183 been read in, particularly for VxWorks.
185 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back

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

218 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
220 * m68k-stub.c: Remote stub for 680x0's, created from
221 rem-m68k.shar (which is removed).

223 Remove RCS log stuff now that we use CVS and it blows our diffs.
225 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
227 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

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

247 new psymtab for it has been read.
248 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
249 a file, once a new symtab has been read for it.
250 * mipsread.c: FIXME. We need to do the same for MIPS, but it
251 looks harder to determine the top-level block before it's been
252 queued to the psymtab list.
254 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
255 If we have wiped out any old symbol tables, clean up at end of
257 (symbol_file_command): Don't reference symfile_fns if it's zero.
259 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
260 defines for the blocks of a blockvector that contain global and
261 file-static symbols and the first of the smaller scope contours.
262 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
263 decode_line_1, make_symbol_completion_list): Use the above.

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

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

683 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
684 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
685 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
686 double_to_ieee_extended.
687 * i960-tdep.c: Define ext_format_i960.
688 * m68k-tdep.c: Define ext_format_68881.
689 * sparc-tdep.c: Define ext_format_sparc, though unused.
690 * Makefile.dist (HFILES): Add ieee-float.h.
691 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
694 Obsolete the "coffstrip" program in favor of using BFD's strip.
696 * nindy-share/coffstrip.c: Remove file.
697 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
698 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
699 * tconfig/nindy960: Remove reference to coffstrip.o.
701 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
703 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
705 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
706 * dbxread.c: Remove static symfile_bfd.
707 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
709 * inftarg.c (child_detach): Pop the child_ops vector if the
710 detach is successful.
711 * remote-nindy.c (nindy_create_inferior): Don't push a new
712 nindy_ops since nindy uses the same one for execution and memory
714 * core.c (core_ops): Use child_attach and child_create_inferior
715 rather than default attach and create_inferior functions.
717 Handle floating point registers in core files.
719 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
720 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
721 This version untested since BFD doesn't yet support sun3 core
723 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
724 conventions. Fix comments and style. This version has not
725 been compiled yet, since we have no HP inhouse.
726 * core.c (get_core_registers): Look for two sections, ".reg"
727 and ".reg2", and pass both to fetch_core_registers sequentially.
729 Revise directory path yet again.
731 * source.c (forget_cached_source_info): Not static any more.
732 (init_source_path): New default source path is "$cdir:$cwd".
733 (dir_command): Handle variable arguments ($cdir, $cwd).
734 (source_info): Print "Compilation directory" rather than
735 "Originally compiled in" to remind people of $cdir.
736 (openp): If the path contains $cwd, use current directory.
737 (open_source_file): If compilation directory is known, replace
738 first $cdir in path with the compilation directory.
739 (print_source_lines): Even if we can't print the lines, set the
740 current symtab and line for future commands like "info source" or
741 "breakpoint". Also, error message now contains the file name,
742 line number, and file access error message.
743 (_initialize_source): Fix help text to describe changes.
744 * main.c (cd_command): Forget cached source info when we chdir.
745 * utils.c (strstr): Add simple implementation.
747 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
749 * coffread.c (read_one_sym, init_linetable, init_stringtab):
750 Byte-swap COFF symbol tables if necessary when reading them in.
751 Use complain() to replace error message in one spot. Needs
752 corresponding change in bfd/coff-code.h to make some symbol
753 swapping routines non-static.
755 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
757 Merge changes from Eirik Fuller, for UTek.

762 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
763 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
764 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
765 declarations of errno.
767 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
769 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
770 <rpc/rpc.h> and <rpc/types.h>.
772 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
774 * i960-tdep.c (examine_prologue): Add new argument limit,
775 which stops the scan at the end of the prologue, or at the PC.
776 This fixes a problem where it walks down into the code for the
777 user's statements if that code looks like function prologues.
778 Mark Fox and I have been bouncing this code back and forth, making
779 small changes to it. Callers changed to match.
781 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
783 Cleanup for gdb-3.94 release final:
785 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
786 the .c files from vx-share and nindy-share, from the various
787 macros, since they are not found via ALLDEPFILES.
788 (SFILES): Add tm-i960.h.
789 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
790 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
792 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
793 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
795 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
797 * am29k-tdep.c: Add contribution line.
798 (examine_prologue): Cache information about function prologues in
799 the misc-function-vector to avoid lots of references over the
800 serial line while examining instructions.
802 * core.c (core_close): New function made from cleanup_core.
804 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
805 remote-vx.c, remote.c, target.c, target.h,
806 Update target_ops vector to add attach, close, and load entries.
807 Use add_syms_addr_command, not add_file_addr_command, for
808 add_file. Break out close routine from existing code.
810 * dbxread.c (really_free_pendings): Don't free pending_blocks;
811 they are in an obstack.
812 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
814 (define_symbol): Add symbol type parameter; change callers;
815 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
816 it to influence the symbol class on the i960.
817 (define_symbol): Swap LOC_CONST's into target byte order.
819 * exec.c (exec_close): New function.
820 (exec_file_command): Call it.
822 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
823 Fix byte order of frame pointer.
824 (read_var_value): Result of 0 if var's value can't be found,
825 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
826 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
827 (locate_var_value): Use read_var_value and use its lazy address
828 as the location of the var's value. Lint.
830 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
833 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
834 obsolete Intel versions in favor of vxgdb versions.
835 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
836 code dealing with byte order of values, which Intel did in host byte
837 order rather than gdb-4's target byte order.
838 (i960_frame_chain_valid): Move to nindy-tdep.c.
839 (examine_prologue, skip_prologue, frame_find_saved_regs,
840 frame_args_address, leafproc_return, saved_pc_after_call,
841 pop_frame): Add vxgdb versions from Mark Fox.
842 (examine_prologue, frame_struct_result_address): Add code
843 to deal with the saved value of G13 (struct return address
845 (frame_args_address): Modify Mark's version to prefer the
846 saved value over the current value in the topmost frame.
847 Cache result in the frame info to avoid performance hair in
849 (print_fault): Add gdb960 code for printing faults.
850 (_initialize_i960): Actually call check_host.
852 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
853 add stub routines. FIXME, these currently just return zero!
855 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
856 (attach_command): Call target_attach, not target_open, now.
858 * infrun.c (normal_stop): Make global, not static, for vx_attach.
859 (child_attach): Rename from child_open.
860 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
861 don't confuse it with a zero step_resume_break_address.
863 * inftarg.c (child_detach): Eliminate inferior_pid test.
864 (child_files_info): Clean up message a bit.
865 (child_ops): Use child_attach, not child_open, to attach.
867 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
868 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
869 findvar.c to here, since it depends on the contents of the
870 shadow_contents of breakpoints, but keep if #if 0 since it is
873 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
876 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
877 (ptype_command, display_command): Eliminate have_inferior_p and
878 have_core_file_p in favor of target_has_stack or
879 target_has_execution.
880 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
881 code for actually finding the values of arguments, though we still
882 keep track of the maximum stack offset for use in printing unnamed
883 arguments. Handle missing FRAME_ARGS_ADDRESS.
885 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
886 (struct nindy_regs): Define registers passed to/from nindy.
887 (nindy_fetch_registers, nindy_store-registers): Translate between
888 nindy and GDB formats for the registers.
889 (dcache_init): Statically allocate the cache, since it was being
890 allocated by a malloc that was never freed anyway.
891 (nindy_create_inferior): Error, not core dump, if no exec file.
892 (nindy_before_main_loop): Use target_load, not target_add_file.
894 * remote-vx.c (net_load): Specify large timeout for load
895 requests. Allow user to break out with INTERRUPT.
896 (net_break): Remove useless code, clean up. Change callers.
897 (parse-args, skip_white_space, find_white_space): Clean up arg
898 parsing to cope with quoted strings.
899 (net_wait, net_quit): Never call error, just return status.
900 (vx_read_register, vx_write_register): Cleanup status checking.
901 #ifdef the code based on which CPU we are using (960 or 68k),
902 FIXME, this should be completely general but it isn't yet.
903 (vx_xfer_memory, vx_resume): Cleanup status checking.
904 (vx_run_files_info): Improve message.
905 (vx_load_command): Renamed from vx_add_file_command. Allow load
907 (net_ptrace): Remove unused routine.
908 (vx_wait): Adopt code from vxgdb960 to cope with broken
909 connections to target machine and prompt to disconnect. Remove
910 debug printouts. Map some EVENT_'s to SIGnals.
911 (add_symbol_stub, vx_open): Print names of object files we found,
912 and "ok" if we read their symbols OK. Clarify output in general.
913 (vx_attach, vx_detach, vx_kill): Add these commands.
914 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
915 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
916 "info files" output, and create_inferior, since we already have
919 * stack.c (frame_info): Replace Frame_unknown with 0.
920 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
921 (return_command): Pop until the PC matches as well as the FP,
922 so it works even if the FP is shared with another function,
923 as in "frameless" or "leaf" procedures.
925 * symfile.c (load_command): renamed from add_file_target_command.
926 (add_syms_addr_command): renamed from add_file_addr_command.
927 (add_syms_command): Stub to call target_add_syms.
928 (_initialize_symfile): Change command names and descriptions,
929 add-file => add-syms, and load from alias to its own command.
931 * target.c (kill_or_be_killed, maybe_kill_then_attach,
932 maybe_kill_then_create_inferior): Default for attempts to start
933 a process, if one is already running, is to ask about killing
935 (upstack_create_inferior): #if-0 it, strata obsolete it.
936 (push_target, unpush_target, pop_target): to_close() a target
937 before unstacking it.
938 (target_info): Renamed from target_files_info.
939 (_initialize_targets): Rename "i files" as "i target", accessible
942 * target.h: Improve comments about the target_ vectored routines.
944 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
945 Convert commenting style to standard GNU style.
946 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
947 (SKIP_PROLOGUE): No longer a no-op.
948 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
949 (*_REGNUM): Sort register numbers.
950 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
951 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
952 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
953 are now 10 byte extendeds, not 8 byte doubles.
954 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
955 for nindy versus vxworks targets. FIXME, this should possibly go
956 in the target vector.
957 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
958 frame_saved_regs and arg pointer with each frame.
959 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
960 (FRAME_ARGS_ADDRESS): Use cached result.
961 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
962 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
963 (PRINT_RAMDON_SIGNAL): Call print_fault.
964 (POP_FRAME): Now works.
966 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
967 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
968 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
969 (ADDITIONAL_OPTION_HANDLER): use target_load, not
972 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
973 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
975 * valarith.c (value_subscripted_rvalue): Avoid handling
976 floats and doubles specially; it gave alignment errors. Lint.
978 * valops.c (value_of_variable, value_of_this): Error if unknown
981 * valprint.c (print_floating): Bcopy rather than pointer-deref,
982 to avoid alignment problems.
983 (value_print): Handle unknown value address.
984 (cplus_val_print): Two args are ignored; remove them. Change caller.
985 (val_print): Use unpack_long rather than pointer-deref.
988 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
989 to avoid alignment problems.
990 (value_being_returned): Error if return value unknown.
991 (set_return_value): Add bogosity warning, FIXME. *
993 * TODO: A woman's work is never done.
995 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
996 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
997 Add ieee-float.o to OBS.
998 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
999 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1000 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1002 Changes to generalize the VxWorks RPC protocol slightly, to handle
1003 i960 as well as 68000.
1005 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1006 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1007 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1008 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1009 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1010 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1011 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1012 so they will move in target byte order rather than network
1013 byte order (happens to be the same).
1015 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1017 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1019 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1022 Add contribution lines to various files, showing where they
1025 * breakpoint.c (break_insn, check_break_insn_size,
1026 read_memory_nobpt): Remove to mem-break.c.
1028 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1031 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1032 entry has bad register number. This change is not
1033 tested in this release, FIXME.
1035 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1038 * value.h: Force value's contents field to be aligned to hold
1039 at least a double or a long long (if supported). This avoids
1040 doing bcopy's in and out of the contents field.
1042 (step_1): Avoid coredump under obscure circumstances when we
1045 * symtab.h (misc_info): Add field to misc function vector for
1046 any kind of cached information the target code desires. AMD
1047 29000 uses this to avoid repeating examine_function_prologue's.
1049 * coffread.c: Lint. Remove static symfile, read_section_header.
1050 core.c (have_core_file_p): Lint: remove.
1051 expprint.c (print_subexp): Lint.
1052 infptrace.c, valops.c, valprint.c: lint.
1054 Roll in changes from vxgdb-5.0.1:
1056 * symtab.h: Comment byte order of each address class. Add
1057 LOC_LOCAL_ARG for frame-relative args (960).
1058 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1059 symtab.c, symmisc.c: ditto.
1061 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1063 * remote.c (remote_resume): Error if resume with a signal.
1065 * symfile.c (prim_record_misc_function): Clear misc_info.
1066 (fill_in_vptr_fieldno): Check stub type of arg.
1068 * valops.c (value_cast): Avoid looking up names of types whose
1069 name we don't know, to prevent coredump. Sun CC produces typedef
1070 rtx and the name of *rtx is zero...
1072 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1074 Roll in changes from final AMD 29000 port (Tiemann).
1076 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1077 for ../include/a.out.encap.h. This might not work now that BFD
1078 is separately compiled. Instead, BFD support for encap will have
1079 to translate machine type 29k into the right COFF_MAGIC.
1081 * infcmd.c: Remove references to inferior_pid that aren't used
1082 in actual ptrace calls; use target_has_execution, etc.
1083 (have_inferior_p): Remove function.
1084 (program_info): Print target info rather than "process number";
1085 avoid gratuitous messages unless from_tty.
1086 (run_stack_dummy, finish_command): Set proceed_to_finish.
1087 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1088 main.c: Lint. Lose have_inferior_p().
1089 inferior.h (have_inferior_p): Remove, lint.
1090 (proceed_to_finish): Add flag to ask that all regs be saved
1091 by normal_stop, for the few commands that need it, speeding up
1092 serial I/O. Add comments to stop_registers.
1094 * remote-eb.c: Remove newline from breakpoint message we grep
1095 for. Never time out when running the user program.
1099 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1101 Roll in changes from vxgdb-5.0.1:
1103 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1104 symbol in its raw form, we are processing an unlinked ".o" file.
1105 See if the target environment has assigned it an address, using
1106 target_lookup_symbol (VxWorks does), and enter it into the symtab
1109 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1110 68k versions for a simpler version that assumes zero FP at bottom.
1111 Fixes bug of truncated stack reports.
1113 * target.h (target_lookup_symbol): Define this routine's args
1114 and result, finally.
1116 * target.c (nosymbol): Default routine for target_lookup_symbol.
1117 (target_default): Default lookup_symbol and call_function too.
1118 (files_info): Only print has_all_memory warning if a non-dummy
1121 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1122 vx_convert_from_virtual): If target does not have floating point,
1123 zero register "values", and avoid doing cross-net conversions.
1124 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1125 (vx_open): Rearrange code that attaches to target and reads
1126 symbols for all loaded modules, to work if some of the modules
1127 are not accessible. Add symbol_stub() and add_symbol_stub()
1128 as callbacks from catch_errors(). Allow connect attempt to be
1129 interrupted painlessly with ^C (FIXME, there are still some bugs
1130 if the interrupt happens during symbol reading.). Print
1131 final message with puts_filtered, since symbol messages are
1136 * main.c (catch_errors): Only print errstring if non-null.
1137 (command_loop): Avoid an ioctl per command to test ISATTY.
1139 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1140 (vx_xfer_memory): Return correct result!
1141 (vx_files_info): Indicate whether target has float or not.
1142 (vx_lookup_symbol): Complain, not error, if target gone.
1143 (vx_open): Print "Connected" msg before disabling immediate-quit.
1144 [FIXME: lookup_symbol and vx_open changes need testing.]
1146 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1147 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1148 contributor lines and update copyrights to 1991.
1150 Changes from an attempted H-PUX host port:
1152 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1153 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1154 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1155 * remote-vx.c: include <sys/time.h> for HPUX.
1156 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1157 "core_file_command" routine to BFD regime. May not work yet.
1159 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1161 * xgdb.c: Replace X10 version with some VJ version.
1162 (FIXME: Its copyright assignment is not on record.)
1163 * xgdb.c: Update include files to X11R4 (Xaw crud).
1164 (xgdb_display_source, create_text_widget): fix call to
1165 get_filename_and_charpos. Rewack source window stuff for X11R4
1166 (gleaned from include files, and "nm's" of binary libraries, since
1167 I had no doc available).
1168 (append_selection, append_selection_word): Disable with FIXME
1169 since R4 changed interface here.
1170 (create_buttons): Add back the old set of buttons.
1171 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1173 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1174 Roll VERSION to 3.94 (not yet final though).
1176 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1178 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1179 obstack_int_grow, obstack_int_grow_fast): Eliminate
1180 cast on left of assignment, which gives MIPS cc fits and is
1183 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1184 F_ALIAS. Use printf, not fprintf, when not passing a file
1186 (compare_opcodes): Check that identical instructions have
1187 identical opcodes, complain otherwise.
1189 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1190 was reported by Roland McGrath.
1191 (unimp): Only match if exactly zero instruction. (Roland)
1192 (branches and traps): Generate all variations of these
1193 instructions with macros, based on a single call that defines
1194 each condition name and its binary representation.
1195 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1197 * valprint.c (val_print_fields): Take, and use, format parameter.
1198 This means that "p/x struct" again prints the elements in the
1199 desired format. Changed callers.
1201 * stack.c (frame_info): Use filtered output, and indicate wrap
1202 points. Remove kludgy formatting designed to avoid line wrap.
1204 * utils.c (wrap_here): If the line is already full (because
1205 we had printed a long indent or long wrapped string), do an
1206 immediate newline-and-indent.
1208 * m68k-pinsn.c (print_insn_arg): Bugfix from
1209 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1210 instruction is incorrectly disassembled as bkpt #8.
1212 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1213 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1214 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1215 and then will dump core (sometimes). I traced it back to an
1216 uninitialized symfile_name in psymtab_to_symtab.
1217 (const_vol_complaint): Add quotes to message.
1218 (define_symbol): Only believe line number if gcc_compiled.
1219 Avoid allocating symbol if we will not return it.
1221 Add target strata support so that newly established targets go
1222 into their right place in the target stack (e.g. a new exec file
1223 doesn't wipe out the ability to access the running process).
1225 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1226 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1227 and initialize it properly in all the targets.
1229 * target.h: Document strata. Change return type of push_target.
1231 * target.c (nomemory): new function for dummy memory access.
1232 (tcomplain): Rename complain, now also used in symfile.c.
1233 (push_target): Push targets within strata. New return value shows
1234 whether new target is on top of stack or not. Always keep dummy
1236 (target_files_info): Ignore dummy target.
1238 * core.c (core_open): Warn user, and skip accessing file, if the
1239 core target is not the topmost target in the stack.
1240 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1243 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1244 target_ops, it doesn't belong there since we have no regs there.
1245 Change name of target from machine => memory to clarify.
1247 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1249 * Freeze version 3.93 for release.
1251 * Makefile.dist: Handle vx-share and nindy-share subdirs
1252 properly when building gdb.tar.Z.
1254 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1255 printed in various places, so I could change just one copy.
1257 * dbxread.c, coffread.c: Change references to bfd->iostream
1258 to cast to FILE *, now that BFD avoids needing types defined
1259 in other header files.
1261 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1263 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1264 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1265 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1266 (actually gcc -Wall).
1268 * dbxread.c: Remove first_global_sym, last_global_sym, since
1269 they are never referenced.
1271 * defs.h (baud_rate): Declare.
1272 main.c: Define it, and add the -b option to set it.
1274 * gdb-int.texinfo: Add text on how to define a new host or target
1275 architecture, prompted by Per Bothner's questions about MIPS
1278 * gdb.texinfo: Document "complaints". Change doc of -q since
1279 gdb no longer prints the copyright and blurb if you specify a file
1280 name to be debugged (just like Emacs). Add doc for Nindy-specific
1281 command line flags for specifying target serial port and such.
1282 Update copyright to 1991.
1284 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1285 has taken over for us the job of ripping up executable files. The
1286 crud caused Per Bothner's port to not compile.
1288 * infrun.c (normal_stop): Avoid printing "Program exited
1289 normally" if we are in batch mode. This allows a GDB which
1290 executes a program on a target system, to behave like a Unix
1291 command (input from stdin, output to stdout, no extraneous
1294 * main.c (main): Allow additional machine-dependent command line
1295 options to be specified with the ADDITIONAL_OPTIONS,
1296 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1297 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1298 processing to occur just before the main loop with
1299 BEFORE_MAIN_LOOP_HOOK.
1300 (main): If a "core file" argument is specified, and it is not a
1301 core file, try it as a process ID to attach.
1302 (symbol_completion_function): Attempt to cope with
1303 "show screen-" TAB, not very successfully. This needs more work,
1305 (batch_file): New function, returns whether we are reading
1306 commands from an interactive tty on stdin, or from somewhere else.
1307 Called by normal_stop since it doesn't get from_tty passed down
1308 to it like many commands do.
1310 * remote-nindy.c: Handle command line options for nindy
1312 (nindy_before_main_loop): Prompt user for tty name if they
1313 don't specify it before getting to the interactive command loop.
1315 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1316 and -r command line options. Also add hook before main loop
1317 to make it easy to specify a tty.
1319 * TODO: More things to do, one done.
1321 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1323 * dbxread.c: Make complaint() calls pass pointer, not struct.
1324 Add complaints about badly formatted C++ type information
1325 (const/volatile indicator, and parse errors resulting in
1326 error_type). Fix C++ virtual member fn comment.
1327 (read_struct_type): Avoid bumping pointer if we got a parse
1328 error; this prevents our walking beyond the end of a string.
1329 Terminate loop on null char as well as semicolon.
1330 (process_one_symbol): Fix the LBRAC fix so that it uses the
1331 last previous SLINE, FUN, or SO record's PC address. C++ debug
1332 symbols did not have SLINE records in a useful order compared
1333 to the LBRAC records.
1334 (define_symbol): Handle "catch" records.
1336 * symtab.c (check_stub_type): Added new complain
1337 `stub_noname_complain' and added a consistency check to
1338 keep the debugger from crashing when finishing from an
1339 exception frame. A real fix will be needed later.
1341 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1343 * infcmd.c (attach_command): Make global.
1345 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1346 but make them easy to comment out. Perhaps later they should
1347 be enabled by what CPU you configure for? FIXME.
1348 (VERSION): Roll to 3.93.
1349 (pinsn.o): Remove rule for obsolete file.
1350 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1352 Run down a problem that manifested by printing the wrong function
1353 name in stack traces of read_ofile_symtab. Turned out that the
1354 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1355 the LBRAC symbol with an address in the *data* segment, which
1356 blew our binary search through the blocks.
1358 * dbxread.c: Use the complain() facility consistently to bitch
1359 about problems in the symbol file we are reading.
1360 (finish_block): Add code to check the nesting of the blocks;
1361 complain and Procrust them to fit if wrong.
1362 (make_blockvector): Check the order of the blocks, complain
1363 [but don't cope] if wrong.
1364 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1365 symbols to be sure their PC value is greater than the last SLINE
1366 (line number) symbol we've seen, complaining and adopting the
1367 SLINE PC value if wrong.
1369 * symfile.h (struct complaint, complaint_root, complain,
1370 clear_complaints): Add.
1371 * symfile.c (complain, complaint_root, clear_complaints): Add
1372 facility to deal with non-fatal complaints and to regularize their
1374 (symbol_file_add): Clear complaint counters to allow new complaints.
1375 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1377 * dbxread.c (dbx_symfile_read): Remember the address and size
1378 of the string table for the main symbol file, so we won't read it
1380 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1381 to avoid reading the string table yet again. Lint.
1382 (throughout): Improve filtered output, including word wrap.
1383 (read_range_type): Improve Bothner's fix to handle other types too.
1385 * utils.c: Improve line wrap implementation. Handle unlimited
1386 width by making chars_per_line unsigned.
1387 (puts_filtered): New, easy, function.
1389 * defs.h (puts_filtered): add.
1391 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1392 call the identical sort_symtab_syms() in symfile.c instead.
1394 * expread.y: Suggest the `file' command rather than `symbol-file'.
1396 * command.h (enum var_types): Add zinteger for seroable
1398 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1399 nested if's into a switch.
1401 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1402 we did not stop because of a breakpoint (it must have been for
1403 some other reason, like a "stepi"), so don't print anything.
1405 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1406 doesn't include <sys/types.h>, old SunOS's require it for
1409 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1411 A test port of gdb-3.92.6 to the Sony NEWS.
1414 Don't normally link in remote- or vx stuff.
1415 Some of it doesn't compile, and it wastes space for 99% of the users.
1416 Remove reference to no-longer-used HAVE_VPRINTF.
1417 Fixed BFD_DEP typo to BFD_DIR.
1419 Fix cast in arg to bfd_h_getlong.
1420 Make char *prefix be const.
1421 Fix how certain range types are mapped into builtin unsigned int types.
1423 Remove 2 #includes. They cause errors (on Sony, at least),
1424 and aren't needed (they wern't in earlier versions).
1426 print_address_symbolic should never demangle labels
1427 (since it prints *assembler-level* labels).
1429 [This was superseded by the change to printcmd below.]
1432 Add some "volatile" return types to avoid warnings.
1433 If MISSING_VPRINTF add vprintf function and not just macro
1434 (since vprintf is used in printcmd.c).
1436 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1437 (The latter isn't grokked by some PCC-based compilers.)
1439 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1441 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1442 * nindy-share/coffstrip.c
1443 Added some forward declarations (otherwise, gcc complains
1444 about implicit extern redefined as static).
1446 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1448 Changes inspired by Per Bothner:
1449 * printcmd.c (print_address_symbolic): Take additional parameter
1450 specifying whether to demangle.
1451 (print_address): Pass in asm_demangle to control demangling.
1452 (print_address_demangle): New fn, takes explicit arg to control
1454 * utils.c: Add new vars demangle and asm_demangle, and let them
1456 (fputs_demangled): If !demangle, just print the argument.
1457 (fprint_symbol): If !demangle, just print raw symbol.
1458 * valprint.c (val_print): Call print_address_demangle rather than
1459 print_address, to cause demangling to depend on the global
1460 rather than assembler-level demangling setting.
1461 * WHATS.NEW, gdb.texinfo: Document.
1463 * main.c (show_command): Show all settings if no arg.
1464 (initialize_main): Make "info set" the same as naked "show".
1465 * command.c (cmd_show_list): Handle prefix commands in the
1466 list, and print the name of the setting as well as its English
1467 description and value.
1469 Allow gdb functions to specify where a line should wrap if it
1470 exceeds the size of a terminal line. Use it to make the output
1472 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1473 of the right size when screen width changes.
1474 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1475 (wrap_here): New fn, indicates a point in the output where we
1476 should wrap the line rather than just letting it overflow at a
1478 (fputs_filtered): Implement wrapping.
1479 (n_spaces): New fn, returns a pointer to N spaces.
1480 (print_spaces_filtered): Use n_spaces.
1481 * defs.h (n_spaces): Declare.
1482 * stack.c (print_frame_info): Wrap with 4-space indent after
1483 fn name and before filename and line number.
1484 * printcmd.c (print_frame_args): Wrap with 4-space indent
1485 before each argument name is printed.
1486 * valprint.c (value_print): Wrap with no indentation before
1488 (val_print_fields): Wrap with indentation relative to nesting
1489 level before each field name.
1490 (val_print): Wrap with nesting indentation before array elements.
1491 * command.c (do_setshow_command): Avoid extra newlines,
1492 wrap with 4-space indent around values printed, end with period.
1493 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1495 * breakpoint.c (breakpoint_1): Implement addressprint for
1496 "info breakpoints" display. Change file name and line number
1497 format to " at file:nnn" rather than " (file line nnn)".
1498 * gdb.texinfo: Document.
1501 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1503 Frozen for gdb-3.92.6 release.
1505 README, WHATS.NEW: Update for 3.92.6 release.
1507 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1508 coffread.o from configs since it is now built by default.
1509 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1510 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1511 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1512 from configs since it is now built by default.
1514 Makefile.dist: Update for release 3.92.6. Handle files that
1515 have been moved to ../include, ../getopt, or ../bfd. Add
1516 saber.suppress and tests directory. Add config.status to
1517 the release (it will say "none").
1519 coredep.c: Minor formatting fixes.
1521 These changes were made in early December but only checked in now:
1522 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1523 nindy-share/nindy.c: lint
1524 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1525 register values coming back from the target; we store values
1526 in target byte order everywhere.
1528 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1530 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1532 * valprint.c (cplus_val_print, val_print_fields): New functions,
1533 which print C++ objects. They conspire to avoid printing a
1534 virtual base class more than once, following all the twists and
1535 turns of C++ virtual base rules.
1536 (val_print): Call the above rather than do it by hand.
1538 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1539 symbol file, not for added files like shared libs. This really
1540 needs to be generalized to a timestamp per file.
1542 * core.c (cleanup_core): Avoid coredump if no core file.
1544 * config.gdb: Accept -host or -target in place of +host or
1547 * coffread.c (find_linenos): Avoid desupported BFD interface
1548 to line numbers. We still read them manually rather than using
1549 BFD's "generic" features.
1551 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1553 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1555 * Makefile.dist: Eliminate use of $< in explicit targets.
1557 * readline/Makefile: Use $< rather than $*.c, which does not
1558 include the VPATH in GNU Make.
1560 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1561 copies of tconfig/i960, added for global configuration
1562 compatability. All i960 versions can read both coff and b.out.
1564 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1565 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1568 * TODO: Think of more things to do.
1570 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1572 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1573 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1574 64-bit float conversion.
1576 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1577 equivalent to sun?os4 so global config works.
1579 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1581 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1583 * main.c: Only declare linesize once; declare pagesize not at
1584 all, since it is never used.
1585 (main): Clear newly allocated line before it is used.
1587 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1589 Further stabilization for the Intel 960.
1591 * Makefile.dist: Parameterize the location of the "include"
1592 and "bfd" directories, as well as "getopt". Add symfile.c.
1593 Link in both dbxread and coffread. Fix up "make depend" to
1594 rewack the locations of include, bfd, and getopt in its output.
1596 * README: Document moving include files, improve some of
1599 * coffread.c: Move common code out to symfile.c. Change
1600 symbol_file_command style interface to use new *_symfile_init
1601 and *_symfile_read interface under BFD. Use BFD internal
1602 info to locate line table, symbols, etc.
1604 * core.c (core_fetch_registers): Rename to get_core_registers
1605 to avoid confusion with fetch_core_registers.
1606 (register_addr): Move to coredep.c, which is already machine
1607 dependent. This leaves core.c pretty clean of dependencies.
1609 * coredep.c (register_addr): Accept this routine from core.c.
1611 * dbxread.c: Move common code (with coffread.c, etc) into new
1612 symfile.c. Each psymtab now contains a pointer to the
1613 format-dependent function that knows how to read it in. Make
1615 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1616 (process_one_symbol): Add code to complain about a "compiler bug
1617 we muzzle here", if we actually see it.
1619 * eval.c (evaluate_subexp): Insert missing "break" statements
1620 in code that determines whether a variable is an lvalue in
1621 memory, register, or whatever. I detected this via a compiler
1622 bug in which it *almost* mashed out the whole switch statement.
1624 * gdb-int.texinfo: Add minor sections on configuring gdb for
1625 release, and about the README file.
1627 * infcmd.c (registers_info): Fix formatting somewhat. Still
1628 not as pretty as before, but it handles byte swapping.
1630 * remote-nindy.c: If data cache routines are interrupted while
1631 waiting for the remote end, be sure that any uninitialized cache
1632 blocks are on the free list, not on the valid list!
1634 * symfile.h: Flesh out this header file with all the various
1635 routines and variables that have been merged in from dbxread.c
1636 coffread.c, and symtab.c to symfile.c.
1638 * symfile.c: New file, containing code common to dbxread.c,
1639 coffread.c, and some code from symtab.c. All generic code for
1640 reading symbol files should be in here now.
1641 (unrecord_misc_function): Remove unused function.
1643 * symtab.h: Remove file-reading things to symfile.h.
1645 * symtab.c: Remove file-reading things to symfile.c.
1647 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1648 to decode i960 fault types.
1650 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1651 target.c: Change type of the "resume" function from int to void,
1652 since its result was never used.
1654 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1656 * main.c: Replace "stupid" with "caution"; you now "set caution
1659 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1661 * infcmd.c (do_registers_info): Call val_print to deal with the
1662 byte order of the registers being printed. FIXME, this makes
1663 the formatting of the output uglier.
1665 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1666 defined, call it for signals the debugger doesn't itself use.
1667 The i960 uses this for more detailed fault information.
1669 * remote.c (remote_open): If arg is null, print help rather than
1672 * sparc-xdep.c (register_valid): Avoid declaring size, since
1673 various modules will think of various sizes depending on the
1674 architecture of their tm-file. FIXME, we need protection against
1675 actually entering one of those modules, which would clobber
1676 storage if not for the target architecture compiled into gdb.
1678 * stack.c (up_command, down_command): Always print the frame
1680 (up_silently_command, down_silently_command): New commands
1683 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1685 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1686 more parameters than it used to.
1688 * findvar.c (registers): Increase slop to 256 bytes, which should
1689 protect us against even most RISC machines with large register
1691 (locate_var_value): Move declaration inside related ifdef.
1693 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1694 throughout, to avoid throwing away buffered input from the board.
1695 (nindy_wait): Supply_register takes addr_of_value, not value.
1696 (i960_print_fault): Renamed from i80960_fault.
1697 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1698 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1700 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1701 we can set the PC in the call to proceed(). Unpush nindy_ops
1702 before pushing it on top, to avoid message to user. Eliminate
1703 commentary from Unix machines that just misleads here.
1704 (reset_command): Fix error message to suggest target command.
1706 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1708 Release 3.92.5 as frozen.
1710 Stabilize the merged release...with help from lint, Saber C,
1713 Everywhere: Add include files needed to declare return types
1714 of functions called.
1716 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1718 * breakpoint.h: Add undeclared breakpoint functions, and some
1719 functions for display handling since I couldn't think of a better
1722 * breakpoint.c (insert_breakpoints): Make code for disabling
1723 shared library bkpts more likely to work. It's used when we
1724 rerun a program and stop before the shared library has been
1726 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1727 cast from pointer, so it squeezes through catch_errors.
1728 (bpstat_stop_status): Fix logic broken some time ago. We now
1729 always create a bpstat if the stop address matches a breakpoint,
1730 even if we don't stop there -- just like the old code used to do
1731 before I got my fingers into it (sigh).
1732 (breakpoint_1): Print "ignore count" after "stop only if"
1733 condition, since that's how it actually works.
1734 (mention): Handle watchpoints as well as breakpoints.
1735 (watch_command): use set_raw_breakpoint and mention to do most
1736 of the work (and initialize all the fields!). Only pass one
1737 arg to parse_c_expression, since that's all it takes.
1739 * command.c (not_just_help_class_command): Rename arg to args
1740 since we ignore "unused argument" warnings on vars named "args".
1741 inflow.c (child_terminal_info): ditto.
1742 infptrace.c (kill_inferior): ditto
1743 main.c (catch_errors, version_info, quit_command, pwd_command,
1744 source_command, dump_me_command, editing_info,
1745 set_history_size_command, set_history, show_history,
1747 stack.c (locals_info): ditto
1748 target.c (target_files_info): ditto
1749 valprint.c (set_input_radix, set_output_radix): ditto
1751 * core.c: Remove old variables for handling core and exec file
1752 sections (data_start, data_end, stack_start, stack_end,
1753 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1754 text_end, exec_data_start, exec_data_end, text_offset,
1755 exec_data_offset, data_offset, stack_offset). They're
1756 superseded the more general build_section_table and
1758 (get_exec_file): Mention the `file' command.
1759 (read_memory_check): Rename to memory_error, and only call it
1760 in the case of an actual error.
1761 (read_memory, write_memory): call memory_error.
1762 (core_fetch_registers): Register section name is ".reg".
1764 coredep.c: Remove a bunch of crud now that all this file does
1765 is pull the registers out of a core file.
1766 (fetch_core_registers): Rewrite to actually work, I hope.
1768 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1769 Replace index() with strchr(). Remove all the pre-BFD macro
1770 definitions for accessing the symbol file.
1771 (struct dbx_symfile_info): Encapsulate the information that
1772 dbx_symfile_init needs to pass to dbx_symfile_read in this
1775 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1776 dbx_symfile_discard): Rearrange symbol file reading to divide
1777 the format-specific part from the format-independent part,
1778 leaving the format-independent part such as file name expansion
1779 and opening in symtab.c. This replaces
1780 partial_symbol_file_open and partial_symbol_file_read.
1781 Symbol_file_read, add_file, add_file_target_command,
1782 add_file_addr_command move to symtab.c. Pass an explicit
1783 "mainline" flag for when reading the main symbol table, rather
1784 than relying on the offset address to be zero or nonzero.
1786 (dbx_symfile_read): Don't allow void *'s to be printed as
1788 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1789 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1790 macro" debug version really work.
1791 (read_dbx_symtab): Remove unref'd parameter inclink.
1792 Avoid swapping N_SLINE symbols, for speed.
1793 Merge N_TEXT!N_EXT case with the other external symbol
1794 definitions' case. Add comments.
1795 (start_psymtab): Allocate the symfile name in the psymtab on
1796 the psymbol_obstack, rather than using the caller's storage.
1797 (end_psymtab): Only allocate a dependencies list if there are
1799 (psymtab_to_symtab_2): Use BFD when reopening file to read
1800 its symbols for real.
1801 (read_struct_type): Add FIXME comments where it needs work
1803 (read_huge_number): Add FIXME about overflows.
1804 (read_range_type): Add FIXME about comparing a long to 1<<32.
1806 * coffread.c: Minor changes to move things closer to the new
1807 regime with symtab.c and dbxread.c Major work is still needed
1810 * exec.c (exec_file_command): Remove old variables (see core.c
1812 (xfer_memory): If memory transfer is right at the end of a
1813 section, don't lose.
1815 * findvar.c (get_saved_register): If value is in a real
1816 register, LVAL is lval_register, not lval_memory.
1818 frame.h: Declare print_sel_frame and record_selected_frame.
1820 gdb-int.texinfo: New file, for GDB internals documentation.
1821 Very simple, unformatted doc of cleanups is there for now.
1823 gdbcore.h: Remove obsolete variables that described a.out
1824 section addresses and offsets. (See core.c above.)
1825 Declare fetch_core_registers and registers_fetched.
1827 getopt.c: Declare char *alloca(); even on SPARC.
1829 infcmd.c (run_command): Call target_kill rather than
1831 (step_command, next_command, stepi_command, nexti_command):
1832 Declare from_tty parameter even though we don't use it.
1833 (run_stack_dummy): argument BUFFER is a char array, not
1834 a pointer to REGISTER_TYPE.
1835 (finish_command): using_struct_return needed a value *,
1836 not a struct symbol *.
1838 * infptrace.c (child_xfer_memory): To avoid dependency on
1839 where sections are in memory, try PT_WRITE_D and if that fails,
1840 try PT_WRITE_I. Most Unixes don't care which you use.
1842 * infrun.c (step_resume_break_shadow): Change to array to
1843 match other breakpoint shadow storage.
1844 (clear_proceed_status): Pass address of bpstat to
1845 bpstat_clear, not the bpstat itself.
1846 (child_create_inferior): FIXME comment about if the child
1848 (start_inferior): Remove old function.
1849 (child_open): Use target_kill rather than kill_inferior.
1850 (wait_for_inferior): Ditto.
1851 (insert_step_breakpoint, remote_step_breakpoint): Use
1852 new step_resume_break_shadow.
1854 * inftarg.c (child_wait): If all child processes die,
1855 pretend that the one being waited for exited with signal 42.
1857 * main.c (command_line_input): When scanning for comments,
1858 don't coredump on unclosed quotes.
1859 (quit_command): Use target_kill rther than kill_inferior.
1860 (_initialize_main): Rename class_user from "user" to
1863 * printcmd.c (print_command_1): Initialize "fmt" if no format
1864 is specified by the user.
1865 (print_frame_args): Only add to args_printed if we are
1866 actually fetching args from the stack (avoiding undefined
1868 (_initialize_printcmd): Remove bogus \{ from string.
1870 * remote-eb.c (eb_open): Avoid coredump on no argument.
1872 * remote-nindy.c: Bring out of Intel environment into new
1873 target environment. Remove all conditional compilation on
1874 I80960. Massive hacking throughout.
1875 (nindy_xfer_inferior_memory): New routine stolen from
1877 (nindy_create_inferior): New routine pieced together, probably
1878 not quite working yet.
1879 (nindy_ops): New target_ops struct for nindy.
1881 * remote-vx.c: Use write_memory rather than target_write_memory
1882 to get error checking.
1883 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1885 (vx_create_inferior): Use target_terminal_ours...
1887 * signame.c (_initialize_signame): Always initialize, since
1888 we need the table for things other than psignal.
1890 * solib.c (solib_add): Use symbol_file_add, not add_file.
1891 (solib_address): Return boolean result rather than struct
1892 pointer which nobody else knows the type of.
1894 * sparc-tdep.c, valops.c: Use write_memory rather than
1895 target_write_memory, to get error checking.
1897 * stack.c (locals_info, catch_info, args_info,
1898 get_selected_block, frame_command, up_command): Use
1899 target_has_stack, rather than have_inferior_p or
1902 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1904 * symfile.h: New file, defining the interface between the
1905 generic and object-file-specific symbol reading code.
1907 * symtab.c: Move generic symbol-reading interface to symtab.c,
1908 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1909 table to map BFD targets to symbol-reading modules in GDB.
1910 Change index to strchr.
1911 (lookup_struct_elt_type): Use error() rather than hand-made
1912 simulations thereof.
1913 (lookup_partial_symbol): Speedup slightly when length == 0.
1914 (symbol_file_add): New function.
1915 (symbol_file_command): Call it.
1916 (symfile_open, symfile_init): New function.
1917 (add_file_target_command, add_file_addr_command): moved from
1920 * target.c (target_command): use target_kill.
1922 * target.h (target_files_info): Don't declare, never called
1925 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1926 files to determine stack end address.
1928 * valarith.c (value_x_binop, value_x_unop): Change error message
1929 to be more useful. Pass proper argument to value_struct_elt.
1931 * valops.c (value_assign): FIXME comment that long long
1932 bitfields will break here.
1934 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1935 Update `make saber_gdb' to work better.
1937 * TODO: A woman's work is never done.
1939 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1940 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1941 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1942 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1943 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1944 valops.c, valprint.c, exec.c: Lint.
1947 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1949 Continuing Intel 960 port merge of GDB.
1951 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1952 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1953 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1954 Wack over "make depend" so it handles files in subdirectories
1955 vx-share, nindy-share, bfd, and in the current directory.
1957 * blockframe.c (get_prev_frame_info): Remove fatal error
1958 if stack not defined.
1960 * core.c (core_open, core_detach): New functions that handle
1961 the old "core-file" command as "target core" and "detach" instead.
1962 (core_file_command): Call them.
1963 (core_xfer_memory): Use common routine xfer_memory.
1965 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
1966 dbxread now uses bfd for everything but symbol reading itself.
1967 BFD internals are used to drag out the relevant file offsets.
1968 (partial_symbol_file_open): Change args all around for BFD.
1970 * symtab.c: Rename "value" to "val" everywhere, so we can
1972 (symbol_file_command): New command, moved from dbxread.c
1973 and coffread.c. It uses BFD to read the file, then vectors
1974 based on its type, to dbx or coff symbol readers.
1975 * symtab.h: Extern a few vars for symbol_file_command.
1977 * target.h: Breakpoint takes a char * save area, not a char **.
1979 * valprint.c (val_print): When unpacking bitfields, offset
1980 the address in gdb of the value, if it is declared with a shorter
1981 type. Remove the last "runtime kludge test" of host byte order.
1983 * utils.c: Remove old my_bfd_read routine.
1985 * stack.c (frame_info): Use target_has_stack. Print program counter
1986 register's actual name rather than "pc", since it's called the
1987 "ip" (instruction pointer) on the i960 (sigh).
1989 * target.c (target_command): Add command for selecting a target
1990 type and calling its open routine. This is used for initiating
1991 communication with a particular target, in a generic way.
1993 * tm-i960.h: Update for modern gdb. Remove semicolons from
1994 various macros. Handle reading struct return convention, and
1995 error-out attempts to return structs with the "return" command.
1996 Be sure gdb doesn't think we know how to call functions in the

2018 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2019 Return success indicator, not void.
2020 (child_xfer_memory): Avoid fetching initial word if we'll

2080 Thu Apr 19 09:54:28 PDT 1990
2081 Add 'reset' command.
2083 Wed Apr 18 09:48:07 PDT 1990
2084 After opening remote tty, wait for 1 second to go by without input
2085 from it before trying to talk to NINDY (fixes problems with the
2086 Heurikon HK80/V960E).
2088 Mon Apr 4 16:33:05 PDT 1990
2089 Some output was not being suppressed in 'batch' mode.
2091 Thu Mar 22 15:31:11 PST 1990
2092 Ask user if old symbol table should be deleted when new file is

2131 - made disassembly interface identical to that in gdmp960.
2135 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2137 * target.h: Allow targets to stack. Add target_has_memory,
2138 _registers, etc. Restructure memory access and "info files"
2139 to walk the target stack.
2140 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2141 target.c: Change tables to match target.h.
2142 * inflow.c (child_mourn_inferior): pop child_ops.

2146 * remote-eb.c: New memory regime, new info files.
2147 * remote-vx.c: New memory regime, new info files. Now use
2148 separate targets for VxWorks attachment to machine, and
2149 actually running a process under VxWorks, since one has
2150 stack & execution & regs and the other doesn't.
2151 * remote.c: New memory regime, new info files.
2152 * sparc-xdep.c (fetch_core-registers): New memory regime.
2153 * target.c: New routines and support for stacked targets,
2154 new memory regime, new info files regime.

2186 * core.c (core_file_command): Display the frame where the core
2191 * remote-vx.c (target_command): Merge in target command from
2192 targ-vx.c. A few other cleanups.
2194 * TODO, Projects: Lots more stuff to do...
2196 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2198 Massive changes to wall off the remote-debugging interface
2199 behind a function vector. The port to handle VxWorks targets
2200 is also part of this.
2202 All files: Replace references to renamed functions,
2203 remove references to remote_debugging, remove references to
2204 have_include_file, have_core_file in favor of target_has_stack,
2205 target_has_memory, etc.
2207 * Modularize the breakpoint interface.
2208 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2209 a breakpoint instruction.
2210 breakpoint.c: struct breakpoint's shadow_contents now sized as
2212 (insert_breakpoints): Vector to target to install breakpoints.
2213 (remove_breakpoints): Vector to target here too.
2214 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2215 sparc-tdep.c (single_step): Use new breakpoint interface for
2216 the single-step breakpoints.
2217 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2218 New file, contains routines to insert and remove breakpoints by
2219 reading out the old contents and later replacing them. This is
2220 how ptrace breakpoints work, and many remote systems as well.
2222 * tm-vxworks68.h: New config file, overrides a few things for
2223 Wind River's preferences.
2225 * target.h: New file, for transfer vector used to talk to the
2226 inferior (child, attached, core, exec, remote, etc). All accesses
2227 to the thing being debugged should come through these vectors.
2228 target.c: New file, routines to handle transfer vector.
2229 (various files): Add transfer vectors XXX_ops for the various
2230 targets and pseudo-targets (core files, etc) we support.
2232 * breakpoint.c (bpstat_stop_status): Further explorations of
2233 watchpoints and why things don't work all the time.
2234 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2236 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2237 the local gdbinit if it doesn't already have it.
2239 * core.c (core_ops): add and install.
2240 Allow core debugging without exec file.
2242 * dbxread.c (free_and_init_header_files): Merge two fns.
2243 (end_symtab): Free named symbol table when a new version comes in.
2244 (read_dbx_symtab): Relocate all kinds of symbols with base
2245 address. First step toward handling different text, data, bss
2247 (add_file_addr_command): Renamed add_file_command.
2248 (add_file_command): Vector to remote handler.
2249 Add "load" as an alias for "add-file" command.
2251 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2252 non-returning functions.
2254 * exec.c: Add exec_ops, and push it as a target when an exec
2257 * infcmd.c (run_command): Pass executable file name and arg list
2258 separately when starting an inferior. Permit "run" when no exec
2259 file is specified, for VxWorks.
2260 (detach_command): Move to child_detach in inftarg.c.
2262 * inftarg.c: New file. Unix-child-specific routines, and the
2263 child_ops structure.
2265 * inferior.h (registers): Export "registers" as the way for
2266 target dependent register handlers to find gdb's local copy of
2267 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2268 since it is now used by places that want wait_for_inferior to
2269 handle the grunge but want to see every trap from the inferior.
2271 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2272 Eliminate remote_debugging hooks in terminal handling.
2274 * infrun.c: Replace start_inferior with child_create_inferior.
2275 Move all the hair of Unix shells and ptrace idiosyncracies into
2276 child_create_inferior, so remote handlers don't have to deal.
2277 Remove running_in_shell. Rename stop_after_attach to
2278 stop_soon_quietly, and use it in a few other places where we want
2279 to just call wait_for_inferior and get control back on the first
2280 trap. trap_expected now never takes a value > 1.
2281 (init_wait_for_inferior): Initialize static vars when a new
2284 main.c (gdbinit): Add new hook for .gdbinit file name, let
2285 it be overridden by config files as GDBINIT_FILENAME.
2286 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2287 Both of these are used for VxWorks gdb.
2289 mcheck.c: rename include file "gmalloc.c" to avoid problems
2290 with system include file "malloc.c".
2292 param-no-tm.h: New include file, same as param.h but does not
2293 include the default "tm.h" file. This is used in files where
2294 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2296 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2298 remote-vx.c: New file, VxWorks remote debugging support. Uses
2299 RPC routines that are shared with the target system, in directory
2302 remote.c: Vectorize remote interface.
2304 source.c: Globalize source_path, and make an alias "l" for "list"
2305 since we now have the "load" command.
2307 sparc-xdep.c: Use new param-no-tm.h.
2309 symmisc.c (free_named_symtab): Add new function from Wind River.
2310 However, ifdef it out for now while we think about what it should
2313 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2315 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2316 non-Unix-children handle this with their own code in the target
2319 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2320 source and target lists. Add vx-share to default list of include
2321 directories. Add new files to src and target lists: mem-break,
2322 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2323 ${srcdir} versions of munch and createtags are used.
2325 * valops.c (find_function_addr): Split out of call_function.
2326 (call_function_by_hand): Rename call_function; this function
2327 calls functions in the target by laboriously patching the target
2328 word-by-word with the right stack, args, regs, etc.
2331 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2333 Handle AMD 29000 a bit better.
2335 * remote-eb.c (readchar): Mask received char log to make it readable.
2336 (remote_start): Pass arguments down to executing program.
2337 Make startaddr unsigned.
2338 infrun.c (start_inferior): Accept args, pass them to
2340 infcmd.c (run_command): Pass args down to start_inferior.
2342 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2343 the target object file format.
2344 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2346 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2347 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2349 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2351 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2352 * TODO: We did a few things, we have more to do though.
2354 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2355 * inflow.c (inferior_died): Clear deferred stores.
2357 * Debug problems with dummy frames and calls to the inferior.

2360 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2361 (sparc_push_dummy_frame): Simplify and fix what we push.
2362 (sparc_pop_frame): Slightly more hair here, deciding whether
2363 we are restoring a saved PC or returning to a return address in %i7.
2364 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2366 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2367 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2368 * obstack.h (chunkfun): ditto.
2369 * defs.h (xmalloc, xrealloc): ditto
2371 * utils.c (quit): Grab the terminal from the child if necessary.
2373 * inflow.c (term_status_command): Rename to term_info, change
2376 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2377 (is_delayed_branch): Speed up.
2378 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2379 Still missing some float ops, and needs testing.
2381 * Support for input and output radixes other than base 10
2382 * defs.h (input_radix, output_radix): Declare.
2383 * expread.y (yyparse, parse_number): Handle changes of input
2384 radix, and ambiguous names-or-numbers in radixes >10.
2385 * printcmd.c (print_scalar_formatted): Print formatted hex
2386 numbers in varying column widths.
2387 * valprint.c (val_print): Use output_format to print scalar ints.
2388 (set_input_radix, set_output_radix, set_radix): Create.
2389 (set_output_radix): Set output_format from output_radix.
2390 (_initialize_valprint): add `set radix' but leave the others off.
2392 * main.c (execute_command): Let stupid questions be turned off.
2393 (_initialize_main): Handle "set stupidity", etc.
2395 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2396 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2398 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2400 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2401 bfd stuff is still screwed up, but with some manual work, it
2404 * breakpoint.c (bpstat_do_actions): Start over if a command
2405 proceeds the inferior, since the inferior will have stopped and
2406 will need to have its new stop-actions taken care of.
2408 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2409 compiler fits, simplify it.
2411 * gdb.texinfo (directory command): Doc new dir command.
2412 source.c (directory_command): "dir" now puts things on the front
2413 of the path, moves dups up front, and handles multiple names
2414 on the command line, inserting each one in order. It also
2415 blows away cached line and full_filename info.
2417 * stack.c (backtrace_command): Skip "more stack frames follow"
2420 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2421 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2422 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2423 The only odd one was Gould NP1, which had defined vprintf to
2426 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2427 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2428 variable, inspect_it.
2429 valprint.c (print_string, val_print): Use the global inspect_it
2430 to indicate whether to print in Epoch style or normal style.
2432 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2434 * printcmd.c (call_command): add an alias for the "print" command
2435 which runs expressions and doesn't print the result if void.
2436 (print_command_1): implement it.
2438 * command.c: Remove #if 0'd code. Initialize all the fields
2439 in add_cmd (). Rename do_nothing_command to
2440 not_just_help_class_command, and make it externally visible.
2441 command.h: add user_commands to struct.
2442 * main.c (define_command): Don't overload c->function with a char
2443 string as well as a function pointer.
2445 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2446 calling convention of value_struct_elt () that got dropped in
2449 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2450 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2452 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2454 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2455 until a good time (e.g. when we are about to run the child),
2456 saving ptrace calls.
2457 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2458 * tm-sparc.h: define DO_DEFERRED_STORES.
2460 * sparc-xdep.c (store_inferior_registers): when storing float
2461 registers, don't store stack regs too. When storing the SP,
2462 however, DO store the stack regs too. This fixes a bug in which
2463 the dummy frame is not recognized when a call_function finishes,
2464 because its frame pointer (in the stack regs) was never
2466 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2467 even though we don't know how to read them from an inferior.
2468 valops.c (call_function): Comment about storing SP.
2470 * infrun.c (save_inferior_status): Save away the original bpstat
2471 chain so it can be restored later. Install the copied version for
2472 use by whoever saved the status. It will be blow away by
2473 restore_inferior_status, and the original chain restored. This is
2474 important for people who have pointers into the original.
2476 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2477 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2478 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2481 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2483 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2484 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2485 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2487 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2489 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2490 Store the baseclasses in a type struct starting from array element
2491 0 rather than from the unusual array element 1.
2493 dbxread.c: the above.
2494 (virtual_context): Add
2495 Read new debug information about which virtual function table
2496 a virtual function is from, and store it in fn_field.fcontext.
2498 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2499 TYPE_FN_FIELD_STATIC_P.
2501 symtab.c: the above.
2502 valops.c: the above. Handle pointer casts of object *'s.
2503 (search_struct_method): Add.
2504 (value_struct_elt): First arg is now a pointer to a value, and is
2507 valprint.c: the above.
2508 values.c (value_virtual_fn_field): Add type arg. Handle
2509 offsetting to the proper object when calling virtual fns.
2511 (baseclass_addr): Add valuep arg.
2513 * README: Document the current state of BFD config (missing).
2514 * TODO, ChangeLog, Makefile.dist: Roll version.
2515 * WHATS.NEW: Add summary of changes since 3.5.
2517 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2519 * dbxread.c (read_struct_type): Clear bit vectors whenever
2521 symtab.c (B_CLRALL): define.
2523 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2524 using == rather than =. Huh... This fixes the dreaded problem
2525 wherein builtin_type_int becomes TYPE_CODE_FLT.
2527 * core.c (info_files): Show the inferior pid.
2529 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2530 already knows how to look in the source directory.
2532 * Remove psymtab hair from many places. Remove duplicated code
2533 for searching symbol tables. Hide psymtabs from most places.
2534 Make it fast to get from a psymtab to its symtab.
2536 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2537 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2538 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2539 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2540 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2541 new symtab completely. New psymtabs get symtab pointer
2542 initialized to zero. Remove MI warning printf.
2543 symtab.h: Comments. Add psymtab to symtab pointer.
2544 (PSYMTAB_TO_SYMTAB): New macro.
2545 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2546 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2548 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2550 (print_frame_info): Avoid special-casing symbols that have not yet
2553 * source.c (open_source_file): Quick path if we have already
2554 located the source file by its full name.
2556 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2557 find_pc_psymtab. When a name is found in the misc function
2558 vector, search the symbol table for its mangled name, not the
2559 name that the user typed.
2561 * bfd.h: Fix missing comment terminators, make #endifs match.
2563 * valarith.c (value_less): Handle unsigned int comparisons.
2564 Add FIXME about pointer compares, which assume host and target
2565 pointers are the same.
2567 * command.c (do_nothing_command): lint
2568 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2569 fix comments on debug symbol format for visibility. Actually set
2570 visibility of symbols.
2571 main.c (echo_command): lint; use <readline/history.h>.
2572 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2573 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2574 pointing past end of allocated memory; saber complains.
2575 obstack.h: Declare the external functions that we use.
2576 valarith.h: use <string.h>
2577 solib.c (solib_add): lint.
2579 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2581 * main.c (initialize_main): Default info_verbose to off, now that
2582 symbol reading is fast.
2583 (quit_command): Avoid clobbering exec_bfd while quitting.
2585 * Initial BFD (binary file diddling library) merger:
2586 coffread.c: Change AOUTHDR to struct exe_hdr.
2588 core.c: initialize initialized data at compile time.
2589 (core_file_command): Move from coredep.c, convert to bfd.
2590 (xfer_core_file): Convert to bfd.
2591 exec.c (exec_file_command): use bfd routines.
2593 mips-tdep.c: Remove exec_file_command and friends.
2596 * coredep.c: (fetch_core_registers) Convert core_file_command to
2597 fetch_core_registers.
2598 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2600 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2601 (my_bfd_read): More bogosity, which I don't think we call.
2602 (program_name): Remove this atrocity asap!
2604 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2607 values.c: allocate_repeat_value was not clearing the
2608 optimized_out field.
2609 (value_static_field): minor stylistic fix (wrong macro was used).
2610 valops.c (value_struct_elt_for_address): didn't work for C++
2613 * signame.c (_initialize_signame): Initialize signal names once.
2615 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2616 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2617 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2619 * remote-eb.c: Support user-settable baud rates on the serial port.
2621 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2623 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2625 * tconfig/sun3os4: Remove warning about native assembler,
2626 since it also occurs in the xconfig file.
2628 * findvar.c (registers): Allocate some slop after `registers'
2629 to prevent stray accesses from trashing the next variable.
2631 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2632 on the sun-3, by changing the #ifdef from `sun3' (which is not
2633 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2634 vars, which happened to follow `registers' in the executable.
2636 * readline/history.c (history_search): Heed gcc-2's advice
2637 and parenthesize && inside ||).
2639 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2640 tm-29k.c: Insert FSF copyright headers.
2642 * remote-eb.c: Better comments.
2644 * Makefile.dist: Update to 3.91.6.
2645 * TODO: note PREPARE_TO_STORE problem.
2647 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2649 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2651 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2653 * infrun.c (wait_for_inferior, at end): Don't set up
2654 prev_* if the inferior no longer exists.
2656 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2657 CANNOT_EXECUTE_STACK.
2658 valops.c (call_function): Use it.
2660 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2662 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2663 infrun.c (wait_for_inferior, 2 places): Use it.
2665 * values.c (value_being_returned): Only use
2666 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2668 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2669 right thing for remote-eb.c.
2671 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2672 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2674 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2675 (FRAME_FIND_SAVED_REGS).
2677 * findvar.c ({fetch,store}_registers): Check for
2678 REMOTE_{FETCH_STORE}_REGISTER macro.
2680 * findvar.c (get_saved_register): Add argument lval and
2681 change meaning of argument addr.
2682 findvar.c: Change calls to get_saved_register to reflect
2683 new calling convention.
2684 valops.c (value_assign): Use get_saved_register instead of
2685 find_saved_register.
2687 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2689 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2690 an (uninitialized) pointer to one. Use "&" when passing it
2693 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2695 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2698 * coffread.c (symbol_file_command): Put semicolon after
2700 Put safe_to_init_tdesc_context in #if defined (TDESC).
2701 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2702 coffread.c: #include <sys/stat.h>.
2703 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2704 Add missing ')' in check for "lc%" and friends. Remove
2706 Declare read_one_sym() at top of file.
2707 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2708 MC68WRMAGIC can have the same value without causing a duplicate
2711 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2713 * Allow a Makefile to be built without building the
2714 tm and xm file links that screw up builds in subdirectories.
2715 This is done with `config.gdb none', then you can do things
2716 like `make gdb.tar.Z'.
2717 * tconfig/none: Config file for no target system
2718 * xconfig/none: Config file for no host system
2719 * config.gdb: If no TM or XM files are called out by the
2720 host or target file, don't make links for them.
2722 * cplus-dem.c: Add documentation.
2724 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2725 simple error, so the user's gdb doesn't crash due to some object
2726 file problem (e.g. somebody is rebuilding the file out from under
2729 * printcmd.c (print_address_symbolic): demangle the symbol.
2731 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2732 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2733 (alldeps.mak): sort and uniq all results from this; duplicates
2734 hose gdb.tar.Z link building. Remove RCS files from
2735 tconfig and xconfig. Add config files for sun386. Add
2736 a few odd files to OTHERS and HFILES.
2738 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2740 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2741 Roll version number to 3.91.5. Make lint work in bindir.
2743 * README: Document cross-debugging and new file structure.
2745 * blockframe.c: Lint. Include "value.h" to declare read_register.
2746 (find_pc_partial_function): remove duplicate line.
2748 * command.h: Lint. Declare error_no_arg and dont_repeat.
2750 * tm-news.h: Remove inadvertently duplicated stuff.
2752 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2753 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2755 * config.gdb: Allow `config.gdb host target' form. Clean
2756 up previous change that printed bogus messages when you just said
2759 * core.c: #include "command.h" for lint.
2762 * main.c: Remove some casts of enums. Lint.
2769 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2771 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2772 read it from memory. This will allow us to save ptrace calls
2773 eventually. Changed caller single_step too.
2775 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2776 that we aren't going to use, saving many ptrace calls, especially
2777 when watchpointing or single stepping. Use some #define's for
2779 (store_inferior_registers): Ditto.
2780 (core_file_command): Use some #define's for constants.
2782 * tm-sparc.h: Add #define's for some register numbers, so we
2783 can eliminate the use of random constants in sparc-xdep.c.
2785 * stack.c (frame_command, print_frame_info, up_command,
2786 down_command) Remove frame_changed, since it
2787 causes a bug and doesn't seem to do anything useful. In some
2788 places it was used as a flag, in others as a stack level (?).
2790 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2791 default is to use the portable (vprintf) version rather than the
2793 * xm-news.h (MISSING_VPRINTF): Add.
2795 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2797 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2799 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2800 about linking debugged programs -Bstatic in the sun?os4 config
2801 files in tconfig and xconfig subdirectories.
2803 * main.c (main): Remove unreached exit(0) now that we exit
2806 * Create TODO file for online bug list. There are too many
2807 "little" bugs to keep track of on paper.
2809 * Change Projects file to refer to bug-gdb@cygnus.com
2810 rather than kingdon@ai.
2812 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2814 * Makefile.dist (VERSION): 3.91.4 now.
2816 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2817 (condense_misc_bunches): Add sanity check that misc_count is
2818 the same as the number of symbols in the bunch.
2820 * coffread.c: rename init_misc_bunches. Pass an argument
2821 to condense_misc_bunches (a zero).
2823 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2824 every time we are called; don't rely on our caller to do it.
2825 (add_file): Remove call to init_misc_bunches.
2827 * mipsread.c: Only warn, don't error, if unknown symbol types.
2828 This keeps an old gdb from falling on its face if it sees newly
2829 extended symbol info. Rename init_misc_bunches.
2831 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2833 * Merge in changes from Per Bothner for DECstations and other
2834 MIPS stuff. The rest is Bothner speaking:
2836 The next message is a merger of Alessando Forin's mips port with
2837 mine. I've tried to use my good if biased judgment to get
2838 the best of both. It *does* need testing.
2840 Some of the changes are general, *not* mips-specific.
2843 Didn't believe in little-endian bit order.
2844 There are still inconsistencies about whether flags
2845 like BITS_BIG_ENDIAN are integer (#if ...) or
2846 boolean (#ifdef ...). I tried to paper over them.
2848 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2849 Moved some misc_function code that was common to
2850 {dbx,coff,mips}read.c to symtab.c.
2851 In the process, I think I cleaned things up a bit.
2852 At the same time, moved obsavestring and obconcat to symtab.c.
2855 Removed obsolete condense_addl_misc_bunches (use
2856 condense_misc_bunches(1) instead).
2859 Needed to include <sys/dir>, at least on DECstations.
2861 valops.c, mips-tdep.c, tm-mips.h:
2862 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2863 conventions (when STACK_ALIGN is insufficient).
2864 Needed on mips, where doubles need 8-byte alignment,
2865 but ints only need 4.
2868 Removed cruft that was not being used.
2869 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
2872 Print $ before register-names (I think that makes things a little
2874 Never print two instructions, even if one delays.
2875 Removed hex-disassemble set_cmd. (This is not mips-specific,
2876 so I think the argument is whether it is generally worthwhile or not.
2877 I'm inclined to think not, given how easy it is to
2878 convert between radixes in gdb.)
2881 This is basically Alessando's code.
2882 It doesn't use obstacks; I changed it to use obstacks
2883 in a few minor places where using malloc causes a
2884 memory leak. (Probably, more places could/should be changed.)
2885 I added record_misc_function where it was missing.
2886 In symbol_file_command and add_file_command, I tried
2887 to make the code consistent with more recent versions.
2888 Minor sylistic changes in parse_procedure.
2889 Make a .gdbinfo. psuedo-symbol point back to the real
2890 procedure symbol (using the isym field).
2893 This is basically from my port, but with a lot of details
2894 and a number of routines merged in from Alessando's version.
2895 I basically used my code "raw" backtrace (use heuristics
2896 from the actual code, rather than symbol table info) - though
2897 the idea is Alessandro's. I feel my code is a little cleaner
2898 here, particularly in being a little more flexible, such as being
2899 able to handle gcc-produced code (which it now can).
2900 It also doesn't do frame caching (which is not useful
2901 more recent gdb versions).
2902 I also used my code for push_/pop_dummy, more or less.
2903 I tried to incorporate AF's code for testing sigtramp
2904 while backtracing; I probably got it wrong.
2905 Added mips_print_register, which tries to scrunch as much
2906 information as possible on a screen...
2907 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2908 under mips-pinsn.c), I don't see anything mips-specific here,
2909 and I don't see it being all that useful anyway.
2912 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2913 Use more register names (rather than hard-cases numbers).
2915 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2917 * Hack up 3.90.11 changes:
2919 * Makefile.dist (depend): parameterize $(GCC).
2920 Add solib.c and solib.o.
2921 (readline): Fix vpath for both absolute or relative SRCDIR.
2923 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
2924 Also, let the part I didn't understand at least compile so
2925 I can test the rest. FIXME.
2927 * dbxread.c: Fix thinko using strcmp.
2928 (init_psymbol_list): declare static.
2929 (partial_symbol_file_open): Comment cleanups better, avoid
2930 cleaning up the string table since the caller will do that.
2931 Move the stat for mod time into symbol_file_command, temporarily.
2932 (There should be a mod time for each symbol file, eventually,
2933 to control its rereading. FIXME.)
2935 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2936 SunOS, which gives error for shared libs otherwise. (From
2937 Schaefer, probably FIXME needs work for portability.)
2939 * solib.c: Move #include "param.h" to work.
2940 Lowercase all the Uppercase Letters In the Messages.
2941 (find_solib): Clean up inferior_so_name for debug printouts.
2942 Allow no argument, to mean all shared libraries.
2944 * symmisc.c: include param.h to get CLEAR_SOLIB.
2946 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

2992 Take code which is shared between symbol_file_command and
2993 add_file_command and put it into partial_symbol_file_{open,read}.
2994 Split add_file_command into add_file_command and add_file.
2995 Make psymtab_to_symtab read in the string table if the file
2997 Two new parameters to read_dbx_symtab and start_psymtab.
2998 tm-sunos.h: New file.
3000 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3017 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3019 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3021 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

3041 copy a makefile into it.
3043 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3044 consistency with POSIX.
3046 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3047 when we exit its exp_valid_block.
3049 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3051 * Makefile.dist: Bump version to 3.91.3.
3053 * Clean up handling of breakpoint commands (somewhat).
3054 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3056 inferior.h: Add breakpoint_proceeded to inferior status struct
3057 and globals; save it and restore it.
3058 (clear_breakpoint_commands): Cleanup, remove old #define.
3060 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3061 (save_inferior_status, restore_inferior_status): handle it also.
3062 (proceed): Remove earlier code that set breakpoint_proceeded.
3063 It is now set only in clear_proceed_status.
3064 (clear_proceed_status): Cleanup, use bpstat_clear rather
3065 than clear_breakpoint_commands. No callers need the stop_bpstat
3066 between clear_proceed_status and proceed.
3068 infcmd.c: Add breakpoint_proceeded definition and comment.
3069 (cont_command, jump_command, signal_command): Move call to
3070 clear_proceed_status right next to call to proceed.
3072 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3073 caller's argument while running down the chain of breakpoints.
3074 Use new variable "breakpoint_proceeded" to determine when
3075 a command that it executes moves the inferior past the
3077 (bpstat_clear): Handle NULL argument.
3078 (bpstat_clear_actions): Avoid useless call to
3079 breakpoint_auto_delete.
3080 (delete_breakpoint): Clean up bpstat's that are pointing to
3081 the deleted breakpoint from the stop_bpstat chain.
3082 (breakpoint_auto_delete): Simplify.
3084 * Clean up handling of EOF, error on stdin, etc. This was
3085 prompted by a network problem that caused gdb to go into an
3086 infinite loop filling up its malloc'd memory.
3088 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3089 not clear_breakpoints_commands, which is now gone.
3090 (main): If command_loop returns (e.g. from EOF on stdin), do
3091 a quit_command (looping back to command_loop if quit_command
3092 doesn't really quit).
3093 (command_loop): check result from command_line_input and
3094 exit if it returns NULL, rather than passing the NULL to
3096 (gdb_readline): Free malloc'd result space before returning
3099 * utils.c (query): Handle C-d to mean "yes", just as if the
3100 input was not a terminal. Also avoid infinite loop if EOF
3101 occurs in mid-input-line before newline. This allows
3102 query to be used at EOF on stdin with reasonable results.
3104 * infrun.c (proceed): Set breakpoint_proceeded.
3106 * values.c (value_as_long): Avoid infinite recursion for enums.
3107 (_initialize_values): Fix typo in help msg (kingdon).
3109 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3110 RL_LIB for linking. This allows -lreadline for linking
3111 and nothing for dependencies, once readline is a real library.
3113 * config.gdb: Jim Kingdon: give useful error message if the
3114 host or target type is not recognized.
3116 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3117 it just defines it. Dumb, but deal with it.
3119 * Jim Kingdon suggests:
3120 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3122 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3124 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3126 * Clean up Bothner's changes.
3128 * blockframe.c (clear_pc_function_cache): New function.
3129 * blockframe.c: remake cache_pc_function_* static.
3130 * dbxread.c (symbol_file_command): remove references to
3131 cache_pc_function_* variables.
3132 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3133 * printcmd.c: Avoid kludging a global variable (addressprint)
3134 to avoid printing the address of a string twice. Instead,
3135 pass the format letter 's' down low enough that it can be seen
3136 to avoid this problem.
3137 (print_formatted): Pass format arg to value_print.
3138 (restore_addressprint): Remove function.
3139 (do_examine): Avoid hacking addressprint, cleanups and such.
3140 (print_frame_args): Add a comment to a Bothner change.
3141 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3142 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3143 to wipe out the values cached in blockframe.c.
3144 * symtab.c (find_method): Add comment saying how big you must
3145 allocate to be "big enough". Per being terse again.
3146 * valprint.c (val_print): Handle format letter "s" to print
3147 strings without addresses. Add comment to vtbl printing code
3148 which casts with wild abandon. Rearrange reference-printing
3150 @0xaddr: value (print w/addressprint)
3151 value (print w/~addressprint)
3152 @0xaddr (parameter lists w/addressprint)
3153 or nothing (parameter lists w/o addressprint)
3155 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3157 * Merge more changes from Per Bothner:
3159 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3160 annoying) that I tried to improve it. Here are my suggestions.
3162 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3165 Do automatic de-reference when taking the address of a reference.
3167 Don't deref_ref when printing parameter lists.
3169 More attempts at treating refernences properly.
3171 In val_print, if deref_ref==0, don't print dangling " = ".
3173 Add COERCE_REF macro, which de-references an REF.
3175 * Merge changes from Per Bothner:
3177 * Fixed (Sony news)-specific configuration problems.
3178 * Fixed other problems with using vanilla pcc and libc (enum problems;
3179 assumption that vsprintf exists).
3180 * Some major speed-ups (finc_pc_partial_function now caches a match;
3181 parsing avoids duplicate symbol_lookup calls).
3182 * Changed handling of baseclasses (no longer use baseclasses field
3183 of struct type, use the first n_baseclasses fields instead).
3184 * Various minor changes/fixes, most C++-related.
3187 Cache the most previous match from find_pc_partial_function.
3188 (Save both low and high ends of matching function's pc range.)
3189 This speeds up the loop of infrun.c:wait_for_inferior quite
3190 a bit, and makes step/next commands much zippier.
3192 Added an enum->int cast (otherwise, some compilers barf).
3194 No longer set baseclass offset to 0, since multiple
3195 inheritance now mostly works.
3196 Added a number of casts, to shut up compiler warnings
3197 (after stabs where made enums, not ints).
3198 When discarding a symbol table (in symbol_file_command),
3199 must clear the cache introduced in blockframe.c.
3200 Don't convert $vtbl_ptr_type to vtbl any more.
3201 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3202 Mask off sign bit emitted by g++ for virtual table offset.
3203 Set voffset to -1 (not 1) for static member functions.
3205 Changed parsing/lexing of names to avoid doing symbol lookup twice
3206 (once when lexing to determine symbol class, once for real).
3207 Now only call symbol_lookup once. Fields of 'this' win especially big.
3209 Subpress printing addr twice in the case of 'x/s addr'.
3211 lookup_basetype_type is no longer used.
3212 Add find_methods as recursive helper function to decode_line_1.
3213 This allows multiple inheritance to work.
3214 Also, once one or more matches has been found, do not look in
3215 base-classes. (Baseclass methods would be overridden, anyway.)
3217 Removed baseclasses array in struct type.
3218 Instead of using baseclasses[i], use fields[i-1].
3219 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3220 Changed sign convention of voffset (previous was inconsistent).
3222 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3224 Used to assume existence of vsprintf. Re-written to not need it
3225 if HAVE_VPRINTF is undefined.
3227 typecmp was too pessimistic. Made it less so.
3229 Don't print space after address.
3230 If vtable points to a misc symbol (with 0 offset), print it,
3231 since that indicates the actual class of the object.
3232 Changed ype_print_derivation_info to use new inheritance
3233 scheme (without baseclasses vector).
3235 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3236 Also, changes needed because TYPE_BASECLASSES were removed.
3238 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3240 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3243 If there is no path set, and the symbols don't indicate what directory
3244 a file was compiled in, look in the current directory. But either
3245 a path or a known compilation directory will prevent this.
3248 Three independent bug fixes:
3249 * Remove the #if 0 block that breaks some stuff.
3250 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3251 adapt gdb to either SunOS 4.0.* or 4.1.
3252 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3255 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3258 (type_print) Demangle the name being printed.
3259 (type_print_base) Handle botched demangling without coredump (tiemann).
3262 (check_stub_method): Document routine.
3263 (tiemann) fix bug for no-arg functions
3264 Avoid clobbering beyond end of malloc'd storage.
3265 Terminate the argument list properly.
3267 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3269 * Changes merged by John Gilmore:
3272 In breakpoint_1, use new print_address_symbolic instead
3273 of find_pc_partial_function. (This forces use of assembler-level
3274 addresses, and avoids misleading non-mangled source-level names.)
3276 Generalize ansi argument such that -1 means skip arglist totally.
3277 Removed global variable print_ansi_qualifiers (which made
3278 code non-reentrant), in favor of extra explicit arguments
3279 to internal routines.
3281 Add new helper function print_address_symbolic.
3282 Use find_pc_misc_function instead of find_pc_partial_function
3283 (since we want assembler-level symbols here).
3285 Print unknown function as just "f (...)", not "f (...) (...)".
3286 Use new fputs_demangled explicitly.
3288 Fixed a typing violation (problem: value.h cannot be imported
3289 without renaming many variable in this file).
3290 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3291 decode_line_1: Moved forward some never-reached code.
3292 Made decode_line_2 skip function prologues correctly.
3294 fputs_filtered should not demangle by default.
3295 Add new fputs_demangled to demangle on demand..
3297 Change value_struct_elt to use value_primitive_field (using recursive
3298 utility function search_struct_field). This allows foo.bar to work
3299 for multiple inheritance (so far only for data fields).
3300 Change check_field in the same way (recursive helper function
3301 to support multiple inheritance).
3302 (Note: there are more of these problems that I haven't fixed.
3303 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3304 value_of_this: 'this' symbol name is now just "this", note "$this".
3306 Don't print static members.
3307 Avoid printing "members of <type>" if there are none.
3308 Simplified type_print_derivation_info by merging duplicate code.
3309 Remove useless blank lines in type_print_base (ptype command).
3311 Added declaration of new routine value_primitive_field.
3313 Added value_primitive_field which is generalized version of
3314 value_field that can handle multiple inheritance (non-zero offsets etc).
3315 Re-implemented value_field to call value_primitive_field.
3317 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3319 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3320 delete the whole environment. Karl Berry reported the bug.
3321 * source.c - fix openp to avoid //'s in filenames, which
3322 trigger an Emacs bug causing it to not be able to find files
3323 when running gdb in a window.
3324 * dbxread.c - zap the #if 0 that botches the add-file code.
3325 It seems to work a lot better without all the code commented out.
3327 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3329 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3332 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3334 * Makefile - added a ${CFLAGS} to a couple of entries,
3335 added remote-sa.sparc.c
3336 * added remote.sa-sparc.c, a modification of remote.c
3337 which conducts a dialog directly with the SparcStation prom.
3338 * breakpoint.c, infrun.c, sparcdep.c added
3339 remote_insert_breakpoint(), and remote_remove_breakpoint()
3340 to breakpoint.c instead of directly writing breakpoint instructions.
3341 * sparcdep.c on remote_debugging,there is no need
3342 to remove signle step breakpoint instructions.
3343 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3345 * printcmd.c - epoch interface sends lisp expressions to open up
3346 epoch windows on inspection.
3347 * valprint.c - added arrayprint, and addressprint and made adding
3348 format controls easier
3349 * wait.h added a couple of undef's because we were getting
3350 complaints about WSTOPSIG and WTERMSIG begin redefined.
3353 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3355 * symtab.c (decode_line_1): Add support for handling method stubs
3356 in the type information.

3360 * values.c (baseclass_addr): Run loop from INDEX+1 to
3361 N_BASECLASSES; otherwise, we can still get into a loop.
3362 @@ This should be restructured to use a cleaner search strategy.
3364 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3366 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3367 abbreviation "Tt" for tags which have the same name as their
3370 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3372 * symtab.c (list_symbols): add ability to set breakpoints on all
3373 the functions which match a particular regular expression.
3375 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3377 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3378 should print ANSI qualifiers (such as `const' and `volatile').
3379 All callers changed to call with ANSI == 1, except from
3380 `check_method_stub', which uses old-style syntax.
3382 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3383 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3385 * values.c (check_stub_method): New function.
3387 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3389 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3390 * valprint (type_print_base): Ditto.
3392 * symtab.c (gdb_mangle_typename): New function.
3394 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3396 * breakpoint.c (catch_command): New function. Provides a
3397 mechanism to set breakpoints based on catch clauses.
3398 (disable_catch): Similar, but disables breakpoints on catch
3400 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3402 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3404 * blockframe.c (blockvector_for_pc): New function.
3405 * blockframe.c (block_for_pc): Changed to call
3406 `blockvector_for_pc' and get the block itself.
3408 * stack.c (catch_info): New function. Prints info about
3409 exceptions which can be caught in the current frame.
3410 * stack.c (print_frame_label_vars): New function. Similar to
3411 `print_frame_local_vars'.
3412 * stack.c (print_block_frame_labels): Prints out labels that are
3413 defined in this frame. These labels are exceptions that can be
3416 * dbxread.c: Updated to handle N_CATCH symtab types.
3418 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3420 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3421 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3422 when printing the type.
3424 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3426 * valprint.c (val_print): Use `baseclass_addr' to access the
3427 baseclasses pointed to via the derived class object at VALADDR.
3429 * values.c (baseclass_addr): New function. Casts derived pointers
3430 to baseclass pointers taking virtual baseclasses and multiple
3431 inheritance into account.
3433 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3437 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3439 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3440 exp_valid_block field correctly.
3442 * infrun.c (wait_for_inferior): When checking "don't even think
3443 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3444 also check step_resume_breakpoint.
3445 Insert breakpoints and continue (not step) if
3446 step_resume_break_address != NULL, even if another_trap.
3447 If trap_expected and we enter sigtramp, then set up a
3449 If trap_expected is set when we hit the step_resume_break,
3451 When calling resume and trap_expected says tell resume to step
3452 (2 places), also check step_resume_break_address.
3454 * infrun.c (wait_for_inferior): Don't set
3455 prev_{pc,sp,func_{start,name}} before calling wait ().
3456 Do set them after exiting loop.

3460 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3462 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3463 Restore old code which distinguishes between trap_expected and
3464 running_in_shell, just make the latter take any non-TRAP signal,
3467 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3469 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3470 xconfig/3b1 (CC,PINSN_CC): Define.

3493 * value.h: Add optimized_out field and change lazy field to
3494 char. Add macro VALUE_OPTIMIZED_OUT.
3496 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3497 instead of stuffing things in buffers (oappend, etc).
3499 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3500 execute_command, exit both loops.
3502 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3504 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3507 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3509 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3511 * valops.c (value_struct_elt), values.c (value_static_field):
3512 Change error messages to remove references to `info methods'.

3517 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
3518 infcmd.c [SHIFT_INST_REGS]: New code.

3526 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3529 findvar.c (get_saved_register): New function.
3530 findvar.c: Rewrite code which called find_saved_register to
3531 call get_saved_register instead.
3533 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3535 * valprint.c (val_print): Change error message printed when
3536 the type has TYPE_FLAG_STUB set.

3569 * coffread.c: Define L_LNNO32 if not defined.
3570 (enter_linenos): Use it.
