    * 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

    * xcoffsolib.c, xcoffsolib.h:  New files, from Metin.
    * Various files: Changed #ifdef IBM6000 to IBM6000_HOST
    or IBM6000_TARGET as (approximately) appropriate.

Sat Mar 28 13:00:10 1992  Fred Fish  ([e-mail])

    * objfiles.h (OBJF_SYMS):  Define flag bit for objfile flags.
    * symfile.c (symbol_file_add):  Use OBJF_SYMS to decide  whether

    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

    * 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

    * dbxread.c (init_psymbol_list):  Use DBX_SYMCOUNT.
    * dbxread.c (dbx_psymtab_to_symtab):  Remove local stringtab and
    stringtab size variables.  Remove all code that used to reread

    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  ([e-mail])

    * rs6000-pinsn.c:  Make dis-assembly output more like
    other targets:  Don't print instruction in hex before

    * 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.)

Tue Mar 24 23:27:01 1992  K. Richard Pixley  ([e-mail])

    * mipsread.c (fixup_sigtramp):  Make sure that current_objfile is setup
    when calling new_symbol.
    * mips-tdep.c (mips_frame_chain):  Use symfile_objfile instead of
    current_objfile.

Tue Mar 24 13:26:25 1992  Per Bothner  ([e-mail])

    * config/rs6000.mh:  Update (for Fred's new mmalloc)

Thu Mar 19 18:49:45 1992  Per Bothner  ([e-mail])

    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.

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

Wed Mar 18 18:22:46 1992  Fred Fish  ([e-mail])

    introduction of an old smash_to_pointer_type() routine.

    Changes from [e-mail] (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 [e-mail] (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 [e-mail] (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  ([e-mail])

    * 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  ([e-mail])

    * 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 [e-mail] (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 [e-mail] (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  ([e-mail])

    * 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 <[e-mail]> 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

    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.

    * (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.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  ([e-mail])

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

    * 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.

    * coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
    xcoffread.c:  Change all callers.

    symbol readers now, with a small bit of work.

    * remote-vx.c:  Add missing break; statement.  Bugfix by

    target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
    Remove to_call_function and target_call_function, since it

    to_sections, etc.
    * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,

    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, [e-mail].

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.
