symbols here).
3283 Print unknown function as just "f (...)", not "f (...) (...)".
3284 Use new fputs_demangled explicitly.
3286 Fixed a typing violation (problem: value.h cannot be imported
3287 without renaming many variable in this file).
3288 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3289 decode_line_1: Moved forward some never-reached code.
3290 Made decode_line_2 skip function prologues correctly.
3292 fputs_filtered should not demangle by default.
3293 Add new fputs_demangled to demangle on demand..
3295 Change value_struct_elt to use value_primitive_field (using recursive
3296 utility function search_struct_field). This allows foo.bar to work
3297 for multiple inheritance (so far only for data fields).
3298 Change check_field in the same way (recursive helper function
3299 to support multiple inheritance).
3300 (Note: there are more of these problems that I haven't fixed.
3301 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3302 value_of_this: 'this' symbol name is now just "this", note "$this".
3304 Don't print static members.
3305 Avoid printing "members of <type>" if there are none.
3306 Simplified type_print_derivation_info by merging duplicate code.
3307 Remove useless blank lines in type_print_base (ptype command).
3309 Added declaration of new routine value_primitive_field.
3311 Added value_primitive_field which is generalized version of
3312 value_field that can handle multiple inheritance (non-zero offsets etc).
3313 Re-implemented value_field to call value_primitive_field.
3315 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3317 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3318 delete the whole environment. Karl Berry reported the bug.
3319 * source.c - fix openp to avoid //'s in filenames, which
3320 trigger an Emacs bug causing it to not be able to find files
3321 when running gdb in a window.
3322 * dbxread.c - zap the #if 0 that botches the add-file code.
3323 It seems to work a lot better without all the code commented out.
3325 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3327 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3330 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3332 * Makefile - added a ${CFLAGS} to a couple of entries,
3333 added remote-sa.sparc.c
3334 * added remote.sa-sparc.c, a modification of remote.c
3335 which conducts a dialog directly with the SparcStation prom.
3336 * breakpoint.c, infrun.c, sparcdep.c added
3337 remote_insert_breakpoint(), and remote_remove_breakpoint()
3338 to breakpoint.c instead of directly writing breakpoint instructions.
3339 * sparcdep.c on remote_debugging,there is no need
3340 to remove signle step breakpoint instructions.
3341 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3343 * printcmd.c - epoch interface sends lisp expressions to open up
3344 epoch windows on inspection.
3345 * valprint.c - added arrayprint, and addressprint and made adding
3346 format controls easier
3347 * wait.h added a couple of undef's because we were getting
3348 complaints about WSTOPSIG and WTERMSIG begin redefined.
3351 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3353 * symtab.c (decode_line_1): Add support for handling method stubs
3354 in the type information.

3358 * values.c (baseclass_addr): Run loop from INDEX+1 to
3359 N_BASECLASSES; otherwise, we can still get into a loop.
3360 @@ This should be restructured to use a cleaner search strategy.
3362 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3364 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3365 abbreviation "Tt" for tags which have the same name as their
3368 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3370 * symtab.c (list_symbols): add ability to set breakpoints on all
3371 the functions which match a particular regular expression.
3373 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3375 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3376 should print ANSI qualifiers (such as `const' and `volatile').
3377 All callers changed to call with ANSI == 1, except from
3378 `check_method_stub', which uses old-style syntax.
3380 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3381 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3383 * values.c (check_stub_method): New function.
3385 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3387 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3388 * valprint (type_print_base): Ditto.
3390 * symtab.c (gdb_mangle_typename): New function.
3392 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3394 * breakpoint.c (catch_command): New function. Provides a
3395 mechanism to set breakpoints based on catch clauses.
3396 (disable_catch): Similar, but disables breakpoints on catch
3398 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3400 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3402 * blockframe.c (blockvector_for_pc): New function.
3403 * blockframe.c (block_for_pc): Changed to call
3404 `blockvector_for_pc' and get the block itself.
3406 * stack.c (catch_info): New function. Prints info about
3407 exceptions which can be caught in the current frame.
3408 * stack.c (print_frame_label_vars): New function. Similar to
3409 `print_frame_local_vars'.
3410 * stack.c (print_block_frame_labels): Prints out labels that are
3411 defined in this frame. These labels are exceptions that can be
3414 * dbxread.c: Updated to handle N_CATCH symtab types.
3416 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3418 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3419 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3420 when printing the type.
3422 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3424 * valprint.c (val_print): Use `baseclass_addr' to access the
3425 baseclasses pointed to via the derived class object at VALADDR.
3427 * values.c (baseclass_addr): New function. Casts derived pointers
3428 to baseclass pointers taking virtual baseclasses and multiple
3429 inheritance into account.
3431 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3435 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3437 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3438 exp_valid_block field correctly.
3440 * infrun.c (wait_for_inferior): When checking "don't even think
3441 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3442 also check step_resume_breakpoint.
3443 Insert breakpoints and continue (not step) if
3444 step_resume_break_address != NULL, even if another_trap.
3445 If trap_expected and we enter sigtramp, then set up a
3447 If trap_expected is set when we hit the step_resume_break,
3449 When calling resume and trap_expected says tell resume to step
3450 (2 places), also check step_resume_break_address.

3461 Restore old code which distinguishes between trap_expected and
3462 running_in_shell, just make the latter take any non-TRAP signal,
3465 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3467 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3468 xconfig/3b1 (CC,PINSN_CC): Define.

3494 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3495 instead of stuffing things in buffers (oappend, etc).
3497 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3498 execute_command, exit both loops.

3568 (enter_linenos): Use it.
3569 * blockframe.c: Add INIT_FRAME_PC hook and use it in
3570 get_prev_frame_info.
3571 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
3572 Use dummy versions of FRAME_CHAIN_*.
