Mon Mar 21 11:50:28 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * hppa-tdep.c (hppa_fix_call_dummy): Use value_ptr.
        (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
        VM_MIN_ADDRESS.
        * config/alpha/tm-alphanw.h:  DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.

Sun Mar 20 15:21:57 1994  Doug Evans  (dje@cygnus.com)

        * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
        instead of 4.

start-sanitize-v9
        * 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.
end-sanitize-v9

Sat Mar 19 08:51:12 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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.

        * remote.c (getpkt): Add support for run-length encoding.

Fri Mar 18 19:11:15 1994  Steve Chamberlain  (sac@jonny.cygnus.com)

        * utils.c (prompt_for_continue): Call readline, not gdb_readline.

Fri Mar 18 10:25:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (ian@tweedledumb.cygnus.com)

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

Wed Mar 16 07:18:43 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        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  (kung@mexican.cygnus.com)

        * c-exp.y(yylex): fix potential memory overflow.

Tue Mar 15 10:33:28 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@cygnus.com)

        * rs6000-tdep.c: Change value to value_ptr.

Sun Mar 13 09:45:51 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * i386m3-nat.c: Include floatformat.h.
        (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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * 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.

Wed Mar  9 18:56:36 1994  Kung Hsu  (kung@mexican.cygnus.com)

        * os9kread.c (fill_sym): check compiler verion number for pre-

        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.

        (record_minimal_symbol, read_dbx_symtab): Set it.
        (read_dbx_symtab): Use lowest_text_address + text_size instead of
        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
        N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.

        * parser-defs.h: Add "extern" to start of variable declarations so
        we don't end up with commons.
        * parse.c: Define these variables.

        * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it

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

        (frame_saved_pc): Handle signal trampolines and interrupt routines.
        (frame_chain, frame_chain_valid): Likewise.
        (hppa_frame_find_saved_regs): Likewise.  Also deal with special

        valarith.c, valops.c, valprint.c, value.h, values.c: Replace
        value with value_ptr.  This is for the ptx compiler.
        * objfiles.h, target.h: Don't declare a "sec_ptr" field using a

        * symm-tdep.c: Remove lots of stuff which duplicates stuff from
        i386-tdep.c.  Remove register_addr and ptx_coff_regno_to_gdb.
        * i386-tdep.c (i386_frame_find_saved_regs): Put in
        I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix
        someday.
        * config/i386/nm-symmetry.h: Change KERNEL_U_ADDR.  Move
        stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
        symm-nat.c.  Define CHILD_WAIT and declare child_wait().
        * config/i386/tm-symmetry.h: Remove call function stuff; stuff in
        tm-i386v.h is apparently OK.
        * config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
        HAVE_TERMIO.  Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and

        * symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
        (CORE_ADDR)0, from target_link, since that is what it uses.
        Process name at end, not during parsing (like we did before Kung's
        change), so that -readnow and -mapped can appear anywhere.
        Make text_relocation a local variable.
        * config/i386/i386os9k.mt: Fix comment.

        enumeration constant.
        (os9k_init_type_vector): New function.

        a symbol file is requested to load.
        * main.c (quit_command): take out 'inferior_pid != 0' condition,
        because in cross mode there's no inferior pid, bit they need to
        be detached.
        Makefile.in: add os9kread.c os9kstab.c and .o's.
        configure.in: add i386os9k target.

        the delay slot.

        * valprint.c (val_print_string): If errcode is set, always print
        an error, regardless of force_ellipsis.  In the non-EIO case,
        just print the error message rather than calling error().  Don't
        access *(bufptr-1) if bufptr points to the start of the buffer.
        When looking for '\0', don't increment bufptr and addr if bufptr
        started out already at limit.  If an error happens on fetching the
        first character, don't print the string.

        target.h, remote-es.c, remote-nindy.c: Don't set baud rate if
        baud_rate is -1.  Remove sr_get_baud_rate and sr_set_baud_rate;

        don't print a baud rate if baud_rate is -1.

        * coffread.c (read_coff_symtab): Pass mst_file_* to
        record_minimal_symbol for C_STAT symbols.  Put C_EXT and C_STAT
        symbols in the minimal symbols regardless of SDB_TYPE.

        if we hit a bp_through_sigtramp breakpoint.  Remove kludge which
        ignored bs->stop for a bp_step_resume breakpoint.
        * 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
        use of the step_resume_breakpoint, make it still use the
        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.

        * mips-tdep.c (mips_print_register): Print integers using
        print_scalar_formatted rather than duplicating all the
        CC_HAS_LONG_LONG and so on.
        (mips_push_dummy_frame): Use read_register_gen rather than using
        read_register and then putting it back in target format with
        store_unsigned_integer.  If registers are more than 4 bytes, give
        an error rather than have some registers overwrite other
        registers.
        #if 0 unused include of opcode/mips.h.

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

        error() on TYPE_CODE_FLT arguments whose size is greater than 8,
        swap all other TYPE_CODE_FLT arguments as mips_push_arguments
        ensures that floats are promoted to doubles before they are pushed
        on the stack.

        * sparclite/Makefile.in, sparclite/salib.c, sparclite/sparclite.h:
        Fixup cache_on and flush_i_cache so that they work for both the
        930 and 932 processors.  Rewrite most low level funcs (uart
        access & cache stuff) to use new ASI access macros in sparclite.h.
        Also make it easy to access second serial port.

        it via udi_close.
        (udi_create_inferior): If udi_session_id is negative, open a new

Fri Feb  4 07:41:13 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (fnf@cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (ian@tweedledumb.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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 (kev@cujo.geg.mot.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

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

Tue Feb  1 16:16:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

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

Tue Feb  1 12:21:00 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (law@snake.cs.utah.edu)

        * 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  (kingdon@deneb.cygnus.com)

        * 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  (kingdon@deneb.cygnus.com)

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

Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (rob@darkstar.cygnus.com)

        * 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  (kingdon@deneb.cygnus.com)

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

Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (bothner@kalessin.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@deneb.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (ian@tweedledumb.cygnus.com)

        * 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  (fnf@cygnus.com)

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

Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (law@snake.cs.utah.edu)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * infcmd.c (signal_command): Accept 0 as legitimate signal number.

        (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
        * 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.

        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  (fnf@cygnus.com)

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

Mon Jan 17 12:35:42 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

        * README:  Update notes for alpha port.

Mon Jan 17 11:15:57 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
        for operation fault, constraint fault, and type fault.

Sun Jan 16 12:46:01 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * Makefile.in (init.c): Add comment explaining formatting conventions.

        * 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.

Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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.

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

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

Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)

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

Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

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

Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

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

Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

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

Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

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

Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (kingdon@deneb.cygnus.com)

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

Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

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

Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * 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  (kingdon@deneb.cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (gnu@cygnus.com)

        * 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  (kingdon@deneb.cygnus.com)

        * 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  (lord@rtl.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@deneb.cygnus.com)

        * 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  (grossman@cygnus.com)

        * 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  (shebs@andros.cygnus.com)

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

Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (pes@regent.e-technik.tu-muenchen.de)

        * 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  (kingdon@lioth.cygnus.com)

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

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