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

 379         (read_unwind_info): Rewrite to remove dependency on host endianness.
 380         Read in data from the $UNWIND_END$ subspace which contains linker

 383
 384         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.

 426
 427         * main.c (show_commands):  Make return type of extern
 428         history_get be HIST_ENTRY, rather than struct _hist_entry.

 439
 440         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 441
 442         * c-exp.y (parse_number): Check for overflow regardless of range
 443         checking.  Fix overflow check to use unsigned LONGEST, not
 444         unsigned int.
 445
 446         * c-exp.y (parse_number): Make it so that integer constants are
 447         builtin_type_long_long if builtin_type_long isn't big enough or if
 448         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 449
 450         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 451         Print our "()" first, then recurse for the target type.

 497
 498         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 499         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 500
 501         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 502         writing it.
 503
 504         Add search to target vector (#if 0'd until after 4.12):
 505         * target.h (to_search, target_search): Add.
 506         * gdbcore.h, core.c (generic_search): Add.
 507         * remote.c (remote_search): Add.
 508         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 509         tag.
 510
 511         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 512         is on, call find_pc_function rather than relying just on the minimal
 513         symbols (probably only matters for symbol readers which don't put
 514         statics in the minimal symbols, but changing this strikes me as
 515         not conservative enough).
 516         Initialize name_location in all cases.
 517         If no symbol and no msymbol, don't print anything symbolic.
 518
 519         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 520
 521 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 522
 523         * printcmd.c (print_address_symbolic):  Make it search the
 524         symtabs for variables as well as functions.  Add `set print
 525         fast-symbolic-addr' and default it to fast (the old way).
 526         Print line numbers for data items as well as functions.
 527
 528         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 529         address, if a symbol is found (take two more args pointing to
 530         where to store these results).
 531
 532         * symtab.h (find_addr_symbol):  Add prototype.
 533
 534 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 535
 536         * objfiles.h: Fix comments to reflect the fact that the phrase
 537         "top of stack" always refers to where the pushing and popping takes
 538         place, regardless of whether it is at the highest or lowest address.
 539
 540 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 541
 542         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 543         compiler generated tag names.
 544         * mdebugread.c (parse_type):  Handle cross references to qualified
 545         aggregate types.
 546         * valops.c (value_struct_elt):  Improve error message if the
 547         address of a method is requested from an object instance.
 548         * valops.c (search_struct_method):  Make name_matched non-static
 549         to get it initialized correctly.
 550         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 551         exclude segment register which are not writable on newer SCO versions.
 552
 553 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 554
 555         * go32-xdep.c: Remove unused function uerror.
 556         (sigsetmask): Declare return type.  Declare argument (to match the
 557         way it is called).  Explicitly return 0.
 558
 559 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 560
 561         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 562         partial_symbol):  Shrink the storage sizes of symbols, by making
 563         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 564         enums and small ints to the end of each struct to improve
 565         alignment, and switching the section number from int to unsigned
 566         short.
 567
 568 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 569
 570         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 571         symbol associated with an address.  It does so by exhaustive
 572         search of the symtabs, so it's slow but complete.
 573
 574 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 575
 576         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 577         to [0,0] rather than [0, end of first source file].  This avoids
 578         problems with other parts of GDB looking for linetables in the
 579         _globals_ symtab.  Eliminate variables num_object_files and
 580         first_object_file_end.
 581
 582 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)

 587         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 588         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 589         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.

 604         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 605         (prologue_inst_adjust_sp): New function.
 606         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 607         (skip_prologue): Completely rewrite to use unwind information.
 608         (hppa_frame_find_saved_regs): Likewise.
 609
 610 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 611
 612         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 613         to convert a signal number with appropriate bounds checking.
 614
 615         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 616
 617 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 618
 619         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 620         print a newline to end the display anyway.
 621
 622         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 623         coprocessor status regs) when popping a frame.  This fixes
 624         float exceptions that occur after calling inferior functions.
 625
 626         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 627         Read and write the fsr (float status register) to/from the child
 628         process along with the float regs.  Remove Peter Schauer's change
 629         of May 24 '93, which has higher overhead and doesn't solve the
 630         real problem (which was that FSR wasn't being set).
 631
 632 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 633
 634         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 635         stack overflow check isn't right after the register stack
 636         adjustment instruction.  Metaware R2.3u compiler moves other
 637         things in front of it.  This fix isn't perfect but is what's
 638         running.
 639
 640 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 641
 642         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 643
 644         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 645         character filenames.
 646         * configure.in: Change accordingly.
 647
 648 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 649

 664         printing to gdb_stderr.
 665
 666         * remote-udi.c (udi_kill): Don't close the connection, just set
 667         inferior_pid to zero.
 668         (udi_mourn): Call remove_breakpoints.
 669
 670         * remote-udi.c: Remove obsolete need_artificial_traps comment.

 676         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 677
 678         * remote-bug.c: At the start of each section, reset srec_frame
 679         back to 160.
 680
 681         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 682         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 683         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 684         code which looks for those two waitkinds.  Use switch statement.
 685         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 686         CHILD_SPECIAL_WAITSTATUS.
 687
 688         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 689         * Move target_signal_from_host, target_signal_to_host, and
 690         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 691         * target.c: Include "wait.h" and <signal.h>.
 692         * target.h, infrun.c (proceed), proceed callers: Pass new code
 693         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 694         enums being treated as unsigned and is cleaner.
 695         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 696         TARGET_SIGNAL_0.
 697         * infcmd.c (signal_command), infrun.c (signals_info):
 698         Don't allow user to specify numeric equivalent of
 699         TARGET_SIGNAL_DEFAULT.

 701 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 702
 703         * config/alpha/alpha-netware.mt:  New target support for Alpha
 704         running Netware.
 705         * configure.in:  Add alpha-*-netware* target.
 706
 707 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 708
 709         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.

 712
 713         * target.h: Add enum target_waitkind, enum target_signal, and
 714         struct target_waitstatus.  Change status argument to target_wait to
 715         be struct target_waitstatus * instead of int *.
 716         * target.h, infrun.c, all targets: Change type of signal arguments
 717         to resume(), proceed(), and target_resume() from int to enum
 718         target_signal.
 719         * All targets (*_wait, *_resume): Change accordingly.
 720         * infcmd.c (program_info, signal_command), throughout infrun.c,
 721         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 722         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 723         signal code stuff right with the new signals would be non-trivial).
 724         * inferior.h (stop_signal): Make it enum target_signal not int.
 725         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 726         target_signal_from_name): New functions.
 727         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 728         store_waitstatus): New functions.
 729         * procfs.c (procfs_notice_signals): Use them.
 730         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 731         print_fault.
 732         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 733
 734         * objfiles.c (build_objfile_section_table): Don't abort() if
 735         objfile->sections is already set.
 736
 737         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 738         to match recent change to exec.c.
 739
 740         * Version 4.11.3.
 741
 742         * main.c (print_gdb_version): Change year to 1994.
 743
 744         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 745         * Makefile.in (NONSRC): Add ChangeLog-93.

 748
 749         * stabsread.c (read_type): Allow defining several type numbers
 750         at once (e.g. "(1,2)=(3,4)="...).
 751
 752         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 753
 754         * breakpoint.c (frame_in_dummy): Check PC as well as frame.

 757
 758         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 759         to process_one_symbol.
 760         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 761         avoid caching a bad endaddr in find_pc_partial_function.

 764
 765         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
