1406 space to the end of the string.
1407 * NEWS: Document this change.

1415 * buildsym.c (start_subfile, patch_subfile_names), demangle.c
1416 (set_demangling_style, set_demangling_command): Use savestring not

1431 Fri Mar 25 10:14:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1433 * hppa-tdep.c (skip_prologue): Do nothing if not at the beginning
1435 (skip_trampoline_code): Rewrite and add support for argument
1436 relocation stubs stubs, import/export stubs, calls through
1437 "_sr4export" and cascaded trampolines.

1440 if no unwind descriptor is found.
1442 * tm-hppa.h (NUM_REGS): Bump to 128 registers.
1443 (REGISTER_NAMES): Add entries for "right-half" of FP registers.
1444 (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs

1448 (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
1450 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
1451 registers as both single and double values (fetching 2nd 32bit half
1452 as necessary). Annotate each register printed with its precision.
1454 * paread.c (read_unwind_info): Fix off-by-one error.

1462 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
1463 regarding using the PC--using the PC is necessary and all the
1464 FIXME comments in the world won't make it go away.
1466 * valops.c (value_at, value_at_lazy): Give error if we dereference
1468 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
1469 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
1471 * stabsread.c (patch_block_stabs): Add comment about what happens
1472 if the definition is in another compilation unit from the stab.
1474 * dbxread.c (end_psymtab): Add comment about empty psymtabs.

1478 * main.c (complete_command): New command, from Rick Sladkey
1479 <jrs@world.std.com>.
1480 (symbol_completion_function): Don't declare rl_point and
1481 rl_line_buffer; they are now declared in readline.h.
1482 (show_commands): Don't declare history_base; it is declared in
1484 * command.c (lookup_cmd): Don't delete trailing whitespace.
1485 Reverts change of 14 May 1989.
1487 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
1489 * minsyms.c (prim_record_minimal_symbol): Move section deduction
1490 code from prim_record_minimal_symbol_and_info() to here. Callers
1491 of the latter can legitimately supply a section number of -1.
1493 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1495 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
1496 member functions have an element in args for a (nonexistent) this
1499 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1501 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.

1504 queue if NO_PC_SPACE_QUEUE_RESTORE is defined.
1506 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
1507 for the structure's type. All callers changed.
1509 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
1510 for each structure argument rather than assuming it's either
1511 true or false for all structure arguments.
1513 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
1514 on the length structure passed, not the compiler used.
1516 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
1517 argument for the structure's type.
1519 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1521 * values.c (set_internalvar): Don't set var->value until we are

1549 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1551 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1552 improve remote debugging efficiency. Also fixed problems with
1553 doing function calls for programs with no entry points.
1554 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1555 entry_point_address.
1556 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1557 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1558 parse_lines): Pass section_offsets info to these routines so that
1559 we can relocate symbol table entries upon readin.
1560 * (psymtab_to_symtab_1): Set symtab->primary to tell
1561 objfile_relocate to do relocations for our symbols.
1562 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1563 (which hang off of the symbol table).
1564 * Use prim_record_minimal_symbols_and_info instead of
1565 prim_record_minimal_symbols to supply section info to make minimal
1566 symbol relocations work.
1567 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1568 -1, try to deduce it from ms_type.
1569 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1570 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1571 add code to relocate objfile->sections data structure.
1572 * remote.c (get_offsets): Use new protocol message to acquire
1573 section offsets from the target.
1574 * (remote_wait): Get rid of relocation stuff. That's all handled
1575 by objfile_relocate now.
1576 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1577 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1579 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1581 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1583 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1585 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1586 can no longer set this at run time.
1587 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1588 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1589 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1590 sparc-tdep.c compiles).
1591 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1593 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1595 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1596 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1597 * configure.in: Recognize m68*-cisco*-*.
1599 * Makefile.in (TAGS): Use variables directly, rather than using
1600 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1601 and means that these filenames no longer need be unique across all
1602 the config/* directories.
1603 * configure.in: Put the config/*/ into TM_FILE, etc.
1605 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1606 and trapv exceptions.
1608 * target.h (struct section_table), objfiles.h (struct obj_section):
1609 Change name of field sec_ptr to the_bfd_section. More mnemonic
1610 and avoids the (sort of, for the ptx compiler) name clash with
1611 the name of the typedef.
1612 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1613 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1615 * utils.c: Include readline.h.
1616 * Makefile.in (utils.o): Add dependency.
1618 * remote.c (getpkt): Add support for run-length encoding.
1620 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1622 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1624 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1626 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1627 prim_record_minimal_symbol.
1630 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1631 computing their offset from the start of the old buffer and adding
1632 to the new buffer, rather than by assuming we can add the
1633 difference between the old buffer and the new buffer (it might not
1634 fit in an int). Merge in cosmetic differences from emacs regex.c
1635 version of this macro.
1637 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1639 * Makefile.in (install-only): Fix use of program_transform_name.
1641 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1643 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1644 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1645 so I'm nuking the command.
1646 * symtab.c (find_addr_symbol): Comment out, no longer used.
1648 * main.c (main): Don't init_source_path for the -cd argument. Now
1649 that source_path doesn't contain the current_directory from when
1650 GDB started up, init_source_path is no longer useful (and is
1651 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1653 * TODO: Remove item about line numbers being off. It is useless
1654 and confusing without a reproducible test case (it mentions
1655 proceed(), but I was able to step through proceed without trouble).
1657 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1659 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1660 library functions before the executable is run. Retrieve dynamic
1661 symbols from stripped executables.
1662 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1663 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1664 symtab.c (list_symbols): Handle mst_solib_trampoline.
1665 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1666 for all targets, remove IBM6000_TARGET dependencies.
1667 * dbxread.c (read_dbx_dynamic_symtab): New function.
1668 * dbxread.c (dbx_symfile_read): Use it.
1669 * dbxread.c (SET_NAMESTRING): Set namestring to
1670 "<bad string table index>" instead of "foo" if the string index is
1672 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1674 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1675 to break_command. Handle mst_file_* minimal symbol types.
1676 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1678 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1680 * c-exp.y(yylex): fix potential memory overflow.
1682 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1684 * environ.c (set_in_environ): Eliminate special handling of PATH and
1686 * putenv.c: Removed, conflicts with system declaration of
1687 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1689 * Makefile.in: Change accordingly.
1690 * procfs.c (procfs_create_inferior): Change comment accordingly.
1692 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1694 * rs6000-tdep.c: Change value to value_ptr.
1696 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1698 * i386m3-nat.c: Include floatformat.h.
1699 (get_i387_state): Use memset not bzero.
1703 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1704 ieee-float.h to floatformat.h.
1706 * valprint.c (val_print_string): Ignore error if the error
1707 happened after a terminating '\0'.
1709 * c-valprint.c (c_val_print): Never add 1 to return value from
1710 val_print_string; just return what it returns.
1712 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1713 looping through all of the enums.
1714 * infrun.c (signals_info): Use it.
1716 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1718 * main.c (main): When printing warning about bad baud rate, don't
1719 use warning(); it relies on current_target which isn't set up yet.
1721 * breakpoint.c (_initialize_breakpoint): Update docstring for
1722 tbreak to match what the code actually does. Don't mention tbreak
1723 in docstrings for "enable once" or "enable breakpoints once".
1725 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1727 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1728 while (0). That defeats the whole purpose of using do . . . while (0).
1729 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1730 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1731 using a ?: expression as an lvalue is not portable.
1733 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1734 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1735 'p' and 'r' symbol descriptors into a single symbol to look for a
1737 * README, config/sparc/tm-sparc.h: Update comments.
1739 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1741 * mdebugread.c (parse_type): Do not complain for types with
1742 an `indexNil' aux index, these are simply undefined types.
1743 Remove indexNil check from caller of parse_type.
1744 * mdebugread.c (parse_partial_symbols): Do not enter
1745 stGlobal, scCommon symbols into the minimal symbol table, their
1746 value is the size of the common, not its address.
1747 Handle scInit, scFini, scPData and scXData sections.
1748 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1750 Enter stProc symbols into the global_psymbols list once, not into
1751 the static_psymbols_list.
1752 Get rid of dummy psymtab if it is empty, to allow proper detection
1753 of stripped executables.
1754 * mdebugread.c (cross_ref): Allow cross references to Fortran
1757 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1759 * stabsread.c (common_block_end, fix_common_block): Stash the
1760 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1761 as to not assume that a pointer fits in an enum.
1763 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1765 * os9kread.c (fill_sym): check compiler verion number for pre-
1767 * os9kread.c (os9k_process_one_symbol): address of symbol is
1768 relative to section not module.
1769 * stabsread.c (define_symbol): add symbol type 's' as local
1771 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1773 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1774 * remote-os9k.c: fix bug in 'set remotebaud' function.
1775 * remote-os9k.c (rombug_link): minimize checking so to improve
1777 * symfile.c (symbol_file_command): check if failed to link, also make
1778 the command be able to accept more than one filenames.
1779 * target.c (target_link): check if failed to link with rombug.
1780 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1782 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1784 * remote-es.c (es1800_child_ops): Don't declare it static.

1792 * dbxread.c: New variable lowest_text_address.
1793 (record_minimal_symbol, read_dbx_symtab): Set it.
1794 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1795 end_of_text_address.
1796 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1798 * dbxread.c (end_psymtab): Remove old and commented out
1799 capping_global and capping_static. Fix comments regarding
1800 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1802 * parser-defs.h: Add "extern" to start of variable declarations so
1803 we don't end up with commons.
1804 * parse.c: Define these variables.
1806 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
1809 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1811 * alpha-tdep.c: Change value to value_ptr.
1813 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1815 * solib.c (elf_locate_base): New function to locate the address
1816 of the dynamic linker's runtime structure in the dynamic info section.
1817 * solib.c (locate_base): Use it instead of iterating over the list
1818 of mapped address segments.
1819 * solib.c (look_for_base, bfd_lookup_symbol): Removed, no longer
1822 Fri Mar 4 09:50:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1988 When looking for '\0', don't increment bufptr and addr if bufptr
1989 started out already at limit. If an error happens on fetching the
1990 first character, don't print the string.

2033 which performs one (the check_sigtramp2 one) of the functions
2034 which had been handled by the step_resume_breakpoint. For each
2035 use of the step_resume_breakpoint, make it still use the
2036 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
2038 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
2039 When setting the frame address of the step resume breakpoint, set
2040 it to the address for frame *before* the call instruction is
2041 executed, not after.

2047 read_register and then putting it back in target format with

2051 #if 0 unused include of opcode/mips.h.
2053 * symfile.h: Don't declare arguments for coff_getfilename.

2116 access & cache stuff) to use new ASI access macros in sparclite.h.
2117 Also make it easy to access second serial port.

2249 (m3_open): New function.
2251 * TODO: Update Mach section.
2253 * Makefile.in: Remove "rapp" stuff; it is superseded by gdbserver.
2255 Sun Feb 6 13:26:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
2257 * printcmd.c (printf_command): Add missing single-letter
2258 backslash-escape sequences, and improve error message.
2260 Sun Feb 6 06:55:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2262 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
2263 rather than trying to shove an int into a pointer and back out
2264 again. This avoids compiler warnings.
2266 * defs.h (alloca): Declare as void *, not char *, on hpux.
2267 Don't prototype it, just declare the return type.
2269 Sun Feb 6 03:25:41 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2271 * config/i386/tm-sun386.h, config/i386/tm-symmetry.h
2272 (REGISTER_CONVERT_TO_RAW): Add missing backslash.
2274 Sat Feb 5 08:03:41 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2276 * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
2277 ZERO_REGNUM, just read it as zero without talking to the board.
2279 * config/i386/tm-i386aix.h (REGISTER_CONVERT_TO_RAW): Add missing
2281 * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
2282 to store_floating, not nonexistent variable len.
2284 * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
2286 (mips_store_word): Change calling convention to return errors, and
2287 to provide old contents if the caller wants it.
2288 (mips_xfer_memory): Deal with errors from mips_store_word.
2289 * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
2290 define now that remote-mips.c doesn't use BREAKPOINT.
2292 * remote-mips.c (mips_create_inferior): Call warning if arguments
2293 specified, and then execute "set args" command. Call error, not
2294 mips_error, if executable file not specified.
2296 * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
2299 * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
2302 Sat Feb 5 05:27:05 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2304 * value.h (print_longest): Rename "value" to "val" in prototype
2305 declaration because some compilers don't like arguments whose
2306 names are the same as types.
2307 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
2308 before passing it to remote_*_bytes.
2310 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
2312 * h8500-tdep.c (saved_pc_after_call): The size of the
2313 pc is memory model dependent. (segmented_command,
2314 unsegmented_command, _initialize_h8500_tdep): New commands to
2315 change memory model.
2316 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
2318 * remote-hms.c (hms_load): Remove breakpoints when loaded.
2319 (hms_wait): Use new status structure
2320 (hms_open): Push the target here. (hms_before_main_loop): Not
2321 here. (supply_val, hms_fetch_register, hms_store_register): Cope
2322 with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
2323 * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
2324 all registers in a compact way.
2326 Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2328 * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
2329 as CORE_ADDR to match definition in rs6000-tdep.c.
2331 Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2333 * dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
2334 * dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
2335 definitions into the psymtab.
2337 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2339 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
2340 a special exceptionSize for the 68332.
2342 * remote-udi.c (udi_attach): If no arguments, print error.
2344 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
2346 * Makefile.in (VERSION): Bump to 4.12.1
2347 * NEWS, README: Update to match 4.12 release.
2349 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2351 * command.c (empty_sfunc): New function.
2352 (add_set_cmd): Use it instead of not_just_help_class_command.
2353 (not_just_help_class_command): Change calling convention back to
2354 what it was before yesterday's change.
2356 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
2357 of the type if present.
2359 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2361 * printcmd.c (decode_format): Don't blithely set the size for
2362 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
2364 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
2365 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
2366 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
2367 always just check against INT_MIN and INT_MAX (this also fixes things
2368 if sizeof (long) > sizeof (int), e.g. Alpha).
2369 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
2370 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
2371 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
2372 BUILTIN_TYPE_UNSIGNED_LONGEST.
2373 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
2374 longest_int and longest_unsigned_int.
2375 * value.h (struct value): Just align to LONGEST, rather than worrying
2376 about CC_HAS_LONG_LONG.
2377 * valarith.c (value_binop): Figure out type ourself based on
2378 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
2379 point is that we don't depend on CC_HAS_LONG_LONG anymore.
2380 * valprint.c (val_print_type_code_int): Just call
2381 extract_unsigned_integer directly, rather than going through
2383 * printcmd.c (decode_format): Remove code which would sometimes
2384 change 'g' size to 'w' for integers. print_scalar_formatted handles
2385 printing huge integers well enough, thank you.
2387 * command.c (add_set_cmd, not_just_help_class_command): Change
2388 to make this the sfunc, not cfunc, since that is how we call it.
2389 * command.h: Comment difference between sfunc and cfunc.
2390 * demangle.c (set_demangling_command): Add third arg since that
2391 is how it is called.
2392 (_initialize_demangler): Use sfunc, not cfunc, for
2393 set_demangling_command, since that is how it is called.
2394 Remove show_demangling_command; it has no effect.
2396 * command.c (shell_escape): Report errors correctly (with error
2397 message from strerror).
2399 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2401 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
2402 x_scnlen.l rather than x_scnlen to match corresponding change in
2405 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2407 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
2408 Change comments regarding TYPE_CODE_BOOL.
2409 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
2410 regardless of the language.
2411 (value_true): Just call value_logical_not regardless of language.
2412 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
2413 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
2414 * language.h: Improve comment for la_builtin_type_vector.
2415 * m2-lang.c (_initialize_m2_language): Don't add any fields to
2416 builtin_type_m2_bool.
2418 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
2420 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
2421 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
2423 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2425 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
2426 by restarting the ioctl.
2428 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2430 * target.h (target_wait): Add comment about calling
2431 return_to_top_level.
2433 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2435 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
2436 additional arguments.
2437 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
2439 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
2441 * sparc-stub.c: Remove unnecessary #include of memory.h.
2443 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2445 * mips-tdep.c: Remove code which sets saved_regs from
2446 init_extra_frame_info and put it in new function mips_find_saved_regs.
2447 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
2448 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
2449 check if it is NULL and call mips_find_saved_regs if so.
2451 * remote-mips.c: Use unfiltered, not filtered, output most places.
2453 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
2454 backtrace. Revise comments.
2456 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2458 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
2459 alpha and irix. The _sigtramp case has to be handled properly
2460 in the tdep files if we have no ecoff debugging info.
2461 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
2462 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
2463 without PC_REGNUM kludge.
2464 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
2465 Clean up handling of mips sigtramp frames, improve comments.
2467 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2469 * paread.c (read_unwind_info): Fix typo.
2471 * paread.c (pa_symtab_read): Update the "check_strange_names"
2472 filter to match GCC's current output. Filter out section symbols
2473 (which the HP linker sometimes puts in the wrong place).
2475 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2477 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
2479 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
2481 * Makefile.in: Remove all references to sparcly-nat.c.
2483 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
2484 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
2485 duplicating serial.h and target.h.
2487 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
2488 are not used anywhere (a 5 Oct 1993 change removed the uses).
2490 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
2491 * config/m68k/es1800.mt: Add comment.
2492 * remote-es.c: Extensive changes to update to current conventions.
2494 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
2495 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
2496 to achieve the desired timeout.
2497 * serial.h (serial_t): Add field timeout_remaining.
2499 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2501 * c-exp.y (yylex): Reenable nested type code.
2503 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2505 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
2507 * remote-mips.c (mips_ops): Fix docstring.
2509 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
2511 * config/m68k/tm-monitor.h: Changes to bring this into accordance
2512 with the old tm-m68k-em.h:
2513 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
2514 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
2515 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
2516 Add FIXME regarding GET_LONGJMP_TARGET.
2518 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
2519 * infptrace.c (kill_inferior): Add comments.
2520 * main.c (quit_command): Call target_close after we kill or
2522 * remote-udi.c (udi_close): Don't error() if QUITTING.
2524 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
2526 * configure.in: Make m68k-coff and aout add monitor support in
2527 addition to the standard serial support.
2529 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2531 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
2534 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2536 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
2537 * elfread.c (record_minimal_symbol_and_info),
2538 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
2540 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2542 * i386-stub.c: Add ".text" right before "mem_fault:".
2544 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2546 * remote-utils.c (usage): Fix message to be accurate and conform
2547 more closely to normal conventions.
2549 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2550 whether to show information about exec_bfd, and not control whether
2551 to show information about device and speed.
2553 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2554 usage message, don't dump core.
2556 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2557 for variable size array.
2558 (bug_fetch_register, bug_store_register): Rename "value" to
2559 "fpreg_buf" because some compilers don't like variables whose
2560 names are the same as types.
2561 (bug_store_register): Use a cast when converting char * to
2564 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2565 of the command in error message (the text was referring to the old
2566 name of the command).
2568 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2570 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2571 full details on structure elements without names. This partially
2572 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2573 of those changes was accidental.
2575 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2576 defined, make it an error to specify a single argument which is not
2579 * Makefile.in (version.c), main.c (print_gdb_version): Use
2580 host_alias and target_alias, not host_canonical and
2581 target_canonical, to print configuration.
2583 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2585 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2586 of builtin_type_long. It is necessary to get a type which is
2587 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2589 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2590 various miscellaneous things discovered in the process:
2591 * printcmd.c, defs.h (print_address_numeric): New function.
2592 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2593 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2594 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2595 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2597 * utils.c, defs.h (gdb_print_address): New function.
2598 * expprint (dump_expression), gdbtypes.h: Use it.
2599 * breakpoint.c (describe_other_breakpoints),
2600 symmisc.c (dump_symtab, print_symbol):
2601 Use filtered not unfiltered I/O.
2602 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2603 just run gdb under a debugger for this (and it had problems with
2604 printing addresses, how to print b->shadow, etc.).
2605 * buildsym.c (make_blockvector), core.c (memory_error),
2606 exec.c (print_section_info), maint.c (print_section_table),
2607 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2608 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2609 Add comments saying code is broken. Marked with "FIXME-32x64".
2610 * dbxread.c (process_one_symbol), partial-stab.h (default),
2611 remote-vx.c (vx_run_files_info):
2612 Don't cast int being passed to local_hex_string.
2613 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2614 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2616 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2618 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2619 * source.c: Include <sys/types.h> regardless of USG.
2621 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2623 * valops.c (value_assign): Set `type' after coercing toval.
2624 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2625 Use extract_unsigned_integer to get the address of a reference.
2627 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2629 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2630 AIX can use ? instead of \ for continuation. Deal with it.
2632 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2633 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2634 the HP compiler in ANSI mode doesn't like.
2636 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2637 based on USG, rather than defining HAVE_SIGSETMASK to an
2638 expression containing defined. Having a macro used in #if expand
2639 to an expression containing "defined" is undefined according to
2640 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2643 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2645 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2646 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2648 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2650 * ch-exp.y (match_string_literal): Allow a zero-length string.
2651 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2653 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2655 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2656 passing them to print_387_status.
2657 (print_387_status): Don't subtract top from 7 before using it.
2658 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2659 from 7; the above explains it.
2661 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2663 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2664 pointer value when fixing up the frame at the start of a function.
2666 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2668 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2669 Sparc from the stack.
2671 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2673 * remote-mips.c (mips_initialize): Clear mips_initializing via
2674 cleanup chain, not directly.
2676 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2677 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2678 munging the timeout due to the limited range of c_cc[VTIME].
2680 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2681 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2682 m3-nat.c (m3_create_inferior): Pass it.
2683 * procfs.c: Remove ptrace function. It was declared in a way which
2684 conflicted with the prototype in unistd.h on Solaris.
2686 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2688 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2689 in the sigcontext if it is a signal trampoline frame.
2690 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
2691 Define for Solaris2.
2693 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2695 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2696 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2697 tm-sparc.h so they can be overridden if necessary.
2699 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2701 * lynx-nat.c: Add Sparc support.
2702 * sparcly-nat.c: Remove. It's useless.
2703 * config/sparc/nm-sparclynx.h: Rewrite.
2704 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2706 * config/sparc/tm-sparclynx.h: Rewrite.
2708 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2710 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2711 directory. Old code was discarded, since the new opcode table has
2714 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
2716 * Makefile.in (realclean): Remove info files per make-stds.texi.
2718 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2720 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2721 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2722 * config/sparc/tm-sun4sol2.h: Define it.
2724 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2726 * printcmd.c (print_address_symbolic): Unconditionally use msymbol

2736 (child_xfer_memory): Likewise.
2738 * hppah-nat.c (call_ptrace): Delete redundant function.
2739 (kill_inferior, attach, detach, child_resume): Likewise.
2741 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2743 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2745 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2747 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2748 (CHILD_XFER_MEMORY): Define.
2749 (PT_*): Define so that generic infptrace.c code can be used.
2751 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2753 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2754 struct section_offsets *, not a (nonexistent) struct section_offset *.
2756 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2757 internal_xcoff_symtab, not an array of one of them. Change lots of
2758 "main_aux" to "&main_aux" and so on.
2760 * coffread.c, xcoffread.c: Include <coff/internal.h>
2763 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2765 * coffread.c (coff_getfilename): Make it not static.
2767 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2769 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2770 a completely gratuitous difference between xcoffread.c and coffread.c).
2772 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2774 * infrun.c (wait_for_inferior): Don't set frame for
2775 step_resume_breakpoint for IN_SIGTRAMP cases.
2777 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2778 breakpoint.c (bpstat_what): Move step_resume from its own field of
2779 the struct bpstat_what into the main_action. Make it override
2780 other breakpoints. This is a conservative change in the sense
2781 that before the step resume breakpoint was a breakpoint.c
2782 breakpoint, hitting the step resume breakpoint overrode even
2783 calling bpstat_stop_status.
2785 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2787 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2788 in case execution was stopped in the called function.
2789 * stack.c (print_frame_info, frame_info): If backtracing through
2790 a call dummy, handle the starting source line number on a line
2791 boundary like backtracing through sigtramp.
2792 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2793 for call dummy frame right. Remove old test for dummy frame,
2794 it has been unused at least since gdb-3.5.
2795 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2798 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

2802 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2804 * infrun.c (signals_info), target.c (target_signal_from_name):
2805 Use ugly casts to avoid enumvar < enumvar or enumvar++.
2807 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2809 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
2810 * inflow.c (terminal_ours_1): When discussing how to deal with the
2811 tty state, make note of query() as well as readline.

2814 signals for which stop and print are cleared by default.
2816 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2818 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
2819 reserved fields to hold a stub unwind entry type. Fix typo.

2824 by linker stub unwind descriptors.
2825 (frameless_function_invocation): Likewise.
2826 (frame_chain_valid): Likewise.
2827 * paread.c (compare_unwind_entries): New function for sorting
2828 unwind table entries.
2829 (read_unwind_info): Rewrite to remove dependency on host endianness.
2830 Read in data from the $UNWIND_END$ subspace which contains linker
2831 stub unwind descriptors. Merge that data into the basic unwind
2834 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2836 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2838 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2839 from either the symbol name or the auxent.
2840 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2843 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2845 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2847 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2849 * README: Update notes for alpha port.
2851 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2853 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2854 for operation fault, constraint fault, and type fault.
2856 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2858 * Makefile.in (init.c): Add comment explaining formatting conventions.
2860 * c-exp.y (parse_number): Assign to temporary between the right
2861 shifts, to work around a bug in the SCO compiler.
2863 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2864 Add various files which were added to GDB recently.
2866 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
2869 * Makefile.in: Add mostlyclean target.
2871 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2875 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2877 * main.c (show_commands): Make return type of extern
2878 history_get be HIST_ENTRY, rather than struct _hist_entry.
2879 (The latter loses with the upcoming merged readline.)
2881 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2883 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2884 const char *, not char *.
2886 * symtab.h (struct symbol): Make section short, not unsigned short.
2888 * symtab.c (lookup_symbol): Add comment about QUIT here.
2890 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2892 * c-exp.y (parse_number): Check for overflow regardless of range
2893 checking. Fix overflow check to use unsigned LONGEST, not
2896 * c-exp.y (parse_number): Make it so that integer constants are
2897 builtin_type_long_long if builtin_type_long isn't big enough or if
2898 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2900 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2901 Print our "()" first, then recurse for the target type.
2903 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2905 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2907 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2909 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2911 * utils.c (request_quit): Re-establish signal handler regardless
2914 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2916 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2918 * i960-tdep.c: Include target.h.
2920 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2922 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2924 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2926 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2927 changes (status -> ourstatus; declare status, etc.).
2928 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2930 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2932 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2934 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2936 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2938 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2940 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2942 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2944 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
2946 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2948 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2949 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2951 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2954 Add search to target vector (#if 0'd until after 4.12):
2955 * target.h (to_search, target_search): Add.
2956 * gdbcore.h, core.c (generic_search): Add.
2957 * remote.c (remote_search): Add.
2958 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2961 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2962 is on, call find_pc_function rather than relying just on the minimal
2963 symbols (probably only matters for symbol readers which don't put
2964 statics in the minimal symbols, but changing this strikes me as
2965 not conservative enough).
2966 Initialize name_location in all cases.
2967 If no symbol and no msymbol, don't print anything symbolic.
2969 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2971 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2973 * printcmd.c (print_address_symbolic): Make it search the
2974 symtabs for variables as well as functions. Add `set print
2975 fast-symbolic-addr' and default it to fast (the old way).
2976 Print line numbers for data items as well as functions.
2978 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2979 address, if a symbol is found (take two more args pointing to
2980 where to store these results).
2982 * symtab.h (find_addr_symbol): Add prototype.
2984 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2986 * objfiles.h: Fix comments to reflect the fact that the phrase
2987 "top of stack" always refers to where the pushing and popping takes
2988 place, regardless of whether it is at the highest or lowest address.
2990 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2992 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2993 compiler generated tag names.
2994 * mdebugread.c (parse_type): Handle cross references to qualified
2996 * valops.c (value_struct_elt): Improve error message if the
2997 address of a method is requested from an object instance.
2998 * valops.c (search_struct_method): Make name_matched non-static
2999 to get it initialized correctly.
3000 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
3001 exclude segment register which are not writable on newer SCO versions.
3003 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3005 * go32-xdep.c: Remove unused function uerror.
3006 (sigsetmask): Declare return type. Declare argument (to match the
3007 way it is called). Explicitly return 0.
3009 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
3011 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
3012 partial_symbol): Shrink the storage sizes of symbols, by making
3013 enums into 1-byte bitfields when compiled __GNUC__, moving all the
3014 enums and small ints to the end of each struct to improve
3015 alignment, and switching the section number from int to unsigned
3018 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
3020 * symtab.c (find_addr_symbol): New routine that will find the nearest
3021 symbol associated with an address. It does so by exhaustive
3022 search of the symtabs, so it's slow but complete.
3024 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
3026 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
3027 to [0,0] rather than [0, end of first source file]. This avoids
3028 problems with other parts of GDB looking for linetables in the
3029 _globals_ symtab. Eliminate variables num_object_files and
3030 first_object_file_end.
3032 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3034 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
3035 (pop_frame): Restore PC2 and LR0 from dummy frames.
3036 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
3037 (setup_arbitrary_frame): Handle 3 args and set up real frames.
3038 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
3039 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
3040 (SETUP_ARBITRARY_FRAME): Define.
3042 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3044 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
3046 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3048 * remote-udi.c (udi_resume): Correct prototype.
3050 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3052 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
3053 hppa_frame_find_saved_regs.
3054 * hppa-tdep.c (dig_fp_from_stack): Delete function.
3055 (prologue_inst_adjust_sp): New function.
3056 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
3057 (skip_prologue): Completely rewrite to use unwind information.
3058 (hppa_frame_find_saved_regs): Likewise.
3060 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3062 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
3063 to convert a signal number with appropriate bounds checking.
3065 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
3067 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3069 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
3070 print a newline to end the display anyway.
3072 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
3073 coprocessor status regs) when popping a frame. This fixes
3074 float exceptions that occur after calling inferior functions.
3076 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
3077 Read and write the fsr (float status register) to/from the child
3078 process along with the float regs. Remove Peter Schauer's change
3079 of May 24 '93, which has higher overhead and doesn't solve the
3080 real problem (which was that FSR wasn't being set).
3082 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
3084 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
3085 stack overflow check isn't right after the register stack
3086 adjustment instruction. Metaware R2.3u compiler moves other
3087 things in front of it. This fix isn't perfect but is what's
3090 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3092 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
3094 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
3095 character filenames.
3096 * configure.in: Change accordingly.
3098 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
3100 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
3101 _filtered io routines from these two files.
3103 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3105 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
3106 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
3107 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
3109 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
3111 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3113 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
3114 printing to gdb_stderr.
3116 * remote-udi.c (udi_kill): Don't close the connection, just set
3117 inferior_pid to zero.
3118 (udi_mourn): Call remove_breakpoints.
3120 * remote-udi.c: Remove obsolete need_artificial_traps comment.
3122 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
3124 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3126 * symtab.c (lookup_symbol): Don't try adding .c to the name.
3128 * remote-bug.c: At the start of each section, reset srec_frame
3131 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
3132 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
3133 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
3134 code which looks for those two waitkinds. Use switch statement.
3135 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
3136 CHILD_SPECIAL_WAITSTATUS.
3138 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
3139 * Move target_signal_from_host, target_signal_to_host, and
3140 store_waitstatus from inftarg.c to target.c. procfs needs them.
3141 * target.c: Include "wait.h" and <signal.h>.
3142 * target.h, infrun.c (proceed), proceed callers: Pass new code
3143 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
3144 enums being treated as unsigned and is cleaner.
3145 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
3147 * infcmd.c (signal_command), infrun.c (signals_info):
3148 Don't allow user to specify numeric equivalent of
3149 TARGET_SIGNAL_DEFAULT.
3151 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
3153 * config/alpha/alpha-netware.mt: New target support for Alpha
3155 * configure.in: Add alpha-*-netware* target.
3157 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
3159 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
3161 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3163 * target.h: Add enum target_waitkind, enum target_signal, and
3164 struct target_waitstatus. Change status argument to target_wait to
3165 be struct target_waitstatus * instead of int *.
3166 * target.h, infrun.c, all targets: Change type of signal arguments
3167 to resume(), proceed(), and target_resume() from int to enum
3169 * All targets (*_wait, *_resume): Change accordingly.
3170 * infcmd.c (program_info, signal_command), throughout infrun.c,
3171 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
3172 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
3173 signal code stuff right with the new signals would be non-trivial).
3174 * inferior.h (stop_signal): Make it enum target_signal not int.
3175 * target.c, target.h (target_signal_to_string, target_signal_to_name,
3176 target_signal_from_name): New functions.
3177 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
3178 store_waitstatus): New functions.
3179 * procfs.c (procfs_notice_signals): Use them.
3180 * i960-tdep.c (i960_fault_to_signal): New function, to replace
3182 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
3184 * objfiles.c (build_objfile_section_table): Don't abort() if
3185 objfile->sections is already set.
3187 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
3188 to match recent change to exec.c.
3192 * main.c (print_gdb_version): Change year to 1994.
3194 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
3195 * Makefile.in (NONSRC): Add ChangeLog-93.
3197 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3199 * stabsread.c (read_type): Allow defining several type numbers
3200 at once (e.g. "(1,2)=(3,4)="...).
3202 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
3204 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
3206 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3208 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
3209 to process_one_symbol.
3210 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
3211 avoid caching a bad endaddr in find_pc_partial_function.
3213 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3215 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
3217 Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3219 * infrun.c (wait_for_inferior): Do not step or step resume past
3220 the end of a one-line function we just stepped into.
