   9         data symbols in symbol table.
  10         * objfiles.h: Add two aux fields in struct objfile to handle
  11         multiple symbol table files situation like in os9000.
  12         * symfile.c: Change so 'symbol-file' command can handle multiple
  13         files. Also call target_link() to get relocation infos.

  15         a symbol file is requested to load.
  16         * main.c (quit_command): take out 'inferior_pid != 0' condition,
  17         because in cross mode there's no inferior pid, bit they need to
  18         be detached.

  30
  31         * target.c, target.h (target_read_string): Provide error detection to
  32         caller.  Put string in malloc'd space, so caller need not impose
  33         arbitrary limits.
  34         * solib.c (find_solib): Update to use new interface.
  35         * irix5-nat.c (find_solib): Read o_path from inferior

  45
  46         * value.h (struct value): Add modifiable field.
  47         * values.c (allocate_value, record_latest_value, value_copy): Set it.
  48         (record_latest_value): Don't mess with VALUE_LVAL of value.
  49         * valops.c (value_assign): Check it.  Reword existing error
  50         message on not_lval.
  51
  52         * mips-tdep.c (mips_step_skips_delay), config/mips/tm-mips.h
  53         (STEP_SKIPS_DELAY): Added.
  54         * infrun.c (proceed) [STEP_SKIPS_DELAY]: Check for a breakpoint in
  55         the delay slot.
  56
  57         * valprint.c (val_print_string): If errcode is set, always print
  58         an error, regardless of force_ellipsis.  In the non-EIO case,
  59         just print the error message rather than calling error().  Don't
  60         access *(bufptr-1) if bufptr points to the start of the buffer.
  61         When looking for '\0', don't increment bufptr and addr if bufptr
  62         started out already at limit.  If an error happens on fetching the
  63         first character, don't print the string.
  64
  65 Sun Feb 27 21:05:06 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  66
  67         * config/m68k/tm-apollo68b.h: Remove HAVE_68881 define; it is
  68         obsolete.

  89         target.h, remote-es.c, remote-nindy.c: Don't set baud rate if
  90         baud_rate is -1.  Remove sr_get_baud_rate and sr_set_baud_rate;
  91         just use the global variable itself.  When printing baud rate,
  92         don't print a baud rate if baud_rate is -1.
  93
  94         * coffread.c (read_coff_symtab): Pass mst_file_* to
  95         record_minimal_symbol for C_STAT symbols.  Put C_EXT and C_STAT
  96         symbols in the minimal symbols regardless of SDB_TYPE.

 103         if we hit a bp_through_sigtramp breakpoint.  Remove kludge which
 104         ignored bs->stop for a bp_step_resume breakpoint.
 105         * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
 106         which performs one (the check_sigtramp2 one) of the functions
 107         which had been handled by the step_resume_breakpoint.  For each
 108         use of the step_resume_breakpoint, make it still use the
 109         step_resume_breakpoint, use the through_sigtramp_breakpoint, or
 110         operate on both.
 111         Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
 112         When setting the frame address of the step resume breakpoint, set
 113         it to the address for frame *before* the call instruction is
 114         executed, not after.
 115
 116         * mips-tdep.c (mips_print_register): Print integers using
 117         print_scalar_formatted rather than duplicating all the
 118         CC_HAS_LONG_LONG and so on.
 119         (mips_push_dummy_frame): Use read_register_gen rather than using
 120         read_register and then putting it back in target format with
 121         store_unsigned_integer.  If registers are more than 4 bytes, give
 122         an error rather than have some registers overwrite other
 123         registers.
 124         #if 0 unused include of opcode/mips.h.
 125
 126         * symfile.h: Don't declare arguments for coff_getfilename.
 127
 128         * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

 144
 145         * tm-hppa.h (CALL_DUMMY): Add two NOP instructions to the end of
 146         the call dummy to avoid kernel bugs in HPUX, BSD, and OSF1.

 180         swap all other TYPE_CODE_FLT arguments as mips_push_arguments
 181         ensures that floats are promoted to doubles before they are pushed

 187         Fixup cache_on and flush_i_cache so that they work for both the
 188         930 and 932 processors.  Rewrite most low level funcs (uart
 189         access & cache stuff) to use new ASI access macros in sparclite.h.
 190         Also make it easy to access second serial port.

 210
 211         * Makefile.in (install): Do the sed for program_transform_name

 300
 301         * target.c (target_preopen): If target_kill doesn't remove the

 304         * coffread.c (process_coff_symbol, case C_TPDEF): Don't set name
 305         of TYPE_CODE_PTR or TYPE_CODE_FUNC types.  This parallels similar

 307
 308         * remote-udi.c (udi_files_info): If prog_name is NULL, just skip
 309         printing the program, rather than passing NULL to printf.
 310         (udi_detach): Set udi_session_id to -1 so that udi_close doesn't
 311         try to call UDIDisconnect again.  Print better message.
 312         (udi_kill): Just call UDIDisconnect ourselves, rather than doing
 313         it via udi_close.
 314         (udi_create_inferior): If udi_session_id is negative, open a new
 315         TIP rather than giving an error.
 316
 317         * config/mips/mipsm3.mh, config/i386/i386m3.mh,
 318         config/ns32k/ns32km3.mh: Define NAT_FILE.
 319         * config/nm-m3.h: Change guard from _OS_MACH3_H_ and _OS_MACH3_H
 320         (it was inconsistent and namespace-wrong) to NM_M3_H.
 321         * m3-nat.c (mach_really_wait): Change parameter name to ourstatus.
 322         (m3_open): New function.

 329
 330         * printcmd.c (printf_command):  Add missing single-letter
 331         backslash-escape sequences, and improve error message.
 332
 333 Sun Feb  6 06:55:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 334
 335         * corelow.c (solib_add_stub, core_open): Pass address of from_tty
 336         rather than trying to shove an int into a pointer and back out
 337         again.  This avoids compiler warnings.
 338
 339         * defs.h (alloca): Declare as void *, not char *, on hpux.
 340         Don't prototype it, just declare the return type.
 341
 342 Sun Feb  6 03:25:41 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 343

 345         (REGISTER_CONVERT_TO_RAW):  Add missing backslash.
 346
 347 Sat Feb  5 08:03:41 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 348
 349         * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
 350         ZERO_REGNUM, just read it as zero without talking to the board.
 351
 352         * config/i386/tm-i386aix.h (REGISTER_CONVERT_TO_RAW): Add missing
 353         backslash.
 354         * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
 355         to store_floating, not nonexistent variable len.
 356
 357         * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
 358         New functions.
 359         (mips_store_word): Change calling convention to return errors, and
 360         to provide old contents if the caller wants it.
 361         (mips_xfer_memory): Deal with errors from mips_store_word.
 362         * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT

 364
 365         * remote-mips.c (mips_create_inferior): Call warning if arguments
 366         specified, and then execute "set args" command.  Call error, not
 367         mips_error, if executable file not specified.
 368
 369         * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
 370         remote_debug.
 371
 372         * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
 373         to unsigned int.
 374
 375 Sat Feb  5 05:27:05 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 376
 377         * value.h (print_longest):  Rename "value" to "val" in prototype
 378         declaration because some compilers don't like arguments whose
 379         names are the same as types.
 380         * remote.c (remote_xfer_memory):  Cast "myaddr" to unsigned char *
 381         before passing it to remote_*_bytes.
 382
 383 Fri Feb  4 15:53:18 1994  Steve Chamberlain  (sac@cygnus.com)
 384
 385         * h8500-tdep.c (saved_pc_after_call): The size of the
 386         pc is memory model dependent. (segmented_command,

 393         (hms_open): Push the target here. (hms_before_main_loop): Not
 394         here.  (supply_val, hms_fetch_register, hms_store_register):  Cope
 395         with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
 396         * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
 397         all registers in a compact way.

 401         * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
 402         as CORE_ADDR to match definition in rs6000-tdep.c.
 403
 404 Fri Feb  4 01:14:20 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 408         definitions into the psymtab.
 409
 410 Thu Feb  3 12:38:58 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 411
 412         * m68k-stub.c: Treat mc68332 like mc68020 most places.  Provide
 413         a special exceptionSize for the 68332.
 414
 415         * remote-udi.c (udi_attach): If no arguments, print error.
 416
 417 Thu Feb  3 17:34:05 1994  Fred Fish  (fnf@cygnus.com)
 418
 419         * Makefile.in (VERSION):  Bump to 4.12.1
 420         * NEWS, README:  Update to match 4.12 release.

 423
 424         * command.c (empty_sfunc): New function.
 425         (add_set_cmd): Use it instead of not_just_help_class_command.
 426         (not_just_help_class_command): Change calling convention back to
 427         what it was before yesterday's change.
 428
 429         * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
 430         of the type if present.
 431
 432 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 433
 434         * printcmd.c (decode_format): Don't blithely set the size for
 435         an address to 'w'.  Make it 'g' or 'h', depending on TARGET_PTR_BIT.
 436
 437         * defs.h: Just typedef CORE_ADDR to bfd_vma.  Include bfd.h.
 438         If BFD64, make a LONGEST a BFD_HOST_64_BIT.
 439         * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
 440         always just check against INT_MIN and INT_MAX (this also fixes things
 441         if sizeof (long) > sizeof (int), e.g. Alpha).
 442         * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
 443         Don't define LONGEST or BUILTIN_TYPE_LONGEST.
 444         * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
 445         BUILTIN_TYPE_UNSIGNED_LONGEST.
 446         * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
 447         longest_int and longest_unsigned_int.
 448         * value.h (struct value): Just align to LONGEST, rather than worrying
 449         about CC_HAS_LONG_LONG.
 450         * valarith.c (value_binop): Figure out type ourself based on
 451         sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST.  The
 452         point is that we don't depend on CC_HAS_LONG_LONG anymore.
 453         * valprint.c (val_print_type_code_int): Just call
 454         extract_unsigned_integer directly, rather than going through
 455         unpack_long.
 456         * printcmd.c (decode_format): Remove code which would sometimes
 457         change 'g' size to 'w' for integers.  print_scalar_formatted handles
 458         printing huge integers well enough, thank you.
 459
 460         * command.c (add_set_cmd, not_just_help_class_command): Change
 461         to make this the sfunc, not cfunc, since that is how we call it.
 462         * command.h: Comment difference between sfunc and cfunc.
 463         * demangle.c (set_demangling_command): Add third arg since that
 464         is how it is called.
 465         (_initialize_demangler): Use sfunc, not cfunc, for
 466         set_demangling_command, since that is how it is called.
 467         Remove show_demangling_command; it has no effect.
 468
 469         * command.c (shell_escape): Report errors correctly (with error
 470         message from strerror).
 471
 472 Wed Feb  2 14:35:41 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 473
 474         * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
 475         x_scnlen.l rather than x_scnlen to match corresponding change in
 476         coff/internal.h.
 477
 478 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 479
 480         * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
 481         Change comments regarding TYPE_CODE_BOOL.
 482         * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
 483         regardless of the language.
 484         (value_true): Just call value_logical_not regardless of language.
 485         * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
 486         Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
 487         * language.h: Improve comment for la_builtin_type_vector.
 488         * m2-lang.c (_initialize_m2_language): Don't add any fields to
 489         builtin_type_m2_bool.
 490
 491 Tue Feb  1 17:13:32 1994  Kevin Buettner (kev@cujo.geg.mot.com)
 492
 493         * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
 494         Define IN_SIGTRAMP and backtrace correctly through signal handlers.

 503         * target.h (target_wait): Add comment about calling
 504         return_to_top_level.
 505
 506 Tue Feb  1 12:21:00 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 507
 508         * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
 509         additional arguments.
 510         * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
 511
 512 Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)

 515
 516 Mon Jan 31 12:12:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 517
 518         * mips-tdep.c: Remove code which sets saved_regs from
 519         init_extra_frame_info and put it in new function mips_find_saved_regs.
 520         (READ_FRAME_REG): Remove macro and replace uses with the expansion.
 521         * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
 522         check if it is NULL and call mips_find_saved_regs if so.
 523
 524         * remote-mips.c: Use unfiltered, not filtered, output most places.
 525
 526         * blockframe.c (get_prev_frame_info): Detect and stop an infinite
 527         backtrace.  Revise comments.
 528
 529 Mon Jan 31 09:40:33 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 530
 531         * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
 532         alpha and irix. The _sigtramp case has to be handled properly
 533         in the tdep files if we have no ecoff debugging info.
 534         * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
 535         mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
 536         without PC_REGNUM kludge.
 537         * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
 538         Clean up handling of mips sigtramp frames, improve comments.
 539
 540 Sat Jan 29 23:25:57 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 541
 542         * paread.c (read_unwind_info): Fix typo.
 543
 544         * paread.c (pa_symtab_read): Update the "check_strange_names"
 545         filter to match GCC's current output.  Filter out section symbols
 546         (which the HP linker sometimes puts in the wrong place).
 547
 548 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 549
 550         * serial.h (SERIAL_SET_TTY_STATE): Comment return value.

 553
 554         * Makefile.in: Remove all references to sparcly-nat.c.
 555
 556         * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
 557         remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
 558         duplicating serial.h and target.h.
 559
 560         * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
 561         are not used anywhere (a 5 Oct 1993 change removed the uses).
 562
 563         * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
 564         * config/m68k/es1800.mt: Add comment.
 565         * remote-es.c: Extensive changes to update to current conventions.
 566
 567         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
 568         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
 569         to achieve the desired timeout.
 570         * serial.h (serial_t): Add field timeout_remaining.
 571
 572 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 573
 574         * c-exp.y (yylex): Reenable nested type code.
 575
 576 Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

 584         * config/m68k/tm-monitor.h: Changes to bring this into accordance
 585         with the old tm-m68k-em.h:
 586         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
 587         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
 588         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
 589         Add FIXME regarding GET_LONGJMP_TARGET.
 590
 591         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
 592         * infptrace.c (kill_inferior): Add comments.
 593         * main.c (quit_command): Call target_close after we kill or
 594         detach.
 595         * remote-udi.c (udi_close): Don't error() if QUITTING.
 596
 597 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
 598
 599         * configure.in: Make m68k-coff and aout add monitor support in
 600         addition to the standard serial support.

 612
 613 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 614
 615         * i386-stub.c: Add ".text" right before "mem_fault:".
 616
 617         * main.c (baud_rate): Add FIXME comment about printing -1 value.
 618
 619         * remote-utils.c (usage): Fix message to be accurate and conform
 620         more closely to normal conventions.
 621
 622         * remote-utils.c (gr_files_info): Have the exec_bfd test control
 623         whether to show information about exec_bfd, and not control whether
 624         to show information about device and speed.
 625
 626         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
 627         usage message, don't dump core.
 628
 629         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
 630         for variable size array.
 631         (bug_fetch_register, bug_store_register): Rename "value" to
 632         "fpreg_buf" because some compilers don't like variables whose
 633         names are the same as types.
 634         (bug_store_register): Use a cast when converting char * to
 635         unsigned char *.
 636
 637         * symmisc.c (maintenance_print_symbols): Don't refer to the name
 638         of the command in error message (the text was referring to the old
 639         name of the command).
 640
 641         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
 642
 643         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
 644         full details on structure elements without names.  This partially
 645         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
 646         of those changes was accidental.
 647
 648         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
 649         defined, make it an error to specify a single argument which is not
 650         a frame number.
 651
 652         * Makefile.in (version.c), main.c (print_gdb_version): Use
 653         host_alias and target_alias, not host_canonical and
 654         target_canonical, to print configuration.
 655
 656 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 657
 658         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
 659         of builtin_type_long.  It is necessary to get a type which is
 660         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
 661
 662         Fix many sins which will come up in 32 bit x 64 bit GDB, and
 663         various miscellaneous things discovered in the process:
 664         * printcmd.c, defs.h (print_address_numeric): New function.
 665         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 666         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 667         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 668         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 669         Use it.
 670         * utils.c, defs.h (gdb_print_address): New function.
 671         * expprint (dump_expression), gdbtypes.h: Use it.
 672         * breakpoint.c (describe_other_breakpoints),
 673         symmisc.c (dump_symtab, print_symbol):
 674         Use filtered not unfiltered I/O.
 675         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 676         just run gdb under a debugger for this (and it had problems with
 677         printing addresses, how to print b->shadow, etc.).
 678         * buildsym.c (make_blockvector), core.c (memory_error),
 679         exec.c (print_section_info), maint.c (print_section_table),
 680         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 681         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 682         Add comments saying code is broken.  Marked with "FIXME-32x64".
 683         * dbxread.c (process_one_symbol), partial-stab.h (default),
 684         remote-vx.c (vx_run_files_info):
 685         Don't cast int being passed to local_hex_string.
 686         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 687         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 688         only being a long.
 689         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 690         and LOC_LOCAL.
 691         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 692         * source.c: Include <sys/types.h> regardless of USG.
 693
 694 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 695
 696         * valops.c (value_assign):  Set `type' after coercing toval.
 697         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 698         Use extract_unsigned_integer to get the address of a reference.
 699
 700 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 701
 702         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 703         AIX can use ? instead of \ for continuation.  Deal with it.
 704
 705         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 706         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 707         the HP compiler in ANSI mode doesn't like.
 708
 709         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 710         based on USG, rather than defining HAVE_SIGSETMASK to an
 711         expression containing defined.  Having a macro used in #if expand
 712         to an expression containing "defined" is undefined according to
 713         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 714         it to.
 715
 716 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 717
 718         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 719         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 720
 721 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 722
 723         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 724         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 725
 726 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 727
 728         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 729         passing them to print_387_status.
 730         (print_387_status): Don't subtract top from 7 before using it.
 731         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 732         from 7; the above explains it.
 733
 734 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 735
 736         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 737         pointer value when fixing up the frame at the start of a function.
 738
 739 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 740
 741         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 742         Sparc from the stack.
 743
 744 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 745
 746         * remote-mips.c (mips_initialize): Clear mips_initializing via
 747         cleanup chain, not directly.
 748
 749         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 750         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 751         munging the timeout due to the limited range of c_cc[VTIME].
 752
 753         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 754         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
 755         m3-nat.c (m3_create_inferior): Pass it.
 756         * procfs.c: Remove ptrace function.  It was declared in a way which
 757         conflicted with the prototype in unistd.h on Solaris.
 758
 759 Sat Jan 22 01:37:40 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 760
 761         * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
 762         in the sigcontext if it is a signal trampoline frame.
 763         * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
 764         Define for Solaris2.
 765
 766 Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)
 767
 768         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 769         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 770         tm-sparc.h so they can be overridden if necessary.
 771
 772 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 773
 774         * lynx-nat.c:  Add Sparc support.
 775         * sparcly-nat.c:  Remove.  It's useless.
 776         * config/sparc/nm-sparclynx.h:  Rewrite.
 777         * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
 778         with lynx-nat.o
 779         * config/sparc/tm-sparclynx.h:  Rewrite.
 780
 781 Fri Jan 21 19:08:48 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 782
 783         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 784         directory.  Old code was discarded, since the new opcode table has
 785         a different format.
 786
 787 Fri Jan 21 14:28:30 1994  Fred Fish  (fnf@cygnus.com)
 788
 789         * Makefile.in (realclean):  Remove info files per make-stds.texi.
 790
 791 Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 792
 793         * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
 794         if N_SO_ADDRESS_MAYBE_MISSING is defined.
 795         * config/sparc/tm-sun4sol2.h: Define it.
 796

 798
 799         * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
 800         if we did not find a symbol.
 801
 802 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 803
 804         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 805         is not defined.
 806
 807         * hppab-nat.c (call_ptrace): Delete redundant function.
 808         (kill_inferior, attach, detach, child_resume): Likewise.
 809         (child_xfer_memory): Likewise.
 810
 811         * hppah-nat.c (call_ptrace): Delete redundant function.
 812         (kill_inferior, attach, detach, child_resume): Likewise.
 813
 814         * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
 815
 816         * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
 817
 818         * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
 819
 820         * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
 821         (CHILD_XFER_MEMORY): Define.
 822         (PT_*): Define so that generic infptrace.c code can be used.
 823
 824 Fri Jan 21 09:23:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 825
 826         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 827         struct section_offsets *, not a (nonexistent) struct section_offset *.
 828
 829         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 830         internal_xcoff_symtab, not an array of one of them.  Change lots of
 831         "main_aux" to "&main_aux" and so on.
 832
 833         * coffread.c, xcoffread.c: Include <coff/internal.h>
 834         before "symfile.h".
 835
 836 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 837
 838         * coffread.c (coff_getfilename): Make it not static.
 839
 840         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 841
 842         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 843         a completely gratuitous difference between xcoffread.c and coffread.c).
 844
 845 Wed Jan 19 15:09:44 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 846
 847         * infrun.c (wait_for_inferior): Don't set frame for
 848         step_resume_breakpoint for IN_SIGTRAMP cases.
 849
 850         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 851         breakpoint.c (bpstat_what): Move step_resume from its own field of
 852         the struct bpstat_what into the main_action.  Make it override
 853         other breakpoints.  This is a conservative change in the sense
 854         that before the step resume breakpoint was a breakpoint.c
 855         breakpoint, hitting the step resume breakpoint overrode even
 856         calling bpstat_stop_status.
 857
 858 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 859
 860         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
 861         in case execution was stopped in the called function.
 862         * stack.c (print_frame_info, frame_info):  If backtracing through
 863         a call dummy, handle the starting source line number on a line
 864         boundary like backtracing through sigtramp.
 865         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 866         for call dummy frame right.  Remove old test for dummy frame,
 867         it has been unused at least since gdb-3.5.
 868         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 869         of the dummy frame.

 872
 873         * infcmd.c (signal_command): Accept 0 as legitimate signal number.
 874
 875 Tue Jan 18 14:09:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 876
 877         * infrun.c (signals_info), target.c (target_signal_from_name):
 878         Use ugly casts to avoid enumvar < enumvar or enumvar++.
 879
 880 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 881
 882         * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
 883         * inflow.c (terminal_ours_1): When discussing how to deal with the
 884         tty state, make note of query() as well as readline.
 885
 886         * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
 887         signals for which stop and print are cleared by default.
 888
 889 Mon Jan 17 20:00:51 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 890
 891         * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
 892         reserved fields to hold a stub unwind entry type.  Fix typo.
 893         (stub_unwind_entry): New structure for raw stub unwind entries.
 894         (stub_unwind_types): The types of stubs we may encounter.
 895         (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
 896         * hppa-tdep.c (rp_saved): Use additional information provided
 897         by linker stub unwind descriptors.
 898         (frameless_function_invocation): Likewise.
 899         (frame_chain_valid): Likewise.
 900         * paread.c (compare_unwind_entries): New function for sorting
 901         unwind table entries.
 902         (read_unwind_info): Rewrite to remove dependency on host endianness.
 903         Read in data from the $UNWIND_END$ subspace which contains linker
 904         stub unwind descriptors.  Merge that data into the basic unwind
 905         table.
 906
 907         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 908
 909 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 910
 911         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
 912         from either the symbol name or the auxent.
 913         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 914         no longer static.

 930
 931         * Makefile.in (init.c): Add comment explaining formatting conventions.
 932
 933         * c-exp.y (parse_number): Assign to temporary between the right
 934         shifts, to work around a bug in the SCO compiler.
 935
 936         * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
 937         Add various files which were added to GDB recently.
 938
 939         * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
 940         within_function.
 941
 942         * Makefile.in: Add mostlyclean target.

 948 Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 949
 950         * main.c (show_commands):  Make return type of extern
 951         history_get be HIST_ENTRY, rather than struct _hist_entry.
 952         (The latter loses with the upcoming merged readline.)
 953
 954 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 955
 956         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
 957         const char *, not char *.
 958
 959         * symtab.h (struct symbol): Make section short, not unsigned short.

 961         * symtab.c (lookup_symbol): Add comment about QUIT here.
 962
 963         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 964
 965         * c-exp.y (parse_number): Check for overflow regardless of range
 966         checking.  Fix overflow check to use unsigned LONGEST, not
 967         unsigned int.
 968
 969         * c-exp.y (parse_number): Make it so that integer constants are
 970         builtin_type_long_long if builtin_type_long isn't big enough or if
 971         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 972
 973         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 974         Print our "()" first, then recurse for the target type.
 975
 976 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 977
 978         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 979
 980         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 981
 982 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 983
 984         * utils.c (request_quit): Re-establish signal handler regardless
 985         of USG.
 986
 987         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 988
 989 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 990
 991         * i960-tdep.c: Include target.h.
 992
 993 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 994
 995         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 996
 997 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 998
 999         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
1000         changes (status -> ourstatus; declare status, etc.).
1001         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
1002
1003 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1004

1008
1009         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
1010
1011 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1012
1013         * config/i386/xm-linux.h: Define HAVE_TERMIOS.

1016
1017         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
1018
1019 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1020
1021         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
1022         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
1023
1024         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
1025         writing it.
1026
1027         Add search to target vector (#if 0'd until after 4.12):
1028         * target.h (to_search, target_search): Add.
1029         * gdbcore.h, core.c (generic_search): Add.
1030         * remote.c (remote_search): Add.
1031         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
1032         tag.
1033
1034         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
1035         is on, call find_pc_function rather than relying just on the minimal
1036         symbols (probably only matters for symbol readers which don't put
1037         statics in the minimal symbols, but changing this strikes me as
1038         not conservative enough).
1039         Initialize name_location in all cases.
1040         If no symbol and no msymbol, don't print anything symbolic.
1041
1042         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
1043
1044 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
1045
1046         * printcmd.c (print_address_symbolic):  Make it search the
1047         symtabs for variables as well as functions.  Add `set print
1048         fast-symbolic-addr' and default it to fast (the old way).
1049         Print line numbers for data items as well as functions.
1050
1051         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
1052         address, if a symbol is found (take two more args pointing to
1053         where to store these results).
1054
1055         * symtab.h (find_addr_symbol):  Add prototype.
1056
1057 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1058
1059         * objfiles.h: Fix comments to reflect the fact that the phrase
1060         "top of stack" always refers to where the pushing and popping takes
1061         place, regardless of whether it is at the highest or lowest address.
1062
1063 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
1064
1065         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
1066         compiler generated tag names.
1067         * mdebugread.c (parse_type):  Handle cross references to qualified
1068         aggregate types.
1069         * valops.c (value_struct_elt):  Improve error message if the
1070         address of a method is requested from an object instance.
1071         * valops.c (search_struct_method):  Make name_matched non-static
1072         to get it initialized correctly.
1073         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
1074         exclude segment register which are not writable on newer SCO versions.
1075
1076 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1077
1078         * go32-xdep.c: Remove unused function uerror.
1079         (sigsetmask): Declare return type.  Declare argument (to match the
1080         way it is called).  Explicitly return 0.
1081
1082 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
1083
1084         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
1085         partial_symbol):  Shrink the storage sizes of symbols, by making
1086         enums into 1-byte bitfields when compiled __GNUC__, moving all the
1087         enums and small ints to the end of each struct to improve
1088         alignment, and switching the section number from int to unsigned
1089         short.
1090
1091 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
1092
1093         * symtab.c (find_addr_symbol):  New routine that will find the nearest
1094         symbol associated with an address.  It does so by exhaustive
1095         search of the symtabs, so it's slow but complete.
1096
1097 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
1098
1099         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
1100         to [0,0] rather than [0, end of first source file].  This avoids
1101         problems with other parts of GDB looking for linetables in the
1102         _globals_ symtab.  Eliminate variables num_object_files and
1103         first_object_file_end.
1104
1105 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
1106
1107         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
1108         (pop_frame):  Restore PC2 and LR0 from dummy frames.
1109         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
1110         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
1111         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
1112         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
1113         (SETUP_ARBITRARY_FRAME):  Define.
1114
1115 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
1116
1117         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
1118
1119 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
1120
1121         * remote-udi.c (udi_resume): Correct prototype.
1122
1123 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
1124
1125         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
1126         hppa_frame_find_saved_regs.
1127         * hppa-tdep.c (dig_fp_from_stack): Delete function.
1128         (prologue_inst_adjust_sp): New function.
1129         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
1130         (skip_prologue): Completely rewrite to use unwind information.
1131         (hppa_frame_find_saved_regs): Likewise.
1132
1133 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
1134
1135         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
1136         to convert a signal number with appropriate bounds checking.
1137
1138         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
1139
1140 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
1141
1142         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
1143         print a newline to end the display anyway.
1144
1145         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
1146         coprocessor status regs) when popping a frame.  This fixes
1147         float exceptions that occur after calling inferior functions.
1148
1149         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
1150         Read and write the fsr (float status register) to/from the child
1151         process along with the float regs.  Remove Peter Schauer's change
1152         of May 24 '93, which has higher overhead and doesn't solve the
1153         real problem (which was that FSR wasn't being set).
1154
1155 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
1156
1157         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
1158         stack overflow check isn't right after the register stack
1159         adjustment instruction.  Metaware R2.3u compiler moves other
1160         things in front of it.  This fix isn't perfect but is what's
1161         running.
1162
1163 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
1164
1165         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
1166
1167         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
1168         character filenames.
1169         * configure.in: Change accordingly.
1170
1171 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
1172
1173         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
1174         _filtered io routines from these two files.
1175
1176 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

1179         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
1180         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
1181         DEC c89.
1182         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.

1184 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1185
1186         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
1187         printing to gdb_stderr.
1188
1189         * remote-udi.c (udi_kill): Don't close the connection, just set
1190         inferior_pid to zero.
1191         (udi_mourn): Call remove_breakpoints.
1192
1193         * remote-udi.c: Remove obsolete need_artificial_traps comment.
1194
1195         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
1196
1197 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
1198
1199         * symtab.c (lookup_symbol): Don't try adding .c to the name.
1200
1201         * remote-bug.c: At the start of each section, reset srec_frame
1202         back to 160.
1203
1204         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
1205         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
1206         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
1207         code which looks for those two waitkinds.  Use switch statement.
1208         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
1209         CHILD_SPECIAL_WAITSTATUS.
1210
1211         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
1212         * Move target_signal_from_host, target_signal_to_host, and
1213         store_waitstatus from inftarg.c to target.c.  procfs needs them.
1214         * target.c: Include "wait.h" and <signal.h>.
1215         * target.h, infrun.c (proceed), proceed callers: Pass new code
1216         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
1217         enums being treated as unsigned and is cleaner.
1218         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
1219         TARGET_SIGNAL_0.
1220         * infcmd.c (signal_command), infrun.c (signals_info):
1221         Don't allow user to specify numeric equivalent of
1222         TARGET_SIGNAL_DEFAULT.
1223

1235
1236         * target.h: Add enum target_waitkind, enum target_signal, and
1237         struct target_waitstatus.  Change status argument to target_wait to
1238         be struct target_waitstatus * instead of int *.
1239         * target.h, infrun.c, all targets: Change type of signal arguments
1240         to resume(), proceed(), and target_resume() from int to enum
1241         target_signal.
1242         * All targets (*_wait, *_resume): Change accordingly.
1243         * infcmd.c (program_info, signal_command), throughout infrun.c,
1244         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
1245         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
1246         signal code stuff right with the new signals would be non-trivial).
1247         * inferior.h (stop_signal): Make it enum target_signal not int.
1248         * target.c, target.h (target_signal_to_string, target_signal_to_name,
1249         target_signal_from_name): New functions.
1250         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
1251         store_waitstatus): New functions.
1252         * procfs.c (procfs_notice_signals): Use them.
1253         * i960-tdep.c (i960_fault_to_signal): New function, to replace
1254         print_fault.
1255         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
1256
1257         * objfiles.c (build_objfile_section_table): Don't abort() if
1258         objfile->sections is already set.
1259
1260         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
1261         to match recent change to exec.c.
1262
1263         * Version 4.11.3.
1264
1265         * main.c (print_gdb_version): Change year to 1994.
1266
1267         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
1268         * Makefile.in (NONSRC): Add ChangeLog-93.

1270 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
1271
1272         * stabsread.c (read_type): Allow defining several type numbers
1273         at once (e.g. "(1,2)=(3,4)="...).
1274

1283         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
