   1 Fri Feb  4 07:41:13 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
   2
   3         * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
   4         as CORE_ADDR to match definition in rs6000-tdep.c.
   5
   6 Fri Feb  4 01:14:20 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
   7
   8         * dwarfread.c (process_dies):  Skip nested TAG_compile_unit DIEs.
   9         * dwarfread.c (add_partial_symbol):  Do not enter opaque aggregate
  10         definitions into the psymtab.
  11
  12 Thu Feb  3 12:38:58 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  13
  14         * m68k-stub.c: Treat mc68332 like mc68020 most places.  Provide
  15         a special exceptionSize for the 68332.
  16
  17         * remote-udi.c (udi_attach): If no arguments, print error.
  18
  19 Thu Feb  3 17:34:05 1994  Fred Fish  (fnf@cygnus.com)
  20
  21         * Makefile.in (VERSION):  Bump to 4.12.1
  22         * NEWS, README:  Update to match 4.12 release.
  23
  24 Thu Feb  3 12:38:58 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  25
  26         * command.c (empty_sfunc): New function.
  27         (add_set_cmd): Use it instead of not_just_help_class_command.
  28         (not_just_help_class_command): Change calling convention back to
  29         what it was before yesterday's change.
  30
  31         * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
  32         of the type if present.
  33
  34 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  35
  36         * printcmd.c (decode_format): Don't blithely set the size for
  37         an address to 'w'.  Make it 'g' or 'h', depending on TARGET_PTR_BIT.
  38
  39         * defs.h: Just typedef CORE_ADDR to bfd_vma.  Include bfd.h.
  40         If BFD64, make a LONGEST a BFD_HOST_64_BIT.
  41         * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
  42         always just check against INT_MIN and INT_MAX (this also fixes things
  43         if sizeof (long) > sizeof (int), e.g. Alpha).
  44         * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
  45         Don't define LONGEST or BUILTIN_TYPE_LONGEST.
  46         * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
  47         BUILTIN_TYPE_UNSIGNED_LONGEST.
  48         * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
  49         longest_int and longest_unsigned_int.
  50         * value.h (struct value): Just align to LONGEST, rather than worrying
  51         about CC_HAS_LONG_LONG.
  52         * valarith.c (value_binop): Figure out type ourself based on
  53         sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST.  The
  54         point is that we don't depend on CC_HAS_LONG_LONG anymore.
  55         * valprint.c (val_print_type_code_int): Just call
  56         extract_unsigned_integer directly, rather than going through
  57         unpack_long.
  58         * printcmd.c (decode_format): Remove code which would sometimes
  59         change 'g' size to 'w' for integers.  print_scalar_formatted handles
  60         printing huge integers well enough, thank you.
  61
  62         * command.c (add_set_cmd, not_just_help_class_command): Change
  63         to make this the sfunc, not cfunc, since that is how we call it.
  64         * command.h: Comment difference between sfunc and cfunc.
  65         * demangle.c (set_demangling_command): Add third arg since that
  66         is how it is called.
  67         (_initialize_demangler): Use sfunc, not cfunc, for
  68         set_demangling_command, since that is how it is called.
  69         Remove show_demangling_command; it has no effect.
  70
  71         * command.c (shell_escape): Report errors correctly (with error
  72         message from strerror).
  73
  74 Wed Feb  2 14:35:41 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  75
  76         * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
  77         x_scnlen.l rather than x_scnlen to match corresponding change in
  78         coff/internal.h.
  79
  80 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  81
  82         * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
  83         Change comments regarding TYPE_CODE_BOOL.
  84         * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
  85         regardless of the language.
  86         (value_true): Just call value_logical_not regardless of language.
  87         * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
  88         Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
  89         * language.h: Improve comment for la_builtin_type_vector.
  90         * m2-lang.c (_initialize_m2_language): Don't add any fields to
  91         builtin_type_m2_bool.
  92
  93 Tue Feb  1 17:13:32 1994  Kevin Buettner (kev@cujo.geg.mot.com)
  94
  95         * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
  96         Define IN_SIGTRAMP and backtrace correctly through signal handlers.
  97
  98 Tue Feb  1 22:13:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  99
 100         * procfs.c (wait_fd):  Handle EINTR error return from PIOCWSTOP ioctl
 101         by restarting the ioctl.
 102
 103 Tue Feb  1 16:16:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 104
 105         * target.h (target_wait): Add comment about calling
 106         return_to_top_level.
 107
 108 Tue Feb  1 12:21:00 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 109
 110         * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
 111         additional arguments.
 112         * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
 113
 114 Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)
 115
 116         * sparc-stub.c:  Remove unnecessary #include of memory.h.
 117
 118 Mon Jan 31 12:12:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 119
 120         * mips-tdep.c: Remove code which sets saved_regs from
 121         init_extra_frame_info and put it in new function mips_find_saved_regs.
 122         (READ_FRAME_REG): Remove macro and replace uses with the expansion.
 123         * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
 124         check if it is NULL and call mips_find_saved_regs if so.
 125
 126         * remote-mips.c: Use unfiltered, not filtered, output most places.
 127
 128         * blockframe.c (get_prev_frame_info): Detect and stop an infinite
 129         backtrace.  Revise comments.
 130
 131 Mon Jan 31 09:40:33 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 132
 133         * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
 134         alpha and irix. The _sigtramp case has to be handled properly
 135         in the tdep files if we have no ecoff debugging info.
 136         * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
 137         mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
 138         without PC_REGNUM kludge.
 139         * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
 140         Clean up handling of mips sigtramp frames, improve comments.
 141
 142 Sat Jan 29 23:25:57 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 143
 144         * paread.c (read_unwind_info): Fix typo.
 145
 146         * paread.c (pa_symtab_read): Update the "check_strange_names"
 147         filter to match GCC's current output.  Filter out section symbols
 148         (which the HP linker sometimes puts in the wrong place).
 149
 150 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 151
 152         * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
 153
 154         * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
 155
 156         * Makefile.in: Remove all references to sparcly-nat.c.
 157
 158         * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
 159         remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
 160         duplicating serial.h and target.h.
 161
 162         * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
 163         are not used anywhere (a 5 Oct 1993 change removed the uses).
 164
 165         * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
 166         * config/m68k/es1800.mt: Add comment.
 167         * remote-es.c: Extensive changes to update to current conventions.
 168
 169         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
 170         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
 171         to achieve the desired timeout.
 172         * serial.h (serial_t): Add field timeout_remaining.
 173
 174 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 175
 176         * c-exp.y (yylex): Reenable nested type code.
 177
 178 Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 179
 180         * a29k-tdep.c (examine_tag): Add comment regarding argcount.
 181
 182         * remote-mips.c (mips_ops): Fix docstring.
 183
 184         * remote-bug.c (bug_ops): Remove spurious newline from docstring.
 185
 186         * config/m68k/tm-monitor.h: Changes to bring this into accordance
 187         with the old tm-m68k-em.h:
 188         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
 189         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
 190         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
 191         Add FIXME regarding GET_LONGJMP_TARGET.
 192
 193         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
 194         * infptrace.c (kill_inferior): Add comments.
 195         * main.c (quit_command): Call target_close after we kill or
 196         detach.
 197         * remote-udi.c (udi_close): Don't error() if QUITTING.
 198
 199 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
 200
 201         * configure.in: Make m68k-coff and aout add monitor support in
 202         addition to the standard serial support.
 203
 204 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 205
 206         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
 207         index indexNil.
 208
 209 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 210
 211         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
 212         * elfread.c (record_minimal_symbol_and_info),
 213         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
 214
 215 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 216
 217         * i386-stub.c: Add ".text" right before "mem_fault:".
 218
 219         * main.c (baud_rate): Add FIXME comment about printing -1 value.
 220
 221         * remote-utils.c (usage): Fix message to be accurate and conform
 222         more closely to normal conventions.
 223
 224         * remote-utils.c (gr_files_info): Have the exec_bfd test control
 225         whether to show information about exec_bfd, and not control whether
 226         to show information about device and speed.
 227
 228         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
 229         usage message, don't dump core.
 230
 231         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
 232         for variable size array.
 233         (bug_fetch_register, bug_store_register): Rename "value" to
 234         "fpreg_buf" because some compilers don't like variables whose
 235         names are the same as types.
 236         (bug_store_register): Use a cast when converting char * to
 237         unsigned char *.
 238
 239         * symmisc.c (maintenance_print_symbols): Don't refer to the name
 240         of the command in error message (the text was referring to the old
 241         name of the command).
 242
 243         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
 244
 245         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
 246         full details on structure elements without names.  This partially
 247         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
 248         of those changes was accidental.
 249
 250         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
 251         defined, make it an error to specify a single argument which is not
 252         a frame number.
 253
 254         * Makefile.in (version.c), main.c (print_gdb_version): Use
 255         host_alias and target_alias, not host_canonical and
 256         target_canonical, to print configuration.
 257
 258 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 259
 260         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
 261         of builtin_type_long.  It is necessary to get a type which is
 262         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
 263
 264         Fix many sins which will come up in 32 bit x 64 bit GDB, and
 265         various miscellaneous things discovered in the process:
 266         * printcmd.c, defs.h (print_address_numeric): New function.
 267         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 268         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 269         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 270         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 271         Use it.
 272         * utils.c, defs.h (gdb_print_address): New function.
 273         * expprint (dump_expression), gdbtypes.h: Use it.
 274         * breakpoint.c (describe_other_breakpoints),
 275         symmisc.c (dump_symtab, print_symbol):
 276         Use filtered not unfiltered I/O.
 277         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 278         just run gdb under a debugger for this (and it had problems with
 279         printing addresses, how to print b->shadow, etc.).
 280         * buildsym.c (make_blockvector), core.c (memory_error),
 281         exec.c (print_section_info), maint.c (print_section_table),
 282         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 283         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 284         Add comments saying code is broken.  Marked with "FIXME-32x64".
 285         * dbxread.c (process_one_symbol), partial-stab.h (default),
 286         remote-vx.c (vx_run_files_info):
 287         Don't cast int being passed to local_hex_string.
 288         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 289         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 290         only being a long.
 291         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 292         and LOC_LOCAL.
 293         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 294         * source.c: Include <sys/types.h> regardless of USG.
 295
 296 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 297
 298         * valops.c (value_assign):  Set `type' after coercing toval.
 299         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 300         Use extract_unsigned_integer to get the address of a reference.
 301
 302 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 303
 304         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 305         AIX can use ? instead of \ for continuation.  Deal with it.
 306
 307         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 308         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 309         the HP compiler in ANSI mode doesn't like.
 310
 311         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 312         based on USG, rather than defining HAVE_SIGSETMASK to an
 313         expression containing defined.  Having a macro used in #if expand
 314         to an expression containing "defined" is undefined according to
 315         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 316         it to.
 317
 318 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 319
 320         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 321         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 322
 323 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)

 331         passing them to print_387_status.

 333         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted

 352         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 353         munging the timeout due to the limited range of c_cc[VTIME].

 375
 376         * lynx-nat.c:  Add Sparc support.

 431         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 432         internal_xcoff_symtab, not an array of one of them.  Change lots of

 434
 435         * coffread.c, xcoffread.c: Include <coff/internal.h>
 436         before "symfile.h".

 445         a completely gratuitous difference between xcoffread.c and coffread.c).

 453         breakpoint.c (bpstat_what): Move step_resume from its own field of
 454         the struct bpstat_what into the main_action.  Make it override
 455         other breakpoints.  This is a conservative change in the sense
 456         that before the step resume breakpoint was a breakpoint.c
 457         breakpoint, hitting the step resume breakpoint overrode even
 458         calling bpstat_stop_status.

 466         boundary like backtracing through sigtramp.
 467         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 468         for call dummy frame right.  Remove old test for dummy frame,
 469         it has been unused at least since gdb-3.5.
 470         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 471         of the dummy frame.

 504         (read_unwind_info): Rewrite to remove dependency on host endianness.
 505         Read in data from the $UNWIND_END$ subspace which contains linker
 506         stub unwind descriptors.  Merge that data into the basic unwind
 507         table.
 508
 509         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.

 552         * main.c (show_commands):  Make return type of extern
 553         history_get be HIST_ENTRY, rather than struct _hist_entry.

 572         builtin_type_long_long if builtin_type_long isn't big enough or if
 573         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.

 575         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 576         Print our "()" first, then recurse for the target type.

 634         tag.
 635
 636         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 637         is on, call find_pc_function rather than relying just on the minimal
 638         symbols (probably only matters for symbol readers which don't put
 639         statics in the minimal symbols, but changing this strikes me as
 640         not conservative enough).
 641         Initialize name_location in all cases.
 642         If no symbol and no msymbol, don't print anything symbolic.
 643
 644         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.

 647
 648         * printcmd.c (print_address_symbolic):  Make it search the
 649         symtabs for variables as well as functions.  Add `set print

 651         Print line numbers for data items as well as functions.
 652
 653         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 654         address, if a symbol is found (take two more args pointing to

 672         address of a method is requested from an object instance.
 673         * valops.c (search_struct_method):  Make name_matched non-static
 674         to get it initialized correctly.
 675         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 676         exclude segment register which are not writable on newer SCO versions.
 677
 678 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 679
 680         * go32-xdep.c: Remove unused function uerror.
 681         (sigsetmask): Declare return type.  Declare argument (to match the
 682         way it is called).  Explicitly return 0.
 683
 684 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 685
 686         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 687         partial_symbol):  Shrink the storage sizes of symbols, by making
 688         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 689         enums and small ints to the end of each struct to improve
 690         alignment, and switching the section number from int to unsigned
 691         short.
 692
 693 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 694
 695         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 696         symbol associated with an address.  It does so by exhaustive
 697         search of the symtabs, so it's slow but complete.
 698
 699 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 700
 701         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 702         to [0,0] rather than [0, end of first source file].  This avoids
 703         problems with other parts of GDB looking for linetables in the
 704         _globals_ symtab.  Eliminate variables num_object_files and
 705         first_object_file_end.
 706
 707 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 708
 709         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 710         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 711         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 712         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 713         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 714         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 715         (SETUP_ARBITRARY_FRAME):  Define.
 716
 717 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 718
 719         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 720
 721 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 722
 723         * remote-udi.c (udi_resume): Correct prototype.
 724
 725 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 726
 727         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 728         hppa_frame_find_saved_regs.
 729         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 730         (prologue_inst_adjust_sp): New function.
 731         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 732         (skip_prologue): Completely rewrite to use unwind information.
 733         (hppa_frame_find_saved_regs): Likewise.
 734
 735 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 736
 737         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 738         to convert a signal number with appropriate bounds checking.
 739
 740         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 741
 742 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 743
 744         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 745         print a newline to end the display anyway.
 746
 747         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 748         coprocessor status regs) when popping a frame.  This fixes
 749         float exceptions that occur after calling inferior functions.
 750
 751         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 752         Read and write the fsr (float status register) to/from the child
 753         process along with the float regs.  Remove Peter Schauer's change
 754         of May 24 '93, which has higher overhead and doesn't solve the
 755         real problem (which was that FSR wasn't being set).
 756
 757 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 758
 759         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 760         stack overflow check isn't right after the register stack
 761         adjustment instruction.  Metaware R2.3u compiler moves other
 762         things in front of it.  This fix isn't perfect but is what's
 763         running.
 764
 765 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 766
 767         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 768
 769         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 770         character filenames.
 771         * configure.in: Change accordingly.
 772
 773 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 774
 775         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 776         _filtered io routines from these two files.
 777
 778 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 779
 780         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 781         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 782         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 783         DEC c89.
 784         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 785
 786 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 787
 788         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 789         printing to gdb_stderr.
 790
 791         * remote-udi.c (udi_kill): Don't close the connection, just set
 792         inferior_pid to zero.
 793         (udi_mourn): Call remove_breakpoints.
 794
 795         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 796
 797         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 798
 799 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 800
 801         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 802
 803         * remote-bug.c: At the start of each section, reset srec_frame
 804         back to 160.
 805
 806         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 807         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 808         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 809         code which looks for those two waitkinds.  Use switch statement.
 810         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 811         CHILD_SPECIAL_WAITSTATUS.
 812
 813         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 814         * Move target_signal_from_host, target_signal_to_host, and
 815         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 816         * target.c: Include "wait.h" and <signal.h>.
 817         * target.h, infrun.c (proceed), proceed callers: Pass new code
 818         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 819         enums being treated as unsigned and is cleaner.
 820         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 821         TARGET_SIGNAL_0.
 822         * infcmd.c (signal_command), infrun.c (signals_info):
 823         Don't allow user to specify numeric equivalent of
 824         TARGET_SIGNAL_DEFAULT.
 825
 826 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 827
 828         * config/alpha/alpha-netware.mt:  New target support for Alpha
 829         running Netware.
 830         * configure.in:  Add alpha-*-netware* target.
 831
 832 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 833
 834         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 835
 836 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 837
 838         * target.h: Add enum target_waitkind, enum target_signal, and
 839         struct target_waitstatus.  Change status argument to target_wait to
 840         be struct target_waitstatus * instead of int *.
 841         * target.h, infrun.c, all targets: Change type of signal arguments
 842         to resume(), proceed(), and target_resume() from int to enum
 843         target_signal.
 844         * All targets (*_wait, *_resume): Change accordingly.
 845         * infcmd.c (program_info, signal_command), throughout infrun.c,
 846         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 847         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 848         signal code stuff right with the new signals would be non-trivial).
 849         * inferior.h (stop_signal): Make it enum target_signal not int.
 850         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 851         target_signal_from_name): New functions.
 852         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 853         store_waitstatus): New functions.
 854         * procfs.c (procfs_notice_signals): Use them.
 855         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 856         print_fault.
 857         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 858
 859         * objfiles.c (build_objfile_section_table): Don't abort() if
 860         objfile->sections is already set.
 861
 862         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 863         to match recent change to exec.c.
 864
 865         * Version 4.11.3.
 866
 867         * main.c (print_gdb_version): Change year to 1994.
 868
 869         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 870         * Makefile.in (NONSRC): Add ChangeLog-93.
 871
 872 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 873
 874         * stabsread.c (read_type): Allow defining several type numbers
 875         at once (e.g. "(1,2)=(3,4)="...).
 876
 877         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 878
 879         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 880
 881 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 882
 883         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 884         to process_one_symbol.
 885         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 886         avoid caching a bad endaddr in find_pc_partial_function.
 887
 888 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 889
