945 code from prim_record_minimal_symbol_and_info() to here. Callers
946 of the latter can legitimately supply a section number of -1.
948 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
950 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
951 member functions have an element in args for a (nonexistent) this
954 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
956 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.

959 queue if NO_PC_SPACE_QUEUE_RESTORE is defined.
961 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
962 for the structure's type. All callers changed.
964 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
965 for each structure argument rather than assuming it's either
966 true or false for all structure arguments.
968 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
969 on the length structure passed, not the compiler used.
971 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
972 argument for the structure's type.
974 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
976 * values.c (set_internalvar): Don't set var->value until we are

982 Mon Mar 21 13:11:30 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
984 * symmisc.c (maintenance_check_symtabs): New function to check
985 consistency of psymtabs and symtabs.
986 * symtab.h (maintenance_check_symtabs): Add prototype.
987 * maint.c: Add new `maint check-symtabs' command.
988 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
989 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.
990 * config/i386/tm-symmetry.h: Make comment inside #if 0 a real
992 * config/i386/tm-symmetry.h (STORE_STRUCT_RETURN): Cast argument
993 to write_memory to avoid warnings from gcc.
994 * config/i386/xm-symmetry.h: Add missing #endif.

1001 * hppa-tdep.c (hppa_fix_call_dummy): Use value_ptr.
1002 (hppa_push_arguments): Likewise.
1004 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1006 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1007 improve remote debugging efficiency. Also fixed problems with
1008 doing function calls for programs with no entry points.
1009 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1010 entry_point_address.
1011 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1012 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1013 parse_lines): Pass section_offsets info to these routines so that
1014 we can relocate symbol table entries upon readin.
1015 * (psymtab_to_symtab_1): Set symtab->primary to tell
1016 objfile_relocate to do relocations for our symbols.
1017 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1018 (which hang off of the symbol table).
1019 * Use prim_record_minimal_symbols_and_info instead of
1020 prim_record_minimal_symbols to supply section info to make minimal
1021 symbol relocations work.
1022 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1023 -1, try to deduce it from ms_type.
1024 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1025 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1026 add code to relocate objfile->sections data structure.
1027 * remote.c (get_offsets): Use new protocol message to acquire
1028 section offsets from the target.
1029 * (remote_wait): Get rid of relocation stuff. That's all handled
1030 by objfile_relocate now.
1031 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1032 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1034 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1036 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1038 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1042 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1043 can no longer set this at run time.
1044 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1045 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1046 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1047 sparc-tdep.c compiles).
1048 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1051 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1053 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1054 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1055 * configure.in: Recognize m68*-cisco*-*.
1057 * Makefile.in (TAGS): Use variables directly, rather than using
1058 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1059 and means that these filenames no longer need be unique across all
1060 the config/* directories.
1061 * configure.in: Put the config/*/ into TM_FILE, etc.
1063 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1064 and trapv exceptions.
1066 * target.h (struct section_table), objfiles.h (struct obj_section):
1067 Change name of field sec_ptr to the_bfd_section. More mnemonic
1068 and avoids the (sort of, for the ptx compiler) name clash with
1069 the name of the typedef.
1070 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1071 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1073 * utils.c: Include readline.h.
1074 * Makefile.in (utils.o): Add dependency.
1076 * remote.c (getpkt): Add support for run-length encoding.
1078 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1080 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1082 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1084 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1085 prim_record_minimal_symbol.
1088 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1089 computing their offset from the start of the old buffer and adding
1090 to the new buffer, rather than by assuming we can add the
1091 difference between the old buffer and the new buffer (it might not
1092 fit in an int). Merge in cosmetic differences from emacs regex.c
1093 version of this macro.
1095 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1097 * Makefile.in (install-only): Fix use of program_transform_name.
1099 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1101 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1102 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1103 so I'm nuking the command.
1104 * symtab.c (find_addr_symbol): Comment out, no longer used.
1106 * main.c (main): Don't init_source_path for the -cd argument. Now
1107 that source_path doesn't contain the current_directory from when
1108 GDB started up, init_source_path is no longer useful (and is
1109 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1111 * TODO: Remove item about line numbers being off. It is useless
1112 and confusing without a reproducible test case (it mentions
1113 proceed(), but I was able to step through proceed without trouble).
1115 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1117 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1118 library functions before the executable is run. Retrieve dynamic
1119 symbols from stripped executables.
1120 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1121 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1122 symtab.c (list_symbols): Handle mst_solib_trampoline.
1123 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1124 for all targets, remove IBM6000_TARGET dependencies.
1125 * dbxread.c (read_dbx_dynamic_symtab): New function.
1126 * dbxread.c (dbx_symfile_read): Use it.
1127 * dbxread.c (SET_NAMESTRING): Set namestring to
1128 "<bad string table index>" instead of "foo" if the string index is
1130 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1132 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1133 to break_command. Handle mst_file_* minimal symbol types.
1134 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1136 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1138 * c-exp.y(yylex): fix potential memory overflow.
1140 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1142 * environ.c (set_in_environ): Eliminate special handling of PATH and
1144 * putenv.c: Removed, conflicts with system declaration of
1145 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1147 * Makefile.in: Change accordingly.
1148 * procfs.c (procfs_create_inferior): Change comment accordingly.
1150 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1152 * rs6000-tdep.c: Change value to value_ptr.
1154 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1156 * i386m3-nat.c: Include floatformat.h.
1157 (get_i387_state): Use memset not bzero.
1161 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1162 ieee-float.h to floatformat.h.
1164 * valprint.c (val_print_string): Ignore error if the error
1165 happened after a terminating '\0'.
1167 * c-valprint.c (c_val_print): Never add 1 to return value from
1168 val_print_string; just return what it returns.
1170 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1171 looping through all of the enums.
1172 * infrun.c (signals_info): Use it.
1174 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1176 * main.c (main): When printing warning about bad baud rate, don't
1177 use warning(); it relies on current_target which isn't set up yet.
1179 * breakpoint.c (_initialize_breakpoint): Update docstring for
1180 tbreak to match what the code actually does. Don't mention tbreak
1181 in docstrings for "enable once" or "enable breakpoints once".
1183 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1185 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1186 while (0). That defeats the whole purpose of using do . . . while (0).
1187 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1188 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1189 using a ?: expression as an lvalue is not portable.
1191 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1192 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1193 'p' and 'r' symbol descriptors into a single symbol to look for a
1195 * README, config/sparc/tm-sparc.h: Update comments.
1197 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1199 * mdebugread.c (parse_type): Do not complain for types with
1200 an `indexNil' aux index, these are simply undefined types.
1201 Remove indexNil check from caller of parse_type.
1202 * mdebugread.c (parse_partial_symbols): Do not enter
1203 stGlobal, scCommon symbols into the minimal symbol table, their
1204 value is the size of the common, not its address.
1205 Handle scInit, scFini, scPData and scXData sections.
1206 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1208 Enter stProc symbols into the global_psymbols list once, not into
1209 the static_psymbols_list.
1210 Get rid of dummy psymtab if it is empty, to allow proper detection
1211 of stripped executables.
1212 * mdebugread.c (cross_ref): Allow cross references to Fortran
1215 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1217 * stabsread.c (common_block_end, fix_common_block): Stash the
1218 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1219 as to not assume that a pointer fits in an enum.
1221 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1223 * os9kread.c (fill_sym): check compiler verion number for pre-
1225 * os9kread.c (os9k_process_one_symbol): address of symbol is
1226 relative to section not module.
1227 * stabsread.c (define_symbol): add symbol type 's' as local
1229 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1231 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1232 * remote-os9k.c: fix bug in 'set remotebaud' function.
1233 * remote-os9k.c (rombug_link): minimize checking so to improve
1235 * symfile.c (symbol_file_command): check if failed to link, also make
1236 the command be able to accept more than one filenames.
1237 * target.c (target_link): check if failed to link with rombug.
1238 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1240 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1242 * remote-es.c (es1800_child_ops): Don't declare it static.

1250 * dbxread.c: New variable lowest_text_address.
1251 (record_minimal_symbol, read_dbx_symtab): Set it.
1252 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1253 end_of_text_address.
1254 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1256 * dbxread.c (end_psymtab): Remove old and commented out
1257 capping_global and capping_static. Fix comments regarding
1258 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1260 * parser-defs.h: Add "extern" to start of variable declarations so
1261 we don't end up with commons.
1262 * parse.c: Define these variables.
1264 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it

1276 of mapped address segments.
1277 * solib.c (look_for_base, bfd_lookup_symbol): Removed, no longer

1299 * ch-exp.y (match_simple_name_string): Accept '_' as well as an
1300 alphabetic character as the start of a name.
1302 * sparclite/Makefile.in (all install): Build and install aload.
1304 * configure.in: Accept i[34]86-*-*sysv32 because that is what
1305 config.guess and config.sub produce.
1307 * mips-tdep.c: Change value to value_ptr.
1309 Wed Mar 2 09:17:55 1994 Jim Kingdon (kingdon@deneb.cygnus.com)

1327 stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
1328 symm-nat.c. Define CHILD_WAIT and declare child_wait().
1329 * config/i386/tm-symmetry.h: Remove call function stuff; stuff in
1330 tm-i386v.h is apparently OK.
1331 * config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
1332 HAVE_TERMIO. Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
1335 Wed Mar 2 11:31:08 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1337 * osfsolib.c (xfer_link_map_member): Update to use new

1342 * infrun.c (wait_for_inferior): In checking
1343 remove_breakpoints_on_following_step, check
1344 through_sigtramp_breakpoint as well as step_resume_breakpoint.
1346 Tue Mar 1 16:22:56 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1348 * os9kread.c (os9k_process_one_symbol): Rename
1349 VARIABLES_INSIDE_BLOCK to OS9K_VARIABLES_INSIDE_BLOCK.
1350 * symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
1351 (CORE_ADDR)0, from target_link, since that is what it uses.
1352 Process name at end, not during parsing (like we did before Kung's
1353 change), so that -readnow and -mapped can appear anywhere.
1354 Make text_relocation a local variable.
1355 * config/i386/i386os9k.mt: Fix comment.
1356 * Makefile.in (ALLDEPFILES): Add remote-os9k.c.

1446 When looking for '\0', don't increment bufptr and addr if bufptr
1447 started out already at limit. If an error happens on fetching the

1491 which performs one (the check_sigtramp2 one) of the functions
1492 which had been handled by the step_resume_breakpoint. For each
1493 use of the step_resume_breakpoint, make it still use the
1494 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
1496 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
1497 When setting the frame address of the step resume breakpoint, set

1819 * printcmd.c (decode_format): Don't blithely set the size for
1820 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
1822 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
1823 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
1824 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
1825 always just check against INT_MIN and INT_MAX (this also fixes things
1826 if sizeof (long) > sizeof (int), e.g. Alpha).
1827 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
1828 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
1829 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
1830 BUILTIN_TYPE_UNSIGNED_LONGEST.
1831 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
1832 longest_int and longest_unsigned_int.
1833 * value.h (struct value): Just align to LONGEST, rather than worrying
1834 about CC_HAS_LONG_LONG.
1835 * valarith.c (value_binop): Figure out type ourself based on
1836 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
1837 point is that we don't depend on CC_HAS_LONG_LONG anymore.
1838 * valprint.c (val_print_type_code_int): Just call
1839 extract_unsigned_integer directly, rather than going through
1841 * printcmd.c (decode_format): Remove code which would sometimes
1842 change 'g' size to 'w' for integers. print_scalar_formatted handles
1843 printing huge integers well enough, thank you.
1845 * command.c (add_set_cmd, not_just_help_class_command): Change
1846 to make this the sfunc, not cfunc, since that is how we call it.
1847 * command.h: Comment difference between sfunc and cfunc.
1848 * demangle.c (set_demangling_command): Add third arg since that
1849 is how it is called.
1850 (_initialize_demangler): Use sfunc, not cfunc, for
1851 set_demangling_command, since that is how it is called.
1852 Remove show_demangling_command; it has no effect.
1854 * command.c (shell_escape): Report errors correctly (with error
1855 message from strerror).
1857 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1859 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
1860 x_scnlen.l rather than x_scnlen to match corresponding change in
1863 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1865 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
1866 Change comments regarding TYPE_CODE_BOOL.
1867 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
1868 regardless of the language.
1869 (value_true): Just call value_logical_not regardless of language.
1870 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
1871 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
1872 * language.h: Improve comment for la_builtin_type_vector.
1873 * m2-lang.c (_initialize_m2_language): Don't add any fields to
1874 builtin_type_m2_bool.
1876 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
1878 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
1879 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
1881 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1883 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
1884 by restarting the ioctl.
1886 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1888 * target.h (target_wait): Add comment about calling
1889 return_to_top_level.
1891 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1893 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
1894 additional arguments.
1895 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
1897 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
1899 * sparc-stub.c: Remove unnecessary #include of memory.h.
1901 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1903 * mips-tdep.c: Remove code which sets saved_regs from
1904 init_extra_frame_info and put it in new function mips_find_saved_regs.
1905 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
1906 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
1907 check if it is NULL and call mips_find_saved_regs if so.
1909 * remote-mips.c: Use unfiltered, not filtered, output most places.
1911 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
1912 backtrace. Revise comments.
1914 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1916 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
1917 alpha and irix. The _sigtramp case has to be handled properly
1918 in the tdep files if we have no ecoff debugging info.
1919 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
1920 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
1921 without PC_REGNUM kludge.
1922 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
1923 Clean up handling of mips sigtramp frames, improve comments.
1925 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1927 * paread.c (read_unwind_info): Fix typo.
1929 * paread.c (pa_symtab_read): Update the "check_strange_names"
1930 filter to match GCC's current output. Filter out section symbols
1931 (which the HP linker sometimes puts in the wrong place).
1933 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1935 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
1937 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
1939 * Makefile.in: Remove all references to sparcly-nat.c.
1941 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
1942 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
1943 duplicating serial.h and target.h.
1945 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
1946 are not used anywhere (a 5 Oct 1993 change removed the uses).
1948 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
1949 * config/m68k/es1800.mt: Add comment.
1950 * remote-es.c: Extensive changes to update to current conventions.
1952 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
1953 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
1954 to achieve the desired timeout.
1955 * serial.h (serial_t): Add field timeout_remaining.
1957 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1959 * c-exp.y (yylex): Reenable nested type code.
1961 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1963 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
1965 * remote-mips.c (mips_ops): Fix docstring.
1967 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
1969 * config/m68k/tm-monitor.h: Changes to bring this into accordance
1970 with the old tm-m68k-em.h:
1971 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
1972 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
1973 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
1974 Add FIXME regarding GET_LONGJMP_TARGET.
1976 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
1977 * infptrace.c (kill_inferior): Add comments.
1978 * main.c (quit_command): Call target_close after we kill or
1980 * remote-udi.c (udi_close): Don't error() if QUITTING.
1982 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
1984 * configure.in: Make m68k-coff and aout add monitor support in
1985 addition to the standard serial support.
1987 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1989 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
1992 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1994 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
1995 * elfread.c (record_minimal_symbol_and_info),
1996 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
1998 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2000 * i386-stub.c: Add ".text" right before "mem_fault:".
2002 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2004 * remote-utils.c (usage): Fix message to be accurate and conform
2005 more closely to normal conventions.
2007 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2008 whether to show information about exec_bfd, and not control whether
2009 to show information about device and speed.
2011 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2012 usage message, don't dump core.
2014 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2015 for variable size array.
2016 (bug_fetch_register, bug_store_register): Rename "value" to
2017 "fpreg_buf" because some compilers don't like variables whose
2018 names are the same as types.
2019 (bug_store_register): Use a cast when converting char * to
2022 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2023 of the command in error message (the text was referring to the old
2024 name of the command).
2026 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2028 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2029 full details on structure elements without names. This partially
2030 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2031 of those changes was accidental.
2033 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2034 defined, make it an error to specify a single argument which is not
2037 * Makefile.in (version.c), main.c (print_gdb_version): Use
2038 host_alias and target_alias, not host_canonical and
2039 target_canonical, to print configuration.
2041 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2043 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2044 of builtin_type_long. It is necessary to get a type which is
2045 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2047 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2048 various miscellaneous things discovered in the process:
2049 * printcmd.c, defs.h (print_address_numeric): New function.
2050 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2051 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2052 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2053 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2055 * utils.c, defs.h (gdb_print_address): New function.
2056 * expprint (dump_expression), gdbtypes.h: Use it.
2057 * breakpoint.c (describe_other_breakpoints),
2058 symmisc.c (dump_symtab, print_symbol):
2059 Use filtered not unfiltered I/O.
2060 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2061 just run gdb under a debugger for this (and it had problems with
2062 printing addresses, how to print b->shadow, etc.).
2063 * buildsym.c (make_blockvector), core.c (memory_error),
2064 exec.c (print_section_info), maint.c (print_section_table),
2065 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2066 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2067 Add comments saying code is broken. Marked with "FIXME-32x64".
2068 * dbxread.c (process_one_symbol), partial-stab.h (default),
2069 remote-vx.c (vx_run_files_info):
2070 Don't cast int being passed to local_hex_string.
2071 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2072 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2074 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2076 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2077 * source.c: Include <sys/types.h> regardless of USG.
2079 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2081 * valops.c (value_assign): Set `type' after coercing toval.
2082 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2083 Use extract_unsigned_integer to get the address of a reference.
2085 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2087 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2088 AIX can use ? instead of \ for continuation. Deal with it.
2090 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2091 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2092 the HP compiler in ANSI mode doesn't like.
2094 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2095 based on USG, rather than defining HAVE_SIGSETMASK to an
2096 expression containing defined. Having a macro used in #if expand
2097 to an expression containing "defined" is undefined according to
2098 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2101 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2103 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2104 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2106 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2108 * ch-exp.y (match_string_literal): Allow a zero-length string.
2109 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2111 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2113 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2114 passing them to print_387_status.
2115 (print_387_status): Don't subtract top from 7 before using it.
2116 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2117 from 7; the above explains it.
2119 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2121 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2122 pointer value when fixing up the frame at the start of a function.
2124 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2126 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2127 Sparc from the stack.
2129 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2131 * remote-mips.c (mips_initialize): Clear mips_initializing via
2132 cleanup chain, not directly.
2134 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2135 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2136 munging the timeout due to the limited range of c_cc[VTIME].
2138 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2139 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2140 m3-nat.c (m3_create_inferior): Pass it.
2141 * procfs.c: Remove ptrace function. It was declared in a way which
2142 conflicted with the prototype in unistd.h on Solaris.
2144 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2146 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2147 in the sigcontext if it is a signal trampoline frame.
2148 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
2149 Define for Solaris2.
2151 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2153 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2154 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2155 tm-sparc.h so they can be overridden if necessary.
2157 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2159 * lynx-nat.c: Add Sparc support.
2160 * sparcly-nat.c: Remove. It's useless.
2161 * config/sparc/nm-sparclynx.h: Rewrite.
2162 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2164 * config/sparc/tm-sparclynx.h: Rewrite.
2166 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2168 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2169 directory. Old code was discarded, since the new opcode table has
2172 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
2174 * Makefile.in (realclean): Remove info files per make-stds.texi.
2176 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2178 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2179 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2180 * config/sparc/tm-sun4sol2.h: Define it.
2182 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2184 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
2185 if we did not find a symbol.
2187 Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2189 * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
2192 * hppab-nat.c (call_ptrace): Delete redundant function.
2193 (kill_inferior, attach, detach, child_resume): Likewise.
2194 (child_xfer_memory): Likewise.
2196 * hppah-nat.c (call_ptrace): Delete redundant function.
2197 (kill_inferior, attach, detach, child_resume): Likewise.
2199 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2201 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2203 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2205 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2206 (CHILD_XFER_MEMORY): Define.
2207 (PT_*): Define so that generic infptrace.c code can be used.
2209 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2211 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2212 struct section_offsets *, not a (nonexistent) struct section_offset *.
2214 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2215 internal_xcoff_symtab, not an array of one of them. Change lots of
2216 "main_aux" to "&main_aux" and so on.
2218 * coffread.c, xcoffread.c: Include <coff/internal.h>
2221 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2223 * coffread.c (coff_getfilename): Make it not static.
2225 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2227 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2228 a completely gratuitous difference between xcoffread.c and coffread.c).
2230 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2232 * infrun.c (wait_for_inferior): Don't set frame for
2233 step_resume_breakpoint for IN_SIGTRAMP cases.
2235 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2236 breakpoint.c (bpstat_what): Move step_resume from its own field of
2237 the struct bpstat_what into the main_action. Make it override
2238 other breakpoints. This is a conservative change in the sense
2239 that before the step resume breakpoint was a breakpoint.c
2240 breakpoint, hitting the step resume breakpoint overrode even
2241 calling bpstat_stop_status.
2243 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2245 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2246 in case execution was stopped in the called function.
2247 * stack.c (print_frame_info, frame_info): If backtracing through
2248 a call dummy, handle the starting source line number on a line
2249 boundary like backtracing through sigtramp.
2250 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2251 for call dummy frame right. Remove old test for dummy frame,
2252 it has been unused at least since gdb-3.5.
2253 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2256 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2258 * infcmd.c (signal_command): Accept 0 as legitimate signal number.
2260 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2262 * infrun.c (signals_info), target.c (target_signal_from_name):
2263 Use ugly casts to avoid enumvar < enumvar or enumvar++.

2282 by linker stub unwind descriptors.
2283 (frameless_function_invocation): Likewise.
2284 (frame_chain_valid): Likewise.
2285 * paread.c (compare_unwind_entries): New function for sorting
2286 unwind table entries.
2287 (read_unwind_info): Rewrite to remove dependency on host endianness.
2288 Read in data from the $UNWIND_END$ subspace which contains linker
2289 stub unwind descriptors. Merge that data into the basic unwind
2292 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2294 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2296 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2297 from either the symbol name or the auxent.
2298 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2301 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2303 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2305 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2307 * README: Update notes for alpha port.
2309 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2311 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2312 for operation fault, constraint fault, and type fault.

2316 * Makefile.in (init.c): Add comment explaining formatting conventions.
2318 * c-exp.y (parse_number): Assign to temporary between the right
2319 shifts, to work around a bug in the SCO compiler.
2321 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2322 Add various files which were added to GDB recently.
2324 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not

2329 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2333 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2335 * main.c (show_commands): Make return type of extern
2336 history_get be HIST_ENTRY, rather than struct _hist_entry.
2337 (The latter loses with the upcoming merged readline.)
2339 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2341 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2342 const char *, not char *.
2344 * symtab.h (struct symbol): Make section short, not unsigned short.
2346 * symtab.c (lookup_symbol): Add comment about QUIT here.
2348 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2350 * c-exp.y (parse_number): Check for overflow regardless of range
2351 checking. Fix overflow check to use unsigned LONGEST, not
2354 * c-exp.y (parse_number): Make it so that integer constants are
2355 builtin_type_long_long if builtin_type_long isn't big enough or if
2356 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2358 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2359 Print our "()" first, then recurse for the target type.
2361 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2363 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2365 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2367 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2369 * utils.c (request_quit): Re-establish signal handler regardless
2372 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2374 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2376 * i960-tdep.c: Include target.h.
2378 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2380 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2382 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2384 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2385 changes (status -> ourstatus; declare status, etc.).
2386 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2388 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2390 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2392 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2394 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2396 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2398 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2400 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2402 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.

2406 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2407 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2409 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2412 Add search to target vector (#if 0'd until after 4.12):
2413 * target.h (to_search, target_search): Add.
2414 * gdbcore.h, core.c (generic_search): Add.
2415 * remote.c (remote_search): Add.
2416 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2419 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2420 is on, call find_pc_function rather than relying just on the minimal
2421 symbols (probably only matters for symbol readers which don't put
2422 statics in the minimal symbols, but changing this strikes me as
2423 not conservative enough).
2424 Initialize name_location in all cases.
2425 If no symbol and no msymbol, don't print anything symbolic.
2427 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2429 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2431 * printcmd.c (print_address_symbolic): Make it search the
2432 symtabs for variables as well as functions. Add `set print
2433 fast-symbolic-addr' and default it to fast (the old way).
2434 Print line numbers for data items as well as functions.
2436 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2437 address, if a symbol is found (take two more args pointing to
2438 where to store these results).
2440 * symtab.h (find_addr_symbol): Add prototype.
2442 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2444 * objfiles.h: Fix comments to reflect the fact that the phrase
2445 "top of stack" always refers to where the pushing and popping takes
2446 place, regardless of whether it is at the highest or lowest address.
2448 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2450 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2451 compiler generated tag names.
2452 * mdebugread.c (parse_type): Handle cross references to qualified
2454 * valops.c (value_struct_elt): Improve error message if the
2455 address of a method is requested from an object instance.
2456 * valops.c (search_struct_method): Make name_matched non-static
2457 to get it initialized correctly.
2458 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
2459 exclude segment register which are not writable on newer SCO versions.
2461 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2463 * go32-xdep.c: Remove unused function uerror.
2464 (sigsetmask): Declare return type. Declare argument (to match the
2465 way it is called). Explicitly return 0.
2467 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
2469 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
2470 partial_symbol): Shrink the storage sizes of symbols, by making
2471 enums into 1-byte bitfields when compiled __GNUC__, moving all the
2472 enums and small ints to the end of each struct to improve
2473 alignment, and switching the section number from int to unsigned
2476 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
2478 * symtab.c (find_addr_symbol): New routine that will find the nearest
2479 symbol associated with an address. It does so by exhaustive
2480 search of the symtabs, so it's slow but complete.
2482 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
2484 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
2485 to [0,0] rather than [0, end of first source file]. This avoids
2486 problems with other parts of GDB looking for linetables in the
2487 _globals_ symtab. Eliminate variables num_object_files and
2488 first_object_file_end.
2490 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2492 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
2493 (pop_frame): Restore PC2 and LR0 from dummy frames.
2494 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
2495 (setup_arbitrary_frame): Handle 3 args and set up real frames.
2496 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
2497 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
2498 (SETUP_ARBITRARY_FRAME): Define.
2500 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2502 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
2504 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2506 * remote-udi.c (udi_resume): Correct prototype.
2508 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2510 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
2511 hppa_frame_find_saved_regs.
2512 * hppa-tdep.c (dig_fp_from_stack): Delete function.
2513 (prologue_inst_adjust_sp): New function.
2514 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
2515 (skip_prologue): Completely rewrite to use unwind information.
2516 (hppa_frame_find_saved_regs): Likewise.
2518 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2520 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
2521 to convert a signal number with appropriate bounds checking.
2523 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
2525 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2527 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
2528 print a newline to end the display anyway.
2530 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
2531 coprocessor status regs) when popping a frame. This fixes
2532 float exceptions that occur after calling inferior functions.
2534 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2535 Read and write the fsr (float status register) to/from the child
2536 process along with the float regs. Remove Peter Schauer's change
2537 of May 24 '93, which has higher overhead and doesn't solve the
2538 real problem (which was that FSR wasn't being set).
2540 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
2542 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
2543 stack overflow check isn't right after the register stack
2544 adjustment instruction. Metaware R2.3u compiler moves other
2545 things in front of it. This fix isn't perfect but is what's
2548 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2550 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
2552 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
2553 character filenames.
2554 * configure.in: Change accordingly.
2556 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
2558 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
2559 _filtered io routines from these two files.
2561 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2563 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
2564 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
2565 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
2567 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
2569 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2571 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
2572 printing to gdb_stderr.
2574 * remote-udi.c (udi_kill): Don't close the connection, just set
2575 inferior_pid to zero.
2576 (udi_mourn): Call remove_breakpoints.
2578 * remote-udi.c: Remove obsolete need_artificial_traps comment.
2580 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
2582 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2584 * symtab.c (lookup_symbol): Don't try adding .c to the name.
2586 * remote-bug.c: At the start of each section, reset srec_frame
2589 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
2590 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
2591 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
2592 code which looks for those two waitkinds. Use switch statement.
2593 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
2594 CHILD_SPECIAL_WAITSTATUS.
2596 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
2597 * Move target_signal_from_host, target_signal_to_host, and
2598 store_waitstatus from inftarg.c to target.c. procfs needs them.
2599 * target.c: Include "wait.h" and <signal.h>.
2600 * target.h, infrun.c (proceed), proceed callers: Pass new code
2601 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
2602 enums being treated as unsigned and is cleaner.
2603 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
2605 * infcmd.c (signal_command), infrun.c (signals_info):
2606 Don't allow user to specify numeric equivalent of
2607 TARGET_SIGNAL_DEFAULT.
2609 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
2611 * config/alpha/alpha-netware.mt: New target support for Alpha
2613 * configure.in: Add alpha-*-netware* target.

2617 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
2619 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2621 * target.h: Add enum target_waitkind, enum target_signal, and
2622 struct target_waitstatus. Change status argument to target_wait to
2623 be struct target_waitstatus * instead of int *.
2624 * target.h, infrun.c, all targets: Change type of signal arguments
2625 to resume(), proceed(), and target_resume() from int to enum
2627 * All targets (*_wait, *_resume): Change accordingly.
2628 * infcmd.c (program_info, signal_command), throughout infrun.c,
2629 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
2630 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
2631 signal code stuff right with the new signals would be non-trivial).
2632 * inferior.h (stop_signal): Make it enum target_signal not int.
2633 * target.c, target.h (target_signal_to_string, target_signal_to_name,
2634 target_signal_from_name): New functions.
2635 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
2636 store_waitstatus): New functions.
2637 * procfs.c (procfs_notice_signals): Use them.
2638 * i960-tdep.c (i960_fault_to_signal): New function, to replace
2640 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
2642 * objfiles.c (build_objfile_section_table): Don't abort() if
2643 objfile->sections is already set.
2645 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
2646 to match recent change to exec.c.
2650 * main.c (print_gdb_version): Change year to 1994.
2652 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
2653 * Makefile.in (NONSRC): Add ChangeLog-93.
2655 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2657 * stabsread.c (read_type): Allow defining several type numbers
2658 at once (e.g. "(1,2)=(3,4)="...).
2660 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
2662 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
2664 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2666 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
2667 to process_one_symbol.
2668 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
2669 avoid caching a bad endaddr in find_pc_partial_function.
2671 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2673 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
2675 Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2677 * infrun.c (wait_for_inferior): Do not step or step resume past
2678 the end of a one-line function we just stepped into.
2680 For older changes see ChangeLog-93
2686 version-control: never
