stratus that are not yet in release pending receipt of paperwork
at FSF.

* gdbtypes.h (struct field): Add to comments.
* gdbtypes.h (virtual_field_bits): Add to comments.
* objfiles.c (allocate_objfile): Change obstack interface to
match FSF merging efforts.
with alloca, to avoid using random values from stack later on.
* defs.h (fprintf_filtered): Add prototype.
* gdbtypes.c (check_stub_method): Fix misleading comments.
* gdbtypes.c (print_arg_types, dump_fn_fieldlists): New maint
support functions.

small changes to maint support functions.

for some fields and expand comments.

macro and track change to obstack_full_begin macro.
* utils.c (fprintfi_filtered): New function.
* valprint.c (type_print_base): Fixup field printing to not
print extraneous lines and not print bogus "no data fields"
messages for C++ classes with no data members. Also use new
fprintfi_filtered function.
to create new blank types, instead of handcrafting them.
* defs.h (printfi_filtered): Add prototype.
* utils.c (printfi_filtered): New function.
* gdbtypes.c (recursive_dump_type): Use printfi_filtered to
to simplify the code. Other cleanups.
* gdbtypes.c (check_stub_method): Demangle using DMGL_ANSI.
* gdbtypes.h (struct cplus_struct_type): Add comments describing
use of various fields.
* gdbtypes.c (print_bit_vector, print_cplus_stuff): New functions.

production that currently treats it exactly the same as STRUCT.
* c-exp.y (yylex): Recognize "class" as token CLASS.
* symtab.c (gdb_mangle_name): Rewrite to match current g++ stabs.
* symtab.c (decode_line_1): Fix to pass quoted args on down to
general symbol handling code. Call cplus_mangle_opname with
DMGL_ANSI.
* symtab.c (decode_line_2): Print demangled function names in
breakpoint menus, instead of just file and line number.
* symtab.c (name_match): Call cplus_demangle with DMGL_ANSI.
* valprint.c (type_print_base): Print "class" for C++ classes,
rather than "struct". Print section labels for public, protected

child processes, to avoid dead ones "hanging around" after GDB exits.
(attach): Always stop the process if it needs it. Set RLC flag
when attaching running processes, so it will continue if we detach
it, quit, or are killed.
(detach): Clear faults and set RLC flag to make process run
when we close it.
(open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.

* partial-stab.h: Ignore N_ENDM.
* elfread.c (elf_symtab_read): Ignore symbols that don't have a
CODE or DATA section attachment. This eliminates a lot of random
values from shared libraries, which screw up the ordinary symbols
in the address ranges they happen to overlap.
* buildsym.c (define_symbol): Eliminate special tests
for function types; move into "function" cases in switch statement.
(define_symbol: 'f', 'F', 'P'): Process all parameter types
in case they define new type numbers. But ignore them (FIXME).
('k', 'B'): Ignore const and volatile if we see them (FIXME).
(read_sun_builtin_type): Add commentary.
Fix from Jim Williams.
* stack.c (return_command): Evaluate expression *before* popping
off the stack frames! Fix inspired by Jim Williams.
(up_silently_command, down_silently_command): No sel frame is error.
* defs.h (memcpy, memset): Conditionalize decls on
#ifndef MEM_FNS_DECLARED, since DECstation differs.
(alloca): Break out the STDC and non-STDC alloca cases, to make
it work on old preprocessors as well as "picky ANSI" ones.
* xm-mips.h (memcpy, memset): Declare, and set MEM_FNS_DECLARED.
* mips-tdep.c (heuristic_proc_start): Zero arg produces zero.
* utils.c (fputs_demangled): Rename SLOP since DECstation system
header files define it!
symtab.h, tm-i386v4.h, valprint.c, values.c: Lint.

Replace bcopy() use with memcpy(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.

ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,

Replace bzero() use with memset(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
* i386-tdep.c, main.c, valprint.c:
Replace bcmp() use with memcmp(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
C++ syms as demangled, not just functions.
* buildsym.c (read_range_type): When we find a signed char
type, do a lookup of signed char, not plain char. Plain char's
still get looked up as plain char's elsewhere.
* buildsym.c (read_sun_builtin_type, read_sun_floating_type): New.
(define_symbol): Skip arg types in function entries. Resolve
overloaded 'P' which acc uses for prototypes of functions called
by this file.
(read_type: 'b', 'r'): Handle Solaris2 builtin types.
* minsyms.c (prim_record_minimal_symbol_and_info): Hack to
save size of ELF symbols. FIXME.
* tm-sun4os5.h: Rename to tm-sun4sol2.h. Update defines for Sol2.
* xm-sun4os5.h: Rename to xm-sun4sol2.h. Hack more defines.
* config/sun4os5.m[ht]: Rename to config/sun4sol2.m[ht]; new xm, tm.
functions which handle overwriting of forward-referenced types
for stabs file reading.
(lookup_{reference,pointer,function}_type): These just call
the make_*_type functions with a null storage alloc parameter.
* gdbtypes.h (make_{reference,pointer,function}_type): Declare.
* xcoffread.c (smash_to_pointer_type): Remove, no longer used.
* buildsym.c (dbx_lookup_type): Zero result for (-1,-1) arg.
(dbx_alloc_type): Make it easier to understand. No funct change.
(define_symbol: 't'): Don't put the typedef name into the name of
the struct, union, or enum. Bugfix.
(read_type: '*', '&', 'f'): Add comments. Use make_XXX_type
routines to properly handle overwriting preallocated types so that
forward references will work.
(read_enum_type): Force enum values to file scope, due to bug in
Sun compiler output. FIXME, fix later.
Remove unused header_file_prev_index mechanism. It was already
obsolete in gdb-3.5. These comments appeared in 3.5:
/* This code was used before I knew about the instance codes.
My first hypothesis is that it is not necessary now
that instance codes are handled. */
* dbxread.c (add_new_header_file): Remove header_file_prev_index.
* buildsym.h: Remove it and prev_index that saves it.
* buildsym.c (push_subfile, pop_subfile, start_symtab): Remove it.
* solib.c (special_symbol_handling): When called from core files,
must set up debug_addr. Don't print error messages, just return.
* symmisc.c (print_symbol): Less ascii diarrhea for enums, please.
abbreviated type name is messed up. Reported by Joe Buck.
FIXME, we need to determine whether GDB or GCC needs to be
smarter to correctly locate this type name. p*927 circumvention,
needs real fix when Tiemann's back.
basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
Made some more progress in removing duplicate assembly opcode files.
More improvements to how mipsread and to a lesser extent dbxread work.
See the ChangeLog for details.
stub methods. These changes are not complete in that a better
implementation will be more maintainable, but they make it possible to
debug groff with GDB.
