   1 Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)
   2
   3         * sparc-stub.c:  Remove unnecessary #include of memory.h.
   4
   5 Mon Jan 31 12:12:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   6
   7         * mips-tdep.c: Remove code which sets saved_regs from
   8         init_extra_frame_info and put it in new function mips_find_saved_regs.
   9         (READ_FRAME_REG): Remove macro and replace uses with the expansion.
  10         * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
  11         check if it is NULL and call mips_find_saved_regs if so.
  12
  13         * remote-mips.c: Use unfiltered, not filtered, output most places.
  14
  15         * blockframe.c (get_prev_frame_info): Detect and stop an infinite
  16         backtrace.  Revise comments.
  17
  18 Mon Jan 31 09:40:33 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  19
  20         * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
  21         alpha and irix. The _sigtramp case has to be handled properly
  22         in the tdep files if we have no ecoff debugging info.
  23         * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
  24         mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
  25         without PC_REGNUM kludge.
  26         * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
  27         Clean up handling of mips sigtramp frames, improve comments.
  28
  29 Sat Jan 29 23:25:57 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  30
  31         * paread.c (read_unwind_info): Fix typo.
  32
  33         * paread.c (pa_symtab_read): Update the "check_strange_names"
  34         filter to match GCC's current output.  Filter out section symbols
  35         (which the HP linker sometimes puts in the wrong place).
  36
  37 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  38
  39         * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
  40
  41         * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
  42
  43         * Makefile.in: Remove all references to sparcly-nat.c.
  44
  45         * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
  46         remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
  47         duplicating serial.h and target.h.
  48
  49         * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
  50         are not used anywhere (a 5 Oct 1993 change removed the uses).
  51
  52         * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
  53         * config/m68k/es1800.mt: Add comment.
  54         * remote-es.c: Extensive changes to update to current conventions.
  55
  56         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
  57         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
  58         to achieve the desired timeout.
  59         * serial.h (serial_t): Add field timeout_remaining.
  60
  61 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  62
  63         * c-exp.y (yylex): Reenable nested type code.
  64
  65 Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  66
  67         * a29k-tdep.c (examine_tag): Add comment regarding argcount.
  68
  69         * remote-mips.c (mips_ops): Fix docstring.
  70
  71         * remote-bug.c (bug_ops): Remove spurious newline from docstring.
  72
  73         * config/m68k/tm-monitor.h: Changes to bring this into accordance
  74         with the old tm-m68k-em.h:
  75         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
  76         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
  77         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
  78         Add FIXME regarding GET_LONGJMP_TARGET.
  79
  80         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
  81         * infptrace.c (kill_inferior): Add comments.
  82         * main.c (quit_command): Call target_close after we kill or
  83         detach.
  84         * remote-udi.c (udi_close): Don't error() if QUITTING.
  85
  86 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
  87
  88         * configure.in: Make m68k-coff and aout add monitor support in
  89         addition to the standard serial support.
  90
  91 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  92
  93         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
  94         index indexNil.
  95
  96 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  97
  98         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
  99         * elfread.c (record_minimal_symbol_and_info),
 100         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
 101
 102 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 103
 104         * i386-stub.c: Add ".text" right before "mem_fault:".
 105
 106         * main.c (baud_rate): Add FIXME comment about printing -1 value.
 107
 108         * remote-utils.c (usage): Fix message to be accurate and conform
 109         more closely to normal conventions.
 110
 111         * remote-utils.c (gr_files_info): Have the exec_bfd test control
 112         whether to show information about exec_bfd, and not control whether
 113         to show information about device and speed.
 114
 115         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
 116         usage message, don't dump core.
 117
 118         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
 119         for variable size array.
 120         (bug_fetch_register, bug_store_register): Rename "value" to
 121         "fpreg_buf" because some compilers don't like variables whose
 122         names are the same as types.
 123         (bug_store_register): Use a cast when converting char * to
 124         unsigned char *.
 125
 126         * symmisc.c (maintenance_print_symbols): Don't refer to the name
 127         of the command in error message (the text was referring to the old
 128         name of the command).
 129
 130         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
 131
 132         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
 133         full details on structure elements without names.  This partially
 134         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
 135         of those changes was accidental.
 136
 137         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
 138         defined, make it an error to specify a single argument which is not
 139         a frame number.
 140
 141         * Makefile.in (version.c), main.c (print_gdb_version): Use
 142         host_alias and target_alias, not host_canonical and
 143         target_canonical, to print configuration.
 144
 145 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 146
 147         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
 148         of builtin_type_long.  It is necessary to get a type which is
 149         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
 150
 151         Fix many sins which will come up in 32 bit x 64 bit GDB, and
 152         various miscellaneous things discovered in the process:
 153         * printcmd.c, defs.h (print_address_numeric): New function.
 154         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 155         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 156         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 157         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 158         Use it.
 159         * utils.c, defs.h (gdb_print_address): New function.
 160         * expprint (dump_expression), gdbtypes.h: Use it.
 161         * breakpoint.c (describe_other_breakpoints),
 162         symmisc.c (dump_symtab, print_symbol):
 163         Use filtered not unfiltered I/O.
 164         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 165         just run gdb under a debugger for this (and it had problems with
 166         printing addresses, how to print b->shadow, etc.).
 167         * buildsym.c (make_blockvector), core.c (memory_error),
 168         exec.c (print_section_info), maint.c (print_section_table),
 169         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 170         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 171         Add comments saying code is broken.  Marked with "FIXME-32x64".
 172         * dbxread.c (process_one_symbol), partial-stab.h (default),
 173         remote-vx.c (vx_run_files_info):
 174         Don't cast int being passed to local_hex_string.
 175         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 176         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 177         only being a long.
 178         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 179         and LOC_LOCAL.
 180         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 181         * source.c: Include <sys/types.h> regardless of USG.
 182
 183 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 184
 185         * valops.c (value_assign):  Set `type' after coercing toval.
 186         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 187         Use extract_unsigned_integer to get the address of a reference.
 188
 189 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 190
 191         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 192         AIX can use ? instead of \ for continuation.  Deal with it.
 193
 194         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 195         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 196         the HP compiler in ANSI mode doesn't like.
 197
 198         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 199         based on USG, rather than defining HAVE_SIGSETMASK to an
 200         expression containing defined.  Having a macro used in #if expand
 201         to an expression containing "defined" is undefined according to
 202         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 203         it to.
 204
 205 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 206
 207         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 208         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 209
 210 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 211
 212         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 213         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 214
 215 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 216
 217         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 218         passing them to print_387_status.
 219         (print_387_status): Don't subtract top from 7 before using it.
 220         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 221         from 7; the above explains it.
 222
 223 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 224
 225         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 226         pointer value when fixing up the frame at the start of a function.
 227
 228 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 229
 230         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 231         Sparc from the stack.
 232
 233 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 234
 235         * remote-mips.c (mips_initialize): Clear mips_initializing via
 236         cleanup chain, not directly.
 237
 238         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 239         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 240         munging the timeout due to the limited range of c_cc[VTIME].
 241
 242         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 243         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
 244         m3-nat.c (m3_create_inferior): Pass it.
 245         * procfs.c: Remove ptrace function.  It was declared in a way which
 246         conflicted with the prototype in unistd.h on Solaris.
 247
 248 Sat Jan 22 01:37:40 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 249
 250         * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
 251         in the sigcontext if it is a signal trampoline frame.
 252         * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
 253         Define for Solaris2.
 254
 255 Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)
 256
 257         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 258         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 259         tm-sparc.h so they can be overridden if necessary.
 260
 261 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 262
 263         * lynx-nat.c:  Add Sparc support.
 264         * sparcly-nat.c:  Remove.  It's useless.
 265         * config/sparc/nm-sparclynx.h:  Rewrite.
 266         * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
 267         with lynx-nat.o
 268         * config/sparc/tm-sparclynx.h:  Rewrite.
 269
 270 Fri Jan 21 19:08:48 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 271
 272         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 273         directory.  Old code was discarded, since the new opcode table has
 274         a different format.
 275
 276 Fri Jan 21 14:28:30 1994  Fred Fish  (fnf@cygnus.com)
 277
 278         * Makefile.in (realclean):  Remove info files per make-stds.texi.
 279
 280 Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 281
 282         * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
 283         if N_SO_ADDRESS_MAYBE_MISSING is defined.
 284         * config/sparc/tm-sun4sol2.h: Define it.
 285
 286 Thu Jan 20 15:04:24 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 287
 288         * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
 289         if we did not find a symbol.
 290
 291 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 292
 293         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 294         is not defined.
 295
 296         * hppab-nat.c (call_ptrace): Delete redundant function.
 297         (kill_inferior, attach, detach, child_resume): Likewise.
 298         (child_xfer_memory): Likewise.
 299
 300         * hppah-nat.c (call_ptrace): Delete redundant function.
 301         (kill_inferior, attach, detach, child_resume): Likewise.
 302
 303         * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
 304
 305         * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
 306
 307         * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
 308
 309         * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
 310         (CHILD_XFER_MEMORY): Define.
 311         (PT_*): Define so that generic infptrace.c code can be used.
 312
 313 Fri Jan 21 09:23:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 314
 315         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 316         struct section_offsets *, not a (nonexistent) struct section_offset *.
 317
 318         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 319         internal_xcoff_symtab, not an array of one of them.  Change lots of
 320         "main_aux" to "&main_aux" and so on.
 321
 322         * coffread.c, xcoffread.c: Include <coff/internal.h>
 323         before "symfile.h".
 324
 325 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 326
 327         * coffread.c (coff_getfilename): Make it not static.
 328
 329         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 330
 331         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 332         a completely gratuitous difference between xcoffread.c and coffread.c).

 335
 336         * infrun.c (wait_for_inferior): Don't set frame for
 337         step_resume_breakpoint for IN_SIGTRAMP cases.
 338
 339         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 340         breakpoint.c (bpstat_what): Move step_resume from its own field of
 341         the struct bpstat_what into the main_action.  Make it override
 342         other breakpoints.  This is a conservative change in the sense
 343         that before the step resume breakpoint was a breakpoint.c
 344         breakpoint, hitting the step resume breakpoint overrode even
 345         calling bpstat_stop_status.
 346

 348
 349         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
 350         in case execution was stopped in the called function.
 351         * stack.c (print_frame_info, frame_info):  If backtracing through
 352         a call dummy, handle the starting source line number on a line
 353         boundary like backtracing through sigtramp.
 354         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 355         for call dummy frame right.  Remove old test for dummy frame,
 356         it has been unused at least since gdb-3.5.
 357         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 358         of the dummy frame.

 389         * paread.c (compare_unwind_entries): New function for sorting
 390         unwind table entries.
 391         (read_unwind_info): Rewrite to remove dependency on host endianness.
 392         Read in data from the $UNWIND_END$ subspace which contains linker
 393         stub unwind descriptors.  Merge that data into the basic unwind
 394         table.
 395
 396         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 397
 398 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 399
 400         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
 401         from either the symbol name or the auxent.
 402         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 403         no longer static.

 406
 407         * Makefile.in (ALLPARAM):  Change irix5.h to nm-irix5.h.

 438
 439         * main.c (show_commands):  Make return type of extern
 440         history_get be HIST_ENTRY, rather than struct _hist_entry.
 441         (The latter loses with the upcoming merged readline.)
 442

 444
 445         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring

 447
 448         * symtab.h (struct symbol): Make section short, not unsigned short.
 449
 450         * symtab.c (lookup_symbol): Add comment about QUIT here.
 451
 452         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 453
 454         * c-exp.y (parse_number): Check for overflow regardless of range
 455         checking.  Fix overflow check to use unsigned LONGEST, not
 456         unsigned int.
 457
 458         * c-exp.y (parse_number): Make it so that integer constants are
 459         builtin_type_long_long if builtin_type_long isn't big enough or if
 460         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 461
 462         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 463         Print our "()" first, then recurse for the target type.
 464
 465 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 466
 467         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 468
 469         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".

 472
 473         * utils.c (request_quit): Re-establish signal handler regardless

 487
 488         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 489         changes (status -> ourstatus; declare status, etc.).
 490         * config/nm-lynx.h: Fix child_wait prototype and include target.h.

 498         * remote-mips.c (mips_request, mips_wait): Correct prototypes.

 508 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 509
 510         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 511         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 512
 513         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 514         writing it.
 515
 516         Add search to target vector (#if 0'd until after 4.12):
 517         * target.h (to_search, target_search): Add.
 518         * gdbcore.h, core.c (generic_search): Add.
 519         * remote.c (remote_search): Add.
 520         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 521         tag.
 522
 523         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 524         is on, call find_pc_function rather than relying just on the minimal
 525         symbols (probably only matters for symbol readers which don't put
 526         statics in the minimal symbols, but changing this strikes me as
 527         not conservative enough).
 528         Initialize name_location in all cases.
 529         If no symbol and no msymbol, don't print anything symbolic.
 530
 531         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 532
 533 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 534
 535         * printcmd.c (print_address_symbolic):  Make it search the
 536         symtabs for variables as well as functions.  Add `set print
 537         fast-symbolic-addr' and default it to fast (the old way).
 538         Print line numbers for data items as well as functions.
 539
 540         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 541         address, if a symbol is found (take two more args pointing to
 542         where to store these results).
 543
 544         * symtab.h (find_addr_symbol):  Add prototype.
 545
 546 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 547
 548         * objfiles.h: Fix comments to reflect the fact that the phrase
 549         "top of stack" always refers to where the pushing and popping takes
 550         place, regardless of whether it is at the highest or lowest address.
 551
 552 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 553
 554         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 555         compiler generated tag names.
 556         * mdebugread.c (parse_type):  Handle cross references to qualified
 557         aggregate types.
 558         * valops.c (value_struct_elt):  Improve error message if the
 559         address of a method is requested from an object instance.
 560         * valops.c (search_struct_method):  Make name_matched non-static
 561         to get it initialized correctly.
 562         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 563         exclude segment register which are not writable on newer SCO versions.
 564
 565 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 566
 567         * go32-xdep.c: Remove unused function uerror.
 568         (sigsetmask): Declare return type.  Declare argument (to match the
 569         way it is called).  Explicitly return 0.
 570
 571 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 572
 573         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 574         partial_symbol):  Shrink the storage sizes of symbols, by making
 575         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 576         enums and small ints to the end of each struct to improve
 577         alignment, and switching the section number from int to unsigned
 578         short.
 579
 580 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 581
 582         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 583         symbol associated with an address.  It does so by exhaustive
 584         search of the symtabs, so it's slow but complete.
 585
 586 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 587
 588         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 589         to [0,0] rather than [0, end of first source file].  This avoids
 590         problems with other parts of GDB looking for linetables in the
 591         _globals_ symtab.  Eliminate variables num_object_files and
 592         first_object_file_end.
 593
 594 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)

 598         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 599         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 600         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 601         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 602         (SETUP_ARBITRARY_FRAME):  Define.

 604 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 605
 606         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 607
 608 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 609

 611
 612 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 613
 614         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 615         hppa_frame_find_saved_regs.
 616         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 617         (prologue_inst_adjust_sp): New function.
 618         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 619         (skip_prologue): Completely rewrite to use unwind information.
 620         (hppa_frame_find_saved_regs): Likewise.
 621
 622 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 623
 624         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 625         to convert a signal number with appropriate bounds checking.
 626
 627         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 628
 629 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 630
 631         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 632         print a newline to end the display anyway.
 633
 634         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 635         coprocessor status regs) when popping a frame.  This fixes
 636         float exceptions that occur after calling inferior functions.
 637
 638         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 639         Read and write the fsr (float status register) to/from the child
 640         process along with the float regs.  Remove Peter Schauer's change
 641         of May 24 '93, which has higher overhead and doesn't solve the
 642         real problem (which was that FSR wasn't being set).
 643
 644 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 645
 646         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 647         stack overflow check isn't right after the register stack
 648         adjustment instruction.  Metaware R2.3u compiler moves other
 649         things in front of it.  This fix isn't perfect but is what's
 650         running.
 651
 652 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 653
 654         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 655
 656         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 657         character filenames.
 658         * configure.in: Change accordingly.
 659
 660 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 661
 662         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 663         _filtered io routines from these two files.
 664
 665 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 674
 675         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 676         printing to gdb_stderr.
 677
 678         * remote-udi.c (udi_kill): Don't close the connection, just set
 679         inferior_pid to zero.
 680         (udi_mourn): Call remove_breakpoints.
 681
 682         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 683
 684         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.

 686 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 687
 688         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 689
 690         * remote-bug.c: At the start of each section, reset srec_frame
 691         back to 160.
 692
 693         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 694         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 695         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 696         code which looks for those two waitkinds.  Use switch statement.
 697         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 698         CHILD_SPECIAL_WAITSTATUS.
 699
 700         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 701         * Move target_signal_from_host, target_signal_to_host, and
 702         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 703         * target.c: Include "wait.h" and <signal.h>.
 704         * target.h, infrun.c (proceed), proceed callers: Pass new code
 705         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 706         enums being treated as unsigned and is cleaner.
 707         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 708         TARGET_SIGNAL_0.
 709         * infcmd.c (signal_command), infrun.c (signals_info):
 710         Don't allow user to specify numeric equivalent of

 724
 725         * target.h: Add enum target_waitkind, enum target_signal, and
 726         struct target_waitstatus.  Change status argument to target_wait to
 727         be struct target_waitstatus * instead of int *.
 728         * target.h, infrun.c, all targets: Change type of signal arguments
 729         to resume(), proceed(), and target_resume() from int to enum
 730         target_signal.
 731         * All targets (*_wait, *_resume): Change accordingly.
 732         * infcmd.c (program_info, signal_command), throughout infrun.c,
 733         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 734         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 735         signal code stuff right with the new signals would be non-trivial).
 736         * inferior.h (stop_signal): Make it enum target_signal not int.
 737         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 738         target_signal_from_name): New functions.
 739         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 740         store_waitstatus): New functions.
 741         * procfs.c (procfs_notice_signals): Use them.

 743         print_fault.
 744         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 745
 746         * objfiles.c (build_objfile_section_table): Don't abort() if
 747         objfile->sections is already set.
 748
 749         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 750         to match recent change to exec.c.

 754         * main.c (print_gdb_version): Change year to 1994.
 755

 760
 761         * stabsread.c (read_type): Allow defining several type numbers
 762         at once (e.g. "(1,2)=(3,4)="...).
 763
 764         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).

 771         to process_one_symbol.
 772         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 773         avoid caching a bad endaddr in find_pc_partial_function.
