    enter typedefs to opaque aggregates into the symbol tables.
    * mdebugread.c (parse_external):  Remove skip_procedures argument,
    it has always been 1.  Remove code that handled stProc symbols,
    it was never executed and was wrong, as the index of a
    stProc symbol points to the local symbol table and not to the
    auxiliary symbol info. Update caller.
    * mdebugread.c (parse_partial_symbols):  Do not enter external
    stProc symbols into the partial symbol table, they are already
    entered into the minimal symbol table.
    * config/i386/tm-symmetry.h:  Clean up, it is now only used for Dynix.
    Remove all conditionals and definitions for ptx.
    I386_REGNO_TO_SYMMETRY moved to here from symm-tdep.c.
    Fix addresses of floating point registers in REGISTER_U_ADDR.
    STORE_STRUCT_RETURN now handles cc and gcc conventions.
    FRAME_CHAIN, FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC,
    IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET defined to make backtracing through
    signal trampoline code work.

    storing them to obtain valid floating point control registers.
    Store fpu registers.
    * symm-nat.c (print_1167_control_word):  Dynix 3.1.1 defines
    FPA_PCR_CC_C0 and FPA_PCR_CC_C1, avoid duplicate case value.
    * symm-nat.c (fetch_inferior_registers, child_xfer_memory):
    Fix typos.

    * remote.c (getpkt): If we get a timeout, actually retry rather
    than just giving up the first time it happens.
    * remote.c: Document sequence numbers.

    file names.
    * os9kread.c (read_os9k_psymtab): if there's no dbg file, just
    return. Also if file addr is 0 leave it 0, not to relocate.
    * remote-os9k.c (_initialize_remote_os9k): add 'set remotexon',
    'set remotexoff' and 'set remotelog' commands.

Tue Mar 29 12:38:45 1994  Jim Kingdon  ([e-mail])

    * buildsym.c (start_subfile, patch_subfile_names), demangle.c
    (set_demangling_style, set_demangling_command): Use savestring not
    strdup.  We were not dealing properly with a NULL return from

    may not have it).

    * valprint.c (val_print): Remove inaccurate comment about what
    types can be stub types.

    * config/i386/ptx.mh (XDEPFILES): Add coredep.o.  Delete infptrace.o.

    the same size.
    (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.

    * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
    registers as both single and double values (fetching 2nd 32bit half
    as necessary).  Annotate each register printed with its precision.

    * paread.c (read_unwind_info): Fix off-by-one error.

Fri Mar 25 08:33:28 1994  Jim Kingdon  ([e-mail])

    * main.c (complete_command): Deal with it if arg is NULL.

    regarding using the PC--using the PC is necessary and all the
    FIXME comments in the world won't make it go away.

    * valops.c (value_at, value_at_lazy): Give error if we dereference
    a pointer to void.
    * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
    * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.

    if the definition is in another compilation unit from the stab.

    * dbxread.c (end_psymtab): Add comment about empty psymtabs.

Wed Mar 23 07:50:33 1994  Jim Kingdon  ([e-mail])

    * main.c (complete_command): New command, from Rick Sladkey
    <[e-mail]>.
    (symbol_completion_function): Don't declare rl_point and
    rl_line_buffer; they are now declared in readline.h.
    (show_commands): Don't declare history_base; it is declared in
    history.h.
    * command.c (lookup_cmd): Don't delete trailing whitespace.
    Reverts change of 14 May 1989.

Wed Mar 23 16:14:52 1994  Stu Grossman  (grossman at cygnus.com)

    * minsyms.c (prim_record_minimal_symbol):  Move section deduction
    code from prim_record_minimal_symbol_and_info() to here.  Callers
    of the latter can legitimately supply a section number of -1.

Wed Mar 23 07:50:33 1994  Jim Kingdon  ([e-mail])

    * gdbtypes.h, gdbtypes.c: Add comments regarding whether static

    queue if NO_PC_SPACE_QUEUE_RESTORE is defined.

    * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
    for the structure's type.  All callers changed.

    * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
    for each structure argument rather than assuming it's either
    true or false for all structure arguments.

    * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
    on the length structure passed, not the compiler used.

    * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
    argument for the structure's type.

Tue Mar 22 15:28:33 1994  Jim Kingdon  ([e-mail])

    (hppa_push_arguments): Likewise.

Mon Mar 21 11:02:51 1994  Stu Grossman  (grossman at cygnus.com)

    * alpha-tdep.c:  Gobs of changes (many imported from mips-tdep) to
    improve remote debugging efficiency.  Also fixed problems with
    doing function calls for programs with no entry points.
    * infcmd.c (run_stack_dummy):  Use CALL_DUMMY_ADDRESS instead of
    entry_point_address.
    * inferior.h (PC_IN_CALL_DUMMY):  ditto.
    * mdebugread.c (parse_symbol, parse_procedure, parse_external,
    parse_lines):  Pass section_offsets info to these routines so that
    we can relocate symbol table entries upon readin.
    * (psymtab_to_symtab_1):  Set symtab->primary to tell
    objfile_relocate to do relocations for our symbols.
    * (ecoff_relocate_efi):  New routine to relocate adr field of PDRs
    (which hang off of the symbol table).
    * Use prim_record_minimal_symbols_and_info instead of
    prim_record_minimal_symbols to supply section info to make minimal
    symbol relocations work.
    * minsyms.c (prim_record_minimal_symbols_and_info):  If section is
    -1, try to deduce it from ms_type.
    * objfiles.c (objfile_relocate):  Use ALL_OBJFILE_SYMTABS where
    appropriate.  Handle relocation of MIPS_EFI symbols special. Also,
    add code to relocate objfile->sections data structure.
    * remote.c (get_offsets):  Use new protocol message to acquire
    section offsets from the target.
    * (remote_wait):  Get rid of relocation stuff.  That's all handled
    by objfile_relocate now.
    * config/alpha/alpha-nw.mt (TM_FILE):  Use tm-alphanw.h.
    * config/alpha/tm-alpha.h:  Define CALL_DUMMY_ADDRESS, and

    instead of 4.
    * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
    can no longer set this at run time.
    * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
    (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
    * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
    sparc-tdep.c compiles).
    (TARGET_PTR_BIT): Must be a constant now, fix at 64.

Sat Mar 19 08:51:12 1994  Jim Kingdon  ([e-mail])

    * config/m68k/{cisco.mt,tm-cisco.h}: New files.
    * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
    * configure.in: Recognize m68*-cisco*-*.

    * Makefile.in (TAGS): Use variables directly, rather than using
    find, to locate TM_FILE, XM_FILE, and NAT_FILE.  This is faster
    and means that these filenames no longer need be unique across all
    the config/* directories.
    * configure.in: Put the config/*/ into TM_FILE, etc.

    * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
    and trapv exceptions.

    * target.h (struct section_table), objfiles.h (struct obj_section):
    Change name of field sec_ptr to the_bfd_section.  More mnemonic
    and avoids the (sort of, for the ptx compiler) name clash with
    the name of the typedef.
    * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
    solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.

    * utils.c: Include readline.h.
    * Makefile.in (utils.o): Add dependency.

Fri Mar 18 10:25:55 1994  Jim Kingdon  ([e-mail])

    * dstread.c (record_minimal_symbol): New arg objfile.  Pass it to
    prim_record_minimal_symbol.
    Callers: Pass it.

    * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
    computing their offset from the start of the old buffer and adding
    to the new buffer, rather than by assuming we can add the
    difference between the old buffer and the new buffer (it might not
    fit in an int).  Merge in cosmetic differences from emacs regex.c
    version of this macro.

Wed Mar 16 15:28:54 1994  Ian Lance Taylor  ([e-mail])

    * Makefile.in (install-only): Fix use of program_transform_name.

Wed Mar 16 07:18:43 1994  Jim Kingdon  ([e-mail])

    * printcmd.c: Remove "set print fast-symbolic-addr off" command.
    The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
    so I'm nuking the command.
    * symtab.c (find_addr_symbol): Comment out, no longer used.

    * main.c (main): Don't init_source_path for the -cd argument.  Now
    that source_path doesn't contain the current_directory from when
    GDB started up, init_source_path is no longer useful (and is
    harmful because it clobbers a source_path set in $HOME/.gdbinit).

    * TODO: Remove item about line numbers being off.  It is useless
    and confusing without a reproducible test case (it mentions
    proceed(), but I was able to step through proceed without trouble).

Tue Mar 15 13:39:23 1994  Peter Schauer  ([e-mail])

    For Sunos 4.x targets, enable gdb to set breakpoints in shared
    library functions before the executable is run. Retrieve dynamic
    symbols from stripped executables.
    * symtab.h (minimal_symbol_type):  Add mst_solib_trampoline type.
    * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
    symtab.c (list_symbols):  Handle mst_solib_trampoline.
    * minsyms.c (lookup_minimal_symbol):  Handle mst_solib_trampoline
    for all targets, remove IBM6000_TARGET dependencies.
    * dbxread.c (read_dbx_dynamic_symtab):  New function.
    * dbxread.c (dbx_symfile_read):  Use it.
    * dbxread.c (SET_NAMESTRING):  Set namestring to
    "<bad string table index>" instead of "foo" if the string index is
    corrupt.
    * xcoffread.c (read_xcoff_symtab):  Use mst_solib_trampoline instead
    of mst_unknown.
    * symtab.c (list_symbols):  Take from_tty as parameter and pass it
    to break_command. Handle mst_file_* minimal symbol types.
    * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.

Tue Mar 15 11:40:43 1994  Kung Hsu  ([e-mail])

    * environ.c (set_in_environ): Eliminate special handling of PATH and
    GNUTARGET.
    * putenv.c: Removed, conflicts with system declaration of
    putenv on RS/6000 running AIX 3.2.5, and above change makes it
    unnecessary.
    * Makefile.in: Change accordingly.
    * procfs.c (procfs_create_inferior): Change comment accordingly.

Tue Mar 15 10:05:27 1994  Jim Kingdon  ([e-mail])

    (get_i387_state): Use memset not bzero.

    * Version 4.12.3.

    * Makefile.in: Enable commented out getopt_h, bfd_h, etc.  Change
    ieee-float.h to floatformat.h.

    * valprint.c (val_print_string): Ignore error if the error
    happened after a terminating '\0'.

    * c-valprint.c (c_val_print): Never add 1 to return value from
    val_print_string; just return what it returns.

    * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
    looping through all of the enums.
    * infrun.c (signals_info): Use it.

Fri Mar 11 08:08:50 1994  Jim Kingdon  ([e-mail])

    * main.c (main): When printing warning about bad baud rate, don't
    use warning(); it relies on current_target which isn't set up yet.

    * breakpoint.c (_initialize_breakpoint): Update docstring for
    tbreak to match what the code actually does.  Don't mention tbreak
    in docstrings for "enable once" or "enable breakpoints once".

Thu Mar 10 08:52:38 1994  Jim Kingdon  ([e-mail])

    * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
    while (0).  That defeats the whole purpose of using do . . . while (0).
    * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
    list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
    using a ?: expression as an lvalue is not portable.

    * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
    convert a LOC_ARG to a LOC_REF_ARG.  Update code which combines
    'p' and 'r' symbol descriptors into a single symbol to look for a
    LOC_REF_ARG.
    * README, config/sparc/tm-sparc.h: Update comments.

Wed Mar  9 21:43:24 1994  Peter Schauer  ([e-mail])

    * mdebugread.c (parse_type):  Do not complain for types with
    an `indexNil' aux index, these are simply undefined types.
    Remove indexNil check from caller of parse_type.
    * mdebugread.c (parse_partial_symbols):  Do not enter
    stGlobal, scCommon symbols into the minimal symbol table, their
    value is the size of the common, not its address.
    Handle scInit, scFini, scPData and scXData sections.
    Use minimal symbol type mst_file_* for stLabel symbols, instead of
    mst_*.
    Enter stProc symbols into the global_psymbols list once, not into
    the static_psymbols_list.
    Get rid of dummy psymtab if it is empty, to allow proper detection
    of stripped executables.
    * mdebugread.c (cross_ref):  Allow cross references to Fortran
    common blocks.

Wed Mar  9 15:23:19 1994  Jim Kingdon  ([e-mail])

    * stabsread.c (common_block_end, fix_common_block): Stash the
    struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
    as to not assume that a pointer fits in an enum.

    * os9kread.c (fill_sym): check compiler verion number for pre-
    UltraC compiler.
    * os9kread.c (os9k_process_one_symbol): address of symbol is
    relative to section not module.
    * stabsread.c (define_symbol): add symbol type 's' as local
    symbol for os9k.
    * remote-os9k.c: add command 'set monitor_log' to turn on or off
    monitor logging.
    * remote-os9k.c: fix bug in delete breakpoint, single step trace.
    * remote-os9k.c: fix bug in 'set remotebaud' function.
    * remote-os9k.c (rombug_link): minimize checking so to improve
    speed.
    * symfile.c (symbol_file_command): check if failed to link, also make
    the command be able to accept more than one filenames.
    * target.c (target_link): check if failed to link with rombug.
    * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.

Wed Mar  9 15:23:19 1994  Jim Kingdon  ([e-mail])

    * remote-es.c (es1800_child_ops): Don't declare it static.

    end_of_text_address.
    * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.

    * dbxread.c (end_psymtab): Remove old and commented out
    capping_global and capping_static.  Fix comments regarding

    * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
    which performs one (the check_sigtramp2 one) of the functions
    which had been handled by the step_resume_breakpoint.  For each

    step_resume_breakpoint, use the through_sigtramp_breakpoint, or
    operate on both.
    Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
    When setting the frame address of the step resume breakpoint, set
    it to the address for frame *before* the call instruction is
    executed, not after.

    * symfile.h: Don't declare arguments for coff_getfilename.

    * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

    set up the global offset table pointer in pic compiled code.
    * config/mips/tm-mips.h (FIX_CALL_DUMMY):  For big endian targets,
    error() on TYPE_CODE_FLT arguments whose size is greater than 8,
    swap all other TYPE_CODE_FLT arguments as mips_push_arguments

    * printcmd.c (printf_command):  Add missing single-letter
    backslash-escape sequences, and improve error message.

Sun Feb  6 06:55:15 1994  Jim Kingdon  ([e-mail])

    * corelow.c (solib_add_stub, core_open): Pass address of from_tty
    rather than trying to shove an int into a pointer and back out
    again.  This avoids compiler warnings.

    * defs.h (alloca): Declare as void *, not char *, on hpux.
    Don't prototype it, just declare the return type.

Sun Feb  6 03:25:41 1994  Peter Schauer  ([e-mail])

    * config/i386/tm-sun386.h, config/i386/tm-symmetry.h
    (REGISTER_CONVERT_TO_RAW):  Add missing backslash.

Sat Feb  5 08:03:41 1994  Jim Kingdon  ([e-mail])

    * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
    ZERO_REGNUM, just read it as zero without talking to the board.

    * config/i386/tm-i386aix.h (REGISTER_CONVERT_TO_RAW): Add missing
    backslash.
    * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
    to store_floating, not nonexistent variable len.

    * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
    New functions.
    (mips_store_word): Change calling convention to return errors, and
    to provide old contents if the caller wants it.
    (mips_xfer_memory): Deal with errors from mips_store_word.
    * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
    define now that remote-mips.c doesn't use BREAKPOINT.

    * remote-mips.c (mips_create_inferior): Call warning if arguments
    specified, and then execute "set args" command.  Call error, not
    mips_error, if executable file not specified.

    * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
    remote_debug.

    * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
    to unsigned int.

Sat Feb  5 05:27:05 1994  Peter Schauer  ([e-mail])

    * value.h (print_longest):  Rename "value" to "val" in prototype
    declaration because some compilers don't like arguments whose
    names are the same as types.
    * remote.c (remote_xfer_memory):  Cast "myaddr" to unsigned char *
    before passing it to remote_*_bytes.

Fri Feb  4 15:53:18 1994  Steve Chamberlain  ([e-mail])

    * h8500-tdep.c (saved_pc_after_call): The size of the
    pc is memory model dependent. (segmented_command,
    unsegmented_command, _initialize_h8500_tdep): New commands to
    change memory model.
    * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
    command.
    * remote-hms.c (hms_load): Remove breakpoints when loaded.
    (hms_wait): Use new status structure
    (hms_open): Push the target here. (hms_before_main_loop): Not
    here.  (supply_val, hms_fetch_register, hms_store_register):  Cope
    with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
    * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
    all registers in a compact way.

Fri Feb  4 07:41:13 1994  Jim Kingdon  ([e-mail])

    * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
    as CORE_ADDR to match definition in rs6000-tdep.c.

Fri Feb  4 01:14:20 1994  Peter Schauer  ([e-mail])

    * dwarfread.c (process_dies):  Skip nested TAG_compile_unit DIEs.
    * dwarfread.c (add_partial_symbol):  Do not enter opaque aggregate
    definitions into the psymtab.

Thu Feb  3 12:38:58 1994  Jim Kingdon  ([e-mail])

    * m68k-stub.c: Treat mc68332 like mc68020 most places.  Provide
    a special exceptionSize for the 68332.

    * remote-udi.c (udi_attach): If no arguments, print error.

Thu Feb  3 17:34:05 1994  Fred Fish  ([e-mail])

    * Makefile.in (VERSION):  Bump to 4.12.1
    * NEWS, README:  Update to match 4.12 release.

Thu Feb  3 12:38:58 1994  Jim Kingdon  ([e-mail])

    * command.c (empty_sfunc): New function.
    (add_set_cmd): Use it instead of not_just_help_class_command.
    (not_just_help_class_command): Change calling convention back to
    what it was before yesterday's change.

    * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
    of the type if present.

Wed Feb  2 11:16:45 1994  Jim Kingdon  ([e-mail])

    * printcmd.c (decode_format): Don't blithely set the size for
    an address to 'w'.  Make it 'g' or 'h', depending on TARGET_PTR_BIT.

    * defs.h: Just typedef CORE_ADDR to bfd_vma.  Include bfd.h.
    If BFD64, make a LONGEST a BFD_HOST_64_BIT.
    * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
    always just check against INT_MIN and INT_MAX (this also fixes things
    if sizeof (long) > sizeof (int), e.g. Alpha).
    * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
    Don't define LONGEST or BUILTIN_TYPE_LONGEST.
    * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
    BUILTIN_TYPE_UNSIGNED_LONGEST.
    * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
    longest_int and longest_unsigned_int.
    * value.h (struct value): Just align to LONGEST, rather than worrying
    about CC_HAS_LONG_LONG.
    * valarith.c (value_binop): Figure out type ourself based on
    sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST.  The
    point is that we don't depend on CC_HAS_LONG_LONG anymore.
    * valprint.c (val_print_type_code_int): Just call
    extract_unsigned_integer directly, rather than going through
    unpack_long.
    * printcmd.c (decode_format): Remove code which would sometimes
    change 'g' size to 'w' for integers.  print_scalar_formatted handles
    printing huge integers well enough, thank you.

    * command.c (add_set_cmd, not_just_help_class_command): Change
    to make this the sfunc, not cfunc, since that is how we call it.
    * command.h: Comment difference between sfunc and cfunc.
    * demangle.c (set_demangling_command): Add third arg since that
    is how it is called.
    (_initialize_demangler): Use sfunc, not cfunc, for
    set_demangling_command, since that is how it is called.
    Remove show_demangling_command; it has no effect.

    * command.c (shell_escape): Report errors correctly (with error
    message from strerror).

Wed Feb  2 14:35:41 1994  Ian Lance Taylor  ([e-mail])

    * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
    x_scnlen.l rather than x_scnlen to match corresponding change in
    coff/internal.h.

Wed Feb  2 11:16:45 1994  Jim Kingdon  ([e-mail])

    * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
    Change comments regarding TYPE_CODE_BOOL.
    * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
    regardless of the language.
    (value_true): Just call value_logical_not regardless of language.
    * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
    Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
    * language.h: Improve comment for la_builtin_type_vector.
    * m2-lang.c (_initialize_m2_language): Don't add any fields to
    builtin_type_m2_bool.

Tue Feb  1 17:13:32 1994  Kevin Buettner ([e-mail])

    * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
    Define IN_SIGTRAMP and backtrace correctly through signal handlers.

Tue Feb  1 22:13:25 1994  Peter Schauer  ([e-mail])

    * procfs.c (wait_fd):  Handle EINTR error return from PIOCWSTOP ioctl
    by restarting the ioctl.

Tue Feb  1 16:16:25 1994  Jim Kingdon  ([e-mail])

    * target.h (target_wait): Add comment about calling
    return_to_top_level.

Tue Feb  1 12:21:00 1994  Ian Lance Taylor  ([e-mail])

    * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
    additional arguments.
    * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.

Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)

    * sparc-stub.c:  Remove unnecessary #include of memory.h.

Mon Jan 31 12:12:34 1994  Jim Kingdon  ([e-mail])

    * mips-tdep.c: Remove code which sets saved_regs from
    init_extra_frame_info and put it in new function mips_find_saved_regs.
    (READ_FRAME_REG): Remove macro and replace uses with the expansion.
    * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
    check if it is NULL and call mips_find_saved_regs if so.

    * remote-mips.c: Use unfiltered, not filtered, output most places.

    * blockframe.c (get_prev_frame_info): Detect and stop an infinite
    backtrace.  Revise comments.

Mon Jan 31 09:40:33 1994  Peter Schauer  ([e-mail])

    * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
    alpha and irix. The _sigtramp case has to be handled properly
    in the tdep files if we have no ecoff debugging info.
    * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
    mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
    without PC_REGNUM kludge.
    * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
    Clean up handling of mips sigtramp frames, improve comments.

Sat Jan 29 23:25:57 1994  Jeffrey A. Law  ([e-mail])

    * paread.c (read_unwind_info): Fix typo.

    * paread.c (pa_symtab_read): Update the "check_strange_names"
    filter to match GCC's current output.  Filter out section symbols
    (which the HP linker sometimes puts in the wrong place).

Sat Jan 29 07:44:59 1994  Jim Kingdon  ([e-mail])

    * serial.h (SERIAL_SET_TTY_STATE): Comment return value.

    * Makefile.in (TAGS): Just echo one line, rather than the whole thing.

    * Makefile.in: Remove all references to sparcly-nat.c.

    * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
    remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
    duplicating serial.h and target.h.

    * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
    are not used anywhere (a 5 Oct 1993 change removed the uses).

    * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
    * config/m68k/es1800.mt: Add comment.
    * remote-es.c: Extensive changes to update to current conventions.

    * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
    If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
    to achieve the desired timeout.
    * serial.h (serial_t): Add field timeout_remaining.

Fri Jan 28 08:45:02 1994  Jim Kingdon  ([e-mail])

    * c-exp.y (yylex): Reenable nested type code.

Fri Jan 28 15:40:33 1994  Jim Kingdon  ([e-mail])

    * a29k-tdep.c (examine_tag): Add comment regarding argcount.

    * remote-mips.c (mips_ops): Fix docstring.

    * remote-bug.c (bug_ops): Remove spurious newline from docstring.

    * config/m68k/tm-monitor.h: Changes to bring this into accordance
    with the old tm-m68k-em.h:
    (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
    (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
    (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
    Add FIXME regarding GET_LONGJMP_TARGET.

    * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
    * infptrace.c (kill_inferior): Add comments.
    * main.c (quit_command): Call target_close after we kill or
    detach.
    * remote-udi.c (udi_close): Don't error() if QUITTING.

Fri Jan 28 11:55:52 1994  Rob Savoye  ([e-mail])

    * configure.in: Make m68k-coff and aout add monitor support in
    addition to the standard serial support.

Fri Jan 28 08:45:02 1994  Jim Kingdon  ([e-mail])

    * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
    index indexNil.

Fri Jan 28 10:40:34 1994  Jim Kingdon  ([e-mail])

    * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
    * elfread.c (record_minimal_symbol_and_info),
    dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.

Thu Jan 27 15:12:23 1994  Jim Kingdon  ([e-mail])

    * i386-stub.c: Add ".text" right before "mem_fault:".

    * main.c (baud_rate): Add FIXME comment about printing -1 value.

    * remote-utils.c (usage): Fix message to be accurate and conform
    more closely to normal conventions.

    * remote-utils.c (gr_files_info): Have the exec_bfd test control
    whether to show information about exec_bfd, and not control whether
    to show information about device and speed.

    * remote-utils.c (gr_open): If sr_get_device returns NULL, give
    usage message, don't dump core.

    * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
    for variable size array.
    (bug_fetch_register, bug_store_register): Rename "value" to
    "fpreg_buf" because some compilers don't like variables whose
    names are the same as types.
    (bug_store_register): Use a cast when converting char * to
    unsigned char *.

    * symmisc.c (maintenance_print_symbols): Don't refer to the name
    of the command in error message (the text was referring to the old
    name of the command).

    * symmisc.c (dump_symtab): Fix args to fprintf_filtered.

    * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
    full details on structure elements without names.  This partially
    reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
    of those changes was accidental.

    * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
    defined, make it an error to specify a single argument which is not
    a frame number.

    * Makefile.in (version.c), main.c (print_gdb_version): Use
    host_alias and target_alias, not host_canonical and
    target_canonical, to print configuration.

Wed Jan 26 10:57:21 1994  Jim Kingdon  ([e-mail])

    * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
    of builtin_type_long.  It is necessary to get a type which is
    TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.

    Fix many sins which will come up in 32 bit x 64 bit GDB, and
    various miscellaneous things discovered in the process:
    * printcmd.c, defs.h (print_address_numeric): New function.
    * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
    breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
    cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
    printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
    Use it.
    * utils.c, defs.h (gdb_print_address): New function.
    * expprint (dump_expression), gdbtypes.h: Use it.
    * breakpoint.c (describe_other_breakpoints),
    symmisc.c (dump_symtab, print_symbol):
    Use filtered not unfiltered I/O.
    (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
    just run gdb under a debugger for this (and it had problems with
    printing addresses, how to print b->shadow, etc.).
    * buildsym.c (make_blockvector), core.c (memory_error),
    exec.c (print_section_info), maint.c (print_section_table),
    mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
    symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
    Add comments saying code is broken.  Marked with "FIXME-32x64".
    * dbxread.c (process_one_symbol), partial-stab.h (default),
    remote-vx.c (vx_run_files_info):
    Don't cast int being passed to local_hex_string.
    * symmisc.c (print_symbol): Don't cast long being passed to %lx.
    * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
    only being a long.
    * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
    and LOC_LOCAL.
    * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
    * source.c: Include <sys/types.h> regardless of USG.

Tue Jan 25 12:58:26 1994  Peter Schauer  ([e-mail])

    * valops.c (value_assign):  Set `type' after coercing toval.
    * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
    Use extract_unsigned_integer to get the address of a reference.

Tue Jan 25 11:31:53 1994  Jim Kingdon  ([e-mail])

    * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
    AIX can use ? instead of \ for continuation.  Deal with it.

    * paread.c (read_unwind_info): Just assign to objfile->obj_private,
    not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
    the HP compiler in ANSI mode doesn't like.

    * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
    based on USG, rather than defining HAVE_SIGSETMASK to an
    expression containing defined.  Having a macro used in #if expand
    to an expression containing "defined" is undefined according to
    ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
    it to.

Mon Jan 24 20:51:29 1994  John Gilmore  ([e-mail])

    * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
    Clean up the changes of 11 Jan, as recommended by Peter Schauer.

Fri Jan 21 19:10:44 1994  Per Bothner  ([e-mail])

    * ch-exp.y (match_string_literal):  Allow a zero-length string.
    * ch-lang.c (chill_printstr):  Don't print zero-length string funny.

Sat Jan 22 17:08:48 1994  Jim Kingdon  ([e-mail])

    * i386aix-nat.c (i386_float_info): Reverse order of registers before
    passing them to print_387_status.
    (print_387_status): Don't subtract top from 7 before using it.
    * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
    from 7; the above explains it.

Sat Jan 22 20:25:11 1994  Peter Schauer  ([e-mail])

    * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
    pointer value when fixing up the frame at the start of a function.

Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)

    * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
    Sparc from the stack.

Sat Jan 22 08:30:42 1994  Jim Kingdon  ([e-mail])

    * remote-mips.c (mips_initialize): Clear mips_initializing via
    cleanup chain, not directly.

    * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
    of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
    munging the timeout due to the limited range of c_cc[VTIME].

    * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
    * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
    m3-nat.c (m3_create_inferior): Pass it.
    * procfs.c: Remove ptrace function.  It was declared in a way which
    conflicted with the prototype in unistd.h on Solaris.

Sat Jan 22 01:37:40 1994  Peter Schauer  ([e-mail])

    * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
    in the sigcontext if it is a signal trampoline frame.
    * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
    Define for Solaris2.

Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)

    * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
    config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
    tm-sparc.h so they can be overridden if necessary.

Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)

    * lynx-nat.c:  Add Sparc support.
    * sparcly-nat.c:  Remove.  It's useless.
    * config/sparc/nm-sparclynx.h:  Rewrite.
    * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
    with lynx-nat.o
    * config/sparc/tm-sparclynx.h:  Rewrite.

Fri Jan 21 19:08:48 1994  Ian Lance Taylor  ([e-mail])

    * rs6000-pinsn.c: Use the new disassembler in the opcodes
    directory.  Old code was discarded, since the new opcode table has
    a different format.

Fri Jan 21 14:28:30 1994  Fred Fish  ([e-mail])

    * Makefile.in (realclean):  Remove info files per make-stds.texi.

Fri Jan 21 12:47:53 1994  Jim Kingdon  ([e-mail])

    * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
    if N_SO_ADDRESS_MAYBE_MISSING is defined.
    * config/sparc/tm-sun4sol2.h: Define it.

Thu Jan 20 15:04:24 1994  Peter Schauer  ([e-mail])

    * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
    if we did not find a symbol.

Fri Jan 21 08:20:18 1994  Jeffrey A. Law  ([e-mail])

    * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
    is not defined.

    * hppab-nat.c (call_ptrace): Delete redundant function.
    (kill_inferior, attach, detach, child_resume): Likewise.
    (child_xfer_memory): Likewise.

    * hppah-nat.c (call_ptrace): Delete redundant function.
    (kill_inferior, attach, detach, child_resume): Likewise.

    * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.

    * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.

    * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.

    * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
    (CHILD_XFER_MEMORY): Define.
    (PT_*): Define so that generic infptrace.c code can be used.

Fri Jan 21 09:23:33 1994  Jim Kingdon  ([e-mail])

    * xcoffread.c (xcoff_symfile_read): Make second parameter a
    struct section_offsets *, not a (nonexistent) struct section_offset *.

    * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
    internal_xcoff_symtab, not an array of one of them.  Change lots of
    "main_aux" to "&main_aux" and so on.

    * coffread.c, xcoffread.c: Include <coff/internal.h>
    before "symfile.h".

Thu Jan 20 17:30:55 1994  Jim Kingdon  ([e-mail])

    * coffread.c (coff_getfilename): Make it not static.

    * xcoffread.c (read_xcoff_symtab): complain() not abort().

    * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
    a completely gratuitous difference between xcoffread.c and coffread.c).

Wed Jan 19 15:09:44 1994  Jim Kingdon  ([e-mail])

    * infrun.c (wait_for_inferior): Don't set frame for
    step_resume_breakpoint for IN_SIGTRAMP cases.

    * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
    breakpoint.c (bpstat_what): Move step_resume from its own field of
    the struct bpstat_what into the main_action.  Make it override
    other breakpoints.  This is a conservative change in the sense
    that before the step resume breakpoint was a breakpoint.c
    breakpoint, hitting the step resume breakpoint overrode even
    calling bpstat_stop_status.

Wed Jan 19 12:40:25 1994  Peter Schauer  ([e-mail])

    * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
    in case execution was stopped in the called function.
    * stack.c (print_frame_info, frame_info):  If backtracing through
    a call dummy, handle the starting source line number on a line
    boundary like backtracing through sigtramp.
    * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
    for call dummy frame right.  Remove old test for dummy frame,
    it has been unused at least since gdb-3.5.
    * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
    of the dummy frame.

Tue Jan 18 16:16:35 1994  Jim Kingdon  ([e-mail])

    * infrun.c (signals_info), target.c (target_signal_from_name):
    Use ugly casts to avoid enumvar < enumvar or enumvar++.

Mon Jan 17 22:00:15 1994  Jim Kingdon  ([e-mail])

    * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
    * inflow.c (terminal_ours_1): When discussing how to deal with the
    tty state, make note of query() as well as readline.

    * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
    signals for which stop and print are cleared by default.

Mon Jan 17 20:00:51 1994  Jeffrey A. Law  ([e-mail])

    * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
    reserved fields to hold a stub unwind entry type.  Fix typo.
    (stub_unwind_entry): New structure for raw stub unwind entries.
    (stub_unwind_types): The types of stubs we may encounter.

    * hppa-tdep.c (rp_saved): Use additional information provided
    by linker stub unwind descriptors.
    (frameless_function_invocation): Likewise.
    (frame_chain_valid): Likewise.
    * paread.c (compare_unwind_entries): New function for sorting
    unwind table entries.
    (read_unwind_info): Rewrite to remove dependency on host endianness.
    Read in data from the $UNWIND_END$ subspace which contains linker
    stub unwind descriptors.  Merge that data into the basic unwind
    table.

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

Mon Jan 17 22:00:15 1994  Jim Kingdon  ([e-mail])

    * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
    from either the symbol name or the auxent.
    * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
    no longer static.

Mon Jan 17 13:35:01 1994  Fred Fish  ([e-mail])

    * Makefile.in (ALLPARAM):  Change irix5.h to nm-irix5.h.

Mon Jan 17 12:35:42 1994  Peter Schauer  ([e-mail])

    * README:  Update notes for alpha port.

Mon Jan 17 11:15:57 1994  Jim Kingdon  ([e-mail])

    * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL

    * c-exp.y (parse_number): Assign to temporary between the right
    shifts, to work around a bug in the SCO compiler.

    * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
    Add various files which were added to GDB recently.

    * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
    within_function.

    * Makefile.in: Add mostlyclean target.

Sat Jan 15 10:20:13 1994  Jim Kingdon  ([e-mail])

    * Version 4.11.4.

Sat Jan 15 18:27:34 1994  Per Bothner  ([e-mail])

    * main.c (show_commands):  Make return type of extern
    history_get be HIST_ENTRY, rather than struct _hist_entry.
    (The latter loses with the upcoming merged readline.)

Sat Jan 15 10:20:13 1994  Jim Kingdon  ([e-mail])

    * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
    const char *, not char *.

    * symtab.h (struct symbol): Make section short, not unsigned short.

    * symtab.c (lookup_symbol): Add comment about QUIT here.

    * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.

    * c-exp.y (parse_number): Check for overflow regardless of range
    checking.  Fix overflow check to use unsigned LONGEST, not
    unsigned int.

    * c-exp.y (parse_number): Make it so that integer constants are
    builtin_type_long_long if builtin_type_long isn't big enough or if
    an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.

    * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
    Print our "()" first, then recurse for the target type.

Fri Jan 14 21:55:39 1994  Jim Kingdon  ([e-mail])

    * remote-udi.c (udi_create_inferior): Quote empty execfile argument.

    * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".

Fri Jan 14 14:17:06 1994  Jim Kingdon  ([e-mail])

    * utils.c (request_quit): Re-establish signal handler regardless
    of USG.

    * config/mips/xm-irix4.h: Define HAVE_TERMIOS.

Fri Jan 14 21:55:39 1994  Jim Kingdon  ([e-mail])

    * i960-tdep.c: Include target.h.

Fri Jan 14 17:12:28 1994  Stan Shebs  ([e-mail])

    * lynx-nat.c (sys/wait.h): Don't use absolute pathname.

Fri Jan 14 11:06:10 1994  Jim Kingdon  ([e-mail])

    * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
    changes (status -> ourstatus; declare status, etc.).
    * config/nm-lynx.h: Fix child_wait prototype and include target.h.

Fri Jan 14 14:17:06 1994  Jim Kingdon  ([e-mail])

    * Makefile.in (ALLPARAM): Add config/nm-lynx.h.

Fri Jan 14 11:49:44 1994  Ian Lance Taylor  ([e-mail])

    * remote-mips.c (mips_request, mips_wait): Correct prototypes.

Fri Jan 14 11:37:17 1994  Jim Kingdon  ([e-mail])

    * config/i386/xm-linux.h: Define HAVE_TERMIOS.

Fri Jan 14 01:04:36 1994  Peter Schauer  ([e-mail])

    * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.

Thu Jan 13 10:32:38 1994  Jim Kingdon  ([e-mail])

    * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
    is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.

    * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
    writing it.

    Add search to target vector (#if 0'd until after 4.12):
    * target.h (to_search, target_search): Add.
    * gdbcore.h, core.c (generic_search): Add.
    * remote.c (remote_search): Add.
    * a29k-tdep.c (init_frame_info): Use target_search to find traceback
    tag.

    * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
    is on, call find_pc_function rather than relying just on the minimal
    symbols (probably only matters for symbol readers which don't put
    statics in the minimal symbols, but changing this strikes me as
    not conservative enough).
    Initialize name_location in all cases.
    If no symbol and no msymbol, don't print anything symbolic.

    * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.

Wed Jan 12 20:53:16 1994  John Gilmore  ([e-mail])

    * printcmd.c (print_address_symbolic):  Make it search the
    symtabs for variables as well as functions.  Add `set print
    fast-symbolic-addr' and default it to fast (the old way).
    Print line numbers for data items as well as functions.

    * symtab.c (find_addr_symbol):  Return the symtab and the symbol
    address, if a symbol is found (take two more args pointing to
    where to store these results).

    * symtab.h (find_addr_symbol):  Add prototype.

Wed Jan 12 19:32:11 1994  Jim Kingdon  ([e-mail])

    * objfiles.h: Fix comments to reflect the fact that the phrase
    "top of stack" always refers to where the pushing and popping takes
    place, regardless of whether it is at the highest or lowest address.

Wed Jan 12 13:23:37 1994  Peter Schauer  ([e-mail])

    * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
    compiler generated tag names.
    * mdebugread.c (parse_type):  Handle cross references to qualified
    aggregate types.
    * valops.c (value_struct_elt):  Improve error message if the
    address of a method is requested from an object instance.
    * valops.c (search_struct_method):  Make name_matched non-static
    to get it initialized correctly.
    * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
    exclude segment register which are not writable on newer SCO versions.

Wed Jan 12 14:44:45 1994  Jim Kingdon  ([e-mail])

    * go32-xdep.c: Remove unused function uerror.
    (sigsetmask): Declare return type.  Declare argument (to match the
    way it is called).  Explicitly return 0.

Wed Jan 12 01:44:25 1994  John Gilmore  ([e-mail])

    * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
    partial_symbol):  Shrink the storage sizes of symbols, by making
    enums into 1-byte bitfields when compiled __GNUC__, moving all the
    enums and small ints to the end of each struct to improve
    alignment, and switching the section number from int to unsigned
    short.

Wed Jan 12 00:16:26 1994  John Gilmore  ([e-mail])

    * symtab.c (find_addr_symbol):  New routine that will find the nearest
    symbol associated with an address.  It does so by exhaustive
    search of the symtabs, so it's slow but complete.

Tue Jan 11 23:57:30 1994  John Gilmore  ([e-mail])

    * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
    to [0,0] rather than [0, end of first source file].  This avoids
    problems with other parts of GDB looking for linetables in the
    _globals_ symtab.  Eliminate variables num_object_files and
    first_object_file_end.

Tue Jan 11 00:53:46 1994  John Gilmore  ([e-mail])

    * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
    (pop_frame):  Restore PC2 and LR0 from dummy frames.
    (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
    (setup_arbitrary_frame):  Handle 3 args and set up real frames.
    * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
    (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
    (SETUP_ARBITRARY_FRAME):  Define.

Tue Jan 11 06:59:10 1994  Jim Kingdon  ([e-mail])

    * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.

Tue Jan 11 14:27:03 1994  Ian Lance Taylor  ([e-mail])

    * remote-udi.c (udi_resume): Correct prototype.

Tue Jan 11 11:10:30 1994  Jeffrey A. Law  ([e-mail])

        * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
    hppa_frame_find_saved_regs.
    * hppa-tdep.c (dig_fp_from_stack): Delete function.
    (prologue_inst_adjust_sp): New function.
    (is_branch, inst_saves_gr, inst_saves_fr): New functions.
    (skip_prologue): Completely rewrite to use unwind information.
    (hppa_frame_find_saved_regs): Likewise.

Tue Jan 11 06:59:10 1994  Jim Kingdon  ([e-mail])

    * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
    to convert a signal number with appropriate bounds checking.

    * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).

Tue Jan 11 00:53:46 1994  John Gilmore  ([e-mail])

    * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
    print a newline to end the display anyway.

    * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
    coprocessor status regs) when popping a frame.  This fixes
    float exceptions that occur after calling inferior functions.

    * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
    Read and write the fsr (float status register) to/from the child
    process along with the float regs.  Remove Peter Schauer's change
    of May 24 '93, which has higher overhead and doesn't solve the
    real problem (which was that FSR wasn't being set).

Mon Jan 10 23:16:42 1994  John Gilmore  ([e-mail])

    * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
    stack overflow check isn't right after the register stack
    adjustment instruction.  Metaware R2.3u compiler moves other
    things in front of it.  This fix isn't perfect but is what's
    running.

Mon Jan 10 20:08:23 1994  Jim Kingdon  ([e-mail])

    * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.

    * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
    character filenames.
    * configure.in: Change accordingly.

Mon Jan 10 15:48:36 1994  Tom Lord  ([e-mail])

    * m68k-stub.c, sparc-stub.c: removed spurious introduction of
    _filtered io routines from these two files.

Fri Jan  7 12:42:45 1994  Peter Schauer  ([e-mail])

    * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
    config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
    * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
    DEC c89.
    * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.

Fri Jan  7 12:55:25 1994  Jim Kingdon  ([e-mail])

    * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
    printing to gdb_stderr.

    * remote-udi.c (udi_kill): Don't close the connection, just set
    inferior_pid to zero.
    (udi_mourn): Call remove_breakpoints.

    * remote-udi.c: Remove obsolete need_artificial_traps comment.

    * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.

Thu Jan  6 07:17:53 1994  Jim Kingdon  ([e-mail])

    * symtab.c (lookup_symbol): Don't try adding .c to the name.

    * remote-bug.c: At the start of each section, reset srec_frame
    back to 160.

    * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
    * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
    * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
    code which looks for those two waitkinds.  Use switch statement.
    * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
    CHILD_SPECIAL_WAITSTATUS.

    * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
    * Move target_signal_from_host, target_signal_to_host, and
    store_waitstatus from inftarg.c to target.c.  procfs needs them.
    * target.c: Include "wait.h" and <signal.h>.
    * target.h, infrun.c (proceed), proceed callers: Pass new code
    TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
    enums being treated as unsigned and is cleaner.
    * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
    TARGET_SIGNAL_0.
    * infcmd.c (signal_command), infrun.c (signals_info):
    Don't allow user to specify numeric equivalent of
    TARGET_SIGNAL_DEFAULT.

Tue Jan  4 15:34:36 1994  Stu Grossman  ([e-mail])

    * config/alpha/alpha-netware.mt:  New target support for Alpha
    running Netware.
    * configure.in:  Add alpha-*-netware* target.

Tue Jan  4 14:51:35 1994  Stan Shebs  ([e-mail])

    * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.

Tue Jan  4 09:47:14 1994  Jim Kingdon  ([e-mail])

    * target.h: Add enum target_waitkind, enum target_signal, and
    struct target_waitstatus.  Change status argument to target_wait to
    be struct target_waitstatus * instead of int *.
    * target.h, infrun.c, all targets: Change type of signal arguments
    to resume(), proceed(), and target_resume() from int to enum
    target_signal.
    * All targets (*_wait, *_resume): Change accordingly.
    * infcmd.c (program_info, signal_command), throughout infrun.c,
    * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
    * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
    signal code stuff right with the new signals would be non-trivial).
    * inferior.h (stop_signal): Make it enum target_signal not int.
    * target.c, target.h (target_signal_to_string, target_signal_to_name,
    target_signal_from_name): New functions.
    * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
    store_waitstatus): New functions.
    * procfs.c (procfs_notice_signals): Use them.
    * i960-tdep.c (i960_fault_to_signal): New function, to replace
    print_fault.
    * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.

    * objfiles.c (build_objfile_section_table): Don't abort() if
    objfile->sections is already set.

    * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
    to match recent change to exec.c.

    * Version 4.11.3.

    * main.c (print_gdb_version): Change year to 1994.

    * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
    * Makefile.in (NONSRC): Add ChangeLog-93.

Mon Jan  3 11:57:29 1994  Jim Kingdon  ([e-mail])

    * stabsread.c (read_type): Allow defining several type numbers
    at once (e.g. "(1,2)=(3,4)="...).

    * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).

    * breakpoint.c (frame_in_dummy): Check PC as well as frame.

Mon Jan  3 02:47:03 1994  Peter Schauer  ([e-mail])

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

Sun Jan  2 21:41:17 1994  Jim Kingdon  ([e-mail])

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