1402 * buildsym.c (start_subfile, patch_subfile_names), demangle.c
1403 (set_demangling_style, set_demangling_command): Use savestring not

1420 * hppa-tdep.c (skip_prologue): Do nothing if not at the beginning
1422 (skip_trampoline_code): Rewrite and add support for argument

1437 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
1438 registers as both single and double values (fetching 2nd 32bit half
1439 as necessary). Annotate each register printed with its precision.
1441 * paread.c (read_unwind_info): Fix off-by-one error.

1449 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
1450 regarding using the PC--using the PC is necessary and all the
1451 FIXME comments in the world won't make it go away.
1453 * valops.c (value_at, value_at_lazy): Give error if we dereference
1455 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
1456 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
1458 * stabsread.c (patch_block_stabs): Add comment about what happens
1459 if the definition is in another compilation unit from the stab.

1465 * main.c (complete_command): New command, from Rick Sladkey
1466 <jrs@world.std.com>.
1467 (symbol_completion_function): Don't declare rl_point and
1468 rl_line_buffer; they are now declared in readline.h.
1469 (show_commands): Don't declare history_base; it is declared in
1471 * command.c (lookup_cmd): Don't delete trailing whitespace.
1472 Reverts change of 14 May 1989.
1474 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
1476 * minsyms.c (prim_record_minimal_symbol): Move section deduction
1477 code from prim_record_minimal_symbol_and_info() to here. Callers
1478 of the latter can legitimately supply a section number of -1.
1480 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1482 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
1483 member functions have an element in args for a (nonexistent) this
1486 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1488 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.

1494 for the structure's type. All callers changed.
1496 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
1497 for each structure argument rather than assuming it's either
1498 true or false for all structure arguments.
1500 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
1501 on the length structure passed, not the compiler used.
1503 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
1504 argument for the structure's type.
1506 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

1517 consistency of psymtabs and symtabs.
1518 * symtab.h (maintenance_check_symtabs): Add prototype.
1519 * maint.c: Add new `maint check-symtabs' command.
1520 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
1521 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.

1536 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1538 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1539 improve remote debugging efficiency. Also fixed problems with
1540 doing function calls for programs with no entry points.
1541 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1542 entry_point_address.
1543 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1544 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1545 parse_lines): Pass section_offsets info to these routines so that
1546 we can relocate symbol table entries upon readin.
1547 * (psymtab_to_symtab_1): Set symtab->primary to tell
1548 objfile_relocate to do relocations for our symbols.
1549 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1550 (which hang off of the symbol table).
1551 * Use prim_record_minimal_symbols_and_info instead of
1552 prim_record_minimal_symbols to supply section info to make minimal
1553 symbol relocations work.
1554 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1555 -1, try to deduce it from ms_type.
1556 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1557 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1558 add code to relocate objfile->sections data structure.
1559 * remote.c (get_offsets): Use new protocol message to acquire
1560 section offsets from the target.
1561 * (remote_wait): Get rid of relocation stuff. That's all handled
1562 by objfile_relocate now.
1563 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1564 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1566 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1568 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1570 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1572 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1573 can no longer set this at run time.
1574 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1575 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1576 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1577 sparc-tdep.c compiles).
1578 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1580 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1582 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1583 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1584 * configure.in: Recognize m68*-cisco*-*.
1586 * Makefile.in (TAGS): Use variables directly, rather than using
1587 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1588 and means that these filenames no longer need be unique across all
1589 the config/* directories.
1590 * configure.in: Put the config/*/ into TM_FILE, etc.
1592 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1593 and trapv exceptions.
1595 * target.h (struct section_table), objfiles.h (struct obj_section):
1596 Change name of field sec_ptr to the_bfd_section. More mnemonic
1597 and avoids the (sort of, for the ptx compiler) name clash with
1598 the name of the typedef.
1599 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1600 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1602 * utils.c: Include readline.h.
1603 * Makefile.in (utils.o): Add dependency.
1605 * remote.c (getpkt): Add support for run-length encoding.
1607 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1609 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1611 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1613 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1614 prim_record_minimal_symbol.
1617 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1618 computing their offset from the start of the old buffer and adding
1619 to the new buffer, rather than by assuming we can add the
1620 difference between the old buffer and the new buffer (it might not
1621 fit in an int). Merge in cosmetic differences from emacs regex.c
1622 version of this macro.
1624 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1626 * Makefile.in (install-only): Fix use of program_transform_name.

1630 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1631 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1632 so I'm nuking the command.
1633 * symtab.c (find_addr_symbol): Comment out, no longer used.
1635 * main.c (main): Don't init_source_path for the -cd argument. Now
1636 that source_path doesn't contain the current_directory from when
1637 GDB started up, init_source_path is no longer useful (and is
1638 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1640 * TODO: Remove item about line numbers being off. It is useless
1641 and confusing without a reproducible test case (it mentions
1642 proceed(), but I was able to step through proceed without trouble).
1644 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1646 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1647 library functions before the executable is run. Retrieve dynamic
1648 symbols from stripped executables.
1649 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1650 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1651 symtab.c (list_symbols): Handle mst_solib_trampoline.
1652 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1653 for all targets, remove IBM6000_TARGET dependencies.
1654 * dbxread.c (read_dbx_dynamic_symtab): New function.
1655 * dbxread.c (dbx_symfile_read): Use it.
1656 * dbxread.c (SET_NAMESTRING): Set namestring to
1657 "<bad string table index>" instead of "foo" if the string index is
1659 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1661 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1662 to break_command. Handle mst_file_* minimal symbol types.
1663 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1665 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1667 * c-exp.y(yylex): fix potential memory overflow.
1669 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1671 * environ.c (set_in_environ): Eliminate special handling of PATH and
1673 * putenv.c: Removed, conflicts with system declaration of
1674 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1676 * Makefile.in: Change accordingly.
1677 * procfs.c (procfs_create_inferior): Change comment accordingly.
1679 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1681 * rs6000-tdep.c: Change value to value_ptr.
1683 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1685 * i386m3-nat.c: Include floatformat.h.
1686 (get_i387_state): Use memset not bzero.
1690 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1691 ieee-float.h to floatformat.h.
1693 * valprint.c (val_print_string): Ignore error if the error
1694 happened after a terminating '\0'.
1696 * c-valprint.c (c_val_print): Never add 1 to return value from
1697 val_print_string; just return what it returns.
1699 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1700 looping through all of the enums.
1701 * infrun.c (signals_info): Use it.
1703 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1705 * main.c (main): When printing warning about bad baud rate, don't
1706 use warning(); it relies on current_target which isn't set up yet.
1708 * breakpoint.c (_initialize_breakpoint): Update docstring for
1709 tbreak to match what the code actually does. Don't mention tbreak
1710 in docstrings for "enable once" or "enable breakpoints once".
1712 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1714 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1715 while (0). That defeats the whole purpose of using do . . . while (0).
1716 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1717 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1718 using a ?: expression as an lvalue is not portable.
1720 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1721 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1722 'p' and 'r' symbol descriptors into a single symbol to look for a
1724 * README, config/sparc/tm-sparc.h: Update comments.
1726 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1728 * mdebugread.c (parse_type): Do not complain for types with
1729 an `indexNil' aux index, these are simply undefined types.
1730 Remove indexNil check from caller of parse_type.
1731 * mdebugread.c (parse_partial_symbols): Do not enter
1732 stGlobal, scCommon symbols into the minimal symbol table, their
1733 value is the size of the common, not its address.
1734 Handle scInit, scFini, scPData and scXData sections.
1735 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1737 Enter stProc symbols into the global_psymbols list once, not into
1738 the static_psymbols_list.
1739 Get rid of dummy psymtab if it is empty, to allow proper detection
1740 of stripped executables.
1741 * mdebugread.c (cross_ref): Allow cross references to Fortran
1744 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1746 * stabsread.c (common_block_end, fix_common_block): Stash the
1747 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1748 as to not assume that a pointer fits in an enum.
1750 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1752 * os9kread.c (fill_sym): check compiler verion number for pre-
1754 * os9kread.c (os9k_process_one_symbol): address of symbol is
1755 relative to section not module.
1756 * stabsread.c (define_symbol): add symbol type 's' as local
1758 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1760 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1761 * remote-os9k.c: fix bug in 'set remotebaud' function.
1762 * remote-os9k.c (rombug_link): minimize checking so to improve
1764 * symfile.c (symbol_file_command): check if failed to link, also make
1765 the command be able to accept more than one filenames.
1766 * target.c (target_link): check if failed to link with rombug.
1767 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1769 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1771 * remote-es.c (es1800_child_ops): Don't declare it static.

1779 * dbxread.c: New variable lowest_text_address.
1780 (record_minimal_symbol, read_dbx_symtab): Set it.
1781 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1782 end_of_text_address.
1783 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1785 * dbxread.c (end_psymtab): Remove old and commented out
1786 capping_global and capping_static. Fix comments regarding
1787 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1789 * parser-defs.h: Add "extern" to start of variable declarations so
1790 we don't end up with commons.
1791 * parse.c: Define these variables.
1793 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
1796 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

1800 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1802 * solib.c (elf_locate_base): New function to locate the address
1803 of the dynamic linker's runtime structure in the dynamic info section.
1804 * solib.c (locate_base): Use it instead of iterating over the list

1975 When looking for '\0', don't increment bufptr and addr if bufptr
1976 started out already at limit. If an error happens on fetching the
1977 first character, don't print the string.

2020 which performs one (the check_sigtramp2 one) of the functions
2021 which had been handled by the step_resume_breakpoint. For each
2022 use of the step_resume_breakpoint, make it still use the
2023 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
2025 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
2026 When setting the frame address of the step resume breakpoint, set
2027 it to the address for frame *before* the call instruction is
2028 executed, not after.

2034 read_register and then putting it back in target format with

2038 #if 0 unused include of opcode/mips.h.
2040 * symfile.h: Don't declare arguments for coff_getfilename.
2042 * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

2103 access & cache stuff) to use new ASI access macros in sparclite.h.
2104 Also make it easy to access second serial port.

2249 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
2250 rather than trying to shove an int into a pointer and back out
2251 again. This avoids compiler warnings.
2253 * defs.h (alloca): Declare as void *, not char *, on hpux.
2254 Don't prototype it, just declare the return type.
2256 Sun Feb 6 03:25:41 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2258 * config/i386/tm-sun386.h, config/i386/tm-symmetry.h
2259 (REGISTER_CONVERT_TO_RAW): Add missing backslash.
2261 Sat Feb 5 08:03:41 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2263 * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
2264 ZERO_REGNUM, just read it as zero without talking to the board.
2266 * config/i386/tm-i386aix.h (REGISTER_CONVERT_TO_RAW): Add missing
2268 * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
2269 to store_floating, not nonexistent variable len.
2271 * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
2273 (mips_store_word): Change calling convention to return errors, and
2274 to provide old contents if the caller wants it.
2275 (mips_xfer_memory): Deal with errors from mips_store_word.
2276 * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
2277 define now that remote-mips.c doesn't use BREAKPOINT.
2279 * remote-mips.c (mips_create_inferior): Call warning if arguments
2280 specified, and then execute "set args" command. Call error, not
2281 mips_error, if executable file not specified.
2283 * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
2286 * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
2289 Sat Feb 5 05:27:05 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2291 * value.h (print_longest): Rename "value" to "val" in prototype
2292 declaration because some compilers don't like arguments whose
2293 names are the same as types.
2294 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
2295 before passing it to remote_*_bytes.
2297 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
2299 * h8500-tdep.c (saved_pc_after_call): The size of the
2300 pc is memory model dependent. (segmented_command,
2301 unsegmented_command, _initialize_h8500_tdep): New commands to
2302 change memory model.
2303 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
2305 * remote-hms.c (hms_load): Remove breakpoints when loaded.
2306 (hms_wait): Use new status structure
2307 (hms_open): Push the target here. (hms_before_main_loop): Not
2308 here. (supply_val, hms_fetch_register, hms_store_register): Cope
2309 with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
2310 * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
2311 all registers in a compact way.
2313 Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2315 * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
2316 as CORE_ADDR to match definition in rs6000-tdep.c.
2318 Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2320 * dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
2321 * dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
2322 definitions into the psymtab.
2324 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2326 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
2327 a special exceptionSize for the 68332.
2329 * remote-udi.c (udi_attach): If no arguments, print error.
2331 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
2333 * Makefile.in (VERSION): Bump to 4.12.1
2334 * NEWS, README: Update to match 4.12 release.
2336 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2338 * command.c (empty_sfunc): New function.
2339 (add_set_cmd): Use it instead of not_just_help_class_command.
2340 (not_just_help_class_command): Change calling convention back to
2341 what it was before yesterday's change.
2343 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
2344 of the type if present.
2346 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2348 * printcmd.c (decode_format): Don't blithely set the size for
2349 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
2351 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
2352 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
2353 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
2354 always just check against INT_MIN and INT_MAX (this also fixes things
2355 if sizeof (long) > sizeof (int), e.g. Alpha).
2356 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
2357 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
2358 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
2359 BUILTIN_TYPE_UNSIGNED_LONGEST.
2360 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
2361 longest_int and longest_unsigned_int.
2362 * value.h (struct value): Just align to LONGEST, rather than worrying
2363 about CC_HAS_LONG_LONG.
2364 * valarith.c (value_binop): Figure out type ourself based on
2365 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
2366 point is that we don't depend on CC_HAS_LONG_LONG anymore.
2367 * valprint.c (val_print_type_code_int): Just call
2368 extract_unsigned_integer directly, rather than going through
2370 * printcmd.c (decode_format): Remove code which would sometimes
2371 change 'g' size to 'w' for integers. print_scalar_formatted handles
2372 printing huge integers well enough, thank you.
2374 * command.c (add_set_cmd, not_just_help_class_command): Change
2375 to make this the sfunc, not cfunc, since that is how we call it.
2376 * command.h: Comment difference between sfunc and cfunc.
2377 * demangle.c (set_demangling_command): Add third arg since that
2378 is how it is called.
2379 (_initialize_demangler): Use sfunc, not cfunc, for
2380 set_demangling_command, since that is how it is called.
2381 Remove show_demangling_command; it has no effect.
2383 * command.c (shell_escape): Report errors correctly (with error
2384 message from strerror).
2386 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2388 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
2389 x_scnlen.l rather than x_scnlen to match corresponding change in
2392 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2394 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
2395 Change comments regarding TYPE_CODE_BOOL.
2396 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
2397 regardless of the language.
2398 (value_true): Just call value_logical_not regardless of language.
2399 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
2400 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
2401 * language.h: Improve comment for la_builtin_type_vector.
2402 * m2-lang.c (_initialize_m2_language): Don't add any fields to
2403 builtin_type_m2_bool.
2405 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
2407 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
2408 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
2410 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2412 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
2413 by restarting the ioctl.
2415 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2417 * target.h (target_wait): Add comment about calling
2418 return_to_top_level.
2420 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2422 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
2423 additional arguments.
2424 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
2426 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
2428 * sparc-stub.c: Remove unnecessary #include of memory.h.
2430 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2432 * mips-tdep.c: Remove code which sets saved_regs from
2433 init_extra_frame_info and put it in new function mips_find_saved_regs.
2434 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
2435 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
2436 check if it is NULL and call mips_find_saved_regs if so.
2438 * remote-mips.c: Use unfiltered, not filtered, output most places.
2440 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
2441 backtrace. Revise comments.
2443 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2445 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
2446 alpha and irix. The _sigtramp case has to be handled properly
2447 in the tdep files if we have no ecoff debugging info.
2448 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
2449 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
2450 without PC_REGNUM kludge.
2451 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
2452 Clean up handling of mips sigtramp frames, improve comments.
2454 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2456 * paread.c (read_unwind_info): Fix typo.
2458 * paread.c (pa_symtab_read): Update the "check_strange_names"
2459 filter to match GCC's current output. Filter out section symbols
2460 (which the HP linker sometimes puts in the wrong place).
2462 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2464 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
2466 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
2468 * Makefile.in: Remove all references to sparcly-nat.c.
2470 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
2471 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
2472 duplicating serial.h and target.h.
2474 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
2475 are not used anywhere (a 5 Oct 1993 change removed the uses).
2477 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
2478 * config/m68k/es1800.mt: Add comment.
2479 * remote-es.c: Extensive changes to update to current conventions.
2481 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
2482 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
2483 to achieve the desired timeout.
2484 * serial.h (serial_t): Add field timeout_remaining.
2486 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2488 * c-exp.y (yylex): Reenable nested type code.
2490 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2492 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
2494 * remote-mips.c (mips_ops): Fix docstring.
2496 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
2498 * config/m68k/tm-monitor.h: Changes to bring this into accordance
2499 with the old tm-m68k-em.h:
2500 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
2501 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
2502 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
2503 Add FIXME regarding GET_LONGJMP_TARGET.
2505 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
2506 * infptrace.c (kill_inferior): Add comments.
2507 * main.c (quit_command): Call target_close after we kill or
2509 * remote-udi.c (udi_close): Don't error() if QUITTING.
2511 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
2513 * configure.in: Make m68k-coff and aout add monitor support in
2514 addition to the standard serial support.
2516 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2518 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
2521 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2523 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
2524 * elfread.c (record_minimal_symbol_and_info),
2525 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
2527 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2529 * i386-stub.c: Add ".text" right before "mem_fault:".
2531 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2533 * remote-utils.c (usage): Fix message to be accurate and conform
2534 more closely to normal conventions.
2536 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2537 whether to show information about exec_bfd, and not control whether
2538 to show information about device and speed.
2540 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2541 usage message, don't dump core.
2543 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2544 for variable size array.
2545 (bug_fetch_register, bug_store_register): Rename "value" to
2546 "fpreg_buf" because some compilers don't like variables whose
2547 names are the same as types.
2548 (bug_store_register): Use a cast when converting char * to
2551 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2552 of the command in error message (the text was referring to the old
2553 name of the command).
2555 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2557 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2558 full details on structure elements without names. This partially
2559 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2560 of those changes was accidental.
2562 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2563 defined, make it an error to specify a single argument which is not
2566 * Makefile.in (version.c), main.c (print_gdb_version): Use
2567 host_alias and target_alias, not host_canonical and
2568 target_canonical, to print configuration.
2570 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2572 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2573 of builtin_type_long. It is necessary to get a type which is
2574 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2576 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2577 various miscellaneous things discovered in the process:
2578 * printcmd.c, defs.h (print_address_numeric): New function.
2579 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2580 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2581 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2582 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2584 * utils.c, defs.h (gdb_print_address): New function.
2585 * expprint (dump_expression), gdbtypes.h: Use it.
2586 * breakpoint.c (describe_other_breakpoints),
2587 symmisc.c (dump_symtab, print_symbol):
2588 Use filtered not unfiltered I/O.
2589 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2590 just run gdb under a debugger for this (and it had problems with
2591 printing addresses, how to print b->shadow, etc.).
2592 * buildsym.c (make_blockvector), core.c (memory_error),
2593 exec.c (print_section_info), maint.c (print_section_table),
2594 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2595 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2596 Add comments saying code is broken. Marked with "FIXME-32x64".
2597 * dbxread.c (process_one_symbol), partial-stab.h (default),
2598 remote-vx.c (vx_run_files_info):
2599 Don't cast int being passed to local_hex_string.
2600 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2601 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2603 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2605 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2606 * source.c: Include <sys/types.h> regardless of USG.
2608 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2610 * valops.c (value_assign): Set `type' after coercing toval.
2611 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2612 Use extract_unsigned_integer to get the address of a reference.
2614 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2616 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2617 AIX can use ? instead of \ for continuation. Deal with it.
2619 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2620 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2621 the HP compiler in ANSI mode doesn't like.
2623 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2624 based on USG, rather than defining HAVE_SIGSETMASK to an
2625 expression containing defined. Having a macro used in #if expand
2626 to an expression containing "defined" is undefined according to
2627 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2630 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2632 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2633 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2635 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2637 * ch-exp.y (match_string_literal): Allow a zero-length string.
2638 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2640 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2642 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2643 passing them to print_387_status.
2644 (print_387_status): Don't subtract top from 7 before using it.
2645 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2646 from 7; the above explains it.
2648 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2650 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2651 pointer value when fixing up the frame at the start of a function.
2653 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2655 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2656 Sparc from the stack.
2658 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2660 * remote-mips.c (mips_initialize): Clear mips_initializing via
2661 cleanup chain, not directly.
2663 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2664 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2665 munging the timeout due to the limited range of c_cc[VTIME].
2667 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2668 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2669 m3-nat.c (m3_create_inferior): Pass it.
2670 * procfs.c: Remove ptrace function. It was declared in a way which
2671 conflicted with the prototype in unistd.h on Solaris.
2673 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2675 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2676 in the sigcontext if it is a signal trampoline frame.
2677 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
2678 Define for Solaris2.
2680 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2682 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2683 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2684 tm-sparc.h so they can be overridden if necessary.
2686 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2688 * lynx-nat.c: Add Sparc support.
2689 * sparcly-nat.c: Remove. It's useless.
2690 * config/sparc/nm-sparclynx.h: Rewrite.
2691 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2693 * config/sparc/tm-sparclynx.h: Rewrite.
2695 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2697 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2698 directory. Old code was discarded, since the new opcode table has
2701 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
2703 * Makefile.in (realclean): Remove info files per make-stds.texi.
2705 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2707 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2708 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2709 * config/sparc/tm-sun4sol2.h: Define it.
2711 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2713 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
2714 if we did not find a symbol.

2721 * hppab-nat.c (call_ptrace): Delete redundant function.
2722 (kill_inferior, attach, detach, child_resume): Likewise.
2723 (child_xfer_memory): Likewise.
2725 * hppah-nat.c (call_ptrace): Delete redundant function.
2726 (kill_inferior, attach, detach, child_resume): Likewise.
2728 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2730 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2732 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2734 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2735 (CHILD_XFER_MEMORY): Define.
2736 (PT_*): Define so that generic infptrace.c code can be used.
2738 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2740 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2741 struct section_offsets *, not a (nonexistent) struct section_offset *.
2743 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2744 internal_xcoff_symtab, not an array of one of them. Change lots of
2745 "main_aux" to "&main_aux" and so on.
2747 * coffread.c, xcoffread.c: Include <coff/internal.h>
2750 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2752 * coffread.c (coff_getfilename): Make it not static.
2754 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2756 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2757 a completely gratuitous difference between xcoffread.c and coffread.c).
2759 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2761 * infrun.c (wait_for_inferior): Don't set frame for
2762 step_resume_breakpoint for IN_SIGTRAMP cases.
2764 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2765 breakpoint.c (bpstat_what): Move step_resume from its own field of
2766 the struct bpstat_what into the main_action. Make it override
2767 other breakpoints. This is a conservative change in the sense
2768 that before the step resume breakpoint was a breakpoint.c
2769 breakpoint, hitting the step resume breakpoint overrode even
2770 calling bpstat_stop_status.
2772 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2774 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2775 in case execution was stopped in the called function.
2776 * stack.c (print_frame_info, frame_info): If backtracing through
2777 a call dummy, handle the starting source line number on a line
2778 boundary like backtracing through sigtramp.
2779 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2780 for call dummy frame right. Remove old test for dummy frame,
2781 it has been unused at least since gdb-3.5.
2782 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2785 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

2789 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2791 * infrun.c (signals_info), target.c (target_signal_from_name):
2792 Use ugly casts to avoid enumvar < enumvar or enumvar++.
2794 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2796 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
2797 * inflow.c (terminal_ours_1): When discussing how to deal with the
2798 tty state, make note of query() as well as readline.
2800 * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
2801 signals for which stop and print are cleared by default.
2803 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2805 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
2806 reserved fields to hold a stub unwind entry type. Fix typo.

2811 by linker stub unwind descriptors.
2812 (frameless_function_invocation): Likewise.
2813 (frame_chain_valid): Likewise.
2814 * paread.c (compare_unwind_entries): New function for sorting
2815 unwind table entries.
2816 (read_unwind_info): Rewrite to remove dependency on host endianness.
2817 Read in data from the $UNWIND_END$ subspace which contains linker
2818 stub unwind descriptors. Merge that data into the basic unwind
2821 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2823 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2825 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2826 from either the symbol name or the auxent.
2827 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2830 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2832 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2834 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2836 * README: Update notes for alpha port.
2838 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2840 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2841 for operation fault, constraint fault, and type fault.
2843 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2845 * Makefile.in (init.c): Add comment explaining formatting conventions.
2847 * c-exp.y (parse_number): Assign to temporary between the right
2848 shifts, to work around a bug in the SCO compiler.
2850 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2851 Add various files which were added to GDB recently.
2853 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
2856 * Makefile.in: Add mostlyclean target.
2858 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2862 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2864 * main.c (show_commands): Make return type of extern
2865 history_get be HIST_ENTRY, rather than struct _hist_entry.
2866 (The latter loses with the upcoming merged readline.)
2868 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2870 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2871 const char *, not char *.
2873 * symtab.h (struct symbol): Make section short, not unsigned short.
2875 * symtab.c (lookup_symbol): Add comment about QUIT here.
2877 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2879 * c-exp.y (parse_number): Check for overflow regardless of range
2880 checking. Fix overflow check to use unsigned LONGEST, not
2883 * c-exp.y (parse_number): Make it so that integer constants are
2884 builtin_type_long_long if builtin_type_long isn't big enough or if
2885 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2887 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2888 Print our "()" first, then recurse for the target type.
2890 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2892 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2894 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2896 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2898 * utils.c (request_quit): Re-establish signal handler regardless
2901 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2903 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2905 * i960-tdep.c: Include target.h.
2907 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2909 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2911 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2913 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2914 changes (status -> ourstatus; declare status, etc.).
2915 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2917 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2919 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2921 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2923 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2925 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2927 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2929 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2931 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
2933 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2935 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2936 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2938 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2941 Add search to target vector (#if 0'd until after 4.12):
2942 * target.h (to_search, target_search): Add.
2943 * gdbcore.h, core.c (generic_search): Add.
2944 * remote.c (remote_search): Add.
2945 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2948 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2949 is on, call find_pc_function rather than relying just on the minimal
2950 symbols (probably only matters for symbol readers which don't put
2951 statics in the minimal symbols, but changing this strikes me as
2952 not conservative enough).
2953 Initialize name_location in all cases.
2954 If no symbol and no msymbol, don't print anything symbolic.
2956 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2958 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2960 * printcmd.c (print_address_symbolic): Make it search the
2961 symtabs for variables as well as functions. Add `set print
2962 fast-symbolic-addr' and default it to fast (the old way).
2963 Print line numbers for data items as well as functions.
2965 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2966 address, if a symbol is found (take two more args pointing to
2967 where to store these results).
2969 * symtab.h (find_addr_symbol): Add prototype.
2971 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2973 * objfiles.h: Fix comments to reflect the fact that the phrase
2974 "top of stack" always refers to where the pushing and popping takes
2975 place, regardless of whether it is at the highest or lowest address.
2977 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2979 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2980 compiler generated tag names.
2981 * mdebugread.c (parse_type): Handle cross references to qualified
2983 * valops.c (value_struct_elt): Improve error message if the
2984 address of a method is requested from an object instance.
2985 * valops.c (search_struct_method): Make name_matched non-static
2986 to get it initialized correctly.
2987 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
2988 exclude segment register which are not writable on newer SCO versions.
2990 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2992 * go32-xdep.c: Remove unused function uerror.
2993 (sigsetmask): Declare return type. Declare argument (to match the
2994 way it is called). Explicitly return 0.
2996 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
2998 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
2999 partial_symbol): Shrink the storage sizes of symbols, by making
3000 enums into 1-byte bitfields when compiled __GNUC__, moving all the
3001 enums and small ints to the end of each struct to improve
3002 alignment, and switching the section number from int to unsigned
3005 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
3007 * symtab.c (find_addr_symbol): New routine that will find the nearest
3008 symbol associated with an address. It does so by exhaustive
3009 search of the symtabs, so it's slow but complete.
3011 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
3013 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
3014 to [0,0] rather than [0, end of first source file]. This avoids
3015 problems with other parts of GDB looking for linetables in the
3016 _globals_ symtab. Eliminate variables num_object_files and
3017 first_object_file_end.
3019 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3021 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
3022 (pop_frame): Restore PC2 and LR0 from dummy frames.
3023 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
3024 (setup_arbitrary_frame): Handle 3 args and set up real frames.
3025 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
3026 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
3027 (SETUP_ARBITRARY_FRAME): Define.
3029 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3031 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
3033 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3035 * remote-udi.c (udi_resume): Correct prototype.
3037 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3039 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
3040 hppa_frame_find_saved_regs.
3041 * hppa-tdep.c (dig_fp_from_stack): Delete function.
3042 (prologue_inst_adjust_sp): New function.
3043 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
3044 (skip_prologue): Completely rewrite to use unwind information.
3045 (hppa_frame_find_saved_regs): Likewise.
3047 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3049 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
3050 to convert a signal number with appropriate bounds checking.
3052 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
3054 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3056 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
3057 print a newline to end the display anyway.
3059 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
3060 coprocessor status regs) when popping a frame. This fixes
3061 float exceptions that occur after calling inferior functions.
3063 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
3064 Read and write the fsr (float status register) to/from the child
3065 process along with the float regs. Remove Peter Schauer's change
3066 of May 24 '93, which has higher overhead and doesn't solve the
3067 real problem (which was that FSR wasn't being set).
3069 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
3071 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
3072 stack overflow check isn't right after the register stack
3073 adjustment instruction. Metaware R2.3u compiler moves other
3074 things in front of it. This fix isn't perfect but is what's
3077 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3079 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
3081 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
3082 character filenames.
3083 * configure.in: Change accordingly.
3085 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
3087 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
3088 _filtered io routines from these two files.
3090 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3092 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
3093 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
3094 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
3096 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
3098 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3100 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
3101 printing to gdb_stderr.
3103 * remote-udi.c (udi_kill): Don't close the connection, just set
3104 inferior_pid to zero.
3105 (udi_mourn): Call remove_breakpoints.
3107 * remote-udi.c: Remove obsolete need_artificial_traps comment.
3109 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
3111 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3113 * symtab.c (lookup_symbol): Don't try adding .c to the name.
3115 * remote-bug.c: At the start of each section, reset srec_frame
3118 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
3119 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
3120 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
3121 code which looks for those two waitkinds. Use switch statement.
3122 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
3123 CHILD_SPECIAL_WAITSTATUS.
3125 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
3126 * Move target_signal_from_host, target_signal_to_host, and
3127 store_waitstatus from inftarg.c to target.c. procfs needs them.
3128 * target.c: Include "wait.h" and <signal.h>.
3129 * target.h, infrun.c (proceed), proceed callers: Pass new code
3130 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
3131 enums being treated as unsigned and is cleaner.
3132 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
3134 * infcmd.c (signal_command), infrun.c (signals_info):
3135 Don't allow user to specify numeric equivalent of
3136 TARGET_SIGNAL_DEFAULT.
3138 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
3140 * config/alpha/alpha-netware.mt: New target support for Alpha
3142 * configure.in: Add alpha-*-netware* target.
3144 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
3146 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
3148 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3150 * target.h: Add enum target_waitkind, enum target_signal, and
3151 struct target_waitstatus. Change status argument to target_wait to
3152 be struct target_waitstatus * instead of int *.
3153 * target.h, infrun.c, all targets: Change type of signal arguments
3154 to resume(), proceed(), and target_resume() from int to enum
3156 * All targets (*_wait, *_resume): Change accordingly.
3157 * infcmd.c (program_info, signal_command), throughout infrun.c,
3158 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
3159 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
3160 signal code stuff right with the new signals would be non-trivial).
3161 * inferior.h (stop_signal): Make it enum target_signal not int.
3162 * target.c, target.h (target_signal_to_string, target_signal_to_name,
3163 target_signal_from_name): New functions.
3164 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
3165 store_waitstatus): New functions.
3166 * procfs.c (procfs_notice_signals): Use them.
3167 * i960-tdep.c (i960_fault_to_signal): New function, to replace
3169 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
3171 * objfiles.c (build_objfile_section_table): Don't abort() if
3172 objfile->sections is already set.
3174 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
3175 to match recent change to exec.c.
3179 * main.c (print_gdb_version): Change year to 1994.
3181 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
3182 * Makefile.in (NONSRC): Add ChangeLog-93.
3184 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3186 * stabsread.c (read_type): Allow defining several type numbers
3187 at once (e.g. "(1,2)=(3,4)="...).
3189 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
3191 * breakpoint.c (frame_in_dummy): Check PC as well as frame.

3195 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
3196 to process_one_symbol.
3197 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
3198 avoid caching a bad endaddr in find_pc_partial_function.
3200 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3202 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.

3206 * infrun.c (wait_for_inferior): Do not step or step resume past
3207 the end of a one-line function we just stepped into.
