        section in so_list struct.
        * solib.c (symbol_add_stub):  Pass base address of ".text"
        section to symbol_file_add, rather than the load address of
        the shared library.  On SunOS they are the same.  On SVR4 they
        are not.

Tue Mar 31 17:48:15 1992  Stu Grossman  (grossman at cygnus.com)

        * mipsread.c (parse_procedure):  PDR.isym should get pointer to

        * Makefile.in (VERSION):  4.4.8

        * procfs.c (open_proc_file):  Disable inherit-on-fork flag so that
        commands in .cshrc/.profile won't get traced.

Tue Mar 31 08:11:58 1992  John Gilmore  (gnu at cygnus.com)

        * elfread.c (elf_symtab_read):  Use xmalloc, not bfd_xmalloc.

        * sparc-tdep.c (single_step):  Lint.
        * utils.c (mrealloc):  Handle realloc (0, size) case here.

Mon Mar 30 16:50:43 1992  Stu Grossman  (grossman at cygnus.com)

        opposed to m[ht]-*!

        * config/irix4.mh:  Don't use coredep.o.  It doesn't work with procfs.

        * mipsread.c (parse_symbol, parse_procedure):  Re-do the way that
        .gdbinfo. symbols are created.  Move creation from parse_procedure
        to parse_symbol, where it is fairly easy to grow the symtab.  This
        also fixes a symtab trashing bug on all mips-based systems.
        * (got_numargs, lookup_numargs, free_numargs):  Delete.  Not
        needed anymore.
        * tm-mips.h, tm-iris3.h, mips-tdep.c, mipsread.c:  Re-do struct
        mips_extra_func_info, and all the PROC_xxx macros that look at it.

        (cplus_mangled_symbol):  Move inline into lookup_symbol.
        * xcoffexec.c (relocate_objfile_msymbols):  Remove poor hack.

        unused copy!

        * buildsym.c (define_symbol):  Handle global register variables
        (from Pierre Willard).  Complain if register numbers are too large.

        * symfile.c (symbol_file_add):  Use OBJF_SYMS to decide  whether
        or not to try reading symbols from a mapped objfile.  Plugs memory
        leak due to shared libraries generating no psymtabs or symtabs.

Fri Mar 27 15:44:55 1992  John Gilmore  (gnu at cygnus.com)

        (Reported by Peggy Fieland.)

Thu Mar 26 17:01:18 1992  Fred Fish  (fnf@cygnus.com)

        * coffread.c (coff_symfile_init):  Update comment.
        * dbxread.c (DBX_SYMFILE_INFO, DBX_TEXT_SECT, DBX_SYMCOUNT,
        DBX_STRINGTAB, DBX_STRINGTAB_SIZE, DBX_SYMTAB_OFFSET):  Define
        macros to access the dbx specific objfile information.

        read_dbx_symtab):  Remove the stringtab and stringtab_size params
        from the function prototypes, the function definition, and the
        function calls.  These are now available via DBX_STRINGTAB and
        DBX_STRINGTAB_SIZE using the objfile pointer.
        * dbxread.c (dbx_symfile_read):  Relocate addr before using as
        an arg to read_dbx_symtab.
        * dbxread.c (dbx_symfile_read):  Remove code that free'd the
        stringtab and the dbx specific per-objfile private info.
        * dbxread.c (init_psymbol_list):  Remove symbol count from passed
        args in prototype, function definition, and function calls.  It is
        now available via the DBX_SYMCOUNT macro using the objfile
        pointer.
        * dbxread.c (dbx_symfile_read, dbx_symfile_init):  Remove the
        local instance of struct dbx_symfile_info and replace with DBX_*
        macros.
        * dbxread.c (dbx_symfile_read):  Remove init's of now deleted
        symfile_string_table and symfile_string_table_size.
        * dbxread.c (dbx_symfile_finish):  Remove now obsolete free of
        symfile_string_table.
        * dbxread.c (init_psymbol_list):  Use DBX_SYMCOUNT.

        stringtab size variables.  Remove all code that used to reread
        the stringtab.
        * objfiles.c (allocate_objfile):  Move calls to init_malloc()
        to prior to any calls to mmalloc for the objfile specific heap.
        * utils.c (init_malloc):  Document the requirement that for each
        heap for which corruption checking is desired, that init_mmalloc
        must be called prior to any mmalloc calls on the heap.

Thu Mar 26 13:20:06 1992  Per Bothner  (bothner@cygnus.com)

        * rs6000-pinsn.c:  Make dis-assembly output more like
        other targets:  Don't print instruction in hex before
        the assembly;  use print_address to print out jump
        destinations.

Wed Mar 25 16:52:35 1992  Per Bothner  (bothner@cygnus.com)

        * c-exp.y, gdbtypes.h:  Add builtin_type_signed_char.
        * cplus-dem.c:  Support "Sc" meaning "signed char".

Wed Mar 25 15:21:44 1992  Stu Grossman  (grossman at cygnus.com)

        * configure.in:  fix iris/iris3.

Wed Mar 25 14:55:48 1992  Per Bothner  (bothner@cygnus.com)

        * command.c, main.c (various places):  Use ctype.h macros
        (such as isupper(x)),  instead of hard-wiring in ASCII-isms
        (such as (x >= 'A' && x <= 'Z')).
        (There are still more of these in other files.)
        * main.c (defined_command):  Lower-case the user's
        new command before entering it.  Needed because
        command lookup is case-insensitive (and also lower-cases).
        (Based on Metin's earlier patch.)

Thu Mar 19 18:49:45 1992  Per Bothner  (bothner@cygnus.com)

        More C++ improvements (pointers to members, qualified names).
        * c-exp.y:  Support exp.type::name and exp->type::name
        syntaxes.  (Unfortunately, doesn't work for static members.)
        * c-exp.y, eval.c:   Make type::~type work better.
        * eval.c (evaluate_subexp: OP_SCOPE):  Replace use of
        value_static_field by value_struct_elt_for_reference.
        * eval.c (evaluate_subexp):  Merge code for STRUCTOP_MEMBER
        and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
        * eval.c (evaluate_subexp):  Remove special case for UNOP_ADDR
        for OP_SCOPE operand; no point in it now that we use lazy
        reading of values, and use "reference to member" objects.
        * gdbtypes.h:  Clarify comment.
        * valops.c:  Change value_struct_elt_for_address to return
        a reference (or variable), rather than a pointer.  Change
        the name to value_struct_elt_for_reference to reflect this.
        Returning a reference instead of a address provides a
        generalization, since we can use the routine for both
        class::name as well as &class::name.
        Also, recurse to handle multiple inheritance properly.
        * valprint.c:  Moved code to print pointer-to-members
        to new function point_class_member.  This allows a
        "reference-to-member" to be printed using the same code.
        * valprint.c (type_print_varspec_prefix):  Avoid printing
        "struct " for domains of class-member types.
        * valops.c (search_struct_field):  Inline code for simplified
        version of value_static_field (which can then be deleted).
        * value.h:  Rename value_struct_elt_for_address to
        value_struct_elt_for_reference.  Delete value_static_field.
        * values.c:  Remove no longer used function value_static_field.

        the xxxx_sym_fns vector to a standard format and add comments.
        * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
        elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):  
        Pass pointer to struct objfile rather than pointer to sym_fns.
        Change references inside each function accordingly.  Allocate any
        symbol file specific info in the per-objfile memory region.
        * dbxread.c (free_and_init_header_files):  Break function into
        free_header_files(), called from dbx_symfile_finish(), and
        init_header_files(), called from dbx_new_init().
        * dbxread.c (dbx_new_init):  Move deallocation things to new
        dbx_symfile_finish function.
        * elfread.c (elf_new_init):  Call buildsym_new_init().
        * objfiles.c (free_objfile): Call the appropriate symfile_finish()
        routine for the objfile before deallocating other stuff.
        * sparc-tdep.c (get_longjmp_target):  Cast target_read_memory arg.
        * symfile.h:  Move struct sym_fns to before struct objfile def.
        Add sym_finish function pointer and change prototypes of other
        function pointers to reflect passing struct objfile pointer rather
        than struct sym_fns pointer.
        * symfile.c:  Remove now obsolete symtab_fns pointer.
        * symfile.c (symfile_init):  Renamed to find_sym_fns, and now only
        locates the correct sym_fns struct for the given objfile.
        * symfile.c (syms_from_objfile, symbol_file_add):  Restructured
        for better support of mapped symbol tables.
        * symfile.c (symbol_file_command):  Remove obsolete code using
        symfile_fns.
        * symfile.h:  Remove duplicate declarations for symfile_objfile,

        * target.c (target_info):  Compare symfile_objfile to NULL.
        * xcoffread.c (aixcoff_new_init):  Move deallocation stuff to
        aixcoff_symfile_finish().

        * valprint.c (type_print_base):  Fix test for constructor.
        * values.c (value_static_field):  Allow evaluation of

        * symfile.c (syms_from_objfile): Eliminate local copy of bfd.
        * symfile.c (symbol_file_add):  Takes an additional arg (readnow).
        Change to eliminate local bfd and use symfile_bfd_open() plus
        allocate_objfile().  Add code to implement readnow option.
        * symfile.c (symbol_file_command): Changes to option handling,
        readnow functionality moved to symbol_file_add().

        value to iterate_over_msymbols().
        * xcoffexec.c (vmap_symtab):  Ignore return from iterate_over_
        msymbols().

Fri Mar  6 21:59:34 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in: added check target.

Thu Mar  5 23:56:01 1992  John Gilmore  (gnu at cygnus.com)

        * ecoff.c:  Move to ../bfd/coff-msym.c.
        * config/mt-*mips:  Remove ecoff.o from the configuration.
        * remote.c ():  Add newline to initial +.
        (remote_resume):  Mention how to cope with signals.
        (remote_interrupt):  Add debug msg.
        (remote-wait):  Implement new 'T' reply, which includes
        status, PC, and FP all in a single short message.
        (putpkt):  Add further debugging of packet acks.
        * mipsread.c (fixup_symtab):  Also swap RFD's.

        printing.
        * mips-pinsn.c (print_insn):  Byte-swap instruction.

Thu Mar  5 12:32:09 1992  Stu Grossman  (grossman at cygnus.com)

        * config.sub configure.in config/.Sanitize config/mh-irix4
        gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
        gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h
        gdb/xm-irix4.h gdb/config/.Sanitize gdb/config/mt-irix3
        gdb/config/mh-irix4 texinfo/configure.in:  Port to SGI Irix-4.x.

Wed Mar  4 11:56:42 1992  Fred Fish  (fnf@cygnus.com)

        * defs.h, utils.c:  xrealloc takes PTR as first arg.
        * defs.h:  Reword confusing comment about ANSI prototypes.
        * defs.h:  Some minor whitespace changes.
        * infrun.c (wait_for_inferior):  Compare int tmp to int 0,
        not NULL, which can be (void *).
        * tm-amix.h, tm-i386v4.h:  Add defines for setjmp/longjmp handling.
        * tm-i386v.h (SP_ARG0):  Define
        * xm-sysv4.h:  Back out of change for missing prototypes.
        * i386-tdep.c (get_longjmp_target):  Add function.

Wed Mar  4 05:46:11 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

        * Makefile.in: install man page too.

Tue Mar  3 15:11:52 1992  Michael Tiemann  (tiemann@cygnus.com)

        * All GDB files that #include defs.h: Removed stdio.h.
        (defs.h): #include stdio.h.

Mon Mar  2 23:00:12 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
        a ptype to reflect the setting of TARGET_PTR_BIT.  Set the
        TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
        * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
        * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
        it before printing out the hex shape of an address.

Sun Mar  1 17:41:09 1992  Per Bothner  (bothner@cygnus.com)

        * rs6000-xdep.c (frame_initial_stack_address):  Move
        code to set frame->cache_fsr into new separate function
        frame_get_cacahe_fsr.  This allows fixing a fatal error.
        * xcoffexec.c:  Turn previously suppressed error
        message back on, after cleaning up BFD.

        * breakpoint.c (breakpoint_re_set):  Removed (at least for now)
        printing of blank line, since it cases printing of an
        extra blank line.  Is this intended?  It does mess up
        gdb test suite.
        * defs.h:  Put back declarations of malloc and realloc,
        but protected by #ifndef MALLOC_INCOMPATIBLE.
        * objfiles.c:  Undo previous change:  Use malloc/realloc
        for objfile malloc/realloc fields (but add a cast).

Sat Feb 29 14:43:02 1992  Per Bothner  (bothner@cygnus.com)

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
        * buildsym.c: Use smash_to_pointer_type() to handle forward type
        references.
        * xcoffread.c: Modifications to C_DECL storage class handling, and
        introduction of an old smash_to_pointer_type() routine.

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
        * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
        parameters have been modified.

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
        * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
        and fetch_inferior_registers() always fetched all the registers
        resulting valid register values at hand all the time. Pushing a dummy
        frame did not require validating all register values first. After
        putting the above mechanism into action, we didn't have valid registers
        values always ready. Thus, all registers need to be fetched before
        pushing a dummy frame now.

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
        * rs6000-xdep.c: frame_initial_stack_address() function to calculate
        the starting address (actual frame address) of a frame.
        * rs6000-tdep.c: modifications to function_frame_info() to see if
        function reserves a frame pointer register (alloca register)
        * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
        FRAME_LOCALS_ADDRESS has been updated to support debugging of
        functions with alloca() calls.

Sun Mar  1 13:13:39 1992  Fred Fish  (fnf@cygnus.com)

        * xm-sysv4.h:  Provide definitions/prototypes for host environment
        functions for which no definitions or prototypes are provided in
        any currently included gdb or host environment header files.
        For SVR4, this currently includes malloc and realloc, which cannot
        be portably prototyped in any gdb include file.

Sat Feb 29 14:43:02 1992  Per Bothner  (bothner@cygnus.com)

        * buildsym.h:  Remove obsolete variable file_stabs.

        * Makefile.in:  Move place where configure merges in host-
        and target-dependent fragments later, so the latter
        can override (say) GNU_MALLOC.
        * config/mh-rs6000:  Use system malloc.  Otherwise, I
        ended up with *two* incompatible versions of malloc
        (functions in libc would call the malloc in libc).
        I assume this is a shared library problem.

        * remote.c:  Fix (presumed) typo.
        * objfiles.c:  Use xmalloc/xrealloc instead of
        malloc/realloc (since the latter are no longer declared).

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
        * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
        handle individual registers.
        * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
        correctly in case it wasn't cached yet. (A problem showed up
        after fetching individual registers.)
        * buildsym.c: Disable type_synonym_name's type name overwriting
        in cases it is unnecesary. rs6000 portation doesn't use
        type_synonym_name, and it used to nullify type names
        * xcoffread.c: to handle g++'s typename abbreviation, fill in a
        type's name as soon as space for that type is allocated.
        * xcoffread.c: ignore a section's lineno information if it is
        not `.text'. (In rs6000 bfd portation integration, skipping over
        `.pad' sections are ignored since it was in machine independent
        part of the code. Thus, a problem of fake sections with invalid
        lineno information arised.)

        Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
        [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
        * rs6000-tdep.c: make function_frame_info() work whether or not
        reading from a core file.
        * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.

        * infrun.c. main.c, printcmd.c. symtab.c:
        More changes from IBM for rs6000.


Thu Feb 27 22:57:19 1992  Per Bothner  (bothner@cygnus.com)

        * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
        rs6000-xdep.c, xcoffexec.c, xcoffread.c:
        Merge in changes (mostly from IBM) for RS6000.
        * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
        More changes from IBM for RS6000.  These are in machine-
        independent code, and probably could do with some cleaning
        up.  The most questionable of these are #ifdef IBM6000.
        * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
        to single_step() (for consistency with rs6000 and i860).
        * utils.c:  Allow the 1st arg to xrealloc to be NULL
        (in which case do malloc).  This removes the need for
        some tests in xcoff code (and perhaps other places?).
        * coffread.c: Removed variables last_source_file,
        type_vector, and type_vector_length as these are now
        defined by buildsym.[ch].
        * defs.h:  Remove prototypes for malloc and realloc, since
        these should only be used to implement xmalloc and xrealloc,
        and they conflict with <stdlib.h> in AIX - where they
        return void* even when __STDC__ isn't defined.  Sigh.
        * munch:  Recognize *initialize* in data as well as text
        (AIX uses data).  Also, incorporate a patch from Garrett
        Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
        much more sensible, by only trying to match the name of
        the initialize_foo function, and not the junk before it.
        
Thu Feb 27 20:07:43 1992  Stu Grossman  (grossman at cygnus.com)

        * breakpoint.c (breakpoint_re_set_one):  Don't reset breakpoint
        unless symbol table indicates that something has changed.

Thu Feb 27 11:48:47 1992  John Gilmore  (gnu at cygnus.com)

        * remote.c:  Make it work for embedded MIPS.  Increase buffer
        size, and use throughout.  Round buffer size up if too many regs.
        Support baud rate setting and try for an 8-bit path.  If
        interrupted while waiting for target, send a ^C down the wire.
        Avoid single-byte reads.
        * tm-mips.h:  Add more embedded-system registers to REGISTER_NAMES
        and NUM_REGS.
        * mips-xdep.h:  Avoid the embedded regs when on Unix.

        * mipsread.c:  Byte-swap the symbol table structures, using
        routines from ecoff.c, to read a symbol table written in any
        of the four possible byte orders.
        * configure.in (mips-big-* target):  Same as Sony News.
        * config/mt-bigmips, config/mt-littlemips:  Add ecoff.o.
        * ecoff.c:  New file for symbol swapping routines.

Thu Feb 27 09:26:38 1992  Stu Grossman  (grossman at cygnus.com)

        * breakpoint.c (all_breakpoints_info, breakpoint_1):  Add 'info
        all-breakpoints' command.
        * (get_number):  Allow users to enter negative breakpoint numbers.
        * (breakpoint_1):  Reformat display of 'info break' to show new
        fields.
        * (create_longjmp_breakpoint, breakpoint_re_set,
        breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
        symfile.c  (syms_from_objfile):  Re-do
        insertion of longjmp breakpoints.  Move all code into
        breakpoint_re_set, and call that instead of
        create_longjmp_breakpoint in symfile.c.

Thu Feb 27 06:11:05 1992  John Gilmore  (gnu at cygnus.com)

        * breakpoint.h (ALL_BREAKPOINTS_SAFE):  Add.

        * infcmd.c:  Fix comment.
        * objfiles.c (free_all_objfiles):  Add.
        * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE):  Add.
        * symfile.c (symbol_file_command):  free all objfiles when
        specifying a new symbol file.
        (reread_symbols):  Stat the file name, don't fstat the descriptor.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in, configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

Tue Feb 25 19:31:19 1992  Stu Grossman  (grossman at cygnus.com)

        * dbxread.c (end_psymtab):  Delete empty psymtabs.
        * symfile.c (allocate_psymtab):  Recycle empty psymtabs.
        * symfile.h (struct objfile):  Add free_psymtabs.

        * breakpoint.h:  Move prototypes to follow enum definition they need.
        * breakpoint.c, infrun.c:  Lint.
        * printcmd.c:  Use `enum enable' rather than `enum
        display_status'.
        * mipsread.c:  First pass at making it compile with the new
        objfile changes.  Probably seriously broken still, but it
        compiles.  FIXME.

Sat Feb 22 00:56:39 1992  Stu Grossman  (grossman at cygnus.com)

        * infrun.c, infcmd.c, breakpoint.c, main.c, symfile.c,
        breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
        mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h:  Add support for
        stepping (and nexting) through longjmp().  Also, cleanup
        breakpoint handling quite a bit by creating explicit breakpoint
        types instead of using magic breakpoint numbers.
        Makefile.in:  Update version to 4.4.3

Sat Feb 22 00:08:50 1992  John Gilmore  (gnu at cygnus.com)

        * buildsym.c, dwarfread.c, gdbtypes.c, inflow.c, main.c,

        * minsyms.c (install_minimal_symbols):  Add bunches to any
        existing minsyms in the objfile.  Avoid extra mallocation
        by working directly in the obstack.  Remove ignored `mainline' parm.
        * coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
        xcoffread.c:  Change all callers.
        * FIXME:  We should be able to eliminate MAINLINE from all the
        symbol readers now, with a small bit of work.

        * valops.c, value.h:  Lint.
        * remote-vx.c:  Add missing break; statement.  Bugfix by
        Michael Sclafani, <sclafani@src.dec.com>.

        * buildsym.h:  Convert function decl's to prototype form.
        * c-exp.y:  Add prototypes for local functions, convert uses of misc
        function vector to minimal symbol table.  Reformat all builtin type
        initializations and pass a NULL objfile to init_type() for them.
        * coffread.c:  Change context_stack ref's to coff_context_stack,
        add local function prototypes.  Cast uses of xrealloc arg 1.

        * dwarfread.c (process_dies):  Add case to handle TAG_pointer_type
        DIE's.  Add new function read_tag_pointer_type() to read them.

        * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
        When creating a new user defined type, check to see if a partial
        type already exists, and if so, bash it to fit.

Fri Feb 14 19:00:17 1992  John Gilmore  (gnu at cygnus.com)

        * coffread.c (decode_base_type):  Pass long, not union.
        Fix by Eric Valette, ev@chorus.fr.

Thu Feb 13 17:14:28 1992  Fred Fish  (fnf at cygnus.com)

        * elfread.c (elf_symtab_read):  Fix code to correctly track
        changes in bfd for absolute symbols.

Thu Feb 13 12:43:29 1992  Stu Grossman  (grossman at cygnus.com)

        * xm-vaxbsd.h:  Close off comment.

Thu Feb 13 07:45:19 1992  Fred Fish  (fnf at cygnus.com)

        * xm-sysv4.h:  Define NEED_POSIX_SETPGID.

Fri Feb  7 11:51:12 1992  Per Bothner  (bothner at cygnus.com)

        * mips-tdep.c (mips_print_registers):  Print correct register
        number for double pseudo-registers.

Fri Feb  7 07:56:05 1992  John Gilmore  (gnu at cygnus.com)

        * buildsym.c (read_struct_type):  Avoid double-bump of parse ptr
        in the op$::OPERATOR. case.  From Steven McCanne,
        <mccanne@horse.ee.lbl.gov>.

        * exec.c (set_section_name):  Pass arg to exec_files_info;
        only call it if interactive.  From Francis Kauth <fk@tv.tv.tek.com>.

Thu Feb  6 17:41:32 1992  John Gilmore  (gnu at cygnus.com)

        * main.c (print_gdb_version):  Copyright msg: only this year.
        (cd_command):  Avoid changing current_directory on error.

Thu Feb  6 15:14:01 1992  Per Bothner  (bothner at cygnus.com)

        * mipsread.c (parse_partial_symbols):  Handle dependencies
        between partial symbol tables (when not doing stabs-in-ecoff).
        (This used to be handled by parse_fdr, but parse_fdr was
        incompatible with handling stabs-in-ecoff, so the code
        was re-written to not use parse_fdr.  Unfortunately,
        the logic to handle dependencies was overlooked.)

Thu Feb  6 11:51:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * coffread.c (read_enum_type): Use the size of a target int when
        describing enum.
        * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
        of target int.
        * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
        * symtab.c (lookup_reference_type, lookup_ptr_type): use
        TARGET_PTR_BIT to determine size of a pointer
        * values.c (unpack_long): when unpacking a REF or a PTR don't
        assume the size of the type.

Wed Feb  5 22:29:59 1992  John Gilmore  (gnu at cygnus.com)

        * mipsread.c (parse_symbol):  Avoid clobbering enum pointer when
        looking at its members.  Improve guess between struct and union,
        only assuming union if multiple members have offsets of zero.

Tue Feb  4 18:05:44 1992  Per Bothner  (bothner at cygnus.com)

        * mipsread.c:  Use (FP0_REGNUM-32) instead of magic number 6.
        (This is just for clarity - and one day permitting us to
         change FP0_REGNUM from 38 to 32, which would make more sense.)
        * tm-mips.h:  Added STAB_REG_TO_REGNUM macro, so that
        register numbers in stabs-in-ecoff get handled correctly.

Sat Feb  1 04:45:10 1992  Stu Grossman  (grossman at cygnus.com)

        * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
        config/mh-vaxbsd, configure.in:  Split up config stuff for Vaxen
        into BSD and Ultrix.

Sat Feb  1 04:39:41 1992  John Gilmore  (gnu at cygnus.com)

        * dbxread.c (dbx_symfile_init):  Call malloc, not xmalloc.

Sat Feb  1 04:15:41 1992  Stu Grossman  (grossman at cygnus.com)

        * Makefile.in:  Increment version to 4.4.1.
        * main.c (print_gdb_version):  Update copyright notice.

Sat Feb  1 01:43:11 1992  Per Bothner  (bothner at cygnus.com)

        * mipsread.c:  Prepend "struct " to the names of structure
        types, and similarly for enums and unions.  (This used
        to be done, but got lost in the re-write to "guess" the
        difference between enum/struct/union.)
        Also, guess that a tag is an enum if the first member
        has type btNil.

Fri Jan 31 21:45:51 1992  Stu Grossman  (grossman at cygnus.com)

        * xm-vax.h:  #ifndef ultrix around #include of endian.h and
        limits.h (sigh).

Fri Jan 31 00:05:01 1992  John Gilmore  (gnu at cygnus.com)

        * Projects:  Patching executables is done.
        * Makefile.in (VERSION):  Roll to gdb-4.4.
        * README, WHATS.NEW:  Update for gdb-4.4.

        * symfile.c (reread_symbols):  Whenever we reread one object
        file's symbols, we must restart the scan, because the object_files
        chain has been permuted.

        * exec.c (exec_files_info):  Split out into print_section_info.
        Print BFD filename of each section if it's not the default one.
        * core.c (core_files_info):  Call print_section_info.

        * xm-vax.h:  Include a few system header files whose definitions
        must precede defs.h.
        * language.c, language.h:  Make some things const.
        * expression.h, main.c:  const spreads like ooze.

        * mem-break.c (break_insn, break_insn_size):  Use unsigned chars,
        since BREAKPOINT values can be >0x80.

Thu Jan 30 17:21:14 1992  Stu Grossman  (grossman at cygnus.com)

        * infrun.c, xm-i386sco.h:  SCO needs to use setpgid().

Thu Jan 30 01:04:23 1992  John Gilmore  (gnu at cygnus.com)

        * sparc-pinsn.c:  Remove kludge for preferring architectures.
        Remove #ifdef's for SORT_NEEDED.  We need to sort the table, now
        and forever.  Add `add' instruction to the set that get checked
        for a preceding `sethi' in order to print an absolute address.
        Corresponding changes in ../include/opcode/sparc.h needed
        to eliminate garbage instructions.

Wed Jan 29 19:24:34 1992  Per Bothner  (bothner at cygnus.com)

        * mipsread.c (parse_partial_symbols):  Make sure partial
        symbols are created for external symbols (as used to be
        the case).  This is a bit of a pain with the mips-coff.
        It uses a table which points to all of the external
        symbols belonging to a particular FDR or psymtab.
        Once we've generated this table, we might as well save
        it, and then use it in psymtab_to_symtab_1 to find
        the symbols to pass to parse_external().
        * symfile.c,  symfile.c:  New function start_psymtab_common
        to share the common parts of allocating a new psymtab
        for dbxread, mipsread (and later dwarfread).  Its code
        was pulled out from start_psymtab in dbxread.c.
        * dbxread.c (start_psymtab):  Use start_psymtab_common().

        * valprint.c (val_print):  If there is an error when trying
        to print a string, check to see if there really is a problem
        by reading just one character.  If that works, assume
        things are ok.

Wed Jan 29 18:58:43 1992  Stu Grossman  (grossman at cygnus.com)

        * sparc-pinsn.c (compare_opcodes):  Make it prefer v6, v7,
        cypress, v8 mnemonics in that order.

Tue Jan 28 17:32:13 1992  Per Bothner  (bothner at cygnus.com)

        * sparc-pinsn.c:  Put the qsort() back in.

Mon Jan 27 18:51:03 1992  John Gilmore  (gnu at cygnus.com)

        * findvar.c (read_register, write_register):  Handle machines
        where REGISTER_TYPE is not the same size as "int".

        Handle debug symbols in dynamically loaded (relocated) code:

        * dbxread.c (read_ofile_symtab):  Fix up N_CATCH better.  Pass
        offset to process_one_symbol.
        (process_one_symbol):  Take new offset parameter.  Add it into
        appropriate symbol types to relocate symbols to loaded addresses.
        Handle all possible symbol types, and complain() about types that
        we don't expect to see.
        * mipsread.c (psymtab_to_symtab_1):  Pass offset of zero to
        process_one_symbol (FIXME, should pass real offset).

        Misc bugfixes:

        * breakpoint.c (resolve_sal_pc):  Split out code to resolve a
        sal's PC value.
        (set_breakpoint, break_command_1, until_break_command,
        catch_command_1, breakpoint_re_set_one):  Use it.
        * symtab.h (resolve_sal_pc):  Declare.
        * infcmd.c (jump_command):  Use resolve_sal_pc.

        * source.c (list_command):  Shorten "FILE, line N" to "FILE:N".

        * putenv.c (putenv):  Avoid unportably casting pointers to unsigneds.

        * c-exp.y (yylex):  `this' and `template' are only tokens in C++.

        * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
        xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
        Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.

Mon Jan 27 15:46:21 1992  Stu Grossman  (grossman at cygnus.com)

        * dbxread.c (process_one_symbol):  Make a first cut at handling
        symbol tables generated by Sun's acc.  (#ifdef'd out, FIXME.)

        * symtab.c (find_pc_line):  Fix stepping into and out of #included
        files.

Mon Jan 27 13:00:55 1992  Stu Grossman  (grossman at cygnus.com)

        * Makefile.in (OPCODES):  Remove OPCODES defs and refs.  There is
        no longer any need to copy ../include/opcode/* into gdb.

Mon Jan 27 12:30:38 1992  John Gilmore  (gnu at cygnus.com)

        * ChangeLog, ChangeLog-9091:  Split ChangeLog at 1992.

Sun Jan 26 19:05:40 1992  Per Bothner  (bothner at cygnus.com)

        * valprint.c (type_print_base, type_print_method_args):
        Print C++ constructor methods without bogus "return type."

Sat Jan 25 15:57:59 1992  Fred Fish  (fnf at cygnus.com)

        * infptrace.c (child_xfer_memory):  Parameter "target" should
        be a pointer to a structure, not the entire structure.

Fri Jan 24 01:30:27 1992  Fred Fish  (fnf at cygnus.com)

        * depend:  Convert the couple of references to ansidecl.h that
        used the local gdb version to use the ../include version.

Thu Jan 23 22:24:43 1992  Fred Fish  (fnf at cygnus.com)

        * procfs.c
        (child_xfer_memory): Takes pointer to a struct, not entire struct.
        (inferior_proc_init):  Fix non-ANSI version of args.
        (attach):  Call print_sys_errmsg with correct number of args.
        (mappingflags):  Make static, does not need to be global.

        * i386-tdep.c (i386_frame_num_args):  Takes a pointer to a struct
        not the entire struct itself.

        * valops.c (value_assign):  Cast some args to modify_field() and
        {read,write}_register_bytes() correctly.

        * ansidecl.h:  Removed, is duplicate of ../include/ansidecl.h

        * Makefile.in (MALLOCSRC):  Removed reference to removed local
        copy of ansidecl.h.

        * dwarfread.c (list_in_scope):  Needs an initial value, use file
        scope.

Mon Jan 20 19:06:28 1992  Stu Grossman  (grossman at cygnus.com)

        * main.c (main):  Make option_index local to keep new getopt happy.
        main.c, solib.c, Makefile.in:  Update copyright notices.

Mon Jan 20 08:54:00 1992  Michael Tiemann  (tiemann at cygnus.com)

        * cplus-dem.c (cplus_demangle): Correctly demangle destructors.

Sat Jan 18 17:17:45 1992  Stu Grossman  (grossman at cygnus.com)

        * Makefile.in (HFILES):  Add partial-stab.h.

Sat Jan 18 16:45:01 1992  Fred Fish  (fnf at cygnus.com)

        * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
        New files for stratus.  Not complete enough to actually build
        on the Stratus machine; that awaits copyright assignment for
        i860 changes.

        * Makefile.in (USER_CFLAGS):  Add macro specifically reserved
        for getting custom flags into CFLAGS when doing makes.

        * configure.in:  Add config information for stratus.

Thu Jan 16 00:51:46 1992  Fred Fish  (fnf at cygnus.com)

        * dbxread.c (process_one_symbol):  Pass address of structure
        to complain(), rather than the whole structure.

Wed Jan 15 09:56:16 1992  Fred Fish  (fnf at cygnus.com)

        * solib.c (solib_add_common_symbols):  Only compile in when not
        using SVR4 style shared libraries.

Tue Jan 14 22:34:00 1992  Fred Fish  (fnf at cygnus.com)

        * dwarfread.c (locval):  Add offreg flag to indicate location
        values that are computed off a base register.

        * dwarfread.c (new_symbol):  Rework TAG_global_variable and
        TAG_local_variable cases to account for static variables
        within function scopes.

Tue Jan 14 12:28:52 1992  Stu Grossman  (grossman at cygnus.com)

        * inflow.c:  remove #include <sys/dir.h>.  Not necessary, and
        doesn't exist on some systems.

        * infrun.c (wait_for_inferior!!!!):  Prevent gdb from hanging when
        nexting over recursive function calls.

        * target.c (target_read_string):  Create this routine to read null
        terminated strings from the target.  It deals with running off the
        end of memory elegantly as well.  solib.c (find_solib):  Use
        target_read_string() to avoid problems with running off the end of
        memory.

        * inflow.c (child_terminal_info):  #ifdef TIOCPGRP around lines
        that reference pgrp_inferior.

Mon Jan 13 14:57:11 1992  Per Bothner  (bothner at cygnus.com)

        * tm-mips.h:  Removed BLOCK_ADDRESS_ABSOLUTE, now that
        mips-tfile has been hacked to act more "traditionally."
        * dbxread.c:  Fixed typo in comment.

Sun Jan 12 13:08:36 1992  Per Bothner  (bothner at cygnus.com)

        * mips-tdep.c (mips_skip_prologue):  Add some number of
        'sw' instructions before 'addiu' adjusts the stack.

Fri Jan 10 13:47:06 1992  Fred Fish  (fnf at cygnus.com)

        * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
        freescope, buildblock closescope, record_line, add_symbol_to_list,
        gatherblocks, make_blockvector):  Extensive changes to switch
        to generic symbol table building code in buildsym.c.  Remove
        scope tree structures and functions, symbol table building
        functions, and lots of other small changes.

        * dwarfread.c:  Add new macros GCC_PRODUCER and STREQN.  Remove
        GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.

Tue Jan  7 13:09:57 1992  Stu Grossman  (grossman at cygnus.com)

        * buildsym.c (cleanup_undefined_types):  Add support for enums.
        This fixes the 'GDB internal error.  cleanup_undefined_types with
        bad type' problem.

Sun Jan  5 09:47:50 1992  Stu Grossman  (grossman at cygnus.com)

        * dbxread.c:  detect gcc2 compilations.

Thu Jan  2 15:07:41 1992  John Gilmore  (gnu at cygnus.com)

        * sparc-pinsn.c:  Rename bitfields that overlap with macro names
        in ../include/opcode/sparc.h.

Wed Jan  1 04:29:00 1992  Fred Fish  (fnf at cygnus.com)

        * Makefile.in:  Change tm-svr4.h to tm-sysv4.h.  Change xm-svr4.h
        to xm-sysv4.h.  Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
        to reflect actual locations of opcode files, so TAGS target will
        be buildable.

        * i386-tdep.c:  Change an erroneous 'm68k' reference to 'i386'.

        * i386-tdep.c (supply_fpregset, fill_fpregset):  Remove m68k
        code.

        * m68k-tdep.c (supply_fpregset, fill_fpregset):  Fix array
        dereferencing to access the correct elements.

        * valops.c (value_addr):  Declare return type of external func
        value_copy().

        * xcoffread.c:  Undefine next_symbol_text before redefining it.
