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

221 new psymtab for it has been read.
222 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
223 a file, once a new symtab has been read for it.
224 * mipsread.c: FIXME. We need to do the same for MIPS, but it
225 looks harder to determine the top-level block before it's been
226 queued to the psymtab list.
228 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
229 If we have wiped out any old symbol tables, clean up at end of
231 (symbol_file_command): Don't reference symfile_fns if it's zero.
233 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
234 defines for the blocks of a blockvector that contain global and
235 file-static symbols and the first of the smaller scope contours.
236 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
237 decode_line_1, make_symbol_completion_list): Use the above.
238 * coffread.c (end_symtab, patch_opaque_types): Ditto.

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

279 new psymtab for it has been read.
280 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
281 a file, once a new symtab has been read for it.
282 * mipsread.c: FIXME. We need to do the same for MIPS, but it

284 queued to the psymtab list.
286 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
287 If we have wiped out any old symbol tables, clean up at end of
289 (symbol_file_command): Don't reference symfile_fns if it's zero.

292 defines for the blocks of a blockvector that contain global and
293 file-static symbols and the first of the smaller scope contours.

315 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
317 * symmisc.c (free_named_symtab): Make it work, in its current
318 kludgy fashion. Change result to indicate if we blew away bkpts.
319 * dbxread.c (end_symtab): Accumulate result from
320 free_named_symtab and print warning if we blew user's state.
321 * symfile.h: free_named_symtab now returns an int.
323 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
325 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
326 is the first symbol read, even if not mainline.
327 (dbx_psymtab_to_symtab): symfile might be zero, cope.
328 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
329 (set_section_command): New command ("section xxx yyy" -- should
330 be renamed to "set section xxx yyy" FIXME) which sets the
331 base address of a section of the exec file, overriding the
332 virtual address that BFD reports.
334 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
336 * exec.c: Add add_syms_addr_command to exec_ops, so you can
337 load symbols at any address while examining an exec file.
339 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
341 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
342 for printing the float info is host-dependent, not
343 target-dependent. FIXME.
344 * i386-pinsn.c: Move #includes to top, remove useless ones.
345 * i386-tdep.c: Don't bother including <.../reg.h> since we
346 don't use it (and it doesn't exist on host systems).
348 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
349 Convert negative numbers properly.
350 (ieee_test): Make numbers really random; fix format arg.
352 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
353 * core.c (core_detach): Unpush core_ops, which might not be on
354 top. We used to just pop the top, which broke things. Don't
355 need dont_repeat() any more.
356 (core_file_command): Psst! Don't repeat it.
357 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
358 * expprint.c (print_subexp): Avoid switch fallthru on
359 BINOP_ASSIGN_MODIFY, so we can print += and such.
361 * inflow.c (kill_command): After killing inferior, print our
362 current frame in the core file, if we have one.
363 (generic_mourn_inferior): When inferior dies, either select
364 the current frame (in the new target, e.g. core file), or
365 set both the current and selected frames to NULL.
367 Changes from Peter Schauer.
369 * infptrace.c: Avoid <sys/ptrace.h> on USG.
371 * Make all file names fit in 14 characters (sigh and damn!):
372 mv hp300hpux-xdep.c hp300ux-xdep.c
373 mv symmetry-xdep.c symm-xdep.c
374 mv symmetry-tdep.c symm-tdep.c
375 mv convex-opcode.h convx-opcode.h
376 mv tm-vxworks960.h tm-vx960.h
377 mv tm-vxworks68.h tm-vx68.h
378 mv Makefile.srcdir Makefile.sdir
379 mv gdb-int.texinfo gdbint.texinfo
380 mv remote-sa.m68k.shar rem-m68k.shar
381 mv remote-multi.shar rem-multi.shar
382 * Makefile.dist, README, config.gdb, convex-pinsn.c,
383 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
384 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
387 * command.c (user_info_1, user_info): New command for listing
388 the user-defined commands.
390 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
392 * dbxread.c (really_free_pendings): Clear file_symbols
393 and global_symbols after freeing them; otherwise, running
394 this function twice (if it appears twice on the cleanup
395 chain), we try to free things twice.
397 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
398 based on text_addr (the address of text in core), not on addr (the
399 offset between text in the .o file and in core). This change
400 is from Peter Schauer.
402 * main.c: Define ALL_CLEANUPS as a cast of zero.
403 (return_to_top_level): Use it.
404 (main): Do all cleanups after each command run as part
405 of the gdb startup sequence. Also do all cleanups before
406 entering the command loop, and every time we exit the command
407 loop and reenter. Before, the cleanups from the startup sequence
408 were being left undone until the first error!
409 (command_loop): Rename do_nothing cleanup to command_loop_marker
410 so we can see it easily when examining the cleanup chain.
411 (init_signals): Add another do_nothing for signal handling.
412 (quit_command): Only try to kill target if it has execution.
413 Problems in the target stack got us into a state where
414 inferior_pid was nonzero but none of the targets had execution.
415 In this state you couldn't exit gdb.
417 * dbxread.c: Two changes from Peter Schauer.
418 (echo_command): Fflush output after an echo command.
419 (show_history): Pass all args to cmd_show_list.
421 * utils.c (init_malloc): Call mtrace to turn on tracing
422 if the environment variable MALLOC_TRACE is set to a file name.
423 * mtrace.c: Add source file which provides a log of every malloc,
424 free, and realloc to a trace file.
425 * mtrace.awk: Add source file which analyzes the trace file.
426 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
427 (VERSION): Roll to 3.94.3.
429 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
430 (check_duplicates): Don't bother with watchpoints.
431 (set_raw_breakpoint): Comment about danger of this routine.
432 (watch_command): Parse and eval all args before calling
435 * solib.c (find_solib): Avoid error in referencing memory to
436 see if any more shared libraries have been added. This is
437 particularly useful if the target has terminated. Bug reported
441 in bringing up 3.94.2 on the Sun-3.
443 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
444 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
445 expression (in scope) before reenabling watchpoint.
446 * signame.c (init_sigs): Add missing declaration of i, fix
447 sys_siglist declaration.
448 * source.c (list_command): Fixed range computation to use
450 * stack.c (backtrace_command): Do not allow command if target has
451 no stack, print informative error message.
452 * target.c (target_command): Do not write into command line
453 because this fails if the target command is used in a user defined
454 command. [This change was enhanced by gnu to support any-
455 unique-prefix matching on target names.]
456 * valops.c (value_struct_elt): Avoid infinite loop on an
457 erroneous attempt to print the member of function (try p main.p).
459 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
461 * expread.y (name_no_typename): Avoid reduce/reduce errors
462 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
463 Since the GDB parser really doesn't use name_no_typename in a
464 name-only context, the parser can't tell the diff between
465 names and numbers here. Avoid allowing a name_no_typename
466 to be a NAME_OR_*INT to resolve the conflict.
468 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
472 * valprint.c (val_print_fields): bitfield printing didn't handle
473 byte order. Indirect through a few more fns to cope.
475 * values.c (modify_field): also cope with byte order.
477 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
479 Cleanup for release 3.94.2:
481 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
482 include files. Roll version to 3.94.2.
484 * coffread.c (init_stringtab): Read length into unsigned char
485 array before swapping; don't assume 32-bit longs.
487 * target.c (target_info): Don't bother with get_sym_file, just use
488 the symfile global variable.
489 * symtab.h, symfile.c (get_sym_file): Delete it.
491 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
492 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
493 (read_type): Replace one more error() with complain().
495 * mipsread.c (parse_partial_symbols): Replace printf with complain.
497 * i960-tdep.c: Fix copyright attribution.
499 * config.gdb: Quote all backquotes in doublequotes. You can
500 quote me on that. BSD 4.4 shell found this one.
502 * infptrace.c (throughout): The third argument to ptrace is an
505 * infrun.c (wait_for_inferior): When program has terminated, we
506 have to call target_terminal_ours before we pop that target off
507 the stack (e.g. before a call to target_kill or
508 target_mourn_inferior). This fixes problem where a program
509 terminates, then GDB stops for (tty output) and you have to type
510 "fg" to the shell to resume it. FIXME: This code for what to
511 do after termination really should be in normal_stop instead.
513 * gdbcore.h (read_memory_check): Change declaration; it changed
516 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
517 4.4 prereleases, this avoids a bug in their sgtty compatability
519 * remote.c: Use terminal.h rather than hand-rolling the same.
521 * signame.c, signame.h (psignal): Arg is unsigned, not int.
522 * utils.c (strsave, strstr): Fix arg types.
523 * valprint.c (val_print): lint
525 MIPS symbol table support from Per Bothner:
527 * symfile.c (symtab_fns): Remove initializer table that needs to
528 be hacked for each new symbol file format supported.
529 (add_symtab_fns): New function, chains symbol table
530 handlers into the global list.
531 (symfile_init): Search this list.
532 * symfile.h: Add next pointer, declare add_symtab_fns.
533 * coffread.c (_initialize_coffread): Call add_symtab_fns.
534 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
536 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
537 symbol *). Thus, we no longer need the hack to trash
538 pst->filename. Good, since that hack confused code in symfile.c!
540 (reorder_symtabs, destroy_all_symtabs): Removed static
541 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
542 Instead, the latter now uses a temporary array (stack-allocated
543 from an obstack, and then freed).
545 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
546 haven't been set in the outermost stBlock of a procedure. This was
547 a problem with f77 binaries on Ultrix 4.?.
549 (new_symtab, new_symbol, new_type): Continue changing code to use
550 obstacks more and otherwise conform to dbxread internal style.
551 Made the free_code of symtabs be free_linetable (as in dbxread)
552 instead of free_contents. This implies memory leaks when reading
553 a new symbol table, until the conversion is finished. Did change
554 (struct symbol) and (struct type) to be allocated on the
555 symbol_obstack. Blocks and blockvectors are among the things
558 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
559 tested much, but it solved one problem (reported by Meissner), and
560 cleans up some other things. The problem happened when an
561 included file contains actual code (functions) and not just
562 definitions. The mips coff is a little inconvenient there, since
563 it may cause a procedure to be mapped to the wrong psymtab.
565 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
566 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
567 this will need work for the new core paradigm.
569 Opcode patches from the net:
571 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
572 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
573 missing altogether - they are added here. From Bruce Bauman.
574 * mips-opcode.h: The low mask for C0 instructions was too small.
575 From Garrett Lau. I modified the fix to check the entire 32-bit
578 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
581 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
583 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
585 * dbxread.c (read_type): Pointer subtraction (value_sub in
586 valarith.c) sometimes failed because the types of the
587 pointers being subtracted were not identical.
588 These differed because dbxread.c was allocating pointer types
589 using dbx_alloc_type+smash_to_pointer_type instead of
590 lookup_pointer_type. I failed to find a justification for the
591 former, so I changed it to use the latter. Similarly, I
592 replaced smash_to_function_type by lookup_function_type,
593 and smash_to_reference_type by lookup_reference_type.
595 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
596 _initialize_mipsread): corresponding changes.
598 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
600 * source.c (mod_path): Do tilde_expand on each component of the path,
601 rather than on the (list of) paths as a whole.
602 (print_source_lines): Set first_line_listed in addition to
603 current_source_symtab and current_source_line. If the source was
604 not findable, after a "dir" command to fix the problem,
605 a "list" would get the wrong lines.
607 While I was there... (gnu):
609 * dbxread.c (read_type): Change error to complaint.
611 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
613 First attempt at detailed understanding of symbol table memory alloc.
615 * dbxread.c (dbx_symfile_read): Free our string table if we
616 aren't the mainline. Free the "info" struct since we're done with
618 (init_psymbol_list): Free any previously allocated psymbol lists.
619 (): FIXME: Should realloc-down the psymbol lists when done reading
620 the main symbol file?
622 * symmisc.c (free_symtab): Free fullname field too.
624 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
625 (REGISTER_ADDR): Make result type unsigned int.
627 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
628 define REGEX must also define REGEX1 (its dependency).
630 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
632 * tconfig/i960: No longer works, points you at vxworks960 or
635 * xgdb.c, XGDB-README: Remove file. Users can get the much
637 * Makefile.dist: Remove all trace of xgdb.
639 * breakpoint.c (breakpoint_1): Pass demangle arg to
640 print_address_symbolic.
641 (clear_breakpoints): Remove unused function.
642 (breakpoint_re_set_one): Guts of breakpoint_re_set.
643 (breakpoint_re_set): Use catch_errors to do them all anyway.
645 * gdb-int.texinfo (Host versus Target): Add section on what is
646 a "host" feature versus what is a "target" feature.
648 * infcmd.c (path_command, path_info): Handle the PATH variable
649 (object search path) as conveniently as the source search path.
650 * environ.c (set_in_environ): Set some vars in GDB's environment,
651 in addition to the child's. PATH, G960BASE, G960BIN for starters.
652 * source.c (mod_path): New function, from guts of
653 directory_command, modifies a path. Used by path_command.
654 (directory_command): Call it.
655 * defs.h (strsave): Declare.
657 * utils.c (sevenbit_strings): Add new printing option.
659 (strsave): Provide this handy helper routine.
660 (set_width_command): Rename set_screen_width_command.
661 (_initialize_utils): "set screen-width" => "set width";
662 "set screen-height" => "set height"; add sevenbit-strings.
664 * infcmd.c (do_registers_info): Print floating point registers
665 in raw hex as well as float format, regardless of whether it is
666 a "virtual" convertible register.
667 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
668 regs as a double, just in case it's being used that way.
669 * values.c (unpack_long): Comment on array/function coercion.
670 (unpack_double): Argument is in target byte order now. For
671 integer arguments, just call unpack_long and float the result.
672 * m68k-tdep.c: include defs.h for "const" handling.
673 * remote-nindy.c: Use ieee-float stuff.
674 (nindy_fetch_registers): Unpack double regs to host double, then
676 (nindy_store_registers): Pack extendeds to host double, flip
677 around by misusing unpack_double, send as target double.
679 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
680 zero, as when stopped at the first instruction of a process.
682 * blockframe.c: Fix filename in comment (param.h => tm.h).
683 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
684 * tm-68k.h: Fix typos.
686 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
688 Changes from a bringup on the DEC Vax under Ultrix 4.0.
690 * coredep.c (fetch_core_registers): Pass end-address of register
691 section to register_addr as expected. Don't call supply_register
692 if we'd just pass it garbage.
694 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
696 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
698 * target.c (push_target, target_info): Cast enums to int for < or
701 * stack.c (print_frame_info): Identify source file & line
702 even if we can't print it.
704 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
706 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
708 Clean up IEEE floating point support.
710 * ieee-float.h: New file.

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

794 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
795 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
796 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
797 declarations of errno.
799 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
801 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
802 <rpc/rpc.h> and <rpc/types.h>.
804 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
806 * i960-tdep.c (examine_prologue): Add new argument limit,
807 which stops the scan at the end of the prologue, or at the PC.
808 This fixes a problem where it walks down into the code for the
809 user's statements if that code looks like function prologues.
810 Mark Fox and I have been bouncing this code back and forth, making
811 small changes to it. Callers changed to match.
813 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
815 Cleanup for gdb-3.94 release final:
817 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
818 the .c files from vx-share and nindy-share, from the various
819 macros, since they are not found via ALLDEPFILES.
820 (SFILES): Add tm-i960.h.
821 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
822 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
824 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
825 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
827 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
829 * am29k-tdep.c: Add contribution line.
830 (examine_prologue): Cache information about function prologues in
831 the misc-function-vector to avoid lots of references over the
832 serial line while examining instructions.
834 * core.c (core_close): New function made from cleanup_core.
836 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
837 remote-vx.c, remote.c, target.c, target.h,
838 Update target_ops vector to add attach, close, and load entries.
839 Use add_syms_addr_command, not add_file_addr_command, for
840 add_file. Break out close routine from existing code.
842 * dbxread.c (really_free_pendings): Don't free pending_blocks;
843 they are in an obstack.
844 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
846 (define_symbol): Add symbol type parameter; change callers;
847 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
848 it to influence the symbol class on the i960.
849 (define_symbol): Swap LOC_CONST's into target byte order.
851 * exec.c (exec_close): New function.
852 (exec_file_command): Call it.
854 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
855 Fix byte order of frame pointer.
856 (read_var_value): Result of 0 if var's value can't be found,
857 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
858 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
859 (locate_var_value): Use read_var_value and use its lazy address
860 as the location of the var's value. Lint.
862 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
865 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
866 obsolete Intel versions in favor of vxgdb versions.
867 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
868 code dealing with byte order of values, which Intel did in host byte
869 order rather than gdb-4's target byte order.
870 (i960_frame_chain_valid): Move to nindy-tdep.c.
871 (examine_prologue, skip_prologue, frame_find_saved_regs,
872 frame_args_address, leafproc_return, saved_pc_after_call,
873 pop_frame): Add vxgdb versions from Mark Fox.
874 (examine_prologue, frame_struct_result_address): Add code
875 to deal with the saved value of G13 (struct return address
877 (frame_args_address): Modify Mark's version to prefer the
878 saved value over the current value in the topmost frame.
879 Cache result in the frame info to avoid performance hair in
881 (print_fault): Add gdb960 code for printing faults.
882 (_initialize_i960): Actually call check_host.
884 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
885 add stub routines. FIXME, these currently just return zero!
887 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
888 (attach_command): Call target_attach, not target_open, now.
890 * infrun.c (normal_stop): Make global, not static, for vx_attach.
891 (child_attach): Rename from child_open.
892 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
893 don't confuse it with a zero step_resume_break_address.
895 * inftarg.c (child_detach): Eliminate inferior_pid test.
896 (child_files_info): Clean up message a bit.
897 (child_ops): Use child_attach, not child_open, to attach.
899 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
900 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
901 findvar.c to here, since it depends on the contents of the
902 shadow_contents of breakpoints, but keep if #if 0 since it is
905 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
908 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
909 (ptype_command, display_command): Eliminate have_inferior_p and
910 have_core_file_p in favor of target_has_stack or
911 target_has_execution.
912 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
913 code for actually finding the values of arguments, though we still
914 keep track of the maximum stack offset for use in printing unnamed
915 arguments. Handle missing FRAME_ARGS_ADDRESS.
917 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
918 (struct nindy_regs): Define registers passed to/from nindy.
919 (nindy_fetch_registers, nindy_store-registers): Translate between
920 nindy and GDB formats for the registers.
921 (dcache_init): Statically allocate the cache, since it was being
922 allocated by a malloc that was never freed anyway.
923 (nindy_create_inferior): Error, not core dump, if no exec file.
924 (nindy_before_main_loop): Use target_load, not target_add_file.
926 * remote-vx.c (net_load): Specify large timeout for load
927 requests. Allow user to break out with INTERRUPT.
928 (net_break): Remove useless code, clean up. Change callers.
929 (parse-args, skip_white_space, find_white_space): Clean up arg
930 parsing to cope with quoted strings.
931 (net_wait, net_quit): Never call error, just return status.
932 (vx_read_register, vx_write_register): Cleanup status checking.
933 #ifdef the code based on which CPU we are using (960 or 68k),
934 FIXME, this should be completely general but it isn't yet.
935 (vx_xfer_memory, vx_resume): Cleanup status checking.
936 (vx_run_files_info): Improve message.
937 (vx_load_command): Renamed from vx_add_file_command. Allow load
939 (net_ptrace): Remove unused routine.
940 (vx_wait): Adopt code from vxgdb960 to cope with broken
941 connections to target machine and prompt to disconnect. Remove
942 debug printouts. Map some EVENT_'s to SIGnals.
943 (add_symbol_stub, vx_open): Print names of object files we found,
944 and "ok" if we read their symbols OK. Clarify output in general.
945 (vx_attach, vx_detach, vx_kill): Add these commands.
946 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
947 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
948 "info files" output, and create_inferior, since we already have
951 * stack.c (frame_info): Replace Frame_unknown with 0.
952 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
953 (return_command): Pop until the PC matches as well as the FP,
954 so it works even if the FP is shared with another function,
955 as in "frameless" or "leaf" procedures.
957 * symfile.c (load_command): renamed from add_file_target_command.
958 (add_syms_addr_command): renamed from add_file_addr_command.
959 (add_syms_command): Stub to call target_add_syms.
960 (_initialize_symfile): Change command names and descriptions,
961 add-file => add-syms, and load from alias to its own command.
963 * target.c (kill_or_be_killed, maybe_kill_then_attach,
964 maybe_kill_then_create_inferior): Default for attempts to start
965 a process, if one is already running, is to ask about killing
967 (upstack_create_inferior): #if-0 it, strata obsolete it.
968 (push_target, unpush_target, pop_target): to_close() a target
969 before unstacking it.
970 (target_info): Renamed from target_files_info.
971 (_initialize_targets): Rename "i files" as "i target", accessible
974 * target.h: Improve comments about the target_ vectored routines.
976 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
977 Convert commenting style to standard GNU style.
978 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
979 (SKIP_PROLOGUE): No longer a no-op.
980 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
981 (*_REGNUM): Sort register numbers.
982 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
983 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
984 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
985 are now 10 byte extendeds, not 8 byte doubles.
986 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
987 for nindy versus vxworks targets. FIXME, this should possibly go
988 in the target vector.
989 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
990 frame_saved_regs and arg pointer with each frame.
991 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
992 (FRAME_ARGS_ADDRESS): Use cached result.
993 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
994 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
995 (PRINT_RAMDON_SIGNAL): Call print_fault.
996 (POP_FRAME): Now works.
998 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
999 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1000 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1001 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1004 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1005 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1007 * valarith.c (value_subscripted_rvalue): Avoid handling
1008 floats and doubles specially; it gave alignment errors. Lint.
1010 * valops.c (value_of_variable, value_of_this): Error if unknown
1013 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1014 to avoid alignment problems.
1015 (value_print): Handle unknown value address.
1016 (cplus_val_print): Two args are ignored; remove them. Change caller.
1017 (val_print): Use unpack_long rather than pointer-deref.
1020 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1021 to avoid alignment problems.
1022 (value_being_returned): Error if return value unknown.
1023 (set_return_value): Add bogosity warning, FIXME. *
1025 * TODO: A woman's work is never done.
1027 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1028 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1029 Add ieee-float.o to OBS.
1030 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1031 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1032 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1034 Changes to generalize the VxWorks RPC protocol slightly, to handle
1035 i960 as well as 68000.
1037 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1038 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1039 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1040 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1041 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1042 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1043 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1044 so they will move in target byte order rather than network
1045 byte order (happens to be the same).
1047 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1049 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1051 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 Add contribution lines to various files, showing where they
1057 * breakpoint.c (break_insn, check_break_insn_size,
1058 read_memory_nobpt): Remove to mem-break.c.
1060 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1063 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1064 entry has bad register number. This change is not
1065 tested in this release, FIXME.
1067 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1070 * value.h: Force value's contents field to be aligned to hold
1071 at least a double or a long long (if supported). This avoids
1072 doing bcopy's in and out of the contents field.
1074 (step_1): Avoid coredump under obscure circumstances when we
1077 * symtab.h (misc_info): Add field to misc function vector for
1078 any kind of cached information the target code desires. AMD
1079 29000 uses this to avoid repeating examine_function_prologue's.
1081 * coffread.c: Lint. Remove static symfile, read_section_header.
1082 core.c (have_core_file_p): Lint: remove.
1083 expprint.c (print_subexp): Lint.
1084 infptrace.c, valops.c, valprint.c: lint.
1086 Roll in changes from vxgdb-5.0.1:
1088 * symtab.h: Comment byte order of each address class. Add
1089 LOC_LOCAL_ARG for frame-relative args (960).
1090 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1091 symtab.c, symmisc.c: ditto.
1093 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1095 * remote.c (remote_resume): Error if resume with a signal.
1097 * symfile.c (prim_record_misc_function): Clear misc_info.
1098 (fill_in_vptr_fieldno): Check stub type of arg.
1100 * valops.c (value_cast): Avoid looking up names of types whose
1101 name we don't know, to prevent coredump. Sun CC produces typedef
1102 rtx and the name of *rtx is zero...
1104 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1106 Roll in changes from final AMD 29000 port (Tiemann).
1108 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1109 for ../include/a.out.encap.h. This might not work now that BFD
1110 is separately compiled. Instead, BFD support for encap will have
1111 to translate machine type 29k into the right COFF_MAGIC.
1113 * infcmd.c: Remove references to inferior_pid that aren't used
1114 in actual ptrace calls; use target_has_execution, etc.
1115 (have_inferior_p): Remove function.
1116 (program_info): Print target info rather than "process number";
1117 avoid gratuitous messages unless from_tty.
1118 (run_stack_dummy, finish_command): Set proceed_to_finish.
1119 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1120 main.c: Lint. Lose have_inferior_p().
1121 inferior.h (have_inferior_p): Remove, lint.
1122 (proceed_to_finish): Add flag to ask that all regs be saved
1123 by normal_stop, for the few commands that need it, speeding up
1124 serial I/O. Add comments to stop_registers.
1126 * remote-eb.c: Remove newline from breakpoint message we grep
1127 for. Never time out when running the user program.
1131 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1133 Roll in changes from vxgdb-5.0.1:
1135 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1136 symbol in its raw form, we are processing an unlinked ".o" file.
1137 See if the target environment has assigned it an address, using
1138 target_lookup_symbol (VxWorks does), and enter it into the symtab
1141 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1142 68k versions for a simpler version that assumes zero FP at bottom.
1143 Fixes bug of truncated stack reports.
1145 * target.h (target_lookup_symbol): Define this routine's args
1146 and result, finally.
1148 * target.c (nosymbol): Default routine for target_lookup_symbol.
1149 (target_default): Default lookup_symbol and call_function too.
1150 (files_info): Only print has_all_memory warning if a non-dummy
1153 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1154 vx_convert_from_virtual): If target does not have floating point,
1155 zero register "values", and avoid doing cross-net conversions.
1156 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1157 (vx_open): Rearrange code that attaches to target and reads
1158 symbols for all loaded modules, to work if some of the modules
1159 are not accessible. Add symbol_stub() and add_symbol_stub()
1160 as callbacks from catch_errors(). Allow connect attempt to be
1161 interrupted painlessly with ^C (FIXME, there are still some bugs
1162 if the interrupt happens during symbol reading.). Print
1163 final message with puts_filtered, since symbol messages are
1168 * main.c (catch_errors): Only print errstring if non-null.
1169 (command_loop): Avoid an ioctl per command to test ISATTY.
1171 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1172 (vx_xfer_memory): Return correct result!
1173 (vx_files_info): Indicate whether target has float or not.
1174 (vx_lookup_symbol): Complain, not error, if target gone.
1175 (vx_open): Print "Connected" msg before disabling immediate-quit.
1176 [FIXME: lookup_symbol and vx_open changes need testing.]
1178 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1179 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1180 contributor lines and update copyrights to 1991.
1182 Changes from an attempted H-PUX host port:
1184 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1185 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1186 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1187 * remote-vx.c: include <sys/time.h> for HPUX.
1188 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1189 "core_file_command" routine to BFD regime. May not work yet.
1191 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1193 * xgdb.c: Replace X10 version with some VJ version.
1194 (FIXME: Its copyright assignment is not on record.)
1195 * xgdb.c: Update include files to X11R4 (Xaw crud).
1196 (xgdb_display_source, create_text_widget): fix call to
1197 get_filename_and_charpos. Rewack source window stuff for X11R4
1198 (gleaned from include files, and "nm's" of binary libraries, since
1199 I had no doc available).
1200 (append_selection, append_selection_word): Disable with FIXME
1201 since R4 changed interface here.
1202 (create_buttons): Add back the old set of buttons.
1203 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1205 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1206 Roll VERSION to 3.94 (not yet final though).
1208 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1210 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1211 obstack_int_grow, obstack_int_grow_fast): Eliminate
1212 cast on left of assignment, which gives MIPS cc fits and is
1215 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1216 F_ALIAS. Use printf, not fprintf, when not passing a file
1218 (compare_opcodes): Check that identical instructions have
1219 identical opcodes, complain otherwise.
1221 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1222 was reported by Roland McGrath.
1223 (unimp): Only match if exactly zero instruction. (Roland)
1224 (branches and traps): Generate all variations of these
1225 instructions with macros, based on a single call that defines
1226 each condition name and its binary representation.
1227 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1229 * valprint.c (val_print_fields): Take, and use, format parameter.
1230 This means that "p/x struct" again prints the elements in the
1231 desired format. Changed callers.
1233 * stack.c (frame_info): Use filtered output, and indicate wrap
1234 points. Remove kludgy formatting designed to avoid line wrap.
1236 * utils.c (wrap_here): If the line is already full (because
1237 we had printed a long indent or long wrapped string), do an
1238 immediate newline-and-indent.
1240 * m68k-pinsn.c (print_insn_arg): Bugfix from
1242 instruction is incorrectly disassembled as bkpt #8.
1244 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1246 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1247 and then will dump core (sometimes). I traced it back to an
1248 uninitialized symfile_name in psymtab_to_symtab.
1249 (const_vol_complaint): Add quotes to message.
1250 (define_symbol): Only believe line number if gcc_compiled.
1251 Avoid allocating symbol if we will not return it.
1253 Add target strata support so that newly established targets go
1254 into their right place in the target stack (e.g. a new exec file
1255 doesn't wipe out the ability to access the running process).
1257 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1258 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1259 and initialize it properly in all the targets.
1261 * target.h: Document strata. Change return type of push_target.
1263 * target.c (nomemory): new function for dummy memory access.
1264 (tcomplain): Rename complain, now also used in symfile.c.
1265 (push_target): Push targets within strata. New return value shows
1266 whether new target is on top of stack or not. Always keep dummy
1268 (target_files_info): Ignore dummy target.
1270 * core.c (core_open): Warn user, and skip accessing file, if the
1271 core target is not the topmost target in the stack.
1272 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1275 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1276 target_ops, it doesn't belong there since we have no regs there.
1277 Change name of target from machine => memory to clarify.
1279 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1281 * Freeze version 3.93 for release.
1283 * Makefile.dist: Handle vx-share and nindy-share subdirs
1284 properly when building gdb.tar.Z.
1286 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1287 printed in various places, so I could change just one copy.
1289 * dbxread.c, coffread.c: Change references to bfd->iostream
1290 to cast to FILE *, now that BFD avoids needing types defined
1291 in other header files.
1293 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1295 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1296 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1297 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1298 (actually gcc -Wall).
1300 * dbxread.c: Remove first_global_sym, last_global_sym, since
1301 they are never referenced.
1303 * defs.h (baud_rate): Declare.
1304 main.c: Define it, and add the -b option to set it.
1306 * gdb-int.texinfo: Add text on how to define a new host or target
1307 architecture, prompted by Per Bothner's questions about MIPS
1310 * gdb.texinfo: Document "complaints". Change doc of -q since
1311 gdb no longer prints the copyright and blurb if you specify a file
1312 name to be debugged (just like Emacs). Add doc for Nindy-specific
1313 command line flags for specifying target serial port and such.
1314 Update copyright to 1991.
1316 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1317 has taken over for us the job of ripping up executable files. The
1318 crud caused Per Bothner's port to not compile.
1320 * infrun.c (normal_stop): Avoid printing "Program exited
1321 normally" if we are in batch mode. This allows a GDB which
1322 executes a program on a target system, to behave like a Unix
1323 command (input from stdin, output to stdout, no extraneous
1326 * main.c (main): Allow additional machine-dependent command line
1327 options to be specified with the ADDITIONAL_OPTIONS,
1328 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1329 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1330 processing to occur just before the main loop with
1331 BEFORE_MAIN_LOOP_HOOK.
1332 (main): If a "core file" argument is specified, and it is not a
1333 core file, try it as a process ID to attach.
1334 (symbol_completion_function): Attempt to cope with
1335 "show screen-" TAB, not very successfully. This needs more work,
1337 (batch_file): New function, returns whether we are reading
1338 commands from an interactive tty on stdin, or from somewhere else.
1339 Called by normal_stop since it doesn't get from_tty passed down
1340 to it like many commands do.
1342 * remote-nindy.c: Handle command line options for nindy
1344 (nindy_before_main_loop): Prompt user for tty name if they
1345 don't specify it before getting to the interactive command loop.
1347 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1348 and -r command line options. Also add hook before main loop
1349 to make it easy to specify a tty.
1351 * TODO: More things to do, one done.
1353 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1355 * dbxread.c: Make complaint() calls pass pointer, not struct.
1356 Add complaints about badly formatted C++ type information
1357 (const/volatile indicator, and parse errors resulting in
1358 error_type). Fix C++ virtual member fn comment.
1359 (read_struct_type): Avoid bumping pointer if we got a parse
1360 error; this prevents our walking beyond the end of a string.
1361 Terminate loop on null char as well as semicolon.
1362 (process_one_symbol): Fix the LBRAC fix so that it uses the
1363 last previous SLINE, FUN, or SO record's PC address. C++ debug
1364 symbols did not have SLINE records in a useful order compared
1365 to the LBRAC records.
1366 (define_symbol): Handle "catch" records.
1368 * symtab.c (check_stub_type): Added new complain
1369 `stub_noname_complain' and added a consistency check to
1370 keep the debugger from crashing when finishing from an
1371 exception frame. A real fix will be needed later.
1373 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1375 * infcmd.c (attach_command): Make global.
1377 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1378 but make them easy to comment out. Perhaps later they should
1379 be enabled by what CPU you configure for? FIXME.
1380 (VERSION): Roll to 3.93.
1381 (pinsn.o): Remove rule for obsolete file.
1382 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1384 Run down a problem that manifested by printing the wrong function
1385 name in stack traces of read_ofile_symtab. Turned out that the
1386 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1387 the LBRAC symbol with an address in the *data* segment, which
1388 blew our binary search through the blocks.
1390 * dbxread.c: Use the complain() facility consistently to bitch
1391 about problems in the symbol file we are reading.
1392 (finish_block): Add code to check the nesting of the blocks;
1393 complain and Procrust them to fit if wrong.
1394 (make_blockvector): Check the order of the blocks, complain
1395 [but don't cope] if wrong.
1396 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1397 symbols to be sure their PC value is greater than the last SLINE
1398 (line number) symbol we've seen, complaining and adopting the
1399 SLINE PC value if wrong.
1401 * symfile.h (struct complaint, complaint_root, complain,
1402 clear_complaints): Add.
1403 * symfile.c (complain, complaint_root, clear_complaints): Add
1404 facility to deal with non-fatal complaints and to regularize their
1406 (symbol_file_add): Clear complaint counters to allow new complaints.
1407 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1409 * dbxread.c (dbx_symfile_read): Remember the address and size
1410 of the string table for the main symbol file, so we won't read it
1412 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1413 to avoid reading the string table yet again. Lint.
1414 (throughout): Improve filtered output, including word wrap.
1415 (read_range_type): Improve Bothner's fix to handle other types too.
1417 * utils.c: Improve line wrap implementation. Handle unlimited
1418 width by making chars_per_line unsigned.
1419 (puts_filtered): New, easy, function.
1421 * defs.h (puts_filtered): add.
1423 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1424 call the identical sort_symtab_syms() in symfile.c instead.
1426 * expread.y: Suggest the `file' command rather than `symbol-file'.
1428 * command.h (enum var_types): Add zinteger for seroable
1430 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1431 nested if's into a switch.
1433 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1434 we did not stop because of a breakpoint (it must have been for
1435 some other reason, like a "stepi"), so don't print anything.
1437 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1438 doesn't include <sys/types.h>, old SunOS's require it for
1443 A test port of gdb-3.92.6 to the Sony NEWS.
1446 Don't normally link in remote- or vx stuff.
1447 Some of it doesn't compile, and it wastes space for 99% of the users.
1448 Remove reference to no-longer-used HAVE_VPRINTF.
1449 Fixed BFD_DEP typo to BFD_DIR.
1451 Fix cast in arg to bfd_h_getlong.
1452 Make char *prefix be const.
1453 Fix how certain range types are mapped into builtin unsigned int types.
1455 Remove 2 #includes. They cause errors (on Sony, at least),
1456 and aren't needed (they wern't in earlier versions).
1458 print_address_symbolic should never demangle labels
1459 (since it prints *assembler-level* labels).
1461 [This was superseded by the change to printcmd below.]
1464 Add some "volatile" return types to avoid warnings.
1465 If MISSING_VPRINTF add vprintf function and not just macro
1466 (since vprintf is used in printcmd.c).
1468 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1469 (The latter isn't grokked by some PCC-based compilers.)
1471 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1473 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1474 * nindy-share/coffstrip.c
1475 Added some forward declarations (otherwise, gcc complains
1476 about implicit extern redefined as static).
1478 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 Changes inspired by Per Bothner:
1481 * printcmd.c (print_address_symbolic): Take additional parameter
1482 specifying whether to demangle.
1483 (print_address): Pass in asm_demangle to control demangling.
1484 (print_address_demangle): New fn, takes explicit arg to control
1486 * utils.c: Add new vars demangle and asm_demangle, and let them
1488 (fputs_demangled): If !demangle, just print the argument.
1489 (fprint_symbol): If !demangle, just print raw symbol.
1490 * valprint.c (val_print): Call print_address_demangle rather than
1491 print_address, to cause demangling to depend on the global
1492 rather than assembler-level demangling setting.
1493 * WHATS.NEW, gdb.texinfo: Document.
1495 * main.c (show_command): Show all settings if no arg.
1496 (initialize_main): Make "info set" the same as naked "show".
1497 * command.c (cmd_show_list): Handle prefix commands in the
1498 list, and print the name of the setting as well as its English
1499 description and value.
1501 Allow gdb functions to specify where a line should wrap if it
1502 exceeds the size of a terminal line. Use it to make the output
1504 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1505 of the right size when screen width changes.
1506 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1507 (wrap_here): New fn, indicates a point in the output where we
1508 should wrap the line rather than just letting it overflow at a
1510 (fputs_filtered): Implement wrapping.
1511 (n_spaces): New fn, returns a pointer to N spaces.
1512 (print_spaces_filtered): Use n_spaces.
1513 * defs.h (n_spaces): Declare.
1514 * stack.c (print_frame_info): Wrap with 4-space indent after
1515 fn name and before filename and line number.
1516 * printcmd.c (print_frame_args): Wrap with 4-space indent
1517 before each argument name is printed.
1518 * valprint.c (value_print): Wrap with no indentation before
1520 (val_print_fields): Wrap with indentation relative to nesting
1521 level before each field name.
1522 (val_print): Wrap with nesting indentation before array elements.
1523 * command.c (do_setshow_command): Avoid extra newlines,
1524 wrap with 4-space indent around values printed, end with period.
1525 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1527 * breakpoint.c (breakpoint_1): Implement addressprint for
1528 "info breakpoints" display. Change file name and line number
1529 format to " at file:nnn" rather than " (file line nnn)".
1530 * gdb.texinfo: Document.
1533 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1535 Frozen for gdb-3.92.6 release.
1537 README, WHATS.NEW: Update for 3.92.6 release.
1539 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1540 coffread.o from configs since it is now built by default.
1541 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1542 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1543 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1544 from configs since it is now built by default.
1546 Makefile.dist: Update for release 3.92.6. Handle files that
1547 have been moved to ../include, ../getopt, or ../bfd. Add
1548 saber.suppress and tests directory. Add config.status to
1549 the release (it will say "none").
1551 coredep.c: Minor formatting fixes.
1553 These changes were made in early December but only checked in now:
1554 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1555 nindy-share/nindy.c: lint
1556 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1557 register values coming back from the target; we store values
1558 in target byte order everywhere.
1560 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1562 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1564 * valprint.c (cplus_val_print, val_print_fields): New functions,
1565 which print C++ objects. They conspire to avoid printing a
1566 virtual base class more than once, following all the twists and
1567 turns of C++ virtual base rules.
1568 (val_print): Call the above rather than do it by hand.
1570 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1571 symbol file, not for added files like shared libs. This really
1572 needs to be generalized to a timestamp per file.
1574 * core.c (cleanup_core): Avoid coredump if no core file.
1576 * config.gdb: Accept -host or -target in place of +host or
1579 * coffread.c (find_linenos): Avoid desupported BFD interface
1580 to line numbers. We still read them manually rather than using
1581 BFD's "generic" features.
1583 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1585 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1587 * Makefile.dist: Eliminate use of $< in explicit targets.
1589 * readline/Makefile: Use $< rather than $*.c, which does not
1590 include the VPATH in GNU Make.
1592 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1593 copies of tconfig/i960, added for global configuration
1594 compatability. All i960 versions can read both coff and b.out.
1596 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1597 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1600 * TODO: Think of more things to do.
1602 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1604 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1605 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1606 64-bit float conversion.
1608 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1609 equivalent to sun?os4 so global config works.
1611 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1615 * main.c: Only declare linesize once; declare pagesize not at
1616 all, since it is never used.
1617 (main): Clear newly allocated line before it is used.
1619 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1621 Further stabilization for the Intel 960.
1623 * Makefile.dist: Parameterize the location of the "include"
1624 and "bfd" directories, as well as "getopt". Add symfile.c.
1625 Link in both dbxread and coffread. Fix up "make depend" to
1626 rewack the locations of include, bfd, and getopt in its output.
1628 * README: Document moving include files, improve some of
1631 * coffread.c: Move common code out to symfile.c. Change
1632 symbol_file_command style interface to use new *_symfile_init
1633 and *_symfile_read interface under BFD. Use BFD internal
1634 info to locate line table, symbols, etc.
1636 * core.c (core_fetch_registers): Rename to get_core_registers
1637 to avoid confusion with fetch_core_registers.
1638 (register_addr): Move to coredep.c, which is already machine
1639 dependent. This leaves core.c pretty clean of dependencies.
1641 * coredep.c (register_addr): Accept this routine from core.c.
1643 * dbxread.c: Move common code (with coffread.c, etc) into new
1644 symfile.c. Each psymtab now contains a pointer to the
1645 format-dependent function that knows how to read it in. Make
1647 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1648 (process_one_symbol): Add code to complain about a "compiler bug
1649 we muzzle here", if we actually see it.
1651 * eval.c (evaluate_subexp): Insert missing "break" statements
1652 in code that determines whether a variable is an lvalue in
1653 memory, register, or whatever. I detected this via a compiler
1654 bug in which it *almost* mashed out the whole switch statement.
1656 * gdb-int.texinfo: Add minor sections on configuring gdb for
1657 release, and about the README file.
1659 * infcmd.c (registers_info): Fix formatting somewhat. Still
1660 not as pretty as before, but it handles byte swapping.
1662 * remote-nindy.c: If data cache routines are interrupted while
1663 waiting for the remote end, be sure that any uninitialized cache
1664 blocks are on the free list, not on the valid list!
1666 * symfile.h: Flesh out this header file with all the various
1667 routines and variables that have been merged in from dbxread.c
1668 coffread.c, and symtab.c to symfile.c.
1670 * symfile.c: New file, containing code common to dbxread.c,
1671 coffread.c, and some code from symtab.c. All generic code for
1672 reading symbol files should be in here now.
1673 (unrecord_misc_function): Remove unused function.
1675 * symtab.h: Remove file-reading things to symfile.h.
1677 * symtab.c: Remove file-reading things to symfile.c.
1679 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1680 to decode i960 fault types.
1682 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1683 target.c: Change type of the "resume" function from int to void,
1684 since its result was never used.
1686 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1688 * main.c: Replace "stupid" with "caution"; you now "set caution
1691 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1693 * infcmd.c (do_registers_info): Call val_print to deal with the
1694 byte order of the registers being printed. FIXME, this makes
1695 the formatting of the output uglier.
1697 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1698 defined, call it for signals the debugger doesn't itself use.
1699 The i960 uses this for more detailed fault information.
1701 * remote.c (remote_open): If arg is null, print help rather than
1704 * sparc-xdep.c (register_valid): Avoid declaring size, since
1705 various modules will think of various sizes depending on the
1706 architecture of their tm-file. FIXME, we need protection against
1707 actually entering one of those modules, which would clobber
1708 storage if not for the target architecture compiled into gdb.
1710 * stack.c (up_command, down_command): Always print the frame
1712 (up_silently_command, down_silently_command): New commands
1715 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1717 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1718 more parameters than it used to.
1720 * findvar.c (registers): Increase slop to 256 bytes, which should
1721 protect us against even most RISC machines with large register
1723 (locate_var_value): Move declaration inside related ifdef.
1725 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1726 throughout, to avoid throwing away buffered input from the board.
1727 (nindy_wait): Supply_register takes addr_of_value, not value.
1728 (i960_print_fault): Renamed from i80960_fault.
1729 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1730 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1732 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1733 we can set the PC in the call to proceed(). Unpush nindy_ops
1734 before pushing it on top, to avoid message to user. Eliminate
1735 commentary from Unix machines that just misleads here.
1736 (reset_command): Fix error message to suggest target command.
1738 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1740 Release 3.92.5 as frozen.
1742 Stabilize the merged release...with help from lint, Saber C,
1745 Everywhere: Add include files needed to declare return types
1746 of functions called.
1748 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1750 * breakpoint.h: Add undeclared breakpoint functions, and some
1751 functions for display handling since I couldn't think of a better
1754 * breakpoint.c (insert_breakpoints): Make code for disabling
1755 shared library bkpts more likely to work. It's used when we
1756 rerun a program and stop before the shared library has been
1758 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1759 cast from pointer, so it squeezes through catch_errors.
1760 (bpstat_stop_status): Fix logic broken some time ago. We now
1761 always create a bpstat if the stop address matches a breakpoint,
1762 even if we don't stop there -- just like the old code used to do
1763 before I got my fingers into it (sigh).
1764 (breakpoint_1): Print "ignore count" after "stop only if"
1765 condition, since that's how it actually works.
1766 (mention): Handle watchpoints as well as breakpoints.
1767 (watch_command): use set_raw_breakpoint and mention to do most
1768 of the work (and initialize all the fields!). Only pass one
1769 arg to parse_c_expression, since that's all it takes.
1771 * command.c (not_just_help_class_command): Rename arg to args
1772 since we ignore "unused argument" warnings on vars named "args".
1773 inflow.c (child_terminal_info): ditto.
1774 infptrace.c (kill_inferior): ditto
1775 main.c (catch_errors, version_info, quit_command, pwd_command,
1776 source_command, dump_me_command, editing_info,
1777 set_history_size_command, set_history, show_history,
1779 stack.c (locals_info): ditto
1780 target.c (target_files_info): ditto
1781 valprint.c (set_input_radix, set_output_radix): ditto
1783 * core.c: Remove old variables for handling core and exec file
1784 sections (data_start, data_end, stack_start, stack_end,
1785 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1786 text_end, exec_data_start, exec_data_end, text_offset,
1787 exec_data_offset, data_offset, stack_offset). They're
1788 superseded the more general build_section_table and
1790 (get_exec_file): Mention the `file' command.
1791 (read_memory_check): Rename to memory_error, and only call it
1792 in the case of an actual error.
1793 (read_memory, write_memory): call memory_error.
1794 (core_fetch_registers): Register section name is ".reg".
1796 coredep.c: Remove a bunch of crud now that all this file does
1797 is pull the registers out of a core file.
1798 (fetch_core_registers): Rewrite to actually work, I hope.
1800 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1801 Replace index() with strchr(). Remove all the pre-BFD macro
1802 definitions for accessing the symbol file.
1803 (struct dbx_symfile_info): Encapsulate the information that
1804 dbx_symfile_init needs to pass to dbx_symfile_read in this
1807 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1808 dbx_symfile_discard): Rearrange symbol file reading to divide
1809 the format-specific part from the format-independent part,
1810 leaving the format-independent part such as file name expansion
1811 and opening in symtab.c. This replaces
1812 partial_symbol_file_open and partial_symbol_file_read.
1813 Symbol_file_read, add_file, add_file_target_command,
1814 add_file_addr_command move to symtab.c. Pass an explicit
1815 "mainline" flag for when reading the main symbol table, rather
1816 than relying on the offset address to be zero or nonzero.
1818 (dbx_symfile_read): Don't allow void *'s to be printed as
1820 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1821 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1822 macro" debug version really work.
1823 (read_dbx_symtab): Remove unref'd parameter inclink.
1824 Avoid swapping N_SLINE symbols, for speed.
1825 Merge N_TEXT!N_EXT case with the other external symbol
1826 definitions' case. Add comments.
1827 (start_psymtab): Allocate the symfile name in the psymtab on
1828 the psymbol_obstack, rather than using the caller's storage.
1829 (end_psymtab): Only allocate a dependencies list if there are
1831 (psymtab_to_symtab_2): Use BFD when reopening file to read
1832 its symbols for real.
1833 (read_struct_type): Add FIXME comments where it needs work
1835 (read_huge_number): Add FIXME about overflows.
1836 (read_range_type): Add FIXME about comparing a long to 1<<32.
1838 * coffread.c: Minor changes to move things closer to the new
1839 regime with symtab.c and dbxread.c Major work is still needed
1842 * exec.c (exec_file_command): Remove old variables (see core.c
1844 (xfer_memory): If memory transfer is right at the end of a
1845 section, don't lose.
1847 * findvar.c (get_saved_register): If value is in a real
1848 register, LVAL is lval_register, not lval_memory.
1850 frame.h: Declare print_sel_frame and record_selected_frame.
1852 gdb-int.texinfo: New file, for GDB internals documentation.
1853 Very simple, unformatted doc of cleanups is there for now.
1855 gdbcore.h: Remove obsolete variables that described a.out
1856 section addresses and offsets. (See core.c above.)
1857 Declare fetch_core_registers and registers_fetched.
1859 getopt.c: Declare char *alloca(); even on SPARC.
1861 infcmd.c (run_command): Call target_kill rather than
1863 (step_command, next_command, stepi_command, nexti_command):
1864 Declare from_tty parameter even though we don't use it.
1865 (run_stack_dummy): argument BUFFER is a char array, not
1866 a pointer to REGISTER_TYPE.
1867 (finish_command): using_struct_return needed a value *,
1868 not a struct symbol *.
1870 * infptrace.c (child_xfer_memory): To avoid dependency on
1871 where sections are in memory, try PT_WRITE_D and if that fails,
1872 try PT_WRITE_I. Most Unixes don't care which you use.
1874 * infrun.c (step_resume_break_shadow): Change to array to
1875 match other breakpoint shadow storage.
1876 (clear_proceed_status): Pass address of bpstat to
1877 bpstat_clear, not the bpstat itself.
1878 (child_create_inferior): FIXME comment about if the child
1880 (start_inferior): Remove old function.
1881 (child_open): Use target_kill rather than kill_inferior.
1882 (wait_for_inferior): Ditto.
1883 (insert_step_breakpoint, remote_step_breakpoint): Use
1884 new step_resume_break_shadow.
1886 * inftarg.c (child_wait): If all child processes die,
1887 pretend that the one being waited for exited with signal 42.
1889 * main.c (command_line_input): When scanning for comments,
1890 don't coredump on unclosed quotes.
1891 (quit_command): Use target_kill rther than kill_inferior.
1892 (_initialize_main): Rename class_user from "user" to
1895 * printcmd.c (print_command_1): Initialize "fmt" if no format
1896 is specified by the user.
1897 (print_frame_args): Only add to args_printed if we are
1898 actually fetching args from the stack (avoiding undefined
1900 (_initialize_printcmd): Remove bogus \{ from string.
1902 * remote-eb.c (eb_open): Avoid coredump on no argument.
1904 * remote-nindy.c: Bring out of Intel environment into new
1905 target environment. Remove all conditional compilation on
1906 I80960. Massive hacking throughout.
1907 (nindy_xfer_inferior_memory): New routine stolen from
1909 (nindy_create_inferior): New routine pieced together, probably
1910 not quite working yet.
1911 (nindy_ops): New target_ops struct for nindy.
1913 * remote-vx.c: Use write_memory rather than target_write_memory
1914 to get error checking.
1915 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1917 (vx_create_inferior): Use target_terminal_ours...
1919 * signame.c (_initialize_signame): Always initialize, since
1920 we need the table for things other than psignal.
1922 * solib.c (solib_add): Use symbol_file_add, not add_file.
1923 (solib_address): Return boolean result rather than struct
1924 pointer which nobody else knows the type of.
1926 * sparc-tdep.c, valops.c: Use write_memory rather than
1927 target_write_memory, to get error checking.
1929 * stack.c (locals_info, catch_info, args_info,
1930 get_selected_block, frame_command, up_command): Use
1931 target_has_stack, rather than have_inferior_p or
1934 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1936 * symfile.h: New file, defining the interface between the
1937 generic and object-file-specific symbol reading code.
1939 * symtab.c: Move generic symbol-reading interface to symtab.c,
1940 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1941 table to map BFD targets to symbol-reading modules in GDB.
1942 Change index to strchr.
1943 (lookup_struct_elt_type): Use error() rather than hand-made
1944 simulations thereof.
1945 (lookup_partial_symbol): Speedup slightly when length == 0.
1946 (symbol_file_add): New function.
1947 (symbol_file_command): Call it.
1948 (symfile_open, symfile_init): New function.
1949 (add_file_target_command, add_file_addr_command): moved from
1952 * target.c (target_command): use target_kill.
1954 * target.h (target_files_info): Don't declare, never called
1957 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1958 files to determine stack end address.
1960 * valarith.c (value_x_binop, value_x_unop): Change error message
1961 to be more useful. Pass proper argument to value_struct_elt.
1963 * valops.c (value_assign): FIXME comment that long long
1964 bitfields will break here.
1966 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1967 Update `make saber_gdb' to work better.
1969 * TODO: A woman's work is never done.
1971 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1972 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1973 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1974 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1975 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1976 valops.c, valprint.c, exec.c: Lint.
1979 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1981 Continuing Intel 960 port merge of GDB.
1983 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1984 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1985 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1986 Wack over "make depend" so it handles files in subdirectories
1987 vx-share, nindy-share, bfd, and in the current directory.
1989 * blockframe.c (get_prev_frame_info): Remove fatal error
1990 if stack not defined.
1992 * core.c (core_open, core_detach): New functions that handle
1993 the old "core-file" command as "target core" and "detach" instead.
1994 (core_file_command): Call them.
1995 (core_xfer_memory): Use common routine xfer_memory.
1997 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
1998 dbxread now uses bfd for everything but symbol reading itself.
1999 BFD internals are used to drag out the relevant file offsets.
2000 (partial_symbol_file_open): Change args all around for BFD.
2002 * symtab.c: Rename "value" to "val" everywhere, so we can
2004 (symbol_file_command): New command, moved from dbxread.c
2005 and coffread.c. It uses BFD to read the file, then vectors
2006 based on its type, to dbx or coff symbol readers.
2007 * symtab.h: Extern a few vars for symbol_file_command.
2009 * target.h: Breakpoint takes a char * save area, not a char **.
2011 * valprint.c (val_print): When unpacking bitfields, offset
2012 the address in gdb of the value, if it is declared with a shorter
2013 type. Remove the last "runtime kludge test" of host byte order.
2015 * utils.c: Remove old my_bfd_read routine.
2017 * stack.c (frame_info): Use target_has_stack. Print program counter
2018 register's actual name rather than "pc", since it's called the
2019 "ip" (instruction pointer) on the i960 (sigh).
2021 * target.c (target_command): Add command for selecting a target
2022 type and calling its open routine. This is used for initiating
2023 communication with a particular target, in a generic way.
2025 * tm-i960.h: Update for modern gdb. Remove semicolons from
2026 various macros. Handle reading struct return convention, and
2027 error-out attempts to return structs with the "return" command.
2028 Be sure gdb doesn't think we know how to call functions in the
2031 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2032 to i960_xxx in lower case.
2033 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2034 not being defined yet.
2036 * remote.c (remote_open): Call start_remote to initialize
2037 wait_for_inferior during open.
2038 (remote_xfer_inferior_memory): Return length written rather
2041 * remote-vx.c (target_command -> vx_open): Use new generic
2043 * remote-eb.c, inftarg.c, exec.c: ditto.
2045 * infrun.c: Fix comments.
2046 (attach_program -> child_open): Use new generic target command.
2047 (wait_for_inferior): Clear saved register values before target_wait,
2048 so target_wait can set some of them if convenient.
2050 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2051 Return success indicator, not void.
2052 (child_xfer_memory): Avoid fetching initial word if we'll
2053 overwrite it anyway.
2055 * infcmd.c (attach_command): Use new generic target open routine.
2056 (_initialize_infcmd): Update doc on attach and detach commands.
2057 (do_registers_info): Merge in a byte-order problem as a FIXME
2060 * findvar.c (find_saved_register): Avoid problem in current frame.
2061 (read_relative_register): Ditto.
2062 (write_register): Convert byte order on the way out.
2064 * exec.c (file_command): Add.
2065 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2066 (xfer_memory): Common function between core_xfer_memory and

2073 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2074 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2076 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2078 Merge Intel 960 port of gdb, continuing...
2080 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2081 symbol_file_command): Pass from_tty arg to hush 'em up.
2083 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2084 Add magic numbers for 960 COFF format.
2086 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2088 Merge Intel 960 port of gdb, from Intel "1.2" release.

2107 "-se" switches as soon as they are encountered on the invocation line.
2109 Fri Apr 20 13:47:15 PDT 1990
2112 Thu Apr 19 09:54:28 PDT 1990
2113 Add 'reset' command.
2115 Wed Apr 18 09:48:07 PDT 1990
2116 After opening remote tty, wait for 1 second to go by without input
2117 from it before trying to talk to NINDY (fixes problems with the
2118 Heurikon HK80/V960E).
2120 Mon Apr 4 16:33:05 PDT 1990
2121 Some output was not being suppressed in 'batch' mode.
2123 Thu Mar 22 15:31:11 PST 1990
2124 Ask user if old symbol table should be deleted when new file is
2127 Allow user to run a program downloaded before gdb960 was brought up.
2129 Correct "exec-file" help message for i80960 context.

2154 Mon Oct 2 15:56:31 PDT 1989
2156 Added 960CA disassembly support.
2158 To simplify maintenance:
2159 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2161 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2162 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2163 - made disassembly interface identical to that in gdmp960.
2167 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2169 * target.h: Allow targets to stack. Add target_has_memory,
2170 _registers, etc. Restructure memory access and "info files"
2171 to walk the target stack.
2172 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2173 target.c: Change tables to match target.h.
2174 * inflow.c (child_mourn_inferior): pop child_ops.
2175 (generic_mourn_inferior): Use new has_stack flag.
2176 * infptrace.c (child_xfer_memory): New memory regime.
2177 * inftarg.c (child_files_info): New "info files" regime.
2178 * remote-eb.c: New memory regime, new info files.
2179 * remote-vx.c: New memory regime, new info files. Now use
2180 separate targets for VxWorks attachment to machine, and
2181 actually running a process under VxWorks, since one has
2182 stack & execution & regs and the other doesn't.
2183 * remote.c: New memory regime, new info files.
2184 * sparc-xdep.c (fetch_core-registers): New memory regime.
2185 * target.c: New routines and support for stacked targets,
2186 new memory regime, new info files regime.
2189 Generalize section handling for an arbitrary number of sections,
2190 including use of the new BFD (binary file) library.
2191 * gdbcore.h: Add struct section_table.
2192 * exec.c (build_section_table): Iterate all sections and
2193 record what gdb needs to know about them.
2194 (exec_command): Use it.
2195 (exec_xfer_memory): Use the table.
2196 (exec_files_info): Print the table.
2197 * core.c (core_file_command, core_xfer_memory, core_files_info):
2199 * source.c (find_source_lines): Use bfd_get_mtime.
2200 * dbxread.c: Quick changes to make it compile with new BFD.
2201 * utils.c (error): Avoid using bfd_error in generic routines.
2203 * core.c (core_fetch_registers): Get from the ".regs" section of
2205 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2207 * inferior.h (attach_flag): Export.
2208 * infcmd.c (run_command): use new target_create_inferior.
2209 * infrun.c (child_create_inferior): Don't return result.
2210 * Makefile.dist (VERSION): 3.91.4.
2212 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2214 * breakpoint.c (bpstat_num): Handle breakpoints which have
2215 since been deleted, such as temporary breakpoints.
2216 infcmd.c (program_info): ditto.
2218 * core.c (core_file_command): Display the frame where the core
2223 * remote-vx.c (target_command): Merge in target command from
2224 targ-vx.c. A few other cleanups.
2226 * TODO, Projects: Lots more stuff to do...
2228 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2230 Massive changes to wall off the remote-debugging interface
2231 behind a function vector. The port to handle VxWorks targets
2232 is also part of this.
2234 All files: Replace references to renamed functions,
2235 remove references to remote_debugging, remove references to
2236 have_include_file, have_core_file in favor of target_has_stack,
2237 target_has_memory, etc.
2239 * Modularize the breakpoint interface.
2240 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2241 a breakpoint instruction.
2242 breakpoint.c: struct breakpoint's shadow_contents now sized as
2244 (insert_breakpoints): Vector to target to install breakpoints.
2245 (remove_breakpoints): Vector to target here too.
2246 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2247 sparc-tdep.c (single_step): Use new breakpoint interface for
2248 the single-step breakpoints.
2249 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2250 New file, contains routines to insert and remove breakpoints by
2251 reading out the old contents and later replacing them. This is
2252 how ptrace breakpoints work, and many remote systems as well.
2254 * tm-vxworks68.h: New config file, overrides a few things for
2255 Wind River's preferences.
2257 * target.h: New file, for transfer vector used to talk to the
2258 inferior (child, attached, core, exec, remote, etc). All accesses
2259 to the thing being debugged should come through these vectors.
2260 target.c: New file, routines to handle transfer vector.
2261 (various files): Add transfer vectors XXX_ops for the various
2262 targets and pseudo-targets (core files, etc) we support.
2264 * breakpoint.c (bpstat_stop_status): Further explorations of
2265 watchpoints and why things don't work all the time.
2266 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2268 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2269 the local gdbinit if it doesn't already have it.
2271 * core.c (core_ops): add and install.
2272 Allow core debugging without exec file.
2274 * dbxread.c (free_and_init_header_files): Merge two fns.
2275 (end_symtab): Free named symbol table when a new version comes in.
2276 (read_dbx_symtab): Relocate all kinds of symbols with base
2277 address. First step toward handling different text, data, bss
2279 (add_file_addr_command): Renamed add_file_command.
2280 (add_file_command): Vector to remote handler.
2281 Add "load" as an alias for "add-file" command.
2283 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2284 non-returning functions.
2286 * exec.c: Add exec_ops, and push it as a target when an exec
2289 * infcmd.c (run_command): Pass executable file name and arg list
2290 separately when starting an inferior. Permit "run" when no exec
2291 file is specified, for VxWorks.
2292 (detach_command): Move to child_detach in inftarg.c.
2294 * inftarg.c: New file. Unix-child-specific routines, and the
2295 child_ops structure.
2297 * inferior.h (registers): Export "registers" as the way for
2298 target dependent register handlers to find gdb's local copy of
2299 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2300 since it is now used by places that want wait_for_inferior to
2301 handle the grunge but want to see every trap from the inferior.
2303 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2304 Eliminate remote_debugging hooks in terminal handling.
2306 * infrun.c: Replace start_inferior with child_create_inferior.
2307 Move all the hair of Unix shells and ptrace idiosyncracies into
2308 child_create_inferior, so remote handlers don't have to deal.
2309 Remove running_in_shell. Rename stop_after_attach to
2310 stop_soon_quietly, and use it in a few other places where we want
2311 to just call wait_for_inferior and get control back on the first
2312 trap. trap_expected now never takes a value > 1.
2313 (init_wait_for_inferior): Initialize static vars when a new
2316 main.c (gdbinit): Add new hook for .gdbinit file name, let
2317 it be overridden by config files as GDBINIT_FILENAME.
2318 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2319 Both of these are used for VxWorks gdb.
2321 mcheck.c: rename include file "gmalloc.c" to avoid problems
2322 with system include file "malloc.c".
2324 param-no-tm.h: New include file, same as param.h but does not
2325 include the default "tm.h" file. This is used in files where
2326 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2328 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2330 remote-vx.c: New file, VxWorks remote debugging support. Uses
2331 RPC routines that are shared with the target system, in directory
2334 remote.c: Vectorize remote interface.
2336 source.c: Globalize source_path, and make an alias "l" for "list"
2337 since we now have the "load" command.
2339 sparc-xdep.c: Use new param-no-tm.h.
2341 symmisc.c (free_named_symtab): Add new function from Wind River.
2342 However, ifdef it out for now while we think about what it should
2345 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2347 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2348 non-Unix-children handle this with their own code in the target
2351 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2352 source and target lists. Add vx-share to default list of include
2353 directories. Add new files to src and target lists: mem-break,
2354 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2355 ${srcdir} versions of munch and createtags are used.
2357 * valops.c (find_function_addr): Split out of call_function.
2358 (call_function_by_hand): Rename call_function; this function
2359 calls functions in the target by laboriously patching the target
2360 word-by-word with the right stack, args, regs, etc.
2363 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2365 Handle AMD 29000 a bit better.
2367 * remote-eb.c (readchar): Mask received char log to make it readable.
2368 (remote_start): Pass arguments down to executing program.
2369 Make startaddr unsigned.
2370 infrun.c (start_inferior): Accept args, pass them to
2372 infcmd.c (run_command): Pass args down to start_inferior.
2374 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2375 the target object file format.
2376 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2378 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2379 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2381 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2383 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2384 * TODO: We did a few things, we have more to do though.
2386 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2387 * inflow.c (inferior_died): Clear deferred stores.
2389 * Debug problems with dummy frames and calls to the inferior.
2390 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2391 * sparc-tdep.c (do_restore_insn): Simplify.
2392 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2393 (sparc_push_dummy_frame): Simplify and fix what we push.
2394 (sparc_pop_frame): Slightly more hair here, deciding whether
2395 we are restoring a saved PC or returning to a return address in %i7.
2396 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2398 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2399 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2400 * obstack.h (chunkfun): ditto.
2401 * defs.h (xmalloc, xrealloc): ditto
2403 * utils.c (quit): Grab the terminal from the child if necessary.
2405 * inflow.c (term_status_command): Rename to term_info, change
2408 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2409 (is_delayed_branch): Speed up.
2410 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2411 Still missing some float ops, and needs testing.
2413 * Support for input and output radixes other than base 10
2414 * defs.h (input_radix, output_radix): Declare.
2415 * expread.y (yyparse, parse_number): Handle changes of input
2416 radix, and ambiguous names-or-numbers in radixes >10.
2417 * printcmd.c (print_scalar_formatted): Print formatted hex
2418 numbers in varying column widths.
2419 * valprint.c (val_print): Use output_format to print scalar ints.
2420 (set_input_radix, set_output_radix, set_radix): Create.
2421 (set_output_radix): Set output_format from output_radix.
2422 (_initialize_valprint): add `set radix' but leave the others off.
2424 * main.c (execute_command): Let stupid questions be turned off.
2425 (_initialize_main): Handle "set stupidity", etc.
2427 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2428 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2430 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2432 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2433 bfd stuff is still screwed up, but with some manual work, it
2436 * breakpoint.c (bpstat_do_actions): Start over if a command
2437 proceeds the inferior, since the inferior will have stopped and
2438 will need to have its new stop-actions taken care of.
2440 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2441 compiler fits, simplify it.
2443 * gdb.texinfo (directory command): Doc new dir command.
2444 source.c (directory_command): "dir" now puts things on the front
2445 of the path, moves dups up front, and handles multiple names
2446 on the command line, inserting each one in order. It also
2447 blows away cached line and full_filename info.
2449 * stack.c (backtrace_command): Skip "more stack frames follow"
2452 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2453 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2454 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2455 The only odd one was Gould NP1, which had defined vprintf to
2459 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2460 variable, inspect_it.
2461 valprint.c (print_string, val_print): Use the global inspect_it
2462 to indicate whether to print in Epoch style or normal style.
2464 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2466 * printcmd.c (call_command): add an alias for the "print" command
2467 which runs expressions and doesn't print the result if void.
2468 (print_command_1): implement it.
2470 * command.c: Remove #if 0'd code. Initialize all the fields
2471 in add_cmd (). Rename do_nothing_command to
2472 not_just_help_class_command, and make it externally visible.
2473 command.h: add user_commands to struct.
2474 * main.c (define_command): Don't overload c->function with a char
2475 string as well as a function pointer.
2477 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2478 calling convention of value_struct_elt () that got dropped in
2481 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2482 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2484 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2486 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2487 until a good time (e.g. when we are about to run the child),
2488 saving ptrace calls.
2489 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2490 * tm-sparc.h: define DO_DEFERRED_STORES.
2492 * sparc-xdep.c (store_inferior_registers): when storing float
2493 registers, don't store stack regs too. When storing the SP,
2494 however, DO store the stack regs too. This fixes a bug in which
2495 the dummy frame is not recognized when a call_function finishes,
2496 because its frame pointer (in the stack regs) was never
2498 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2499 even though we don't know how to read them from an inferior.
2500 valops.c (call_function): Comment about storing SP.
2502 * infrun.c (save_inferior_status): Save away the original bpstat
2503 chain so it can be restored later. Install the copied version for
2504 use by whoever saved the status. It will be blow away by
2505 restore_inferior_status, and the original chain restored. This is
2506 important for people who have pointers into the original.
2508 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2509 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2510 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2513 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2515 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2516 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2517 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2519 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2521 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2522 Store the baseclasses in a type struct starting from array element
2523 0 rather than from the unusual array element 1.
2525 dbxread.c: the above.
2526 (virtual_context): Add
2527 Read new debug information about which virtual function table
2528 a virtual function is from, and store it in fn_field.fcontext.
2530 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2531 TYPE_FN_FIELD_STATIC_P.
2533 symtab.c: the above.
2534 valops.c: the above. Handle pointer casts of object *'s.
2535 (search_struct_method): Add.
2536 (value_struct_elt): First arg is now a pointer to a value, and is
2539 valprint.c: the above.
2540 values.c (value_virtual_fn_field): Add type arg. Handle
2541 offsetting to the proper object when calling virtual fns.
2543 (baseclass_addr): Add valuep arg.
2545 * README: Document the current state of BFD config (missing).
2546 * TODO, ChangeLog, Makefile.dist: Roll version.
2547 * WHATS.NEW: Add summary of changes since 3.5.
2549 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2551 * dbxread.c (read_struct_type): Clear bit vectors whenever
2553 symtab.c (B_CLRALL): define.
2555 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2556 using == rather than =. Huh... This fixes the dreaded problem
2557 wherein builtin_type_int becomes TYPE_CODE_FLT.
2559 * core.c (info_files): Show the inferior pid.
2561 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2562 already knows how to look in the source directory.
2564 * Remove psymtab hair from many places. Remove duplicated code
2565 for searching symbol tables. Hide psymtabs from most places.
2566 Make it fast to get from a psymtab to its symtab.
2568 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2569 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2570 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2571 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2572 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2573 new symtab completely. New psymtabs get symtab pointer
2574 initialized to zero. Remove MI warning printf.
2575 symtab.h: Comments. Add psymtab to symtab pointer.
2576 (PSYMTAB_TO_SYMTAB): New macro.
2577 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2578 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2580 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2582 (print_frame_info): Avoid special-casing symbols that have not yet
2585 * source.c (open_source_file): Quick path if we have already
2586 located the source file by its full name.
2588 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2589 find_pc_psymtab. When a name is found in the misc function
2590 vector, search the symbol table for its mangled name, not the
2591 name that the user typed.
2593 * bfd.h: Fix missing comment terminators, make #endifs match.
2595 * valarith.c (value_less): Handle unsigned int comparisons.
2596 Add FIXME about pointer compares, which assume host and target
2597 pointers are the same.
2599 * command.c (do_nothing_command): lint
2600 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2601 fix comments on debug symbol format for visibility. Actually set
2602 visibility of symbols.
2603 main.c (echo_command): lint; use <readline/history.h>.
2604 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2605 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2606 pointing past end of allocated memory; saber complains.
2607 obstack.h: Declare the external functions that we use.
2608 valarith.h: use <string.h>
2609 solib.c (solib_add): lint.
2611 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2613 * main.c (initialize_main): Default info_verbose to off, now that
2614 symbol reading is fast.
2615 (quit_command): Avoid clobbering exec_bfd while quitting.
2617 * Initial BFD (binary file diddling library) merger:
2618 coffread.c: Change AOUTHDR to struct exe_hdr.
2620 core.c: initialize initialized data at compile time.
2621 (core_file_command): Move from coredep.c, convert to bfd.
2622 (xfer_core_file): Convert to bfd.
2623 exec.c (exec_file_command): use bfd routines.
2625 mips-tdep.c: Remove exec_file_command and friends.
2628 * coredep.c: (fetch_core_registers) Convert core_file_command to
2629 fetch_core_registers.
2630 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2632 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2633 (my_bfd_read): More bogosity, which I don't think we call.
2634 (program_name): Remove this atrocity asap!
2636 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2639 values.c: allocate_repeat_value was not clearing the
2640 optimized_out field.
2641 (value_static_field): minor stylistic fix (wrong macro was used).
2642 valops.c (value_struct_elt_for_address): didn't work for C++
2645 * signame.c (_initialize_signame): Initialize signal names once.
2647 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2648 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2649 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2651 * remote-eb.c: Support user-settable baud rates on the serial port.
2653 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2655 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2657 * tconfig/sun3os4: Remove warning about native assembler,
2658 since it also occurs in the xconfig file.
2660 * findvar.c (registers): Allocate some slop after `registers'
2661 to prevent stray accesses from trashing the next variable.
2663 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2664 on the sun-3, by changing the #ifdef from `sun3' (which is not
2665 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2666 vars, which happened to follow `registers' in the executable.
2668 * readline/history.c (history_search): Heed gcc-2's advice
2669 and parenthesize && inside ||).
2671 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2672 tm-29k.c: Insert FSF copyright headers.
2674 * remote-eb.c: Better comments.
2676 * Makefile.dist: Update to 3.91.6.
2677 * TODO: note PREPARE_TO_STORE problem.
2679 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2681 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2683 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2685 * infrun.c (wait_for_inferior, at end): Don't set up
2686 prev_* if the inferior no longer exists.
2688 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2689 CANNOT_EXECUTE_STACK.
2690 valops.c (call_function): Use it.
2692 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2694 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2695 infrun.c (wait_for_inferior, 2 places): Use it.
2697 * values.c (value_being_returned): Only use
2698 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2700 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2701 right thing for remote-eb.c.
2703 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2704 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2706 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2707 (FRAME_FIND_SAVED_REGS).
2709 * findvar.c ({fetch,store}_registers): Check for
2710 REMOTE_{FETCH_STORE}_REGISTER macro.
2712 * findvar.c (get_saved_register): Add argument lval and
2713 change meaning of argument addr.
2714 findvar.c: Change calls to get_saved_register to reflect
2715 new calling convention.
2716 valops.c (value_assign): Use get_saved_register instead of
2717 find_saved_register.
2719 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2721 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2722 an (uninitialized) pointer to one. Use "&" when passing it
2725 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2727 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2730 * coffread.c (symbol_file_command): Put semicolon after
2732 Put safe_to_init_tdesc_context in #if defined (TDESC).
2733 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2734 coffread.c: #include <sys/stat.h>.
2735 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2736 Add missing ')' in check for "lc%" and friends. Remove
2738 Declare read_one_sym() at top of file.
2739 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2740 MC68WRMAGIC can have the same value without causing a duplicate
2743 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2745 * Allow a Makefile to be built without building the
2746 tm and xm file links that screw up builds in subdirectories.
2747 This is done with `config.gdb none', then you can do things
2748 like `make gdb.tar.Z'.
2749 * tconfig/none: Config file for no target system
2750 * xconfig/none: Config file for no host system
2751 * config.gdb: If no TM or XM files are called out by the
2752 host or target file, don't make links for them.
2754 * cplus-dem.c: Add documentation.
2756 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2757 simple error, so the user's gdb doesn't crash due to some object
2758 file problem (e.g. somebody is rebuilding the file out from under
2761 * printcmd.c (print_address_symbolic): demangle the symbol.
2763 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2764 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2765 (alldeps.mak): sort and uniq all results from this; duplicates
2766 hose gdb.tar.Z link building. Remove RCS files from
2767 tconfig and xconfig. Add config files for sun386. Add
2768 a few odd files to OTHERS and HFILES.
2770 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2772 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2773 Roll version number to 3.91.5. Make lint work in bindir.
2775 * README: Document cross-debugging and new file structure.
2777 * blockframe.c: Lint. Include "value.h" to declare read_register.
2778 (find_pc_partial_function): remove duplicate line.
2780 * command.h: Lint. Declare error_no_arg and dont_repeat.
2782 * tm-news.h: Remove inadvertently duplicated stuff.
2784 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2785 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2787 * config.gdb: Allow `config.gdb host target' form. Clean
2788 up previous change that printed bogus messages when you just said
2791 * core.c: #include "command.h" for lint.
2794 * main.c: Remove some casts of enums. Lint.
2801 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2803 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2804 read it from memory. This will allow us to save ptrace calls
2805 eventually. Changed caller single_step too.
2807 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2808 that we aren't going to use, saving many ptrace calls, especially
2809 when watchpointing or single stepping. Use some #define's for
2811 (store_inferior_registers): Ditto.
2812 (core_file_command): Use some #define's for constants.
2814 * tm-sparc.h: Add #define's for some register numbers, so we
2815 can eliminate the use of random constants in sparc-xdep.c.
2817 * stack.c (frame_command, print_frame_info, up_command,
2818 down_command) Remove frame_changed, since it
2819 causes a bug and doesn't seem to do anything useful. In some
2820 places it was used as a flag, in others as a stack level (?).
2822 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2823 default is to use the portable (vprintf) version rather than the
2825 * xm-news.h (MISSING_VPRINTF): Add.
2827 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2829 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2831 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2832 about linking debugged programs -Bstatic in the sun?os4 config
2833 files in tconfig and xconfig subdirectories.
2835 * main.c (main): Remove unreached exit(0) now that we exit
2838 * Create TODO file for online bug list. There are too many
2839 "little" bugs to keep track of on paper.
2842 rather than kingdon@ai.
2844 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2846 * Makefile.dist (VERSION): 3.91.4 now.
2848 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2849 (condense_misc_bunches): Add sanity check that misc_count is
2850 the same as the number of symbols in the bunch.
2852 * coffread.c: rename init_misc_bunches. Pass an argument
2853 to condense_misc_bunches (a zero).
2855 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2856 every time we are called; don't rely on our caller to do it.
2857 (add_file): Remove call to init_misc_bunches.
2859 * mipsread.c: Only warn, don't error, if unknown symbol types.
2860 This keeps an old gdb from falling on its face if it sees newly
2861 extended symbol info. Rename init_misc_bunches.
2863 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2865 * Merge in changes from Per Bothner for DECstations and other
2866 MIPS stuff. The rest is Bothner speaking:
2868 The next message is a merger of Alessando Forin's mips port with
2869 mine. I've tried to use my good if biased judgment to get
2870 the best of both. It *does* need testing.
2872 Some of the changes are general, *not* mips-specific.
2875 Didn't believe in little-endian bit order.
2876 There are still inconsistencies about whether flags
2877 like BITS_BIG_ENDIAN are integer (#if ...) or
2878 boolean (#ifdef ...). I tried to paper over them.
2880 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2881 Moved some misc_function code that was common to
2882 {dbx,coff,mips}read.c to symtab.c.
2883 In the process, I think I cleaned things up a bit.
2884 At the same time, moved obsavestring and obconcat to symtab.c.
2887 Removed obsolete condense_addl_misc_bunches (use
2888 condense_misc_bunches(1) instead).
2891 Needed to include <sys/dir>, at least on DECstations.
2893 valops.c, mips-tdep.c, tm-mips.h:
2894 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2895 conventions (when STACK_ALIGN is insufficient).
2896 Needed on mips, where doubles need 8-byte alignment,
2897 but ints only need 4.
2900 Removed cruft that was not being used.
2904 Print $ before register-names (I think that makes things a little
2906 Never print two instructions, even if one delays.
2907 Removed hex-disassemble set_cmd. (This is not mips-specific,
2908 so I think the argument is whether it is generally worthwhile or not.
2909 I'm inclined to think not, given how easy it is to
2910 convert between radixes in gdb.)
2913 This is basically Alessando's code.
2914 It doesn't use obstacks; I changed it to use obstacks
2915 in a few minor places where using malloc causes a
2916 memory leak. (Probably, more places could/should be changed.)
2917 I added record_misc_function where it was missing.
2918 In symbol_file_command and add_file_command, I tried
2919 to make the code consistent with more recent versions.
2920 Minor sylistic changes in parse_procedure.
2921 Make a .gdbinfo. psuedo-symbol point back to the real
2922 procedure symbol (using the isym field).
2925 This is basically from my port, but with a lot of details
2926 and a number of routines merged in from Alessando's version.
2927 I basically used my code "raw" backtrace (use heuristics
2928 from the actual code, rather than symbol table info) - though
2929 the idea is Alessandro's. I feel my code is a little cleaner
2930 here, particularly in being a little more flexible, such as being
2931 able to handle gcc-produced code (which it now can).
2932 It also doesn't do frame caching (which is not useful
2933 more recent gdb versions).
2934 I also used my code for push_/pop_dummy, more or less.
2935 I tried to incorporate AF's code for testing sigtramp
2936 while backtracing; I probably got it wrong.
2937 Added mips_print_register, which tries to scrunch as much
2938 information as possible on a screen...
2939 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2940 under mips-pinsn.c), I don't see anything mips-specific here,
2941 and I don't see it being all that useful anyway.
2944 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2945 Use more register names (rather than hard-cases numbers).
2947 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2949 * Hack up 3.90.11 changes:
2951 * Makefile.dist (depend): parameterize $(GCC).
2952 Add solib.c and solib.o.
2953 (readline): Fix vpath for both absolute or relative SRCDIR.
2956 Also, let the part I didn't understand at least compile so
2957 I can test the rest. FIXME.
2959 * dbxread.c: Fix thinko using strcmp.
2960 (init_psymbol_list): declare static.
2961 (partial_symbol_file_open): Comment cleanups better, avoid
2962 cleaning up the string table since the caller will do that.
2963 Move the stat for mod time into symbol_file_command, temporarily.
2964 (There should be a mod time for each symbol file, eventually,
2965 to control its rereading. FIXME.)
2967 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2968 SunOS, which gives error for shared libs otherwise. (From
2969 Schaefer, probably FIXME needs work for portability.)
2971 * solib.c: Move #include "param.h" to work.
2972 Lowercase all the Uppercase Letters In the Messages.
2973 (find_solib): Clean up inferior_so_name for debug printouts.
2974 Allow no argument, to mean all shared libraries.
2976 * symmisc.c: include param.h to get CLEAR_SOLIB.
2978 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

3024 Take code which is shared between symbol_file_command and
3025 add_file_command and put it into partial_symbol_file_{open,read}.
3026 Split add_file_command into add_file_command and add_file.
3027 Make psymtab_to_symtab read in the string table if the file
3029 Two new parameters to read_dbx_symtab and start_psymtab.

3068 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3070 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3072 config.gdb: If srcdir != ., create readline directory and
3073 copy a makefile into it.
3075 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3076 consistency with POSIX.
3078 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3079 when we exit its exp_valid_block.
3081 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3083 * Makefile.dist: Bump version to 3.91.3.
3085 * Clean up handling of breakpoint commands (somewhat).
3086 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3088 inferior.h: Add breakpoint_proceeded to inferior status struct
3089 and globals; save it and restore it.
3090 (clear_breakpoint_commands): Cleanup, remove old #define.
3092 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3093 (save_inferior_status, restore_inferior_status): handle it also.
3094 (proceed): Remove earlier code that set breakpoint_proceeded.
3095 It is now set only in clear_proceed_status.
3096 (clear_proceed_status): Cleanup, use bpstat_clear rather
3097 than clear_breakpoint_commands. No callers need the stop_bpstat
3098 between clear_proceed_status and proceed.
3100 infcmd.c: Add breakpoint_proceeded definition and comment.
3101 (cont_command, jump_command, signal_command): Move call to
3102 clear_proceed_status right next to call to proceed.
3104 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3105 caller's argument while running down the chain of breakpoints.
3106 Use new variable "breakpoint_proceeded" to determine when
3107 a command that it executes moves the inferior past the
3109 (bpstat_clear): Handle NULL argument.
3110 (bpstat_clear_actions): Avoid useless call to
3111 breakpoint_auto_delete.
3112 (delete_breakpoint): Clean up bpstat's that are pointing to
3113 the deleted breakpoint from the stop_bpstat chain.
3114 (breakpoint_auto_delete): Simplify.
3116 * Clean up handling of EOF, error on stdin, etc. This was
3117 prompted by a network problem that caused gdb to go into an
3118 infinite loop filling up its malloc'd memory.
3120 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3121 not clear_breakpoints_commands, which is now gone.
3122 (main): If command_loop returns (e.g. from EOF on stdin), do
3123 a quit_command (looping back to command_loop if quit_command
3124 doesn't really quit).
3125 (command_loop): check result from command_line_input and
3126 exit if it returns NULL, rather than passing the NULL to
3128 (gdb_readline): Free malloc'd result space before returning
3131 * utils.c (query): Handle C-d to mean "yes", just as if the
3132 input was not a terminal. Also avoid infinite loop if EOF
3133 occurs in mid-input-line before newline. This allows
3134 query to be used at EOF on stdin with reasonable results.
3136 * infrun.c (proceed): Set breakpoint_proceeded.
3138 * values.c (value_as_long): Avoid infinite recursion for enums.
3139 (_initialize_values): Fix typo in help msg (kingdon).
3141 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3142 RL_LIB for linking. This allows -lreadline for linking
3143 and nothing for dependencies, once readline is a real library.
3145 * config.gdb: Jim Kingdon: give useful error message if the
3146 host or target type is not recognized.
3148 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3149 it just defines it. Dumb, but deal with it.
3151 * Jim Kingdon suggests:
3152 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3154 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3156 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3158 * Clean up Bothner's changes.
3160 * blockframe.c (clear_pc_function_cache): New function.
3161 * blockframe.c: remake cache_pc_function_* static.
3162 * dbxread.c (symbol_file_command): remove references to
3163 cache_pc_function_* variables.
3164 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3165 * printcmd.c: Avoid kludging a global variable (addressprint)
3166 to avoid printing the address of a string twice. Instead,
3167 pass the format letter 's' down low enough that it can be seen
3168 to avoid this problem.
3169 (print_formatted): Pass format arg to value_print.
3170 (restore_addressprint): Remove function.
3171 (do_examine): Avoid hacking addressprint, cleanups and such.
3172 (print_frame_args): Add a comment to a Bothner change.
3173 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3174 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3175 to wipe out the values cached in blockframe.c.
3176 * symtab.c (find_method): Add comment saying how big you must
3177 allocate to be "big enough". Per being terse again.
3178 * valprint.c (val_print): Handle format letter "s" to print
3179 strings without addresses. Add comment to vtbl printing code
3180 which casts with wild abandon. Rearrange reference-printing
3182 @0xaddr: value (print w/addressprint)
3183 value (print w/~addressprint)
3184 @0xaddr (parameter lists w/addressprint)
3185 or nothing (parameter lists w/o addressprint)
3187 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3189 * Merge more changes from Per Bothner:
3191 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3192 annoying) that I tried to improve it. Here are my suggestions.
3194 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3197 Do automatic de-reference when taking the address of a reference.
3199 Don't deref_ref when printing parameter lists.
3201 More attempts at treating refernences properly.
3203 In val_print, if deref_ref==0, don't print dangling " = ".
3205 Add COERCE_REF macro, which de-references an REF.
3207 * Merge changes from Per Bothner:
3209 * Fixed (Sony news)-specific configuration problems.
3210 * Fixed other problems with using vanilla pcc and libc (enum problems;
3211 assumption that vsprintf exists).
3212 * Some major speed-ups (finc_pc_partial_function now caches a match;
3213 parsing avoids duplicate symbol_lookup calls).
3214 * Changed handling of baseclasses (no longer use baseclasses field
3215 of struct type, use the first n_baseclasses fields instead).
3216 * Various minor changes/fixes, most C++-related.
3219 Cache the most previous match from find_pc_partial_function.
3220 (Save both low and high ends of matching function's pc range.)
3221 This speeds up the loop of infrun.c:wait_for_inferior quite
3222 a bit, and makes step/next commands much zippier.
3224 Added an enum->int cast (otherwise, some compilers barf).
3226 No longer set baseclass offset to 0, since multiple
3227 inheritance now mostly works.
3228 Added a number of casts, to shut up compiler warnings
3229 (after stabs where made enums, not ints).
3230 When discarding a symbol table (in symbol_file_command),
3231 must clear the cache introduced in blockframe.c.
3232 Don't convert $vtbl_ptr_type to vtbl any more.
3233 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3234 Mask off sign bit emitted by g++ for virtual table offset.
3235 Set voffset to -1 (not 1) for static member functions.
3237 Changed parsing/lexing of names to avoid doing symbol lookup twice
3238 (once when lexing to determine symbol class, once for real).
3239 Now only call symbol_lookup once. Fields of 'this' win especially big.
3241 Subpress printing addr twice in the case of 'x/s addr'.
3243 lookup_basetype_type is no longer used.
3244 Add find_methods as recursive helper function to decode_line_1.
3245 This allows multiple inheritance to work.
3246 Also, once one or more matches has been found, do not look in
3247 base-classes. (Baseclass methods would be overridden, anyway.)
3249 Removed baseclasses array in struct type.
3250 Instead of using baseclasses[i], use fields[i-1].
3251 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3252 Changed sign convention of voffset (previous was inconsistent).
3254 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3256 Used to assume existence of vsprintf. Re-written to not need it
3257 if HAVE_VPRINTF is undefined.
3259 typecmp was too pessimistic. Made it less so.
3261 Don't print space after address.
3262 If vtable points to a misc symbol (with 0 offset), print it,
3263 since that indicates the actual class of the object.
3264 Changed ype_print_derivation_info to use new inheritance
3265 scheme (without baseclasses vector).
3267 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3268 Also, changes needed because TYPE_BASECLASSES were removed.
3270 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3272 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3275 If there is no path set, and the symbols don't indicate what directory
3276 a file was compiled in, look in the current directory. But either
3277 a path or a known compilation directory will prevent this.
3280 Three independent bug fixes:
3281 * Remove the #if 0 block that breaks some stuff.
3282 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3283 adapt gdb to either SunOS 4.0.* or 4.1.
3284 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3287 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3290 (type_print) Demangle the name being printed.
3291 (type_print_base) Handle botched demangling without coredump (tiemann).
3294 (check_stub_method): Document routine.
3295 (tiemann) fix bug for no-arg functions
3296 Avoid clobbering beyond end of malloc'd storage.
3297 Terminate the argument list properly.
3301 * Changes merged by John Gilmore:
3304 In breakpoint_1, use new print_address_symbolic instead
3305 of find_pc_partial_function. (This forces use of assembler-level
3306 addresses, and avoids misleading non-mangled source-level names.)
3308 Generalize ansi argument such that -1 means skip arglist totally.
3309 Removed global variable print_ansi_qualifiers (which made
3310 code non-reentrant), in favor of extra explicit arguments
3311 to internal routines.
3313 Add new helper function print_address_symbolic.
3314 Use find_pc_misc_function instead of find_pc_partial_function
3315 (since we want assembler-level symbols here).
3317 Print unknown function as just "f (...)", not "f (...) (...)".
3318 Use new fputs_demangled explicitly.
3320 Fixed a typing violation (problem: value.h cannot be imported
3321 without renaming many variable in this file).
3322 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3323 decode_line_1: Moved forward some never-reached code.
3324 Made decode_line_2 skip function prologues correctly.
3326 fputs_filtered should not demangle by default.
3327 Add new fputs_demangled to demangle on demand..
3329 Change value_struct_elt to use value_primitive_field (using recursive
3330 utility function search_struct_field). This allows foo.bar to work
3331 for multiple inheritance (so far only for data fields).
3332 Change check_field in the same way (recursive helper function
3333 to support multiple inheritance).
3334 (Note: there are more of these problems that I haven't fixed.
3335 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3336 value_of_this: 'this' symbol name is now just "this", note "$this".
3338 Don't print static members.
3339 Avoid printing "members of <type>" if there are none.
3340 Simplified type_print_derivation_info by merging duplicate code.
3341 Remove useless blank lines in type_print_base (ptype command).
3343 Added declaration of new routine value_primitive_field.
3345 Added value_primitive_field which is generalized version of
3346 value_field that can handle multiple inheritance (non-zero offsets etc).
3347 Re-implemented value_field to call value_primitive_field.
3349 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3351 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3352 delete the whole environment. Karl Berry reported the bug.
3353 * source.c - fix openp to avoid //'s in filenames, which
3354 trigger an Emacs bug causing it to not be able to find files
3355 when running gdb in a window.
3356 * dbxread.c - zap the #if 0 that botches the add-file code.
3357 It seems to work a lot better without all the code commented out.
3359 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3361 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3364 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3366 * Makefile - added a ${CFLAGS} to a couple of entries,
3367 added remote-sa.sparc.c
3368 * added remote.sa-sparc.c, a modification of remote.c
3369 which conducts a dialog directly with the SparcStation prom.
3370 * breakpoint.c, infrun.c, sparcdep.c added
3371 remote_insert_breakpoint(), and remote_remove_breakpoint()
3372 to breakpoint.c instead of directly writing breakpoint instructions.
3373 * sparcdep.c on remote_debugging,there is no need
3374 to remove signle step breakpoint instructions.
3375 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3377 * printcmd.c - epoch interface sends lisp expressions to open up
3378 epoch windows on inspection.
3379 * valprint.c - added arrayprint, and addressprint and made adding
3380 format controls easier
3381 * wait.h added a couple of undef's because we were getting
3382 complaints about WSTOPSIG and WTERMSIG begin redefined.
3385 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3387 * symtab.c (decode_line_1): Add support for handling method stubs
3388 in the type information.
3390 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3392 * values.c (baseclass_addr): Run loop from INDEX+1 to
3393 N_BASECLASSES; otherwise, we can still get into a loop.
3394 @@ This should be restructured to use a cleaner search strategy.
3396 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3398 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3399 abbreviation "Tt" for tags which have the same name as their
3402 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3404 * symtab.c (list_symbols): add ability to set breakpoints on all
3405 the functions which match a particular regular expression.
3407 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3409 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3410 should print ANSI qualifiers (such as `const' and `volatile').
3411 All callers changed to call with ANSI == 1, except from
3412 `check_method_stub', which uses old-style syntax.
3414 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3415 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3417 * values.c (check_stub_method): New function.
3419 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3421 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3422 * valprint (type_print_base): Ditto.
3424 * symtab.c (gdb_mangle_typename): New function.
3426 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3428 * breakpoint.c (catch_command): New function. Provides a
3429 mechanism to set breakpoints based on catch clauses.
3430 (disable_catch): Similar, but disables breakpoints on catch
3432 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3434 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3436 * blockframe.c (blockvector_for_pc): New function.
3437 * blockframe.c (block_for_pc): Changed to call
3438 `blockvector_for_pc' and get the block itself.
3440 * stack.c (catch_info): New function. Prints info about
3441 exceptions which can be caught in the current frame.
3442 * stack.c (print_frame_label_vars): New function. Similar to
3443 `print_frame_local_vars'.
3444 * stack.c (print_block_frame_labels): Prints out labels that are
3445 defined in this frame. These labels are exceptions that can be
3448 * dbxread.c: Updated to handle N_CATCH symtab types.
3450 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3452 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3453 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3454 when printing the type.
3456 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3458 * valprint.c (val_print): Use `baseclass_addr' to access the
3459 baseclasses pointed to via the derived class object at VALADDR.
3461 * values.c (baseclass_addr): New function. Casts derived pointers
3462 to baseclass pointers taking virtual baseclasses and multiple
3463 inheritance into account.
3465 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3469 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3471 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3472 exp_valid_block field correctly.
3474 * infrun.c (wait_for_inferior): When checking "don't even think
3475 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3476 also check step_resume_breakpoint.
3477 Insert breakpoints and continue (not step) if
3478 step_resume_break_address != NULL, even if another_trap.
3479 If trap_expected and we enter sigtramp, then set up a
3481 If trap_expected is set when we hit the step_resume_break,
3483 When calling resume and trap_expected says tell resume to step
3484 (2 places), also check step_resume_break_address.
3486 * infrun.c (wait_for_inferior): Don't set
3487 prev_{pc,sp,func_{start,name}} before calling wait ().
3488 Do set them after exiting loop.

3492 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3494 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3495 Restore old code which distinguishes between trap_expected and
3496 running_in_shell, just make the latter take any non-TRAP signal,
3499 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3501 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3502 xconfig/3b1 (CC,PINSN_CC): Define.
3504 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

3526 char. Add macro VALUE_OPTIMIZED_OUT.
3528 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3529 instead of stuffing things in buffers (oappend, etc).
3531 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3532 execute_command, exit both loops.
3534 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3536 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3539 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3541 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3543 * valops.c (value_struct_elt), values.c (value_static_field):
3544 Change error messages to remove references to `info methods'.

3561 findvar.c (get_saved_register): New function.
3562 findvar.c: Rewrite code which called find_saved_register to
3563 call get_saved_register instead.
3565 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3567 * valprint.c (val_print): Change error message printed when
3568 the type has TYPE_FLAG_STUB set.

3576 Fri Apr 20 11:31:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3578 * findvar.c (write_register): Add PREPARE_TO_STORE.
3579 {sun3,sparc,symmetry}-xdep.c (PREPARE_TO_STORE): Add.
3580 infptrace.c, {mips,pyr,symmetry,sun3,arm,hp300hpux}-xdep.c
3581 (store_inferior_registers): Don't call read_register_bytes.
3582 symmetry-xdep.c (store_inferior_registers):
3583 #if 0 out code to fetch registers.
3585 * values.c (value_as_long): Call COERCE_ARRAY.
3587 * tm-sun3.h: Include tm-68k.h not m-68k.h
3589 * sparc-tdep.c (single_step): Set next_pc, npc4 within

3596 * coffread.c (read_one_sym): If there is more than one
3597 aux entry, don't give an error message, just ignore the
