  44         unwind table entries.
  45         (read_unwind_info): Rewrite to remove dependency on host endianness.
  46         Read in data from the $UNWIND_END$ subspace which contains linker
  47         stub unwind descriptors.  Merge that data into the basic unwind
  48         table.

  92
  93         * main.c (show_commands):  Make return type of extern
  94         history_get be HIST_ENTRY, rather than struct _hist_entry.
  95         (The latter loses with the upcoming merged readline.)
  96
  97 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  98
  99         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring

 103
 104         * symtab.c (lookup_symbol): Add comment about QUIT here.
 105
 106         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 107
 108         * c-exp.y (parse_number): Check for overflow regardless of range
 109         checking.  Fix overflow check to use unsigned LONGEST, not
 110         unsigned int.
 111
 112         * c-exp.y (parse_number): Make it so that integer constants are
 113         builtin_type_long_long if builtin_type_long isn't big enough or if
 114         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 115
 116         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 117         Print our "()" first, then recurse for the target type.
 118
 119 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 120
 121         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.

 126
 127         * utils.c (request_quit): Re-establish signal handler regardless
 128         of USG.
 129
 130         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 131
 132 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 133

 135
 136 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 137
 138         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 139
 140 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 141
 142         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 143         changes (status -> ourstatus; declare status, etc.).
 144         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 145
 146 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 147
 148         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
 149
 150 Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 151
 152         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
 153
 154 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 155
 156         * config/i386/xm-linux.h: Define HAVE_TERMIOS.
 157
 158 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 160         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
 161
 162 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 163
 164         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 165         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 166
 167         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 168         writing it.
 169
 170         Add search to target vector (#if 0'd until after 4.12):
 171         * target.h (to_search, target_search): Add.
 172         * gdbcore.h, core.c (generic_search): Add.
 173         * remote.c (remote_search): Add.
 174         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 175         tag.
 176
 177         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 178         is on, call find_pc_function rather than relying just on the minimal
 179         symbols (probably only matters for symbol readers which don't put
 180         statics in the minimal symbols, but changing this strikes me as
 181         not conservative enough).
 182         Initialize name_location in all cases.
 183         If no symbol and no msymbol, don't print anything symbolic.
 184
 185         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 186
 187 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 188
 189         * printcmd.c (print_address_symbolic):  Make it search the
 190         symtabs for variables as well as functions.  Add `set print
 191         fast-symbolic-addr' and default it to fast (the old way).
 192         Print line numbers for data items as well as functions.
 193
 194         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 195         address, if a symbol is found (take two more args pointing to
 196         where to store these results).
 197
 198         * symtab.h (find_addr_symbol):  Add prototype.
 199
 200 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 201
 202         * objfiles.h: Fix comments to reflect the fact that the phrase
 203         "top of stack" always refers to where the pushing and popping takes
 204         place, regardless of whether it is at the highest or lowest address.
 205
 206 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 207
 208         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 209         compiler generated tag names.
 210         * mdebugread.c (parse_type):  Handle cross references to qualified
 211         aggregate types.
 212         * valops.c (value_struct_elt):  Improve error message if the
 213         address of a method is requested from an object instance.
 214         * valops.c (search_struct_method):  Make name_matched non-static
 215         to get it initialized correctly.
 216         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 217         exclude segment register which are not writable on newer SCO versions.
 218
 219 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 220
 221         * go32-xdep.c: Remove unused function uerror.
 222         (sigsetmask): Declare return type.  Declare argument (to match the
 223         way it is called).  Explicitly return 0.
 224
 225 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 226
 227         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 228         partial_symbol):  Shrink the storage sizes of symbols, by making
 229         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 230         enums and small ints to the end of each struct to improve
 231         alignment, and switching the section number from int to unsigned
 232         short.
 233
 234 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 235
 236         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 237         symbol associated with an address.  It does so by exhaustive
 238         search of the symtabs, so it's slow but complete.
 239
 240 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 241
 242         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 243         to [0,0] rather than [0, end of first source file].  This avoids
 244         problems with other parts of GDB looking for linetables in the
 245         _globals_ symtab.  Eliminate variables num_object_files and
 246         first_object_file_end.
 247
 248 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)

 251         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 252         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 253         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 254         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 255         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 256         (SETUP_ARBITRARY_FRAME):  Define.
 257
 258 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 259
 260         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 261
 262 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 263
 264         * remote-udi.c (udi_resume): Correct prototype.
 265
 266 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 267
 268         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 269         hppa_frame_find_saved_regs.
 270         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 271         (prologue_inst_adjust_sp): New function.
 272         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 273         (skip_prologue): Completely rewrite to use unwind information.
 274         (hppa_frame_find_saved_regs): Likewise.
 275
 276 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 277
 278         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 279         to convert a signal number with appropriate bounds checking.
 280
 281         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 282
 283 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 284
 285         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 286         print a newline to end the display anyway.
 287
 288         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 289         coprocessor status regs) when popping a frame.  This fixes
 290         float exceptions that occur after calling inferior functions.
 291
 292         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 293         Read and write the fsr (float status register) to/from the child
 294         process along with the float regs.  Remove Peter Schauer's change
 295         of May 24 '93, which has higher overhead and doesn't solve the
 296         real problem (which was that FSR wasn't being set).
 297
 298 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 299
 300         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 301         stack overflow check isn't right after the register stack
 302         adjustment instruction.  Metaware R2.3u compiler moves other
 303         things in front of it.  This fix isn't perfect but is what's
 304         running.
 305
 306 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 307
 308         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 309
 310         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 311         character filenames.
 312         * configure.in: Change accordingly.
 313
 314 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 315
 316         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 317         _filtered io routines from these two files.
 318
 319 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 320
 321         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 322         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 323         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 324         DEC c89.
 325         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 326
 327 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 328
 329         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 330         printing to gdb_stderr.
 331
 332         * remote-udi.c (udi_kill): Don't close the connection, just set
 333         inferior_pid to zero.
 334         (udi_mourn): Call remove_breakpoints.
 335
 336         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 337
 338         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 339
 340 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 341
 342         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 343
 344         * remote-bug.c: At the start of each section, reset srec_frame
 345         back to 160.
 346
 347         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 348         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 349         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 350         code which looks for those two waitkinds.  Use switch statement.
 351         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 352         CHILD_SPECIAL_WAITSTATUS.
 353
 354         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 355         * Move target_signal_from_host, target_signal_to_host, and
 356         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 357         * target.c: Include "wait.h" and <signal.h>.
 358         * target.h, infrun.c (proceed), proceed callers: Pass new code
 359         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 360         enums being treated as unsigned and is cleaner.
 361         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 362         TARGET_SIGNAL_0.
 363         * infcmd.c (signal_command), infrun.c (signals_info):
 364         Don't allow user to specify numeric equivalent of
 365         TARGET_SIGNAL_DEFAULT.
 366
 367 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 368
 369         * config/alpha/alpha-netware.mt:  New target support for Alpha
 370         running Netware.
 371         * configure.in:  Add alpha-*-netware* target.
 372
 373 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 374
 375         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 376
 377 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 378
 379         * target.h: Add enum target_waitkind, enum target_signal, and
 380         struct target_waitstatus.  Change status argument to target_wait to
 381         be struct target_waitstatus * instead of int *.
 382         * target.h, infrun.c, all targets: Change type of signal arguments
 383         to resume(), proceed(), and target_resume() from int to enum
 384         target_signal.
 385         * All targets (*_wait, *_resume): Change accordingly.
 386         * infcmd.c (program_info, signal_command), throughout infrun.c,
 387         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 388         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 389         signal code stuff right with the new signals would be non-trivial).
 390         * inferior.h (stop_signal): Make it enum target_signal not int.
 391         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 392         target_signal_from_name): New functions.
 393         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 394         store_waitstatus): New functions.
 395         * procfs.c (procfs_notice_signals): Use them.
 396         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 397         print_fault.
 398         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 399
 400         * objfiles.c (build_objfile_section_table): Don't abort() if
 401         objfile->sections is already set.
 402
 403         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 404         to match recent change to exec.c.
 405
 406         * Version 4.11.3.
 407
 408         * main.c (print_gdb_version): Change year to 1994.
 409
 410         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 411         * Makefile.in (NONSRC): Add ChangeLog-93.

 413 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 414
 415         * stabsread.c (read_type): Allow defining several type numbers
 416         at once (e.g. "(1,2)=(3,4)="...).
 417
 418         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 419
 420         * breakpoint.c (frame_in_dummy): Check PC as well as frame.

 423
 424         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 425         to process_one_symbol.
 426         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 427         avoid caching a bad endaddr in find_pc_partial_function.
 428
 429 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 430
 431         * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.

 434
 435         * infrun.c (wait_for_inferior):  Do not step or step resume past
 436         the end of a one-line function we just stepped into.
