481 for each structure argument rather than assuming it's either
482 true or false for all structure arguments.
484 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
485 on the length structure passed, not the compiler used.

520 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
522 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
523 improve remote debugging efficiency. Also fixed problems with
524 doing function calls for programs with no entry points.
525 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
527 * inferior.h (PC_IN_CALL_DUMMY): ditto.
528 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
529 parse_lines): Pass section_offsets info to these routines so that
530 we can relocate symbol table entries upon readin.
531 * (psymtab_to_symtab_1): Set symtab->primary to tell
532 objfile_relocate to do relocations for our symbols.
533 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
534 (which hang off of the symbol table).
535 * Use prim_record_minimal_symbols_and_info instead of
536 prim_record_minimal_symbols to supply section info to make minimal
537 symbol relocations work.
538 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
539 -1, try to deduce it from ms_type.
540 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
541 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
542 add code to relocate objfile->sections data structure.
543 * remote.c (get_offsets): Use new protocol message to acquire
544 section offsets from the target.
545 * (remote_wait): Get rid of relocation stuff. That's all handled

560 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
561 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
562 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
563 sparc-tdep.c compiles).
564 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
567 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
569 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
570 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
571 * configure.in: Recognize m68*-cisco*-*.
573 * Makefile.in (TAGS): Use variables directly, rather than using
574 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
575 and means that these filenames no longer need be unique across all
576 the config/* directories.
577 * configure.in: Put the config/*/ into TM_FILE, etc.
579 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
580 and trapv exceptions.
582 * target.h (struct section_table), objfiles.h (struct obj_section):
583 Change name of field sec_ptr to the_bfd_section. More mnemonic
584 and avoids the (sort of, for the ptx compiler) name clash with
585 the name of the typedef.
586 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
587 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
589 * utils.c: Include readline.h.
590 * Makefile.in (utils.o): Add dependency.
592 * remote.c (getpkt): Add support for run-length encoding.

596 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
598 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
600 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
601 prim_record_minimal_symbol.
604 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
605 computing their offset from the start of the old buffer and adding
606 to the new buffer, rather than by assuming we can add the
607 difference between the old buffer and the new buffer (it might not
608 fit in an int). Merge in cosmetic differences from emacs regex.c
609 version of this macro.
611 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
613 * Makefile.in (install-only): Fix use of program_transform_name.
615 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
617 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
618 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
619 so I'm nuking the command.
620 * symtab.c (find_addr_symbol): Comment out, no longer used.
622 * main.c (main): Don't init_source_path for the -cd argument. Now
623 that source_path doesn't contain the current_directory from when
624 GDB started up, init_source_path is no longer useful (and is
625 harmful because it clobbers a source_path set in $HOME/.gdbinit).
627 * TODO: Remove item about line numbers being off. It is useless
628 and confusing without a reproducible test case (it mentions
629 proceed(), but I was able to step through proceed without trouble).
631 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
633 For Sunos 4.x targets, enable gdb to set breakpoints in shared

635 symbols from stripped executables.
636 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
637 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
638 symtab.c (list_symbols): Handle mst_solib_trampoline.
639 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
640 for all targets, remove IBM6000_TARGET dependencies.
641 * dbxread.c (read_dbx_dynamic_symtab): New function.
642 * dbxread.c (dbx_symfile_read): Use it.
643 * dbxread.c (SET_NAMESTRING): Set namestring to
644 "<bad string table index>" instead of "foo" if the string index is
646 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
648 * symtab.c (list_symbols): Take from_tty as parameter and pass it
649 to break_command. Handle mst_file_* minimal symbol types.
650 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.

658 * environ.c (set_in_environ): Eliminate special handling of PATH and
660 * putenv.c: Removed, conflicts with system declaration of
661 putenv on RS/6000 running AIX 3.2.5, and above change makes it
663 * Makefile.in: Change accordingly.
664 * procfs.c (procfs_create_inferior): Change comment accordingly.

673 (get_i387_state): Use memset not bzero.
677 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
678 ieee-float.h to floatformat.h.
680 * valprint.c (val_print_string): Ignore error if the error
681 happened after a terminating '\0'.
683 * c-valprint.c (c_val_print): Never add 1 to return value from
684 val_print_string; just return what it returns.
686 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
687 looping through all of the enums.
688 * infrun.c (signals_info): Use it.
690 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
692 * main.c (main): When printing warning about bad baud rate, don't
693 use warning(); it relies on current_target which isn't set up yet.
695 * breakpoint.c (_initialize_breakpoint): Update docstring for
696 tbreak to match what the code actually does. Don't mention tbreak
697 in docstrings for "enable once" or "enable breakpoints once".
699 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
701 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
702 while (0). That defeats the whole purpose of using do . . . while (0).
703 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
704 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
705 using a ?: expression as an lvalue is not portable.
707 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
708 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
709 'p' and 'r' symbol descriptors into a single symbol to look for a
711 * README, config/sparc/tm-sparc.h: Update comments.
713 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
715 * mdebugread.c (parse_type): Do not complain for types with
716 an `indexNil' aux index, these are simply undefined types.
717 Remove indexNil check from caller of parse_type.
718 * mdebugread.c (parse_partial_symbols): Do not enter
719 stGlobal, scCommon symbols into the minimal symbol table, their
720 value is the size of the common, not its address.
721 Handle scInit, scFini, scPData and scXData sections.
722 Use minimal symbol type mst_file_* for stLabel symbols, instead of
724 Enter stProc symbols into the global_psymbols list once, not into
725 the static_psymbols_list.
726 Get rid of dummy psymtab if it is empty, to allow proper detection
727 of stripped executables.
728 * mdebugread.c (cross_ref): Allow cross references to Fortran
731 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
733 * stabsread.c (common_block_end, fix_common_block): Stash the
734 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
735 as to not assume that a pointer fits in an enum.
737 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
739 * os9kread.c (fill_sym): check compiler verion number for pre-
741 * os9kread.c (os9k_process_one_symbol): address of symbol is
742 relative to section not module.
743 * stabsread.c (define_symbol): add symbol type 's' as local

752 the command be able to accept more than one filenames.
753 * target.c (target_link): check if failed to link with rombug.
754 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
756 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
758 * remote-es.c (es1800_child_ops): Don't declare it static.

772 * dbxread.c (end_psymtab): Remove old and commented out
773 capping_global and capping_static. Fix comments regarding
774 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
776 * parser-defs.h: Add "extern" to start of variable declarations so
777 we don't end up with commons.
778 * parse.c: Define these variables.
780 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it

816 alphabetic character as the start of a name.
818 * sparclite/Makefile.in (all install): Build and install aload.

859 remove_breakpoints_on_following_step, check
860 through_sigtramp_breakpoint as well as step_resume_breakpoint.

864 * os9kread.c (os9k_process_one_symbol): Rename
865 VARIABLES_INSIDE_BLOCK to OS9K_VARIABLES_INSIDE_BLOCK.
866 * symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
867 (CORE_ADDR)0, from target_link, since that is what it uses.
868 Process name at end, not during parsing (like we did before Kung's
869 change), so that -readnow and -mapped can appear anywhere.
870 Make text_relocation a local variable.
871 * config/i386/i386os9k.mt: Fix comment.
872 * Makefile.in (ALLDEPFILES): Add remote-os9k.c.

915 * target.c (target_link): new function to get relocation info when
916 a symbol file is requested to load.

935 * solib.c (find_solib): Update to use new interface.
936 * irix5-nat.c (find_solib): Read o_path from inferior
937 (clear_solib): Free storage for o_path.

954 (STEP_SKIPS_DELAY): Added.
955 * infrun.c (proceed) [STEP_SKIPS_DELAY]: Check for a breakpoint in
958 * valprint.c (val_print_string): If errcode is set, always print
959 an error, regardless of force_ellipsis. In the non-EIO case,
960 just print the error message rather than calling error(). Don't
961 access *(bufptr-1) if bufptr points to the start of the buffer.
962 When looking for '\0', don't increment bufptr and addr if bufptr
963 started out already at limit. If an error happens on fetching the
964 first character, don't print the string.

1004 if we hit a bp_through_sigtramp breakpoint. Remove kludge which
1005 ignored bs->stop for a bp_step_resume breakpoint.
1006 * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
1007 which performs one (the check_sigtramp2 one) of the functions
1008 which had been handled by the step_resume_breakpoint. For each
1009 use of the step_resume_breakpoint, make it still use the
1010 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
1012 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
1013 When setting the frame address of the step resume breakpoint, set
1014 it to the address for frame *before* the call instruction is
1015 executed, not after.
1017 * mips-tdep.c (mips_print_register): Print integers using
1018 print_scalar_formatted rather than duplicating all the

1021 read_register and then putting it back in target format with

1023 an error rather than have some registers overwrite other
1025 #if 0 unused include of opcode/mips.h.
1027 * symfile.h: Don't declare arguments for coff_getfilename.
1029 * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

1044 Wed Feb 23 16:28:55 1994 Jeffrey A. Law (law@cygnus.com)
1046 * tm-hppa.h (CALL_DUMMY): Add two NOP instructions to the end of

1074 * symmisc.c (dump_psymtab): Fix typo, clean up output of section
1075 offsets. Cast psymtab->read_symtab to PTR before passing it to
1077 * i386-tdep.c (i386_skip_prologue): Skip over instructions that
1078 set up the global offset table pointer in pic compiled code.
1079 * config/mips/tm-mips.h (FIX_CALL_DUMMY): For big endian targets,
1080 error() on TYPE_CODE_FLT arguments whose size is greater than 8,
1081 swap all other TYPE_CODE_FLT arguments as mips_push_arguments
1082 ensures that floats are promoted to doubles before they are pushed
1085 Fri Feb 18 23:12:59 1994 Stu Grossman (grossman at cygnus.com)
1087 * sparclite/Makefile.in, sparclite/salib.c, sparclite/sparclite.h:
1088 Fixup cache_on and flush_i_cache so that they work for both the
1089 930 and 932 processors. Rewrite most low level funcs (uart
1090 access & cache stuff) to use new ASI access macros in sparclite.h.
1091 Also make it easy to access second serial port.

1113 ourselves instead of worrying about INSTALL_XFORM. This enables
1114 users to override INSTALL_PROGRAM in the standard way.
1116 * Makefile.in (c-exp.tab.o, ch-exp.tab.o, m2-exp.tab.o): Don't
1117 depend on Makefile.in.

1205 * coffread.c (process_coff_symbol, case C_TPDEF): Don't set name
1206 of TYPE_CODE_PTR or TYPE_CODE_FUNC types. This parallels similar
1207 changes to stabsread.c from summer 1993.
1209 * remote-udi.c (udi_files_info): If prog_name is NULL, just skip
1210 printing the program, rather than passing NULL to printf.
1211 (udi_detach): Set udi_session_id to -1 so that udi_close doesn't
1212 try to call UDIDisconnect again. Print better message.
1213 (udi_kill): Just call UDIDisconnect ourselves, rather than doing
1215 (udi_create_inferior): If udi_session_id is negative, open a new
1216 TIP rather than giving an error.
1218 * config/mips/mipsm3.mh, config/i386/i386m3.mh,
1219 config/ns32k/ns32km3.mh: Define NAT_FILE.
1220 * config/nm-m3.h: Change guard from _OS_MACH3_H_ and _OS_MACH3_H
1221 (it was inconsistent and namespace-wrong) to NM_M3_H.
1222 * m3-nat.c (mach_really_wait): Change parameter name to ourstatus.
1223 (m3_open): New function.
1225 * TODO: Update Mach section.

1236 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
1237 rather than trying to shove an int into a pointer and back out
1238 again. This avoids compiler warnings.
1240 * defs.h (alloca): Declare as void *, not char *, on hpux.
1241 Don't prototype it, just declare the return type.
1243 Sun Feb 6 03:25:41 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1245 * config/i386/tm-sun386.h, config/i386/tm-symmetry.h

1250 * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
1251 ZERO_REGNUM, just read it as zero without talking to the board.

1255 * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
1256 to store_floating, not nonexistent variable len.
1258 * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):

1261 to provide old contents if the caller wants it.
1262 (mips_xfer_memory): Deal with errors from mips_store_word.
1263 * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
1264 define now that remote-mips.c doesn't use BREAKPOINT.

1268 mips_error, if executable file not specified.
1270 * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
1273 * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast

1278 * value.h (print_longest): Rename "value" to "val" in prototype
1279 declaration because some compilers don't like arguments whose
1280 names are the same as types.
1281 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
1282 before passing it to remote_*_bytes.
1284 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
1286 * h8500-tdep.c (saved_pc_after_call): The size of the

1289 change memory model.
1290 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
1292 * remote-hms.c (hms_load): Remove breakpoints when loaded.
1293 (hms_wait): Use new status structure

1321 * NEWS, README: Update to match 4.12 release.
1323 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1325 * command.c (empty_sfunc): New function.
1326 (add_set_cmd): Use it instead of not_just_help_class_command.
1327 (not_just_help_class_command): Change calling convention back to
1328 what it was before yesterday's change.
1330 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
1331 of the type if present.

1335 * printcmd.c (decode_format): Don't blithely set the size for
1336 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
1338 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
1339 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
1340 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
1341 always just check against INT_MIN and INT_MAX (this also fixes things
1342 if sizeof (long) > sizeof (int), e.g. Alpha).
1343 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
1344 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
1345 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
1346 BUILTIN_TYPE_UNSIGNED_LONGEST.
1347 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
1348 longest_int and longest_unsigned_int.
1349 * value.h (struct value): Just align to LONGEST, rather than worrying
1350 about CC_HAS_LONG_LONG.
1351 * valarith.c (value_binop): Figure out type ourself based on
1352 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
1353 point is that we don't depend on CC_HAS_LONG_LONG anymore.
1354 * valprint.c (val_print_type_code_int): Just call
1355 extract_unsigned_integer directly, rather than going through
1357 * printcmd.c (decode_format): Remove code which would sometimes
1358 change 'g' size to 'w' for integers. print_scalar_formatted handles
1359 printing huge integers well enough, thank you.
1361 * command.c (add_set_cmd, not_just_help_class_command): Change
1362 to make this the sfunc, not cfunc, since that is how we call it.
1363 * command.h: Comment difference between sfunc and cfunc.
1364 * demangle.c (set_demangling_command): Add third arg since that
1365 is how it is called.
1366 (_initialize_demangler): Use sfunc, not cfunc, for
1367 set_demangling_command, since that is how it is called.
1368 Remove show_demangling_command; it has no effect.
1370 * command.c (shell_escape): Report errors correctly (with error
1371 message from strerror).
1373 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1375 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
1376 x_scnlen.l rather than x_scnlen to match corresponding change in
1379 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1381 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
1382 Change comments regarding TYPE_CODE_BOOL.
1383 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
1384 regardless of the language.
1385 (value_true): Just call value_logical_not regardless of language.
1386 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
1387 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
1388 * language.h: Improve comment for la_builtin_type_vector.
1389 * m2-lang.c (_initialize_m2_language): Don't add any fields to
1390 builtin_type_m2_bool.
1392 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
1394 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
1395 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
1397 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1399 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
1400 by restarting the ioctl.
1402 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1404 * target.h (target_wait): Add comment about calling
1405 return_to_top_level.
1407 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1409 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
1410 additional arguments.
1411 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
1413 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
1415 * sparc-stub.c: Remove unnecessary #include of memory.h.
1417 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1419 * mips-tdep.c: Remove code which sets saved_regs from
1420 init_extra_frame_info and put it in new function mips_find_saved_regs.
1421 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
1422 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
1423 check if it is NULL and call mips_find_saved_regs if so.
1425 * remote-mips.c: Use unfiltered, not filtered, output most places.
1427 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
1428 backtrace. Revise comments.
1430 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1432 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
1433 alpha and irix. The _sigtramp case has to be handled properly
1434 in the tdep files if we have no ecoff debugging info.
1435 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
1436 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
1437 without PC_REGNUM kludge.
1438 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
1439 Clean up handling of mips sigtramp frames, improve comments.
1441 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1443 * paread.c (read_unwind_info): Fix typo.
1445 * paread.c (pa_symtab_read): Update the "check_strange_names"
1446 filter to match GCC's current output. Filter out section symbols
1447 (which the HP linker sometimes puts in the wrong place).
1449 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1451 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
1453 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
1455 * Makefile.in: Remove all references to sparcly-nat.c.
1457 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
1458 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
1459 duplicating serial.h and target.h.
1461 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
1462 are not used anywhere (a 5 Oct 1993 change removed the uses).
1464 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
1465 * config/m68k/es1800.mt: Add comment.
1466 * remote-es.c: Extensive changes to update to current conventions.
1468 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
1469 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
1470 to achieve the desired timeout.
1471 * serial.h (serial_t): Add field timeout_remaining.
1473 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1475 * c-exp.y (yylex): Reenable nested type code.
1477 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1479 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
1481 * remote-mips.c (mips_ops): Fix docstring.
1483 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
1485 * config/m68k/tm-monitor.h: Changes to bring this into accordance
1486 with the old tm-m68k-em.h:
1487 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
1488 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
1489 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
1490 Add FIXME regarding GET_LONGJMP_TARGET.
1492 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
1493 * infptrace.c (kill_inferior): Add comments.
1494 * main.c (quit_command): Call target_close after we kill or
1496 * remote-udi.c (udi_close): Don't error() if QUITTING.
1498 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
1500 * configure.in: Make m68k-coff and aout add monitor support in
1501 addition to the standard serial support.
1503 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1505 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
1508 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1510 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
1511 * elfread.c (record_minimal_symbol_and_info),
1512 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
1514 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1516 * i386-stub.c: Add ".text" right before "mem_fault:".
1518 * main.c (baud_rate): Add FIXME comment about printing -1 value.
1520 * remote-utils.c (usage): Fix message to be accurate and conform
1521 more closely to normal conventions.
1523 * remote-utils.c (gr_files_info): Have the exec_bfd test control
1524 whether to show information about exec_bfd, and not control whether
1525 to show information about device and speed.
1527 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
1528 usage message, don't dump core.
1530 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
1531 for variable size array.
1532 (bug_fetch_register, bug_store_register): Rename "value" to
1533 "fpreg_buf" because some compilers don't like variables whose
1534 names are the same as types.
1535 (bug_store_register): Use a cast when converting char * to
1538 * symmisc.c (maintenance_print_symbols): Don't refer to the name
1539 of the command in error message (the text was referring to the old
1540 name of the command).
1542 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
1544 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
1545 full details on structure elements without names. This partially
1546 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
1547 of those changes was accidental.
1549 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
1550 defined, make it an error to specify a single argument which is not
1553 * Makefile.in (version.c), main.c (print_gdb_version): Use
1554 host_alias and target_alias, not host_canonical and
1555 target_canonical, to print configuration.
1557 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1559 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
1560 of builtin_type_long. It is necessary to get a type which is
1561 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
1563 Fix many sins which will come up in 32 bit x 64 bit GDB, and
1564 various miscellaneous things discovered in the process:
1565 * printcmd.c, defs.h (print_address_numeric): New function.
1566 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
1567 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
1568 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
1569 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
1571 * utils.c, defs.h (gdb_print_address): New function.
1572 * expprint (dump_expression), gdbtypes.h: Use it.
1573 * breakpoint.c (describe_other_breakpoints),
1574 symmisc.c (dump_symtab, print_symbol):
1575 Use filtered not unfiltered I/O.
1576 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
1577 just run gdb under a debugger for this (and it had problems with
1578 printing addresses, how to print b->shadow, etc.).
1579 * buildsym.c (make_blockvector), core.c (memory_error),
1580 exec.c (print_section_info), maint.c (print_section_table),
1581 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
1582 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
1583 Add comments saying code is broken. Marked with "FIXME-32x64".
1584 * dbxread.c (process_one_symbol), partial-stab.h (default),
1585 remote-vx.c (vx_run_files_info):
1586 Don't cast int being passed to local_hex_string.
1587 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
1588 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
1590 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
1592 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
1593 * source.c: Include <sys/types.h> regardless of USG.
1595 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1597 * valops.c (value_assign): Set `type' after coercing toval.
1598 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
1599 Use extract_unsigned_integer to get the address of a reference.
1601 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1603 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
1604 AIX can use ? instead of \ for continuation. Deal with it.
1606 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
1607 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
1608 the HP compiler in ANSI mode doesn't like.
1610 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
1611 based on USG, rather than defining HAVE_SIGSETMASK to an
1612 expression containing defined. Having a macro used in #if expand
1613 to an expression containing "defined" is undefined according to
1614 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
1617 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
1619 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
1620 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
1622 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
1624 * ch-exp.y (match_string_literal): Allow a zero-length string.
1625 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
1627 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1629 * i386aix-nat.c (i386_float_info): Reverse order of registers before
1630 passing them to print_387_status.
1631 (print_387_status): Don't subtract top from 7 before using it.
1632 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
1633 from 7; the above explains it.
1635 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1637 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
1638 pointer value when fixing up the frame at the start of a function.
1640 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
1642 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
1643 Sparc from the stack.
1645 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1647 * remote-mips.c (mips_initialize): Clear mips_initializing via
1648 cleanup chain, not directly.
1650 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
1651 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
1652 munging the timeout due to the limited range of c_cc[VTIME].
1654 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
1655 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
1656 m3-nat.c (m3_create_inferior): Pass it.
1657 * procfs.c: Remove ptrace function. It was declared in a way which
1658 conflicted with the prototype in unistd.h on Solaris.
1660 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1662 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
1663 in the sigcontext if it is a signal trampoline frame.
1664 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
1665 Define for Solaris2.
1667 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
1669 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
1670 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
1671 tm-sparc.h so they can be overridden if necessary.
1673 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
1675 * lynx-nat.c: Add Sparc support.
1676 * sparcly-nat.c: Remove. It's useless.
1677 * config/sparc/nm-sparclynx.h: Rewrite.
1678 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
1680 * config/sparc/tm-sparclynx.h: Rewrite.
1682 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1684 * rs6000-pinsn.c: Use the new disassembler in the opcodes
1685 directory. Old code was discarded, since the new opcode table has
1688 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
1690 * Makefile.in (realclean): Remove info files per make-stds.texi.
1692 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1694 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
1695 if N_SO_ADDRESS_MAYBE_MISSING is defined.
1696 * config/sparc/tm-sun4sol2.h: Define it.
1698 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1700 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
1701 if we did not find a symbol.
1703 Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1705 * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
1708 * hppab-nat.c (call_ptrace): Delete redundant function.
1709 (kill_inferior, attach, detach, child_resume): Likewise.
1710 (child_xfer_memory): Likewise.
1712 * hppah-nat.c (call_ptrace): Delete redundant function.
1713 (kill_inferior, attach, detach, child_resume): Likewise.
1715 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
1717 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
1719 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
1721 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
1722 (CHILD_XFER_MEMORY): Define.
1723 (PT_*): Define so that generic infptrace.c code can be used.
1725 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1727 * xcoffread.c (xcoff_symfile_read): Make second parameter a
1728 struct section_offsets *, not a (nonexistent) struct section_offset *.
1730 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
1731 internal_xcoff_symtab, not an array of one of them. Change lots of
1732 "main_aux" to "&main_aux" and so on.
1734 * coffread.c, xcoffread.c: Include <coff/internal.h>
1737 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1739 * coffread.c (coff_getfilename): Make it not static.
1741 * xcoffread.c (read_xcoff_symtab): complain() not abort().
1743 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
1744 a completely gratuitous difference between xcoffread.c and coffread.c).
1746 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1748 * infrun.c (wait_for_inferior): Don't set frame for
1749 step_resume_breakpoint for IN_SIGTRAMP cases.
1751 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
1752 breakpoint.c (bpstat_what): Move step_resume from its own field of
1753 the struct bpstat_what into the main_action. Make it override
1754 other breakpoints. This is a conservative change in the sense
1755 that before the step resume breakpoint was a breakpoint.c
1756 breakpoint, hitting the step resume breakpoint overrode even
1757 calling bpstat_stop_status.
1759 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1761 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
1762 in case execution was stopped in the called function.
1763 * stack.c (print_frame_info, frame_info): If backtracing through
1764 a call dummy, handle the starting source line number on a line
1765 boundary like backtracing through sigtramp.
1766 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
1767 for call dummy frame right. Remove old test for dummy frame,
1768 it has been unused at least since gdb-3.5.
1769 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
1772 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1774 * infcmd.c (signal_command): Accept 0 as legitimate signal number.
1776 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1778 * infrun.c (signals_info), target.c (target_signal_from_name):
1779 Use ugly casts to avoid enumvar < enumvar or enumvar++.
1781 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1783 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
1784 * inflow.c (terminal_ours_1): When discussing how to deal with the
1785 tty state, make note of query() as well as readline.
1787 * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
1788 signals for which stop and print are cleared by default.
1790 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1792 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
1793 reserved fields to hold a stub unwind entry type. Fix typo.
1794 (stub_unwind_entry): New structure for raw stub unwind entries.
1795 (stub_unwind_types): The types of stubs we may encounter.
1796 (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
1797 * hppa-tdep.c (rp_saved): Use additional information provided
1798 by linker stub unwind descriptors.
1799 (frameless_function_invocation): Likewise.
1800 (frame_chain_valid): Likewise.
1801 * paread.c (compare_unwind_entries): New function for sorting
1802 unwind table entries.
1803 (read_unwind_info): Rewrite to remove dependency on host endianness.
1804 Read in data from the $UNWIND_END$ subspace which contains linker
1805 stub unwind descriptors. Merge that data into the basic unwind
1808 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
1810 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1812 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
1813 from either the symbol name or the auxent.
1814 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
1817 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
1819 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
1821 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1823 * README: Update notes for alpha port.
1825 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1827 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
1828 for operation fault, constraint fault, and type fault.

1832 * Makefile.in (init.c): Add comment explaining formatting conventions.
1834 * c-exp.y (parse_number): Assign to temporary between the right
1835 shifts, to work around a bug in the SCO compiler.
1837 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
1838 Add various files which were added to GDB recently.
1840 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
1843 * Makefile.in: Add mostlyclean target.
1845 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1849 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
1851 * main.c (show_commands): Make return type of extern
1852 history_get be HIST_ENTRY, rather than struct _hist_entry.
1853 (The latter loses with the upcoming merged readline.)
1855 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1857 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
1858 const char *, not char *.
1860 * symtab.h (struct symbol): Make section short, not unsigned short.
1862 * symtab.c (lookup_symbol): Add comment about QUIT here.
1864 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
1866 * c-exp.y (parse_number): Check for overflow regardless of range
1867 checking. Fix overflow check to use unsigned LONGEST, not
1870 * c-exp.y (parse_number): Make it so that integer constants are
1871 builtin_type_long_long if builtin_type_long isn't big enough or if
1872 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
1874 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
1875 Print our "()" first, then recurse for the target type.
1877 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1879 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
1881 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
1883 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1885 * utils.c (request_quit): Re-establish signal handler regardless
1888 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
1890 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1892 * i960-tdep.c: Include target.h.
1894 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
1896 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
1898 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1900 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
1901 changes (status -> ourstatus; declare status, etc.).
1902 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
1904 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1906 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
1908 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1910 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
1912 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1914 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
1916 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1918 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
1920 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1922 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
1923 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
1925 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
1928 Add search to target vector (#if 0'd until after 4.12):
1929 * target.h (to_search, target_search): Add.
1930 * gdbcore.h, core.c (generic_search): Add.
1931 * remote.c (remote_search): Add.
1932 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
1935 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
1936 is on, call find_pc_function rather than relying just on the minimal
1937 symbols (probably only matters for symbol readers which don't put
1938 statics in the minimal symbols, but changing this strikes me as
1939 not conservative enough).
1940 Initialize name_location in all cases.
1941 If no symbol and no msymbol, don't print anything symbolic.
1943 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
1945 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
1947 * printcmd.c (print_address_symbolic): Make it search the
1948 symtabs for variables as well as functions. Add `set print
1949 fast-symbolic-addr' and default it to fast (the old way).
1950 Print line numbers for data items as well as functions.
1952 * symtab.c (find_addr_symbol): Return the symtab and the symbol
1953 address, if a symbol is found (take two more args pointing to
1954 where to store these results).
1956 * symtab.h (find_addr_symbol): Add prototype.
1958 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1960 * objfiles.h: Fix comments to reflect the fact that the phrase
1961 "top of stack" always refers to where the pushing and popping takes
1962 place, regardless of whether it is at the highest or lowest address.
1964 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1966 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
1967 compiler generated tag names.
1968 * mdebugread.c (parse_type): Handle cross references to qualified
1970 * valops.c (value_struct_elt): Improve error message if the
1971 address of a method is requested from an object instance.
1972 * valops.c (search_struct_method): Make name_matched non-static
1973 to get it initialized correctly.
1974 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
1975 exclude segment register which are not writable on newer SCO versions.
1977 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1979 * go32-xdep.c: Remove unused function uerror.
1980 (sigsetmask): Declare return type. Declare argument (to match the
1981 way it is called). Explicitly return 0.
1983 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
1985 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
1986 partial_symbol): Shrink the storage sizes of symbols, by making
1987 enums into 1-byte bitfields when compiled __GNUC__, moving all the
1988 enums and small ints to the end of each struct to improve
1989 alignment, and switching the section number from int to unsigned
1992 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
1994 * symtab.c (find_addr_symbol): New routine that will find the nearest
1995 symbol associated with an address. It does so by exhaustive
1996 search of the symtabs, so it's slow but complete.
1998 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
2000 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
2001 to [0,0] rather than [0, end of first source file]. This avoids
2002 problems with other parts of GDB looking for linetables in the
2003 _globals_ symtab. Eliminate variables num_object_files and
2004 first_object_file_end.
2006 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2008 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
2009 (pop_frame): Restore PC2 and LR0 from dummy frames.
2010 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
2011 (setup_arbitrary_frame): Handle 3 args and set up real frames.
2012 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
2013 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
2014 (SETUP_ARBITRARY_FRAME): Define.
2016 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2018 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
2020 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2022 * remote-udi.c (udi_resume): Correct prototype.
2024 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2026 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
2027 hppa_frame_find_saved_regs.
2028 * hppa-tdep.c (dig_fp_from_stack): Delete function.
2029 (prologue_inst_adjust_sp): New function.
2030 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
2031 (skip_prologue): Completely rewrite to use unwind information.
2032 (hppa_frame_find_saved_regs): Likewise.
2034 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2036 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
2037 to convert a signal number with appropriate bounds checking.
2039 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
2041 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2043 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
2044 print a newline to end the display anyway.
2046 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
2047 coprocessor status regs) when popping a frame. This fixes
2048 float exceptions that occur after calling inferior functions.
2050 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2051 Read and write the fsr (float status register) to/from the child
2052 process along with the float regs. Remove Peter Schauer's change
2053 of May 24 '93, which has higher overhead and doesn't solve the
2054 real problem (which was that FSR wasn't being set).
2056 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
2058 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
2059 stack overflow check isn't right after the register stack
2060 adjustment instruction. Metaware R2.3u compiler moves other
2061 things in front of it. This fix isn't perfect but is what's
2064 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2066 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
2068 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
2069 character filenames.
2070 * configure.in: Change accordingly.
2072 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
2074 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
2075 _filtered io routines from these two files.
2077 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2079 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
2080 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
2081 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
2083 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
2085 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2087 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
2088 printing to gdb_stderr.
2090 * remote-udi.c (udi_kill): Don't close the connection, just set
2091 inferior_pid to zero.
2092 (udi_mourn): Call remove_breakpoints.
2094 * remote-udi.c: Remove obsolete need_artificial_traps comment.
2096 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
2098 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2100 * symtab.c (lookup_symbol): Don't try adding .c to the name.
2102 * remote-bug.c: At the start of each section, reset srec_frame
2105 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
2106 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
2107 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
2108 code which looks for those two waitkinds. Use switch statement.
2109 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
2110 CHILD_SPECIAL_WAITSTATUS.
2112 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
2113 * Move target_signal_from_host, target_signal_to_host, and
2114 store_waitstatus from inftarg.c to target.c. procfs needs them.
2115 * target.c: Include "wait.h" and <signal.h>.
2116 * target.h, infrun.c (proceed), proceed callers: Pass new code
2117 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
2118 enums being treated as unsigned and is cleaner.
2119 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
2121 * infcmd.c (signal_command), infrun.c (signals_info):
2122 Don't allow user to specify numeric equivalent of
2123 TARGET_SIGNAL_DEFAULT.
2125 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
2127 * config/alpha/alpha-netware.mt: New target support for Alpha
2129 * configure.in: Add alpha-*-netware* target.
2131 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
2133 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
2135 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2137 * target.h: Add enum target_waitkind, enum target_signal, and
2138 struct target_waitstatus. Change status argument to target_wait to
2139 be struct target_waitstatus * instead of int *.
2140 * target.h, infrun.c, all targets: Change type of signal arguments
2141 to resume(), proceed(), and target_resume() from int to enum
2143 * All targets (*_wait, *_resume): Change accordingly.
2144 * infcmd.c (program_info, signal_command), throughout infrun.c,
2145 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
2146 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
2147 signal code stuff right with the new signals would be non-trivial).
2148 * inferior.h (stop_signal): Make it enum target_signal not int.
2149 * target.c, target.h (target_signal_to_string, target_signal_to_name,
2150 target_signal_from_name): New functions.
2151 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
2152 store_waitstatus): New functions.
2153 * procfs.c (procfs_notice_signals): Use them.
2154 * i960-tdep.c (i960_fault_to_signal): New function, to replace
2156 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
2158 * objfiles.c (build_objfile_section_table): Don't abort() if
2159 objfile->sections is already set.
2161 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
2162 to match recent change to exec.c.
2166 * main.c (print_gdb_version): Change year to 1994.
2168 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
2169 * Makefile.in (NONSRC): Add ChangeLog-93.
2171 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2173 * stabsread.c (read_type): Allow defining several type numbers
2174 at once (e.g. "(1,2)=(3,4)="...).
2176 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
2178 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
2180 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2182 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
2183 to process_one_symbol.
2184 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
2185 avoid caching a bad endaddr in find_pc_partial_function.
2187 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2189 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
2191 Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2193 * infrun.c (wait_for_inferior): Do not step or step resume past
2194 the end of a one-line function we just stepped into.
2196 For older changes see ChangeLog-93
2202 version-control: never
