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

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

259 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
261 * m68k-stub.c: Remote stub for 680x0's, created from

264 Remove RCS log stuff now that we use CVS and it blows our diffs.

282 been read in, particularly for VxWorks.
284 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
285 to the main file, as well as to include files. Also, put global
286 functions into the global psymtab, to make "i fun" work.
287 (end_psymtab): Free named symtabs and psymtabs for a file, once a
288 new psymtab for it has been read.
289 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
290 a file, once a new symtab has been read for it.
291 * mipsread.c: FIXME. We need to do the same for MIPS, but it
292 looks harder to determine the top-level block before it's been
293 queued to the psymtab list.
295 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
296 If we have wiped out any old symbol tables, clean up at end of
298 (symbol_file_command): Don't reference symfile_fns if it's zero.
300 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
301 defines for the blocks of a blockvector that contain global and
302 file-static symbols and the first of the smaller scope contours.
303 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
304 decode_line_1, make_symbol_completion_list): Use the above.

322 Remove RCS log stuff now that we use CVS and it blows our diffs.
324 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
326 * symmisc.c (free_named_symtab): Make it work, in its current
327 kludgy fashion. Change result to indicate if we blew away bkpts.
328 * dbxread.c (end_symtab): Accumulate result from
329 free_named_symtab and print warning if we blew user's state.
330 * symfile.h: free_named_symtab now returns an int.
332 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
334 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
335 is the first symbol read, even if not mainline.
336 (dbx_psymtab_to_symtab): symfile might be zero, cope.
337 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
338 (set_section_command): New command ("section xxx yyy" -- should
339 be renamed to "set section xxx yyy" FIXME) which sets the
340 base address of a section of the exec file, overriding the
341 virtual address that BFD reports.
343 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
345 * exec.c: Add add_syms_addr_command to exec_ops, so you can
346 load symbols at any address while examining an exec file.
348 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
350 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
351 for printing the float info is host-dependent, not
352 target-dependent. FIXME.
353 * i386-pinsn.c: Move #includes to top, remove useless ones.
354 * i386-tdep.c: Don't bother including <.../reg.h> since we
355 don't use it (and it doesn't exist on host systems).
357 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
358 Convert negative numbers properly.
359 (ieee_test): Make numbers really random; fix format arg.
361 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
362 * core.c (core_detach): Unpush core_ops, which might not be on
363 top. We used to just pop the top, which broke things. Don't
364 need dont_repeat() any more.
365 (core_file_command): Psst! Don't repeat it.
366 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
367 * expprint.c (print_subexp): Avoid switch fallthru on
368 BINOP_ASSIGN_MODIFY, so we can print += and such.
370 * inflow.c (kill_command): After killing inferior, print our
371 current frame in the core file, if we have one.
372 (generic_mourn_inferior): When inferior dies, either select
373 the current frame (in the new target, e.g. core file), or
374 set both the current and selected frames to NULL.
376 Changes from Peter Schauer.
378 * infptrace.c: Avoid <sys/ptrace.h> on USG.
380 * Make all file names fit in 14 characters (sigh and damn!):
381 mv hp300hpux-xdep.c hp300ux-xdep.c
382 mv symmetry-xdep.c symm-xdep.c
383 mv symmetry-tdep.c symm-tdep.c
384 mv convex-opcode.h convx-opcode.h
385 mv tm-vxworks960.h tm-vx960.h
386 mv tm-vxworks68.h tm-vx68.h
387 mv Makefile.srcdir Makefile.sdir
388 mv gdb-int.texinfo gdbint.texinfo
389 mv remote-sa.m68k.shar rem-m68k.shar
390 mv remote-multi.shar rem-multi.shar
391 * Makefile.dist, README, config.gdb, convex-pinsn.c,
392 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
393 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
396 * command.c (user_info_1, user_info): New command for listing
397 the user-defined commands.
399 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
401 * dbxread.c (really_free_pendings): Clear file_symbols
402 and global_symbols after freeing them; otherwise, running
403 this function twice (if it appears twice on the cleanup
404 chain), we try to free things twice.
406 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
407 based on text_addr (the address of text in core), not on addr (the
408 offset between text in the .o file and in core). This change
409 is from Peter Schauer.
411 * main.c: Define ALL_CLEANUPS as a cast of zero.
412 (return_to_top_level): Use it.
413 (main): Do all cleanups after each command run as part
414 of the gdb startup sequence. Also do all cleanups before
415 entering the command loop, and every time we exit the command
416 loop and reenter. Before, the cleanups from the startup sequence
417 were being left undone until the first error!
418 (command_loop): Rename do_nothing cleanup to command_loop_marker
419 so we can see it easily when examining the cleanup chain.
420 (init_signals): Add another do_nothing for signal handling.
421 (quit_command): Only try to kill target if it has execution.
422 Problems in the target stack got us into a state where
423 inferior_pid was nonzero but none of the targets had execution.
424 In this state you couldn't exit gdb.
426 * dbxread.c: Two changes from Peter Schauer.
427 (echo_command): Fflush output after an echo command.
428 (show_history): Pass all args to cmd_show_list.
430 * utils.c (init_malloc): Call mtrace to turn on tracing
431 if the environment variable MALLOC_TRACE is set to a file name.
432 * mtrace.c: Add source file which provides a log of every malloc,
433 free, and realloc to a trace file.
434 * mtrace.awk: Add source file which analyzes the trace file.
435 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
436 (VERSION): Roll to 3.94.3.
438 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
439 (check_duplicates): Don't bother with watchpoints.
440 (set_raw_breakpoint): Comment about danger of this routine.
441 (watch_command): Parse and eval all args before calling
444 * solib.c (find_solib): Avoid error in referencing memory to
445 see if any more shared libraries have been added. This is
446 particularly useful if the target has terminated. Bug reported
450 in bringing up 3.94.2 on the Sun-3.
452 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
453 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
454 expression (in scope) before reenabling watchpoint.
455 * signame.c (init_sigs): Add missing declaration of i, fix
456 sys_siglist declaration.
457 * source.c (list_command): Fixed range computation to use
459 * stack.c (backtrace_command): Do not allow command if target has
460 no stack, print informative error message.
461 * target.c (target_command): Do not write into command line
462 because this fails if the target command is used in a user defined
463 command. [This change was enhanced by gnu to support any-
464 unique-prefix matching on target names.]
465 * valops.c (value_struct_elt): Avoid infinite loop on an
466 erroneous attempt to print the member of function (try p main.p).
468 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
470 * expread.y (name_no_typename): Avoid reduce/reduce errors
471 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
472 Since the GDB parser really doesn't use name_no_typename in a
473 name-only context, the parser can't tell the diff between
474 names and numbers here. Avoid allowing a name_no_typename
475 to be a NAME_OR_*INT to resolve the conflict.
477 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
481 * valprint.c (val_print_fields): bitfield printing didn't handle
482 byte order. Indirect through a few more fns to cope.
484 * values.c (modify_field): also cope with byte order.
486 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
488 Cleanup for release 3.94.2:
490 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
491 include files. Roll version to 3.94.2.
493 * coffread.c (init_stringtab): Read length into unsigned char
494 array before swapping; don't assume 32-bit longs.
496 * target.c (target_info): Don't bother with get_sym_file, just use
497 the symfile global variable.
498 * symtab.h, symfile.c (get_sym_file): Delete it.
500 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
501 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
502 (read_type): Replace one more error() with complain().
504 * mipsread.c (parse_partial_symbols): Replace printf with complain.
506 * i960-tdep.c: Fix copyright attribution.
508 * config.gdb: Quote all backquotes in doublequotes. You can
509 quote me on that. BSD 4.4 shell found this one.
511 * infptrace.c (throughout): The third argument to ptrace is an
514 * infrun.c (wait_for_inferior): When program has terminated, we
515 have to call target_terminal_ours before we pop that target off
516 the stack (e.g. before a call to target_kill or
517 target_mourn_inferior). This fixes problem where a program
518 terminates, then GDB stops for (tty output) and you have to type
519 "fg" to the shell to resume it. FIXME: This code for what to
520 do after termination really should be in normal_stop instead.
522 * gdbcore.h (read_memory_check): Change declaration; it changed
525 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
526 4.4 prereleases, this avoids a bug in their sgtty compatability
528 * remote.c: Use terminal.h rather than hand-rolling the same.
530 * signame.c, signame.h (psignal): Arg is unsigned, not int.
531 * utils.c (strsave, strstr): Fix arg types.
532 * valprint.c (val_print): lint
534 MIPS symbol table support from Per Bothner:
536 * symfile.c (symtab_fns): Remove initializer table that needs to
537 be hacked for each new symbol file format supported.
538 (add_symtab_fns): New function, chains symbol table
539 handlers into the global list.
540 (symfile_init): Search this list.
541 * symfile.h: Add next pointer, declare add_symtab_fns.
542 * coffread.c (_initialize_coffread): Call add_symtab_fns.
543 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
545 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
546 symbol *). Thus, we no longer need the hack to trash
547 pst->filename. Good, since that hack confused code in symfile.c!
549 (reorder_symtabs, destroy_all_symtabs): Removed static
550 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
551 Instead, the latter now uses a temporary array (stack-allocated
552 from an obstack, and then freed).
554 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
555 haven't been set in the outermost stBlock of a procedure. This was
556 a problem with f77 binaries on Ultrix 4.?.
558 (new_symtab, new_symbol, new_type): Continue changing code to use
559 obstacks more and otherwise conform to dbxread internal style.
560 Made the free_code of symtabs be free_linetable (as in dbxread)
561 instead of free_contents. This implies memory leaks when reading
562 a new symbol table, until the conversion is finished. Did change
563 (struct symbol) and (struct type) to be allocated on the
564 symbol_obstack. Blocks and blockvectors are among the things
567 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
568 tested much, but it solved one problem (reported by Meissner), and
569 cleans up some other things. The problem happened when an
570 included file contains actual code (functions) and not just
571 definitions. The mips coff is a little inconvenient there, since
572 it may cause a procedure to be mapped to the wrong psymtab.
574 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
575 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
576 this will need work for the new core paradigm.
578 Opcode patches from the net:
580 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
581 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
582 missing altogether - they are added here. From Bruce Bauman.
583 * mips-opcode.h: The low mask for C0 instructions was too small.
584 From Garrett Lau. I modified the fix to check the entire 32-bit
587 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
590 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
592 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
594 * dbxread.c (read_type): Pointer subtraction (value_sub in
595 valarith.c) sometimes failed because the types of the
596 pointers being subtracted were not identical.
597 These differed because dbxread.c was allocating pointer types
598 using dbx_alloc_type+smash_to_pointer_type instead of
599 lookup_pointer_type. I failed to find a justification for the
600 former, so I changed it to use the latter. Similarly, I
601 replaced smash_to_function_type by lookup_function_type,
602 and smash_to_reference_type by lookup_reference_type.
604 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
605 _initialize_mipsread): corresponding changes.
607 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
609 * source.c (mod_path): Do tilde_expand on each component of the path,
610 rather than on the (list of) paths as a whole.
611 (print_source_lines): Set first_line_listed in addition to
612 current_source_symtab and current_source_line. If the source was
613 not findable, after a "dir" command to fix the problem,
614 a "list" would get the wrong lines.
616 While I was there... (gnu):
618 * dbxread.c (read_type): Change error to complaint.
620 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
622 First attempt at detailed understanding of symbol table memory alloc.
624 * dbxread.c (dbx_symfile_read): Free our string table if we
625 aren't the mainline. Free the "info" struct since we're done with
627 (init_psymbol_list): Free any previously allocated psymbol lists.
628 (): FIXME: Should realloc-down the psymbol lists when done reading
629 the main symbol file?
631 * symmisc.c (free_symtab): Free fullname field too.
633 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
634 (REGISTER_ADDR): Make result type unsigned int.
636 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
637 define REGEX must also define REGEX1 (its dependency).
639 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
641 * tconfig/i960: No longer works, points you at vxworks960 or
644 * xgdb.c, XGDB-README: Remove file. Users can get the much
646 * Makefile.dist: Remove all trace of xgdb.
648 * breakpoint.c (breakpoint_1): Pass demangle arg to
649 print_address_symbolic.
650 (clear_breakpoints): Remove unused function.
651 (breakpoint_re_set_one): Guts of breakpoint_re_set.
652 (breakpoint_re_set): Use catch_errors to do them all anyway.
654 * gdb-int.texinfo (Host versus Target): Add section on what is
655 a "host" feature versus what is a "target" feature.
657 * infcmd.c (path_command, path_info): Handle the PATH variable
658 (object search path) as conveniently as the source search path.
659 * environ.c (set_in_environ): Set some vars in GDB's environment,
660 in addition to the child's. PATH, G960BASE, G960BIN for starters.
661 * source.c (mod_path): New function, from guts of
662 directory_command, modifies a path. Used by path_command.
663 (directory_command): Call it.
664 * defs.h (strsave): Declare.
666 * utils.c (sevenbit_strings): Add new printing option.
668 (strsave): Provide this handy helper routine.
669 (set_width_command): Rename set_screen_width_command.
670 (_initialize_utils): "set screen-width" => "set width";
671 "set screen-height" => "set height"; add sevenbit-strings.
673 * infcmd.c (do_registers_info): Print floating point registers
674 in raw hex as well as float format, regardless of whether it is
675 a "virtual" convertible register.
676 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
677 regs as a double, just in case it's being used that way.
678 * values.c (unpack_long): Comment on array/function coercion.
679 (unpack_double): Argument is in target byte order now. For
680 integer arguments, just call unpack_long and float the result.
681 * m68k-tdep.c: include defs.h for "const" handling.
682 * remote-nindy.c: Use ieee-float stuff.
683 (nindy_fetch_registers): Unpack double regs to host double, then
685 (nindy_store_registers): Pack extendeds to host double, flip
686 around by misusing unpack_double, send as target double.
688 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
689 zero, as when stopped at the first instruction of a process.
691 * blockframe.c: Fix filename in comment (param.h => tm.h).
692 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
693 * tm-68k.h: Fix typos.
695 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
697 Changes from a bringup on the DEC Vax under Ultrix 4.0.
699 * coredep.c (fetch_core_registers): Pass end-address of register
700 section to register_addr as expected. Don't call supply_register
701 if we'd just pass it garbage.
703 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
705 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
707 * target.c (push_target, target_info): Cast enums to int for < or
710 * stack.c (print_frame_info): Identify source file & line
711 even if we can't print it.
713 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
715 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
717 Clean up IEEE floating point support.
719 * ieee-float.h: New file.

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

804 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
805 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
806 declarations of errno.
808 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
810 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
811 <rpc/rpc.h> and <rpc/types.h>.
813 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
815 * i960-tdep.c (examine_prologue): Add new argument limit,
816 which stops the scan at the end of the prologue, or at the PC.
817 This fixes a problem where it walks down into the code for the
818 user's statements if that code looks like function prologues.
819 Mark Fox and I have been bouncing this code back and forth, making
820 small changes to it. Callers changed to match.
822 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
824 Cleanup for gdb-3.94 release final:
826 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
827 the .c files from vx-share and nindy-share, from the various
828 macros, since they are not found via ALLDEPFILES.
829 (SFILES): Add tm-i960.h.
830 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
831 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
833 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
834 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
836 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
838 * am29k-tdep.c: Add contribution line.
839 (examine_prologue): Cache information about function prologues in
840 the misc-function-vector to avoid lots of references over the
841 serial line while examining instructions.
843 * core.c (core_close): New function made from cleanup_core.
845 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
846 remote-vx.c, remote.c, target.c, target.h,
847 Update target_ops vector to add attach, close, and load entries.
848 Use add_syms_addr_command, not add_file_addr_command, for
849 add_file. Break out close routine from existing code.
851 * dbxread.c (really_free_pendings): Don't free pending_blocks;
852 they are in an obstack.
853 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
855 (define_symbol): Add symbol type parameter; change callers;
856 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
857 it to influence the symbol class on the i960.
858 (define_symbol): Swap LOC_CONST's into target byte order.
860 * exec.c (exec_close): New function.
861 (exec_file_command): Call it.
863 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
864 Fix byte order of frame pointer.
865 (read_var_value): Result of 0 if var's value can't be found,
866 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
867 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
868 (locate_var_value): Use read_var_value and use its lazy address
869 as the location of the var's value. Lint.
871 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
874 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
875 obsolete Intel versions in favor of vxgdb versions.
876 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
877 code dealing with byte order of values, which Intel did in host byte
878 order rather than gdb-4's target byte order.
879 (i960_frame_chain_valid): Move to nindy-tdep.c.
880 (examine_prologue, skip_prologue, frame_find_saved_regs,
881 frame_args_address, leafproc_return, saved_pc_after_call,
882 pop_frame): Add vxgdb versions from Mark Fox.
883 (examine_prologue, frame_struct_result_address): Add code
884 to deal with the saved value of G13 (struct return address
886 (frame_args_address): Modify Mark's version to prefer the
887 saved value over the current value in the topmost frame.
888 Cache result in the frame info to avoid performance hair in
890 (print_fault): Add gdb960 code for printing faults.
891 (_initialize_i960): Actually call check_host.
893 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
894 add stub routines. FIXME, these currently just return zero!
896 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
897 (attach_command): Call target_attach, not target_open, now.
899 * infrun.c (normal_stop): Make global, not static, for vx_attach.
900 (child_attach): Rename from child_open.
901 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
902 don't confuse it with a zero step_resume_break_address.
904 * inftarg.c (child_detach): Eliminate inferior_pid test.
905 (child_files_info): Clean up message a bit.
906 (child_ops): Use child_attach, not child_open, to attach.
908 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
909 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
910 findvar.c to here, since it depends on the contents of the
911 shadow_contents of breakpoints, but keep if #if 0 since it is
914 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
917 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
918 (ptype_command, display_command): Eliminate have_inferior_p and
919 have_core_file_p in favor of target_has_stack or
920 target_has_execution.
921 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
922 code for actually finding the values of arguments, though we still
923 keep track of the maximum stack offset for use in printing unnamed
924 arguments. Handle missing FRAME_ARGS_ADDRESS.
926 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
927 (struct nindy_regs): Define registers passed to/from nindy.
928 (nindy_fetch_registers, nindy_store-registers): Translate between
929 nindy and GDB formats for the registers.
930 (dcache_init): Statically allocate the cache, since it was being
931 allocated by a malloc that was never freed anyway.
932 (nindy_create_inferior): Error, not core dump, if no exec file.
933 (nindy_before_main_loop): Use target_load, not target_add_file.
935 * remote-vx.c (net_load): Specify large timeout for load
936 requests. Allow user to break out with INTERRUPT.
937 (net_break): Remove useless code, clean up. Change callers.
938 (parse-args, skip_white_space, find_white_space): Clean up arg
939 parsing to cope with quoted strings.
940 (net_wait, net_quit): Never call error, just return status.
941 (vx_read_register, vx_write_register): Cleanup status checking.
942 #ifdef the code based on which CPU we are using (960 or 68k),
943 FIXME, this should be completely general but it isn't yet.
944 (vx_xfer_memory, vx_resume): Cleanup status checking.
945 (vx_run_files_info): Improve message.
946 (vx_load_command): Renamed from vx_add_file_command. Allow load
948 (net_ptrace): Remove unused routine.
949 (vx_wait): Adopt code from vxgdb960 to cope with broken
950 connections to target machine and prompt to disconnect. Remove
951 debug printouts. Map some EVENT_'s to SIGnals.
952 (add_symbol_stub, vx_open): Print names of object files we found,
953 and "ok" if we read their symbols OK. Clarify output in general.
954 (vx_attach, vx_detach, vx_kill): Add these commands.
955 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
956 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
957 "info files" output, and create_inferior, since we already have
960 * stack.c (frame_info): Replace Frame_unknown with 0.
961 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
962 (return_command): Pop until the PC matches as well as the FP,
963 so it works even if the FP is shared with another function,
964 as in "frameless" or "leaf" procedures.
966 * symfile.c (load_command): renamed from add_file_target_command.
967 (add_syms_addr_command): renamed from add_file_addr_command.
968 (add_syms_command): Stub to call target_add_syms.
969 (_initialize_symfile): Change command names and descriptions,
970 add-file => add-syms, and load from alias to its own command.
972 * target.c (kill_or_be_killed, maybe_kill_then_attach,
973 maybe_kill_then_create_inferior): Default for attempts to start
974 a process, if one is already running, is to ask about killing
976 (upstack_create_inferior): #if-0 it, strata obsolete it.
977 (push_target, unpush_target, pop_target): to_close() a target
978 before unstacking it.
979 (target_info): Renamed from target_files_info.
980 (_initialize_targets): Rename "i files" as "i target", accessible
983 * target.h: Improve comments about the target_ vectored routines.
985 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
986 Convert commenting style to standard GNU style.
987 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
988 (SKIP_PROLOGUE): No longer a no-op.
989 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
990 (*_REGNUM): Sort register numbers.
991 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
992 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
993 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
994 are now 10 byte extendeds, not 8 byte doubles.
995 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
996 for nindy versus vxworks targets. FIXME, this should possibly go
997 in the target vector.
998 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
999 frame_saved_regs and arg pointer with each frame.
1000 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1001 (FRAME_ARGS_ADDRESS): Use cached result.
1002 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1003 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1004 (PRINT_RAMDON_SIGNAL): Call print_fault.
1005 (POP_FRAME): Now works.
1007 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1008 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1009 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1010 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1013 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1014 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1016 * valarith.c (value_subscripted_rvalue): Avoid handling
1017 floats and doubles specially; it gave alignment errors. Lint.
1019 * valops.c (value_of_variable, value_of_this): Error if unknown
1022 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1023 to avoid alignment problems.
1024 (value_print): Handle unknown value address.
1025 (cplus_val_print): Two args are ignored; remove them. Change caller.
1026 (val_print): Use unpack_long rather than pointer-deref.
1029 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1030 to avoid alignment problems.
1031 (value_being_returned): Error if return value unknown.
1032 (set_return_value): Add bogosity warning, FIXME. *
1034 * TODO: A woman's work is never done.
1036 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1037 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1038 Add ieee-float.o to OBS.
1039 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1040 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1041 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1043 Changes to generalize the VxWorks RPC protocol slightly, to handle
1044 i960 as well as 68000.
1046 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1047 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1048 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1049 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1050 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1051 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1052 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1053 so they will move in target byte order rather than network
1054 byte order (happens to be the same).
1056 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1058 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1060 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1063 Add contribution lines to various files, showing where they
1066 * breakpoint.c (break_insn, check_break_insn_size,
1067 read_memory_nobpt): Remove to mem-break.c.
1069 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1072 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1073 entry has bad register number. This change is not
1074 tested in this release, FIXME.
1076 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1079 * value.h: Force value's contents field to be aligned to hold
1080 at least a double or a long long (if supported). This avoids
1081 doing bcopy's in and out of the contents field.
1083 (step_1): Avoid coredump under obscure circumstances when we
1086 * symtab.h (misc_info): Add field to misc function vector for
1087 any kind of cached information the target code desires. AMD
1088 29000 uses this to avoid repeating examine_function_prologue's.
1090 * coffread.c: Lint. Remove static symfile, read_section_header.
1091 core.c (have_core_file_p): Lint: remove.
1092 expprint.c (print_subexp): Lint.
1093 infptrace.c, valops.c, valprint.c: lint.
1095 Roll in changes from vxgdb-5.0.1:
1097 * symtab.h: Comment byte order of each address class. Add
1098 LOC_LOCAL_ARG for frame-relative args (960).
1099 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1100 symtab.c, symmisc.c: ditto.
1102 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1104 * remote.c (remote_resume): Error if resume with a signal.
1106 * symfile.c (prim_record_misc_function): Clear misc_info.
1107 (fill_in_vptr_fieldno): Check stub type of arg.
1109 * valops.c (value_cast): Avoid looking up names of types whose
1110 name we don't know, to prevent coredump. Sun CC produces typedef
1111 rtx and the name of *rtx is zero...
1113 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1115 Roll in changes from final AMD 29000 port (Tiemann).
1117 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1118 for ../include/a.out.encap.h. This might not work now that BFD
1119 is separately compiled. Instead, BFD support for encap will have
1120 to translate machine type 29k into the right COFF_MAGIC.
1122 * infcmd.c: Remove references to inferior_pid that aren't used
1123 in actual ptrace calls; use target_has_execution, etc.
1124 (have_inferior_p): Remove function.
1125 (program_info): Print target info rather than "process number";
1126 avoid gratuitous messages unless from_tty.
1127 (run_stack_dummy, finish_command): Set proceed_to_finish.
1128 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1129 main.c: Lint. Lose have_inferior_p().
1130 inferior.h (have_inferior_p): Remove, lint.
1131 (proceed_to_finish): Add flag to ask that all regs be saved
1132 by normal_stop, for the few commands that need it, speeding up
1133 serial I/O. Add comments to stop_registers.
1135 * remote-eb.c: Remove newline from breakpoint message we grep
1136 for. Never time out when running the user program.
1140 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1142 Roll in changes from vxgdb-5.0.1:
1144 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1145 symbol in its raw form, we are processing an unlinked ".o" file.
1146 See if the target environment has assigned it an address, using
1147 target_lookup_symbol (VxWorks does), and enter it into the symtab
1150 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1151 68k versions for a simpler version that assumes zero FP at bottom.
1152 Fixes bug of truncated stack reports.
1154 * target.h (target_lookup_symbol): Define this routine's args
1155 and result, finally.
1157 * target.c (nosymbol): Default routine for target_lookup_symbol.
1158 (target_default): Default lookup_symbol and call_function too.
1159 (files_info): Only print has_all_memory warning if a non-dummy
1162 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1163 vx_convert_from_virtual): If target does not have floating point,
1164 zero register "values", and avoid doing cross-net conversions.
1165 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1166 (vx_open): Rearrange code that attaches to target and reads
1167 symbols for all loaded modules, to work if some of the modules
1168 are not accessible. Add symbol_stub() and add_symbol_stub()
1169 as callbacks from catch_errors(). Allow connect attempt to be
1170 interrupted painlessly with ^C (FIXME, there are still some bugs
1171 if the interrupt happens during symbol reading.). Print
1172 final message with puts_filtered, since symbol messages are
1177 * main.c (catch_errors): Only print errstring if non-null.
1178 (command_loop): Avoid an ioctl per command to test ISATTY.
1180 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1181 (vx_xfer_memory): Return correct result!
1182 (vx_files_info): Indicate whether target has float or not.
1183 (vx_lookup_symbol): Complain, not error, if target gone.
1184 (vx_open): Print "Connected" msg before disabling immediate-quit.
1185 [FIXME: lookup_symbol and vx_open changes need testing.]
1187 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1188 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1189 contributor lines and update copyrights to 1991.
1191 Changes from an attempted H-PUX host port:
1193 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1194 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1195 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1196 * remote-vx.c: include <sys/time.h> for HPUX.
1197 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1198 "core_file_command" routine to BFD regime. May not work yet.
1200 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1202 * xgdb.c: Replace X10 version with some VJ version.
1203 (FIXME: Its copyright assignment is not on record.)
1204 * xgdb.c: Update include files to X11R4 (Xaw crud).
1205 (xgdb_display_source, create_text_widget): fix call to
1206 get_filename_and_charpos. Rewack source window stuff for X11R4
1207 (gleaned from include files, and "nm's" of binary libraries, since
1208 I had no doc available).
1209 (append_selection, append_selection_word): Disable with FIXME
1210 since R4 changed interface here.
1211 (create_buttons): Add back the old set of buttons.
1212 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1214 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1215 Roll VERSION to 3.94 (not yet final though).
1217 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1219 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1220 obstack_int_grow, obstack_int_grow_fast): Eliminate
1221 cast on left of assignment, which gives MIPS cc fits and is
1224 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1225 F_ALIAS. Use printf, not fprintf, when not passing a file
1227 (compare_opcodes): Check that identical instructions have
1228 identical opcodes, complain otherwise.
1230 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1231 was reported by Roland McGrath.
1232 (unimp): Only match if exactly zero instruction. (Roland)
1233 (branches and traps): Generate all variations of these
1234 instructions with macros, based on a single call that defines
1235 each condition name and its binary representation.
1236 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1238 * valprint.c (val_print_fields): Take, and use, format parameter.
1239 This means that "p/x struct" again prints the elements in the
1240 desired format. Changed callers.
1242 * stack.c (frame_info): Use filtered output, and indicate wrap
1243 points. Remove kludgy formatting designed to avoid line wrap.
1245 * utils.c (wrap_here): If the line is already full (because
1246 we had printed a long indent or long wrapped string), do an
1247 immediate newline-and-indent.
1249 * m68k-pinsn.c (print_insn_arg): Bugfix from
1251 instruction is incorrectly disassembled as bkpt #8.
1253 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1255 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1256 and then will dump core (sometimes). I traced it back to an
1257 uninitialized symfile_name in psymtab_to_symtab.
1258 (const_vol_complaint): Add quotes to message.
1259 (define_symbol): Only believe line number if gcc_compiled.
1260 Avoid allocating symbol if we will not return it.
1262 Add target strata support so that newly established targets go
1263 into their right place in the target stack (e.g. a new exec file
1264 doesn't wipe out the ability to access the running process).
1266 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1267 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1268 and initialize it properly in all the targets.
1270 * target.h: Document strata. Change return type of push_target.
1272 * target.c (nomemory): new function for dummy memory access.
1273 (tcomplain): Rename complain, now also used in symfile.c.
1274 (push_target): Push targets within strata. New return value shows
1275 whether new target is on top of stack or not. Always keep dummy
1277 (target_files_info): Ignore dummy target.
1279 * core.c (core_open): Warn user, and skip accessing file, if the
1280 core target is not the topmost target in the stack.
1281 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1284 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1285 target_ops, it doesn't belong there since we have no regs there.
1286 Change name of target from machine => memory to clarify.
1288 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1290 * Freeze version 3.93 for release.
1292 * Makefile.dist: Handle vx-share and nindy-share subdirs
1293 properly when building gdb.tar.Z.
1295 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1296 printed in various places, so I could change just one copy.
1298 * dbxread.c, coffread.c: Change references to bfd->iostream
1299 to cast to FILE *, now that BFD avoids needing types defined
1300 in other header files.
1302 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1304 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1305 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1306 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1307 (actually gcc -Wall).
1309 * dbxread.c: Remove first_global_sym, last_global_sym, since
1310 they are never referenced.
1312 * defs.h (baud_rate): Declare.
1313 main.c: Define it, and add the -b option to set it.
1315 * gdb-int.texinfo: Add text on how to define a new host or target
1316 architecture, prompted by Per Bothner's questions about MIPS
1319 * gdb.texinfo: Document "complaints". Change doc of -q since
1320 gdb no longer prints the copyright and blurb if you specify a file
1321 name to be debugged (just like Emacs). Add doc for Nindy-specific
1322 command line flags for specifying target serial port and such.
1323 Update copyright to 1991.
1325 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1326 has taken over for us the job of ripping up executable files. The
1327 crud caused Per Bothner's port to not compile.
1329 * infrun.c (normal_stop): Avoid printing "Program exited
1330 normally" if we are in batch mode. This allows a GDB which
1331 executes a program on a target system, to behave like a Unix
1332 command (input from stdin, output to stdout, no extraneous
1335 * main.c (main): Allow additional machine-dependent command line
1336 options to be specified with the ADDITIONAL_OPTIONS,
1337 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1338 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1339 processing to occur just before the main loop with
1340 BEFORE_MAIN_LOOP_HOOK.
1341 (main): If a "core file" argument is specified, and it is not a
1342 core file, try it as a process ID to attach.
1343 (symbol_completion_function): Attempt to cope with
1344 "show screen-" TAB, not very successfully. This needs more work,
1346 (batch_file): New function, returns whether we are reading
1347 commands from an interactive tty on stdin, or from somewhere else.
1348 Called by normal_stop since it doesn't get from_tty passed down
1349 to it like many commands do.
1351 * remote-nindy.c: Handle command line options for nindy
1353 (nindy_before_main_loop): Prompt user for tty name if they
1354 don't specify it before getting to the interactive command loop.
1356 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1357 and -r command line options. Also add hook before main loop
1358 to make it easy to specify a tty.
1360 * TODO: More things to do, one done.
1362 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1364 * dbxread.c: Make complaint() calls pass pointer, not struct.
1365 Add complaints about badly formatted C++ type information
1366 (const/volatile indicator, and parse errors resulting in
1367 error_type). Fix C++ virtual member fn comment.
1368 (read_struct_type): Avoid bumping pointer if we got a parse
1369 error; this prevents our walking beyond the end of a string.
1370 Terminate loop on null char as well as semicolon.
1371 (process_one_symbol): Fix the LBRAC fix so that it uses the
1372 last previous SLINE, FUN, or SO record's PC address. C++ debug
1373 symbols did not have SLINE records in a useful order compared
1374 to the LBRAC records.
1375 (define_symbol): Handle "catch" records.
1377 * symtab.c (check_stub_type): Added new complain
1378 `stub_noname_complain' and added a consistency check to
1379 keep the debugger from crashing when finishing from an
1380 exception frame. A real fix will be needed later.
1382 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1384 * infcmd.c (attach_command): Make global.
1386 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1387 but make them easy to comment out. Perhaps later they should
1388 be enabled by what CPU you configure for? FIXME.
1389 (VERSION): Roll to 3.93.
1390 (pinsn.o): Remove rule for obsolete file.
1391 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1393 Run down a problem that manifested by printing the wrong function
1394 name in stack traces of read_ofile_symtab. Turned out that the
1395 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1396 the LBRAC symbol with an address in the *data* segment, which
1397 blew our binary search through the blocks.
1399 * dbxread.c: Use the complain() facility consistently to bitch
1400 about problems in the symbol file we are reading.
1401 (finish_block): Add code to check the nesting of the blocks;
1402 complain and Procrust them to fit if wrong.
1403 (make_blockvector): Check the order of the blocks, complain
1404 [but don't cope] if wrong.
1405 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1406 symbols to be sure their PC value is greater than the last SLINE
1407 (line number) symbol we've seen, complaining and adopting the
1408 SLINE PC value if wrong.
1410 * symfile.h (struct complaint, complaint_root, complain,
1411 clear_complaints): Add.
1412 * symfile.c (complain, complaint_root, clear_complaints): Add
1413 facility to deal with non-fatal complaints and to regularize their
1415 (symbol_file_add): Clear complaint counters to allow new complaints.
1416 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1418 * dbxread.c (dbx_symfile_read): Remember the address and size
1419 of the string table for the main symbol file, so we won't read it
1421 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1422 to avoid reading the string table yet again. Lint.
1423 (throughout): Improve filtered output, including word wrap.
1424 (read_range_type): Improve Bothner's fix to handle other types too.
1426 * utils.c: Improve line wrap implementation. Handle unlimited
1427 width by making chars_per_line unsigned.
1428 (puts_filtered): New, easy, function.
1430 * defs.h (puts_filtered): add.
1432 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1433 call the identical sort_symtab_syms() in symfile.c instead.
1435 * expread.y: Suggest the `file' command rather than `symbol-file'.
1437 * command.h (enum var_types): Add zinteger for seroable
1439 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1440 nested if's into a switch.
1442 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1443 we did not stop because of a breakpoint (it must have been for
1444 some other reason, like a "stepi"), so don't print anything.
1446 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1447 doesn't include <sys/types.h>, old SunOS's require it for
1452 A test port of gdb-3.92.6 to the Sony NEWS.
1455 Don't normally link in remote- or vx stuff.
1456 Some of it doesn't compile, and it wastes space for 99% of the users.
1457 Remove reference to no-longer-used HAVE_VPRINTF.
1458 Fixed BFD_DEP typo to BFD_DIR.
1460 Fix cast in arg to bfd_h_getlong.
1461 Make char *prefix be const.
1462 Fix how certain range types are mapped into builtin unsigned int types.
1464 Remove 2 #includes. They cause errors (on Sony, at least),
1465 and aren't needed (they wern't in earlier versions).
1467 print_address_symbolic should never demangle labels
1468 (since it prints *assembler-level* labels).
1470 [This was superseded by the change to printcmd below.]
1473 Add some "volatile" return types to avoid warnings.
1474 If MISSING_VPRINTF add vprintf function and not just macro
1475 (since vprintf is used in printcmd.c).
1477 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1478 (The latter isn't grokked by some PCC-based compilers.)
1480 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1482 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1483 * nindy-share/coffstrip.c
1484 Added some forward declarations (otherwise, gcc complains
1485 about implicit extern redefined as static).
1487 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1489 Changes inspired by Per Bothner:
1490 * printcmd.c (print_address_symbolic): Take additional parameter
1491 specifying whether to demangle.
1492 (print_address): Pass in asm_demangle to control demangling.
1493 (print_address_demangle): New fn, takes explicit arg to control
1495 * utils.c: Add new vars demangle and asm_demangle, and let them
1497 (fputs_demangled): If !demangle, just print the argument.
1498 (fprint_symbol): If !demangle, just print raw symbol.
1499 * valprint.c (val_print): Call print_address_demangle rather than
1500 print_address, to cause demangling to depend on the global
1501 rather than assembler-level demangling setting.
1502 * WHATS.NEW, gdb.texinfo: Document.
1504 * main.c (show_command): Show all settings if no arg.
1505 (initialize_main): Make "info set" the same as naked "show".
1506 * command.c (cmd_show_list): Handle prefix commands in the
1507 list, and print the name of the setting as well as its English
1508 description and value.
1510 Allow gdb functions to specify where a line should wrap if it
1511 exceeds the size of a terminal line. Use it to make the output
1513 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1514 of the right size when screen width changes.
1515 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1516 (wrap_here): New fn, indicates a point in the output where we
1517 should wrap the line rather than just letting it overflow at a
1519 (fputs_filtered): Implement wrapping.
1520 (n_spaces): New fn, returns a pointer to N spaces.
1521 (print_spaces_filtered): Use n_spaces.
1522 * defs.h (n_spaces): Declare.
1523 * stack.c (print_frame_info): Wrap with 4-space indent after
1524 fn name and before filename and line number.
1525 * printcmd.c (print_frame_args): Wrap with 4-space indent
1526 before each argument name is printed.
1527 * valprint.c (value_print): Wrap with no indentation before
1529 (val_print_fields): Wrap with indentation relative to nesting
1530 level before each field name.
1531 (val_print): Wrap with nesting indentation before array elements.
1532 * command.c (do_setshow_command): Avoid extra newlines,
1533 wrap with 4-space indent around values printed, end with period.
1534 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1536 * breakpoint.c (breakpoint_1): Implement addressprint for
1537 "info breakpoints" display. Change file name and line number
1538 format to " at file:nnn" rather than " (file line nnn)".
1539 * gdb.texinfo: Document.
1542 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1544 Frozen for gdb-3.92.6 release.
1546 README, WHATS.NEW: Update for 3.92.6 release.
1548 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1549 coffread.o from configs since it is now built by default.
1550 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1551 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1552 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1553 from configs since it is now built by default.
1555 Makefile.dist: Update for release 3.92.6. Handle files that
1556 have been moved to ../include, ../getopt, or ../bfd. Add
1557 saber.suppress and tests directory. Add config.status to
1558 the release (it will say "none").
1560 coredep.c: Minor formatting fixes.
1562 These changes were made in early December but only checked in now:
1563 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1564 nindy-share/nindy.c: lint
1565 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1566 register values coming back from the target; we store values
1567 in target byte order everywhere.
1569 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1571 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1573 * valprint.c (cplus_val_print, val_print_fields): New functions,
1574 which print C++ objects. They conspire to avoid printing a
1575 virtual base class more than once, following all the twists and
1576 turns of C++ virtual base rules.
1577 (val_print): Call the above rather than do it by hand.
1579 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1580 symbol file, not for added files like shared libs. This really
1581 needs to be generalized to a timestamp per file.
1583 * core.c (cleanup_core): Avoid coredump if no core file.
1585 * config.gdb: Accept -host or -target in place of +host or
1588 * coffread.c (find_linenos): Avoid desupported BFD interface
1589 to line numbers. We still read them manually rather than using
1590 BFD's "generic" features.
1592 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1594 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1596 * Makefile.dist: Eliminate use of $< in explicit targets.
1598 * readline/Makefile: Use $< rather than $*.c, which does not
1599 include the VPATH in GNU Make.
1601 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1602 copies of tconfig/i960, added for global configuration
1603 compatability. All i960 versions can read both coff and b.out.
1605 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1606 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1609 * TODO: Think of more things to do.
1611 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1613 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1614 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1615 64-bit float conversion.
1617 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1618 equivalent to sun?os4 so global config works.
1620 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1624 * main.c: Only declare linesize once; declare pagesize not at
1625 all, since it is never used.
1626 (main): Clear newly allocated line before it is used.
1628 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1630 Further stabilization for the Intel 960.
1632 * Makefile.dist: Parameterize the location of the "include"
1633 and "bfd" directories, as well as "getopt". Add symfile.c.
1634 Link in both dbxread and coffread. Fix up "make depend" to
1635 rewack the locations of include, bfd, and getopt in its output.
1637 * README: Document moving include files, improve some of
1640 * coffread.c: Move common code out to symfile.c. Change
1641 symbol_file_command style interface to use new *_symfile_init
1642 and *_symfile_read interface under BFD. Use BFD internal
1643 info to locate line table, symbols, etc.
1645 * core.c (core_fetch_registers): Rename to get_core_registers
1646 to avoid confusion with fetch_core_registers.
1647 (register_addr): Move to coredep.c, which is already machine
1648 dependent. This leaves core.c pretty clean of dependencies.
1650 * coredep.c (register_addr): Accept this routine from core.c.
1652 * dbxread.c: Move common code (with coffread.c, etc) into new
1653 symfile.c. Each psymtab now contains a pointer to the
1654 format-dependent function that knows how to read it in. Make
1656 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1657 (process_one_symbol): Add code to complain about a "compiler bug
1658 we muzzle here", if we actually see it.
1660 * eval.c (evaluate_subexp): Insert missing "break" statements
1661 in code that determines whether a variable is an lvalue in
1662 memory, register, or whatever. I detected this via a compiler
1663 bug in which it *almost* mashed out the whole switch statement.
1665 * gdb-int.texinfo: Add minor sections on configuring gdb for
1666 release, and about the README file.
1668 * infcmd.c (registers_info): Fix formatting somewhat. Still
1669 not as pretty as before, but it handles byte swapping.
1671 * remote-nindy.c: If data cache routines are interrupted while
1672 waiting for the remote end, be sure that any uninitialized cache
1673 blocks are on the free list, not on the valid list!
1675 * symfile.h: Flesh out this header file with all the various
1676 routines and variables that have been merged in from dbxread.c
1677 coffread.c, and symtab.c to symfile.c.
1679 * symfile.c: New file, containing code common to dbxread.c,
1680 coffread.c, and some code from symtab.c. All generic code for
1681 reading symbol files should be in here now.
1682 (unrecord_misc_function): Remove unused function.
1684 * symtab.h: Remove file-reading things to symfile.h.
1686 * symtab.c: Remove file-reading things to symfile.c.
1688 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1689 to decode i960 fault types.
1691 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1692 target.c: Change type of the "resume" function from int to void,
1693 since its result was never used.
1695 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1697 * main.c: Replace "stupid" with "caution"; you now "set caution
1700 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1702 * infcmd.c (do_registers_info): Call val_print to deal with the
1703 byte order of the registers being printed. FIXME, this makes
1704 the formatting of the output uglier.
1706 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1707 defined, call it for signals the debugger doesn't itself use.
1708 The i960 uses this for more detailed fault information.
1710 * remote.c (remote_open): If arg is null, print help rather than
1713 * sparc-xdep.c (register_valid): Avoid declaring size, since
1714 various modules will think of various sizes depending on the
1715 architecture of their tm-file. FIXME, we need protection against
1716 actually entering one of those modules, which would clobber
1717 storage if not for the target architecture compiled into gdb.
1719 * stack.c (up_command, down_command): Always print the frame
1721 (up_silently_command, down_silently_command): New commands
1724 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1726 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1727 more parameters than it used to.
1729 * findvar.c (registers): Increase slop to 256 bytes, which should
1730 protect us against even most RISC machines with large register
1732 (locate_var_value): Move declaration inside related ifdef.
1734 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1735 throughout, to avoid throwing away buffered input from the board.
1736 (nindy_wait): Supply_register takes addr_of_value, not value.
1737 (i960_print_fault): Renamed from i80960_fault.
1738 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1739 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1741 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1742 we can set the PC in the call to proceed(). Unpush nindy_ops
1743 before pushing it on top, to avoid message to user. Eliminate
1744 commentary from Unix machines that just misleads here.
1745 (reset_command): Fix error message to suggest target command.
1747 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1749 Release 3.92.5 as frozen.
1751 Stabilize the merged release...with help from lint, Saber C,
1754 Everywhere: Add include files needed to declare return types
1755 of functions called.
1757 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1759 * breakpoint.h: Add undeclared breakpoint functions, and some
1760 functions for display handling since I couldn't think of a better
1763 * breakpoint.c (insert_breakpoints): Make code for disabling
1764 shared library bkpts more likely to work. It's used when we
1765 rerun a program and stop before the shared library has been
1767 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1768 cast from pointer, so it squeezes through catch_errors.
1769 (bpstat_stop_status): Fix logic broken some time ago. We now
1770 always create a bpstat if the stop address matches a breakpoint,
1771 even if we don't stop there -- just like the old code used to do
1772 before I got my fingers into it (sigh).
1773 (breakpoint_1): Print "ignore count" after "stop only if"
1774 condition, since that's how it actually works.
1775 (mention): Handle watchpoints as well as breakpoints.
1776 (watch_command): use set_raw_breakpoint and mention to do most
1777 of the work (and initialize all the fields!). Only pass one
1778 arg to parse_c_expression, since that's all it takes.
1780 * command.c (not_just_help_class_command): Rename arg to args
1781 since we ignore "unused argument" warnings on vars named "args".
1782 inflow.c (child_terminal_info): ditto.
1783 infptrace.c (kill_inferior): ditto
1784 main.c (catch_errors, version_info, quit_command, pwd_command,
1785 source_command, dump_me_command, editing_info,
1786 set_history_size_command, set_history, show_history,
1788 stack.c (locals_info): ditto
1789 target.c (target_files_info): ditto
1790 valprint.c (set_input_radix, set_output_radix): ditto
1792 * core.c: Remove old variables for handling core and exec file
1793 sections (data_start, data_end, stack_start, stack_end,
1794 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1795 text_end, exec_data_start, exec_data_end, text_offset,
1796 exec_data_offset, data_offset, stack_offset). They're
1797 superseded the more general build_section_table and
1799 (get_exec_file): Mention the `file' command.
1800 (read_memory_check): Rename to memory_error, and only call it
1801 in the case of an actual error.
1802 (read_memory, write_memory): call memory_error.
1803 (core_fetch_registers): Register section name is ".reg".
1805 coredep.c: Remove a bunch of crud now that all this file does
1806 is pull the registers out of a core file.
1807 (fetch_core_registers): Rewrite to actually work, I hope.
1809 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1810 Replace index() with strchr(). Remove all the pre-BFD macro
1811 definitions for accessing the symbol file.
1812 (struct dbx_symfile_info): Encapsulate the information that
1813 dbx_symfile_init needs to pass to dbx_symfile_read in this
1816 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1817 dbx_symfile_discard): Rearrange symbol file reading to divide
1818 the format-specific part from the format-independent part,
1819 leaving the format-independent part such as file name expansion
1820 and opening in symtab.c. This replaces
1821 partial_symbol_file_open and partial_symbol_file_read.
1822 Symbol_file_read, add_file, add_file_target_command,
1823 add_file_addr_command move to symtab.c. Pass an explicit
1824 "mainline" flag for when reading the main symbol table, rather
1825 than relying on the offset address to be zero or nonzero.
1827 (dbx_symfile_read): Don't allow void *'s to be printed as
1829 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1830 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1831 macro" debug version really work.
1832 (read_dbx_symtab): Remove unref'd parameter inclink.
1833 Avoid swapping N_SLINE symbols, for speed.
1834 Merge N_TEXT!N_EXT case with the other external symbol
1835 definitions' case. Add comments.
1836 (start_psymtab): Allocate the symfile name in the psymtab on
1837 the psymbol_obstack, rather than using the caller's storage.
1838 (end_psymtab): Only allocate a dependencies list if there are
1840 (psymtab_to_symtab_2): Use BFD when reopening file to read
1841 its symbols for real.
1842 (read_struct_type): Add FIXME comments where it needs work
1844 (read_huge_number): Add FIXME about overflows.
1845 (read_range_type): Add FIXME about comparing a long to 1<<32.
1847 * coffread.c: Minor changes to move things closer to the new
1848 regime with symtab.c and dbxread.c Major work is still needed
1851 * exec.c (exec_file_command): Remove old variables (see core.c
1853 (xfer_memory): If memory transfer is right at the end of a
1854 section, don't lose.
1856 * findvar.c (get_saved_register): If value is in a real
1857 register, LVAL is lval_register, not lval_memory.
1859 frame.h: Declare print_sel_frame and record_selected_frame.
1861 gdb-int.texinfo: New file, for GDB internals documentation.
1862 Very simple, unformatted doc of cleanups is there for now.
1864 gdbcore.h: Remove obsolete variables that described a.out
1865 section addresses and offsets. (See core.c above.)
1866 Declare fetch_core_registers and registers_fetched.
1868 getopt.c: Declare char *alloca(); even on SPARC.
1870 infcmd.c (run_command): Call target_kill rather than
1872 (step_command, next_command, stepi_command, nexti_command):
1873 Declare from_tty parameter even though we don't use it.
1874 (run_stack_dummy): argument BUFFER is a char array, not
1875 a pointer to REGISTER_TYPE.
1876 (finish_command): using_struct_return needed a value *,
1877 not a struct symbol *.
1879 * infptrace.c (child_xfer_memory): To avoid dependency on
1880 where sections are in memory, try PT_WRITE_D and if that fails,
1881 try PT_WRITE_I. Most Unixes don't care which you use.
1883 * infrun.c (step_resume_break_shadow): Change to array to
1884 match other breakpoint shadow storage.
1885 (clear_proceed_status): Pass address of bpstat to
1886 bpstat_clear, not the bpstat itself.
1887 (child_create_inferior): FIXME comment about if the child
1889 (start_inferior): Remove old function.
1890 (child_open): Use target_kill rather than kill_inferior.
1891 (wait_for_inferior): Ditto.
1892 (insert_step_breakpoint, remote_step_breakpoint): Use
1893 new step_resume_break_shadow.
1895 * inftarg.c (child_wait): If all child processes die,
1896 pretend that the one being waited for exited with signal 42.
1898 * main.c (command_line_input): When scanning for comments,
1899 don't coredump on unclosed quotes.
1900 (quit_command): Use target_kill rther than kill_inferior.
1901 (_initialize_main): Rename class_user from "user" to
1904 * printcmd.c (print_command_1): Initialize "fmt" if no format
1905 is specified by the user.
1906 (print_frame_args): Only add to args_printed if we are
1907 actually fetching args from the stack (avoiding undefined
1909 (_initialize_printcmd): Remove bogus \{ from string.
1911 * remote-eb.c (eb_open): Avoid coredump on no argument.
1913 * remote-nindy.c: Bring out of Intel environment into new
1914 target environment. Remove all conditional compilation on
1915 I80960. Massive hacking throughout.
1916 (nindy_xfer_inferior_memory): New routine stolen from
1918 (nindy_create_inferior): New routine pieced together, probably
1919 not quite working yet.
1920 (nindy_ops): New target_ops struct for nindy.
1922 * remote-vx.c: Use write_memory rather than target_write_memory
1923 to get error checking.
1924 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1926 (vx_create_inferior): Use target_terminal_ours...
1928 * signame.c (_initialize_signame): Always initialize, since
1929 we need the table for things other than psignal.
1931 * solib.c (solib_add): Use symbol_file_add, not add_file.
1932 (solib_address): Return boolean result rather than struct
1933 pointer which nobody else knows the type of.
1935 * sparc-tdep.c, valops.c: Use write_memory rather than
1936 target_write_memory, to get error checking.
1938 * stack.c (locals_info, catch_info, args_info,
1939 get_selected_block, frame_command, up_command): Use
1940 target_has_stack, rather than have_inferior_p or
1943 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1945 * symfile.h: New file, defining the interface between the
1946 generic and object-file-specific symbol reading code.
1948 * symtab.c: Move generic symbol-reading interface to symtab.c,
1949 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1950 table to map BFD targets to symbol-reading modules in GDB.
1951 Change index to strchr.
1952 (lookup_struct_elt_type): Use error() rather than hand-made
1953 simulations thereof.
1954 (lookup_partial_symbol): Speedup slightly when length == 0.
1955 (symbol_file_add): New function.
1956 (symbol_file_command): Call it.
1957 (symfile_open, symfile_init): New function.
1958 (add_file_target_command, add_file_addr_command): moved from
1961 * target.c (target_command): use target_kill.
1963 * target.h (target_files_info): Don't declare, never called
1966 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1967 files to determine stack end address.
1969 * valarith.c (value_x_binop, value_x_unop): Change error message
1970 to be more useful. Pass proper argument to value_struct_elt.
1972 * valops.c (value_assign): FIXME comment that long long
1973 bitfields will break here.
1975 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1976 Update `make saber_gdb' to work better.
1978 * TODO: A woman's work is never done.
1980 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1981 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1982 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1983 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1984 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1985 valops.c, valprint.c, exec.c: Lint.
1988 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1990 Continuing Intel 960 port merge of GDB.
1992 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1993 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1994 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1995 Wack over "make depend" so it handles files in subdirectories
1996 vx-share, nindy-share, bfd, and in the current directory.
1998 * blockframe.c (get_prev_frame_info): Remove fatal error
1999 if stack not defined.
2001 * core.c (core_open, core_detach): New functions that handle
2002 the old "core-file" command as "target core" and "detach" instead.
2003 (core_file_command): Call them.
2004 (core_xfer_memory): Use common routine xfer_memory.
2006 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2007 dbxread now uses bfd for everything but symbol reading itself.
2008 BFD internals are used to drag out the relevant file offsets.
2009 (partial_symbol_file_open): Change args all around for BFD.
2011 * symtab.c: Rename "value" to "val" everywhere, so we can
2013 (symbol_file_command): New command, moved from dbxread.c
2014 and coffread.c. It uses BFD to read the file, then vectors
2015 based on its type, to dbx or coff symbol readers.
2016 * symtab.h: Extern a few vars for symbol_file_command.
2018 * target.h: Breakpoint takes a char * save area, not a char **.
2020 * valprint.c (val_print): When unpacking bitfields, offset
2021 the address in gdb of the value, if it is declared with a shorter
2022 type. Remove the last "runtime kludge test" of host byte order.
2024 * utils.c: Remove old my_bfd_read routine.
2026 * stack.c (frame_info): Use target_has_stack. Print program counter
2027 register's actual name rather than "pc", since it's called the
2028 "ip" (instruction pointer) on the i960 (sigh).
2030 * target.c (target_command): Add command for selecting a target
2031 type and calling its open routine. This is used for initiating
2032 communication with a particular target, in a generic way.
2034 * tm-i960.h: Update for modern gdb. Remove semicolons from
2035 various macros. Handle reading struct return convention, and
2036 error-out attempts to return structs with the "return" command.
2037 Be sure gdb doesn't think we know how to call functions in the
2040 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2041 to i960_xxx in lower case.
2042 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2043 not being defined yet.
2045 * remote.c (remote_open): Call start_remote to initialize
2046 wait_for_inferior during open.
2047 (remote_xfer_inferior_memory): Return length written rather
2050 * remote-vx.c (target_command -> vx_open): Use new generic
2052 * remote-eb.c, inftarg.c, exec.c: ditto.
2054 * infrun.c: Fix comments.
2055 (attach_program -> child_open): Use new generic target command.
2056 (wait_for_inferior): Clear saved register values before target_wait,
2057 so target_wait can set some of them if convenient.
2059 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2060 Return success indicator, not void.
2061 (child_xfer_memory): Avoid fetching initial word if we'll
2062 overwrite it anyway.
2064 * infcmd.c (attach_command): Use new generic target open routine.
2065 (_initialize_infcmd): Update doc on attach and detach commands.
2066 (do_registers_info): Merge in a byte-order problem as a FIXME
2069 * findvar.c (find_saved_register): Avoid problem in current frame.
2070 (read_relative_register): Ditto.
2071 (write_register): Convert byte order on the way out.
2073 * exec.c (file_command): Add.
2074 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2075 (xfer_memory): Common function between core_xfer_memory and
2077 (exec_xfer_memory): Use it.
2079 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2081 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2082 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2083 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2085 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2087 Merge Intel 960 port of gdb, continuing...
2089 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2090 symbol_file_command): Pass from_tty arg to hush 'em up.
2092 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2093 Add magic numbers for 960 COFF format.
2095 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2097 Merge Intel 960 port of gdb, from Intel "1.2" release.

2115 More cleanup of batch mode; specifically, execute "-s", "-e", and
2116 "-se" switches as soon as they are encountered on the invocation line.
2118 Fri Apr 20 13:47:15 PDT 1990
2121 Thu Apr 19 09:54:28 PDT 1990
2122 Add 'reset' command.
2124 Wed Apr 18 09:48:07 PDT 1990
2125 After opening remote tty, wait for 1 second to go by without input
2126 from it before trying to talk to NINDY (fixes problems with the
2127 Heurikon HK80/V960E).
2129 Mon Apr 4 16:33:05 PDT 1990
2130 Some output was not being suppressed in 'batch' mode.
2132 Thu Mar 22 15:31:11 PST 1990
2133 Ask user if old symbol table should be deleted when new file is
2136 Allow user to run a program downloaded before gdb960 was brought up.
2138 Correct "exec-file" help message for i80960 context.

2157 Mon Oct 23 12:03:04 PDT 1989
2158 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2160 Mon Oct 16 14:15:09 PDT 1989
2161 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2163 Mon Oct 2 15:56:31 PDT 1989
2165 Added 960CA disassembly support.
2167 To simplify maintenance:
2168 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2170 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2171 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2172 - made disassembly interface identical to that in gdmp960.
2176 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2178 * target.h: Allow targets to stack. Add target_has_memory,
2179 _registers, etc. Restructure memory access and "info files"
2180 to walk the target stack.
2181 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2182 target.c: Change tables to match target.h.
2183 * inflow.c (child_mourn_inferior): pop child_ops.
2184 (generic_mourn_inferior): Use new has_stack flag.
2185 * infptrace.c (child_xfer_memory): New memory regime.
2186 * inftarg.c (child_files_info): New "info files" regime.
2187 * remote-eb.c: New memory regime, new info files.
2188 * remote-vx.c: New memory regime, new info files. Now use
2189 separate targets for VxWorks attachment to machine, and
2190 actually running a process under VxWorks, since one has
2191 stack & execution & regs and the other doesn't.
2192 * remote.c: New memory regime, new info files.
2193 * sparc-xdep.c (fetch_core-registers): New memory regime.
2194 * target.c: New routines and support for stacked targets,
2195 new memory regime, new info files regime.
2198 Generalize section handling for an arbitrary number of sections,
2199 including use of the new BFD (binary file) library.
2200 * gdbcore.h: Add struct section_table.
2201 * exec.c (build_section_table): Iterate all sections and
2202 record what gdb needs to know about them.
2203 (exec_command): Use it.
2204 (exec_xfer_memory): Use the table.
2205 (exec_files_info): Print the table.
2206 * core.c (core_file_command, core_xfer_memory, core_files_info):
2208 * source.c (find_source_lines): Use bfd_get_mtime.
2209 * dbxread.c: Quick changes to make it compile with new BFD.
2210 * utils.c (error): Avoid using bfd_error in generic routines.
2212 * core.c (core_fetch_registers): Get from the ".regs" section of
2214 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2216 * inferior.h (attach_flag): Export.
2217 * infcmd.c (run_command): use new target_create_inferior.
2218 * infrun.c (child_create_inferior): Don't return result.
2219 * Makefile.dist (VERSION): 3.91.4.
2221 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2223 * breakpoint.c (bpstat_num): Handle breakpoints which have
2224 since been deleted, such as temporary breakpoints.
2225 infcmd.c (program_info): ditto.
2227 * core.c (core_file_command): Display the frame where the core
2232 * remote-vx.c (target_command): Merge in target command from
2233 targ-vx.c. A few other cleanups.
2235 * TODO, Projects: Lots more stuff to do...
2237 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2239 Massive changes to wall off the remote-debugging interface
2240 behind a function vector. The port to handle VxWorks targets
2241 is also part of this.
2243 All files: Replace references to renamed functions,
2244 remove references to remote_debugging, remove references to
2245 have_include_file, have_core_file in favor of target_has_stack,
2246 target_has_memory, etc.
2248 * Modularize the breakpoint interface.
2249 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2250 a breakpoint instruction.
2251 breakpoint.c: struct breakpoint's shadow_contents now sized as
2253 (insert_breakpoints): Vector to target to install breakpoints.
2254 (remove_breakpoints): Vector to target here too.
2255 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2256 sparc-tdep.c (single_step): Use new breakpoint interface for
2257 the single-step breakpoints.
2258 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2259 New file, contains routines to insert and remove breakpoints by
2260 reading out the old contents and later replacing them. This is
2261 how ptrace breakpoints work, and many remote systems as well.
2263 * tm-vxworks68.h: New config file, overrides a few things for
2264 Wind River's preferences.
2266 * target.h: New file, for transfer vector used to talk to the
2267 inferior (child, attached, core, exec, remote, etc). All accesses
2268 to the thing being debugged should come through these vectors.
2269 target.c: New file, routines to handle transfer vector.
2270 (various files): Add transfer vectors XXX_ops for the various
2271 targets and pseudo-targets (core files, etc) we support.
2273 * breakpoint.c (bpstat_stop_status): Further explorations of
2274 watchpoints and why things don't work all the time.
2275 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2277 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2278 the local gdbinit if it doesn't already have it.
2280 * core.c (core_ops): add and install.
2281 Allow core debugging without exec file.
2283 * dbxread.c (free_and_init_header_files): Merge two fns.
2284 (end_symtab): Free named symbol table when a new version comes in.
2285 (read_dbx_symtab): Relocate all kinds of symbols with base
2286 address. First step toward handling different text, data, bss
2288 (add_file_addr_command): Renamed add_file_command.
2289 (add_file_command): Vector to remote handler.
2290 Add "load" as an alias for "add-file" command.
2292 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2293 non-returning functions.
2295 * exec.c: Add exec_ops, and push it as a target when an exec
2298 * infcmd.c (run_command): Pass executable file name and arg list
2299 separately when starting an inferior. Permit "run" when no exec
2300 file is specified, for VxWorks.
2301 (detach_command): Move to child_detach in inftarg.c.
2303 * inftarg.c: New file. Unix-child-specific routines, and the
2304 child_ops structure.
2306 * inferior.h (registers): Export "registers" as the way for
2307 target dependent register handlers to find gdb's local copy of
2308 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2309 since it is now used by places that want wait_for_inferior to
2310 handle the grunge but want to see every trap from the inferior.
2312 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2313 Eliminate remote_debugging hooks in terminal handling.
2315 * infrun.c: Replace start_inferior with child_create_inferior.
2316 Move all the hair of Unix shells and ptrace idiosyncracies into
2317 child_create_inferior, so remote handlers don't have to deal.
2318 Remove running_in_shell. Rename stop_after_attach to
2319 stop_soon_quietly, and use it in a few other places where we want
2320 to just call wait_for_inferior and get control back on the first
2321 trap. trap_expected now never takes a value > 1.
2322 (init_wait_for_inferior): Initialize static vars when a new
2325 main.c (gdbinit): Add new hook for .gdbinit file name, let
2326 it be overridden by config files as GDBINIT_FILENAME.
2327 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2328 Both of these are used for VxWorks gdb.
2330 mcheck.c: rename include file "gmalloc.c" to avoid problems
2331 with system include file "malloc.c".
2333 param-no-tm.h: New include file, same as param.h but does not
2334 include the default "tm.h" file. This is used in files where
2335 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2337 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2339 remote-vx.c: New file, VxWorks remote debugging support. Uses
2340 RPC routines that are shared with the target system, in directory
2343 remote.c: Vectorize remote interface.
2345 source.c: Globalize source_path, and make an alias "l" for "list"
2346 since we now have the "load" command.
2348 sparc-xdep.c: Use new param-no-tm.h.
2350 symmisc.c (free_named_symtab): Add new function from Wind River.
2351 However, ifdef it out for now while we think about what it should
2354 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2356 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2357 non-Unix-children handle this with their own code in the target
2360 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2361 source and target lists. Add vx-share to default list of include
2362 directories. Add new files to src and target lists: mem-break,
2363 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2364 ${srcdir} versions of munch and createtags are used.
2366 * valops.c (find_function_addr): Split out of call_function.
2367 (call_function_by_hand): Rename call_function; this function
2368 calls functions in the target by laboriously patching the target
2369 word-by-word with the right stack, args, regs, etc.
2372 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2374 Handle AMD 29000 a bit better.
2376 * remote-eb.c (readchar): Mask received char log to make it readable.
2377 (remote_start): Pass arguments down to executing program.
2378 Make startaddr unsigned.
2379 infrun.c (start_inferior): Accept args, pass them to
2381 infcmd.c (run_command): Pass args down to start_inferior.
2383 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2384 the target object file format.
2385 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2387 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2388 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2390 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2392 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2393 * TODO: We did a few things, we have more to do though.
2395 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2396 * inflow.c (inferior_died): Clear deferred stores.
2398 * Debug problems with dummy frames and calls to the inferior.
2399 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2400 * sparc-tdep.c (do_restore_insn): Simplify.
2401 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2402 (sparc_push_dummy_frame): Simplify and fix what we push.
2403 (sparc_pop_frame): Slightly more hair here, deciding whether
2404 we are restoring a saved PC or returning to a return address in %i7.
2405 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2407 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2408 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2409 * obstack.h (chunkfun): ditto.
2410 * defs.h (xmalloc, xrealloc): ditto
2412 * utils.c (quit): Grab the terminal from the child if necessary.
2414 * inflow.c (term_status_command): Rename to term_info, change
2417 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2418 (is_delayed_branch): Speed up.
2419 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2420 Still missing some float ops, and needs testing.
2422 * Support for input and output radixes other than base 10
2423 * defs.h (input_radix, output_radix): Declare.
2424 * expread.y (yyparse, parse_number): Handle changes of input
2425 radix, and ambiguous names-or-numbers in radixes >10.
2426 * printcmd.c (print_scalar_formatted): Print formatted hex
2427 numbers in varying column widths.
2428 * valprint.c (val_print): Use output_format to print scalar ints.
2429 (set_input_radix, set_output_radix, set_radix): Create.
2430 (set_output_radix): Set output_format from output_radix.
2431 (_initialize_valprint): add `set radix' but leave the others off.
2433 * main.c (execute_command): Let stupid questions be turned off.
2434 (_initialize_main): Handle "set stupidity", etc.
2436 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2437 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2439 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2441 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2442 bfd stuff is still screwed up, but with some manual work, it
2445 * breakpoint.c (bpstat_do_actions): Start over if a command
2446 proceeds the inferior, since the inferior will have stopped and
2447 will need to have its new stop-actions taken care of.
2449 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2450 compiler fits, simplify it.
2452 * gdb.texinfo (directory command): Doc new dir command.
2453 source.c (directory_command): "dir" now puts things on the front
2454 of the path, moves dups up front, and handles multiple names
2455 on the command line, inserting each one in order. It also
2456 blows away cached line and full_filename info.
2458 * stack.c (backtrace_command): Skip "more stack frames follow"
2461 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2462 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2463 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2464 The only odd one was Gould NP1, which had defined vprintf to
2468 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2469 variable, inspect_it.
2470 valprint.c (print_string, val_print): Use the global inspect_it
2471 to indicate whether to print in Epoch style or normal style.
2473 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2475 * printcmd.c (call_command): add an alias for the "print" command
2476 which runs expressions and doesn't print the result if void.
2477 (print_command_1): implement it.
2479 * command.c: Remove #if 0'd code. Initialize all the fields
2480 in add_cmd (). Rename do_nothing_command to
2481 not_just_help_class_command, and make it externally visible.
2482 command.h: add user_commands to struct.
2483 * main.c (define_command): Don't overload c->function with a char
2484 string as well as a function pointer.
2486 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2487 calling convention of value_struct_elt () that got dropped in
2490 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2491 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2493 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2495 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2496 until a good time (e.g. when we are about to run the child),
2497 saving ptrace calls.
2498 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2499 * tm-sparc.h: define DO_DEFERRED_STORES.
2501 * sparc-xdep.c (store_inferior_registers): when storing float
2502 registers, don't store stack regs too. When storing the SP,
2503 however, DO store the stack regs too. This fixes a bug in which
2504 the dummy frame is not recognized when a call_function finishes,
2505 because its frame pointer (in the stack regs) was never
2507 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2508 even though we don't know how to read them from an inferior.
2509 valops.c (call_function): Comment about storing SP.
2511 * infrun.c (save_inferior_status): Save away the original bpstat
2512 chain so it can be restored later. Install the copied version for
2513 use by whoever saved the status. It will be blow away by
2514 restore_inferior_status, and the original chain restored. This is
2515 important for people who have pointers into the original.
2517 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2518 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2519 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2522 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2524 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2525 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2526 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2528 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2530 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2531 Store the baseclasses in a type struct starting from array element
2532 0 rather than from the unusual array element 1.
2534 dbxread.c: the above.
2535 (virtual_context): Add
2536 Read new debug information about which virtual function table
2537 a virtual function is from, and store it in fn_field.fcontext.
2539 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2540 TYPE_FN_FIELD_STATIC_P.
2542 symtab.c: the above.
2543 valops.c: the above. Handle pointer casts of object *'s.
2544 (search_struct_method): Add.
2545 (value_struct_elt): First arg is now a pointer to a value, and is
2548 valprint.c: the above.
2549 values.c (value_virtual_fn_field): Add type arg. Handle
2550 offsetting to the proper object when calling virtual fns.
2552 (baseclass_addr): Add valuep arg.
2554 * README: Document the current state of BFD config (missing).
2555 * TODO, ChangeLog, Makefile.dist: Roll version.
2556 * WHATS.NEW: Add summary of changes since 3.5.
2558 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2560 * dbxread.c (read_struct_type): Clear bit vectors whenever
2562 symtab.c (B_CLRALL): define.
2564 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2565 using == rather than =. Huh... This fixes the dreaded problem
2566 wherein builtin_type_int becomes TYPE_CODE_FLT.
2568 * core.c (info_files): Show the inferior pid.
2570 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2571 already knows how to look in the source directory.
2573 * Remove psymtab hair from many places. Remove duplicated code
2574 for searching symbol tables. Hide psymtabs from most places.
2575 Make it fast to get from a psymtab to its symtab.
2577 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2578 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2579 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2580 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2581 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2582 new symtab completely. New psymtabs get symtab pointer
2583 initialized to zero. Remove MI warning printf.
2584 symtab.h: Comments. Add psymtab to symtab pointer.
2585 (PSYMTAB_TO_SYMTAB): New macro.
2586 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2587 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2589 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2591 (print_frame_info): Avoid special-casing symbols that have not yet
2594 * source.c (open_source_file): Quick path if we have already
2595 located the source file by its full name.
2597 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2598 find_pc_psymtab. When a name is found in the misc function
2599 vector, search the symbol table for its mangled name, not the
2600 name that the user typed.
2602 * bfd.h: Fix missing comment terminators, make #endifs match.
2604 * valarith.c (value_less): Handle unsigned int comparisons.
2605 Add FIXME about pointer compares, which assume host and target
2606 pointers are the same.
2608 * command.c (do_nothing_command): lint
2609 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2610 fix comments on debug symbol format for visibility. Actually set
2611 visibility of symbols.
2612 main.c (echo_command): lint; use <readline/history.h>.
2613 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2614 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2615 pointing past end of allocated memory; saber complains.
2616 obstack.h: Declare the external functions that we use.
2617 valarith.h: use <string.h>
2618 solib.c (solib_add): lint.
2620 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2622 * main.c (initialize_main): Default info_verbose to off, now that
2623 symbol reading is fast.
2624 (quit_command): Avoid clobbering exec_bfd while quitting.
2626 * Initial BFD (binary file diddling library) merger:
2627 coffread.c: Change AOUTHDR to struct exe_hdr.
2629 core.c: initialize initialized data at compile time.
2630 (core_file_command): Move from coredep.c, convert to bfd.
2631 (xfer_core_file): Convert to bfd.
2632 exec.c (exec_file_command): use bfd routines.
2634 mips-tdep.c: Remove exec_file_command and friends.
2637 * coredep.c: (fetch_core_registers) Convert core_file_command to
2638 fetch_core_registers.
2639 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2641 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2642 (my_bfd_read): More bogosity, which I don't think we call.
2643 (program_name): Remove this atrocity asap!
2645 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2648 values.c: allocate_repeat_value was not clearing the
2649 optimized_out field.
2650 (value_static_field): minor stylistic fix (wrong macro was used).
2651 valops.c (value_struct_elt_for_address): didn't work for C++
2654 * signame.c (_initialize_signame): Initialize signal names once.
2656 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2657 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2658 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2660 * remote-eb.c: Support user-settable baud rates on the serial port.
2662 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2664 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2666 * tconfig/sun3os4: Remove warning about native assembler,
2667 since it also occurs in the xconfig file.
2669 * findvar.c (registers): Allocate some slop after `registers'
2670 to prevent stray accesses from trashing the next variable.
2672 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2673 on the sun-3, by changing the #ifdef from `sun3' (which is not
2674 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2675 vars, which happened to follow `registers' in the executable.
2677 * readline/history.c (history_search): Heed gcc-2's advice
2678 and parenthesize && inside ||).
2680 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2681 tm-29k.c: Insert FSF copyright headers.
2683 * remote-eb.c: Better comments.
2685 * Makefile.dist: Update to 3.91.6.
2686 * TODO: note PREPARE_TO_STORE problem.
2688 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2690 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2692 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2694 * infrun.c (wait_for_inferior, at end): Don't set up
2695 prev_* if the inferior no longer exists.
2697 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2698 CANNOT_EXECUTE_STACK.
2699 valops.c (call_function): Use it.
2701 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2703 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2704 infrun.c (wait_for_inferior, 2 places): Use it.
2706 * values.c (value_being_returned): Only use
2707 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2709 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2710 right thing for remote-eb.c.
2712 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2713 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2715 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2716 (FRAME_FIND_SAVED_REGS).
2718 * findvar.c ({fetch,store}_registers): Check for
2719 REMOTE_{FETCH_STORE}_REGISTER macro.
2721 * findvar.c (get_saved_register): Add argument lval and
2722 change meaning of argument addr.
2723 findvar.c: Change calls to get_saved_register to reflect
2724 new calling convention.
2725 valops.c (value_assign): Use get_saved_register instead of
2726 find_saved_register.
2728 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2730 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2731 an (uninitialized) pointer to one. Use "&" when passing it
2734 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2736 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2739 * coffread.c (symbol_file_command): Put semicolon after
2741 Put safe_to_init_tdesc_context in #if defined (TDESC).
2742 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2743 coffread.c: #include <sys/stat.h>.
2744 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2745 Add missing ')' in check for "lc%" and friends. Remove
2747 Declare read_one_sym() at top of file.
2748 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2749 MC68WRMAGIC can have the same value without causing a duplicate
2752 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2754 * Allow a Makefile to be built without building the
2755 tm and xm file links that screw up builds in subdirectories.
2756 This is done with `config.gdb none', then you can do things
2757 like `make gdb.tar.Z'.
2758 * tconfig/none: Config file for no target system
2759 * xconfig/none: Config file for no host system
2760 * config.gdb: If no TM or XM files are called out by the
2761 host or target file, don't make links for them.
2763 * cplus-dem.c: Add documentation.
2765 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2766 simple error, so the user's gdb doesn't crash due to some object
2767 file problem (e.g. somebody is rebuilding the file out from under
2770 * printcmd.c (print_address_symbolic): demangle the symbol.
2772 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2773 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2774 (alldeps.mak): sort and uniq all results from this; duplicates
2775 hose gdb.tar.Z link building. Remove RCS files from
2776 tconfig and xconfig. Add config files for sun386. Add
2777 a few odd files to OTHERS and HFILES.
2779 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2781 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2782 Roll version number to 3.91.5. Make lint work in bindir.
2784 * README: Document cross-debugging and new file structure.
2786 * blockframe.c: Lint. Include "value.h" to declare read_register.
2787 (find_pc_partial_function): remove duplicate line.
2789 * command.h: Lint. Declare error_no_arg and dont_repeat.
2791 * tm-news.h: Remove inadvertently duplicated stuff.
2793 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2794 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2796 * config.gdb: Allow `config.gdb host target' form. Clean
2797 up previous change that printed bogus messages when you just said
2800 * core.c: #include "command.h" for lint.
2803 * main.c: Remove some casts of enums. Lint.
2810 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2812 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2813 read it from memory. This will allow us to save ptrace calls
2814 eventually. Changed caller single_step too.
2816 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2817 that we aren't going to use, saving many ptrace calls, especially
2818 when watchpointing or single stepping. Use some #define's for
2820 (store_inferior_registers): Ditto.
2821 (core_file_command): Use some #define's for constants.
2823 * tm-sparc.h: Add #define's for some register numbers, so we
2824 can eliminate the use of random constants in sparc-xdep.c.
2826 * stack.c (frame_command, print_frame_info, up_command,
2827 down_command) Remove frame_changed, since it
2828 causes a bug and doesn't seem to do anything useful. In some
2829 places it was used as a flag, in others as a stack level (?).
2831 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2832 default is to use the portable (vprintf) version rather than the
2834 * xm-news.h (MISSING_VPRINTF): Add.
2836 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2838 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2840 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2841 about linking debugged programs -Bstatic in the sun?os4 config
2842 files in tconfig and xconfig subdirectories.
2844 * main.c (main): Remove unreached exit(0) now that we exit
2847 * Create TODO file for online bug list. There are too many
2848 "little" bugs to keep track of on paper.
2851 rather than kingdon@ai.
2853 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2855 * Makefile.dist (VERSION): 3.91.4 now.
2857 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2858 (condense_misc_bunches): Add sanity check that misc_count is
2859 the same as the number of symbols in the bunch.
2861 * coffread.c: rename init_misc_bunches. Pass an argument
2862 to condense_misc_bunches (a zero).
2864 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2865 every time we are called; don't rely on our caller to do it.
2866 (add_file): Remove call to init_misc_bunches.
2868 * mipsread.c: Only warn, don't error, if unknown symbol types.
2869 This keeps an old gdb from falling on its face if it sees newly
2870 extended symbol info. Rename init_misc_bunches.
2872 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2874 * Merge in changes from Per Bothner for DECstations and other
2875 MIPS stuff. The rest is Bothner speaking:
2877 The next message is a merger of Alessando Forin's mips port with
2878 mine. I've tried to use my good if biased judgment to get
2879 the best of both. It *does* need testing.
2881 Some of the changes are general, *not* mips-specific.
2884 Didn't believe in little-endian bit order.
2885 There are still inconsistencies about whether flags
2886 like BITS_BIG_ENDIAN are integer (#if ...) or
2887 boolean (#ifdef ...). I tried to paper over them.
2889 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2890 Moved some misc_function code that was common to
2891 {dbx,coff,mips}read.c to symtab.c.
2892 In the process, I think I cleaned things up a bit.
2893 At the same time, moved obsavestring and obconcat to symtab.c.
2896 Removed obsolete condense_addl_misc_bunches (use
2897 condense_misc_bunches(1) instead).
2900 Needed to include <sys/dir>, at least on DECstations.
2902 valops.c, mips-tdep.c, tm-mips.h:
2903 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2904 conventions (when STACK_ALIGN is insufficient).
2905 Needed on mips, where doubles need 8-byte alignment,
2906 but ints only need 4.
2909 Removed cruft that was not being used.
2913 Print $ before register-names (I think that makes things a little
2915 Never print two instructions, even if one delays.
2916 Removed hex-disassemble set_cmd. (This is not mips-specific,
2917 so I think the argument is whether it is generally worthwhile or not.
2918 I'm inclined to think not, given how easy it is to
2919 convert between radixes in gdb.)
2922 This is basically Alessando's code.
2923 It doesn't use obstacks; I changed it to use obstacks
2924 in a few minor places where using malloc causes a
2925 memory leak. (Probably, more places could/should be changed.)
2926 I added record_misc_function where it was missing.
2927 In symbol_file_command and add_file_command, I tried
2928 to make the code consistent with more recent versions.
2929 Minor sylistic changes in parse_procedure.
2930 Make a .gdbinfo. psuedo-symbol point back to the real
2931 procedure symbol (using the isym field).
2934 This is basically from my port, but with a lot of details
2935 and a number of routines merged in from Alessando's version.
2936 I basically used my code "raw" backtrace (use heuristics
2937 from the actual code, rather than symbol table info) - though
2938 the idea is Alessandro's. I feel my code is a little cleaner
2939 here, particularly in being a little more flexible, such as being
2940 able to handle gcc-produced code (which it now can).
2941 It also doesn't do frame caching (which is not useful
2942 more recent gdb versions).
2943 I also used my code for push_/pop_dummy, more or less.
2944 I tried to incorporate AF's code for testing sigtramp
2945 while backtracing; I probably got it wrong.
2946 Added mips_print_register, which tries to scrunch as much
2947 information as possible on a screen...
2948 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2949 under mips-pinsn.c), I don't see anything mips-specific here,
2950 and I don't see it being all that useful anyway.
2953 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2954 Use more register names (rather than hard-cases numbers).
2956 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2958 * Hack up 3.90.11 changes:
2960 * Makefile.dist (depend): parameterize $(GCC).
2961 Add solib.c and solib.o.
2962 (readline): Fix vpath for both absolute or relative SRCDIR.
2965 Also, let the part I didn't understand at least compile so
2966 I can test the rest. FIXME.
2968 * dbxread.c: Fix thinko using strcmp.
2969 (init_psymbol_list): declare static.
2970 (partial_symbol_file_open): Comment cleanups better, avoid
2971 cleaning up the string table since the caller will do that.
2972 Move the stat for mod time into symbol_file_command, temporarily.
2973 (There should be a mod time for each symbol file, eventually,
2974 to control its rereading. FIXME.)
2976 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2977 SunOS, which gives error for shared libs otherwise. (From
2978 Schaefer, probably FIXME needs work for portability.)
2980 * solib.c: Move #include "param.h" to work.
2981 Lowercase all the Uppercase Letters In the Messages.
2982 (find_solib): Clean up inferior_so_name for debug printouts.
2983 Allow no argument, to mean all shared libraries.
2985 * symmisc.c: include param.h to get CLEAR_SOLIB.
2987 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
2989 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
2990 to 3.90.11. ChangeLog entries below are from this.

3019 * Changes for Sun shared libraries:
3020 blockframe.c (find_pc_partial_function): If a non-text symbol
3021 is found, set *address = pc - FUNCTION_START_OFFSET.
3022 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3023 Disable breakpoints instead of giving an error.
3024 source.c (select_source_symtab): Initialize cs_pst.

3030 (record_misc_function): Give correct type for N_DATA symbols.
3031 (condense_misc_bunches): do "misc_function_count = j" regardless
3033 Take code which is shared between symbol_file_command and
3034 add_file_command and put it into partial_symbol_file_{open,read}.
3035 Split add_file_command into add_file_command and add_file.
3036 Make psymtab_to_symtab read in the string table if the file
3038 Two new parameters to read_dbx_symtab and start_psymtab.
3039 tm-sunos.h: New file.
3041 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3046 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3048 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3050 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3052 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3053 size 1,2,4,8 rather than size < 8.
3055 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3056 as necessary, not just once.
3058 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3060 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3062 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3064 * tm-news.h: Add CALL_DUMMY_*.
3066 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3068 * config.gdb: In list_host, list_target, use ${i}, not $i.
3070 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3072 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3074 * sparc-opcode.h: Change all store floating-point state register
3075 instructions to have the right match & lose fields.
3077 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3079 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3081 config.gdb: If srcdir != ., create readline directory and
3082 copy a makefile into it.
3084 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3085 consistency with POSIX.
3087 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3088 when we exit its exp_valid_block.
3090 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3092 * Makefile.dist: Bump version to 3.91.3.
3094 * Clean up handling of breakpoint commands (somewhat).
3095 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3097 inferior.h: Add breakpoint_proceeded to inferior status struct
3098 and globals; save it and restore it.
3099 (clear_breakpoint_commands): Cleanup, remove old #define.
3101 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3102 (save_inferior_status, restore_inferior_status): handle it also.
3103 (proceed): Remove earlier code that set breakpoint_proceeded.
3104 It is now set only in clear_proceed_status.
3105 (clear_proceed_status): Cleanup, use bpstat_clear rather
3106 than clear_breakpoint_commands. No callers need the stop_bpstat
3107 between clear_proceed_status and proceed.
3109 infcmd.c: Add breakpoint_proceeded definition and comment.
3110 (cont_command, jump_command, signal_command): Move call to
3111 clear_proceed_status right next to call to proceed.
3113 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3114 caller's argument while running down the chain of breakpoints.
3115 Use new variable "breakpoint_proceeded" to determine when
3116 a command that it executes moves the inferior past the
3118 (bpstat_clear): Handle NULL argument.
3119 (bpstat_clear_actions): Avoid useless call to
3120 breakpoint_auto_delete.
3121 (delete_breakpoint): Clean up bpstat's that are pointing to
3122 the deleted breakpoint from the stop_bpstat chain.
3123 (breakpoint_auto_delete): Simplify.
3125 * Clean up handling of EOF, error on stdin, etc. This was
3126 prompted by a network problem that caused gdb to go into an
3127 infinite loop filling up its malloc'd memory.
3129 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3130 not clear_breakpoints_commands, which is now gone.
3131 (main): If command_loop returns (e.g. from EOF on stdin), do
3132 a quit_command (looping back to command_loop if quit_command
3133 doesn't really quit).
3134 (command_loop): check result from command_line_input and
3135 exit if it returns NULL, rather than passing the NULL to
3137 (gdb_readline): Free malloc'd result space before returning
3140 * utils.c (query): Handle C-d to mean "yes", just as if the
3141 input was not a terminal. Also avoid infinite loop if EOF
3142 occurs in mid-input-line before newline. This allows
3143 query to be used at EOF on stdin with reasonable results.
3145 * infrun.c (proceed): Set breakpoint_proceeded.
3147 * values.c (value_as_long): Avoid infinite recursion for enums.
3148 (_initialize_values): Fix typo in help msg (kingdon).
3150 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3151 RL_LIB for linking. This allows -lreadline for linking
3152 and nothing for dependencies, once readline is a real library.
3154 * config.gdb: Jim Kingdon: give useful error message if the
3155 host or target type is not recognized.
3157 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3158 it just defines it. Dumb, but deal with it.
3160 * Jim Kingdon suggests:
3161 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3163 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3165 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3167 * Clean up Bothner's changes.
3169 * blockframe.c (clear_pc_function_cache): New function.
3170 * blockframe.c: remake cache_pc_function_* static.
3171 * dbxread.c (symbol_file_command): remove references to
3172 cache_pc_function_* variables.
3173 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3174 * printcmd.c: Avoid kludging a global variable (addressprint)
3175 to avoid printing the address of a string twice. Instead,
3176 pass the format letter 's' down low enough that it can be seen
3177 to avoid this problem.
3178 (print_formatted): Pass format arg to value_print.
3179 (restore_addressprint): Remove function.
3180 (do_examine): Avoid hacking addressprint, cleanups and such.
3181 (print_frame_args): Add a comment to a Bothner change.
3182 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3183 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3184 to wipe out the values cached in blockframe.c.
3185 * symtab.c (find_method): Add comment saying how big you must
3186 allocate to be "big enough". Per being terse again.
3187 * valprint.c (val_print): Handle format letter "s" to print
3188 strings without addresses. Add comment to vtbl printing code
3189 which casts with wild abandon. Rearrange reference-printing
3191 @0xaddr: value (print w/addressprint)
3192 value (print w/~addressprint)
3193 @0xaddr (parameter lists w/addressprint)
3194 or nothing (parameter lists w/o addressprint)
3196 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3198 * Merge more changes from Per Bothner:
3200 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3201 annoying) that I tried to improve it. Here are my suggestions.
3203 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3206 Do automatic de-reference when taking the address of a reference.
3208 Don't deref_ref when printing parameter lists.
3210 More attempts at treating refernences properly.
3212 In val_print, if deref_ref==0, don't print dangling " = ".
3214 Add COERCE_REF macro, which de-references an REF.
3216 * Merge changes from Per Bothner:
3218 * Fixed (Sony news)-specific configuration problems.
3219 * Fixed other problems with using vanilla pcc and libc (enum problems;
3220 assumption that vsprintf exists).
3221 * Some major speed-ups (finc_pc_partial_function now caches a match;
3222 parsing avoids duplicate symbol_lookup calls).
3223 * Changed handling of baseclasses (no longer use baseclasses field
3224 of struct type, use the first n_baseclasses fields instead).
3225 * Various minor changes/fixes, most C++-related.
3228 Cache the most previous match from find_pc_partial_function.
3229 (Save both low and high ends of matching function's pc range.)
3230 This speeds up the loop of infrun.c:wait_for_inferior quite
3231 a bit, and makes step/next commands much zippier.
3233 Added an enum->int cast (otherwise, some compilers barf).
3235 No longer set baseclass offset to 0, since multiple
3236 inheritance now mostly works.
3237 Added a number of casts, to shut up compiler warnings
3238 (after stabs where made enums, not ints).
3239 When discarding a symbol table (in symbol_file_command),
3240 must clear the cache introduced in blockframe.c.
3241 Don't convert $vtbl_ptr_type to vtbl any more.
3242 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3243 Mask off sign bit emitted by g++ for virtual table offset.
3244 Set voffset to -1 (not 1) for static member functions.
3246 Changed parsing/lexing of names to avoid doing symbol lookup twice
3247 (once when lexing to determine symbol class, once for real).
3248 Now only call symbol_lookup once. Fields of 'this' win especially big.
3250 Subpress printing addr twice in the case of 'x/s addr'.
3252 lookup_basetype_type is no longer used.
3253 Add find_methods as recursive helper function to decode_line_1.
3254 This allows multiple inheritance to work.
3255 Also, once one or more matches has been found, do not look in
3256 base-classes. (Baseclass methods would be overridden, anyway.)
3258 Removed baseclasses array in struct type.
3259 Instead of using baseclasses[i], use fields[i-1].
3260 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3261 Changed sign convention of voffset (previous was inconsistent).
3263 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3265 Used to assume existence of vsprintf. Re-written to not need it
3266 if HAVE_VPRINTF is undefined.
3268 typecmp was too pessimistic. Made it less so.
3270 Don't print space after address.
3271 If vtable points to a misc symbol (with 0 offset), print it,
3272 since that indicates the actual class of the object.
3273 Changed ype_print_derivation_info to use new inheritance
3274 scheme (without baseclasses vector).
3276 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3277 Also, changes needed because TYPE_BASECLASSES were removed.
3279 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3281 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3284 If there is no path set, and the symbols don't indicate what directory
3285 a file was compiled in, look in the current directory. But either
3286 a path or a known compilation directory will prevent this.
3289 Three independent bug fixes:
3290 * Remove the #if 0 block that breaks some stuff.
3291 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3292 adapt gdb to either SunOS 4.0.* or 4.1.
3293 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3296 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3299 (type_print) Demangle the name being printed.
3300 (type_print_base) Handle botched demangling without coredump (tiemann).
3303 (check_stub_method): Document routine.
3304 (tiemann) fix bug for no-arg functions
3305 Avoid clobbering beyond end of malloc'd storage.
3306 Terminate the argument list properly.
3310 * Changes merged by John Gilmore:
3313 In breakpoint_1, use new print_address_symbolic instead
3314 of find_pc_partial_function. (This forces use of assembler-level
3315 addresses, and avoids misleading non-mangled source-level names.)
3317 Generalize ansi argument such that -1 means skip arglist totally.
3318 Removed global variable print_ansi_qualifiers (which made
3319 code non-reentrant), in favor of extra explicit arguments
3320 to internal routines.
3322 Add new helper function print_address_symbolic.
3323 Use find_pc_misc_function instead of find_pc_partial_function
3324 (since we want assembler-level symbols here).
3326 Print unknown function as just "f (...)", not "f (...) (...)".
3327 Use new fputs_demangled explicitly.
3329 Fixed a typing violation (problem: value.h cannot be imported
3330 without renaming many variable in this file).
3331 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3332 decode_line_1: Moved forward some never-reached code.
3333 Made decode_line_2 skip function prologues correctly.
3335 fputs_filtered should not demangle by default.
3336 Add new fputs_demangled to demangle on demand..
3338 Change value_struct_elt to use value_primitive_field (using recursive
3339 utility function search_struct_field). This allows foo.bar to work
3340 for multiple inheritance (so far only for data fields).
3341 Change check_field in the same way (recursive helper function
3342 to support multiple inheritance).
3343 (Note: there are more of these problems that I haven't fixed.
3344 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3345 value_of_this: 'this' symbol name is now just "this", note "$this".
3347 Don't print static members.
3348 Avoid printing "members of <type>" if there are none.
3349 Simplified type_print_derivation_info by merging duplicate code.
3350 Remove useless blank lines in type_print_base (ptype command).
3352 Added declaration of new routine value_primitive_field.
3354 Added value_primitive_field which is generalized version of
3355 value_field that can handle multiple inheritance (non-zero offsets etc).
3356 Re-implemented value_field to call value_primitive_field.
3358 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3360 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3361 delete the whole environment. Karl Berry reported the bug.
3362 * source.c - fix openp to avoid //'s in filenames, which
3363 trigger an Emacs bug causing it to not be able to find files
3364 when running gdb in a window.
3365 * dbxread.c - zap the #if 0 that botches the add-file code.
3366 It seems to work a lot better without all the code commented out.
3368 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3370 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3373 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3375 * Makefile - added a ${CFLAGS} to a couple of entries,
3376 added remote-sa.sparc.c
3377 * added remote.sa-sparc.c, a modification of remote.c
3378 which conducts a dialog directly with the SparcStation prom.
3379 * breakpoint.c, infrun.c, sparcdep.c added
3380 remote_insert_breakpoint(), and remote_remove_breakpoint()
3381 to breakpoint.c instead of directly writing breakpoint instructions.
3382 * sparcdep.c on remote_debugging,there is no need
3383 to remove signle step breakpoint instructions.
3384 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3386 * printcmd.c - epoch interface sends lisp expressions to open up
3387 epoch windows on inspection.
3388 * valprint.c - added arrayprint, and addressprint and made adding
3389 format controls easier
3390 * wait.h added a couple of undef's because we were getting
3391 complaints about WSTOPSIG and WTERMSIG begin redefined.
3394 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3396 * symtab.c (decode_line_1): Add support for handling method stubs
3397 in the type information.
3399 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3401 * values.c (baseclass_addr): Run loop from INDEX+1 to
3402 N_BASECLASSES; otherwise, we can still get into a loop.
3403 @@ This should be restructured to use a cleaner search strategy.
3405 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3407 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3408 abbreviation "Tt" for tags which have the same name as their
3411 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3413 * symtab.c (list_symbols): add ability to set breakpoints on all
3414 the functions which match a particular regular expression.
3416 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3418 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3419 should print ANSI qualifiers (such as `const' and `volatile').
3420 All callers changed to call with ANSI == 1, except from
3421 `check_method_stub', which uses old-style syntax.
3423 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3424 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3426 * values.c (check_stub_method): New function.
3428 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3430 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3431 * valprint (type_print_base): Ditto.
3433 * symtab.c (gdb_mangle_typename): New function.
3435 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3437 * breakpoint.c (catch_command): New function. Provides a
3438 mechanism to set breakpoints based on catch clauses.
3439 (disable_catch): Similar, but disables breakpoints on catch
3441 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3443 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3445 * blockframe.c (blockvector_for_pc): New function.
3446 * blockframe.c (block_for_pc): Changed to call
3447 `blockvector_for_pc' and get the block itself.
3449 * stack.c (catch_info): New function. Prints info about
3450 exceptions which can be caught in the current frame.
3451 * stack.c (print_frame_label_vars): New function. Similar to
3452 `print_frame_local_vars'.
3453 * stack.c (print_block_frame_labels): Prints out labels that are
3454 defined in this frame. These labels are exceptions that can be
3457 * dbxread.c: Updated to handle N_CATCH symtab types.
3459 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3461 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3462 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3463 when printing the type.
3465 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3467 * valprint.c (val_print): Use `baseclass_addr' to access the
3468 baseclasses pointed to via the derived class object at VALADDR.
3470 * values.c (baseclass_addr): New function. Casts derived pointers
3471 to baseclass pointers taking virtual baseclasses and multiple
3472 inheritance into account.
3474 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3478 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3480 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3481 exp_valid_block field correctly.
3483 * infrun.c (wait_for_inferior): When checking "don't even think
3484 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3485 also check step_resume_breakpoint.
3486 Insert breakpoints and continue (not step) if
3487 step_resume_break_address != NULL, even if another_trap.
3488 If trap_expected and we enter sigtramp, then set up a
3490 If trap_expected is set when we hit the step_resume_break,
3492 When calling resume and trap_expected says tell resume to step
3493 (2 places), also check step_resume_break_address.
3495 * infrun.c (wait_for_inferior): Don't set
3496 prev_{pc,sp,func_{start,name}} before calling wait ().
3497 Do set them after exiting loop.

3499 (start_inferior): Initialize them.
3501 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3503 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3504 Restore old code which distinguishes between trap_expected and
3505 running_in_shell, just make the latter take any non-TRAP signal,
3508 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3510 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3511 xconfig/3b1 (CC,PINSN_CC): Define.
3513 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

3532 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3534 * value.h: Add optimized_out field and change lazy field to
3535 char. Add macro VALUE_OPTIMIZED_OUT.
3537 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3538 instead of stuffing things in buffers (oappend, etc).
3540 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3541 execute_command, exit both loops.
3543 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3545 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3547 * Makefile.dist (RAPP_OBS, rapp),
3548 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3550 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3552 * valops.c (value_struct_elt), values.c (value_static_field):
3553 Change error messages to remove references to `info methods'.
3555 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3558 infrun.c (start_inferior): Add START_INFERIOR_HOOK.

3570 findvar.c (get_saved_register): New function.
3571 findvar.c: Rewrite code which called find_saved_register to
3572 call get_saved_register instead.
3574 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3576 * valprint.c (val_print): Change error message printed when
3577 the type has TYPE_FLAG_STUB set.

3585 Fri Apr 20 11:31:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3587 * findvar.c (write_register): Add PREPARE_TO_STORE.
3588 {sun3,sparc,symmetry}-xdep.c (PREPARE_TO_STORE): Add.
3589 infptrace.c, {mips,pyr,symmetry,sun3,arm,hp300hpux}-xdep.c
