Correct misconception that there can be only one symbol table.
Only call elf_slurp_symbol_table on the full symbol table, not
the dynamic one which is only a subset of the full one.
(The bfd library was slurping in the first ELF symbol table it
found and then ignoring any others. For dynamically linked
executables, this happened to be the dynamic symbol table, which
is a subset of the full symbol table and only contains the
symbols that need to be used in dynamic linking.)
* xm-sun3os4.h: Define MALLOC_INCOMPATIBLE to avoid conflicts
with decls of malloc in c-exp.tab.c (as produced by yacc).
There's got to be a better way to do this...
* mipsread.c, dbxread.c: Remove troublesome inclusion of non-
standard <strings.h> file, now that the only single use of
rindex in the gdb source files is gone.
which #defines index to be strchr. Unfortunately, index is
a member of a symbol table structure that can't be changed.
* mipsread.c: tm-mips.h includes coff/symconst.h and coff/sym.h,
remove redundant #include's.
Various changes to get linker working again for a.out:
* don't set/adjust section file positions or vmas more than once
* use correct page size and segment size when calculating them
* deal with some variations in a.out implementations
Tested on sun4 and sun4->sun3 so far, will be testing further but
needed to get wider exposure&testing. See ChangeLog for details.
Also:
* coffcode.h (coff_write_relocs): Write out swapped reloc, not
pre-swapped version.
* hosts/sparc.h (abort, exit): Hide these names if compiling with
gcc version 2, to avoid warnings.

* hosts/sparc.h (abort, exit): Hide these names if compiling with

* symtab.c (decode_line_1): Until C++ support stabilizes, when
C++ lookups fail, print possibly helpful hint about completion.
* cplus-dem.c (demangle_signature): Fix ARM style demangling
for static data members.
* dbxread.c (dbx_psymtab_to_symtab_1): Fix prototype.
* config/ncr3000.mh (INSTALL): Don't use /usr/ucb/install,
it's broken on ncr3000's.
Change 'modifier' to char from unsigned char. Cast single use
that needs to be unsigned char.
* symtab.h (SYMBOL_BASEREG_VALID): Explain disabling.
* utils.c (strdup_demangled): Add function.
* defs.h (strdup_demangled): Add prototype.
* stack.c (return_command): Demangle C++ function names for query.
* infcmd.c (jump_command): Demangle C++ function names for query.
* cplus-dem.c (consume_count): New function and prototype.
* cplus-dem.c (demangle_class, gnu_special, demangle_func_type,
do_type): Replace conversion code with consume_count().
* cplus-dem.c (gnu_special): Fix demangled of static members.
* source.c (list_command): Print demangled function names
when appropriate. Fix supplied by Peter Schauer.
* xm-sun4sol2.h (gregset_t): Thinko in register set definition.
* symtab.h: Disable SYMBOL_BASEREG_VALID until it works.
* dbxread.c (dbx_psymtab_to_symtab_1): Renamed from
psymtab_to_symtab_1. Use current psymtab's sym_offset and symbol_size,
rather than the one for the first file in the dependency chain.
ugly changes in signal blocking macro. Use them throughout,
reducing #ifdef HAVE_POSIX_SIGNALS and HAVE_BSD_SIGNALS clutter
significantly. Make all such places use POSIX if available,
to avoid losing with poor `sigsetmask' emulation from libiberty.
set. Don't reset our own texthigh, or dependency-only pst's, in
scanning all the rest of the psymtabs.
(process_one_symbol): Fix comments around N_OBJ, N_OPT, N_UNDF.
* buildsym.h (N_UNDF): Improve comments.
(N_LSYM, etc): Skip types without names (":T(0,3)=sfoob...").
an additional per-symbol value.
* symtab.h (SYMBOL_BASEREG, SYMBOL_BASEREG_VALID): Add defines.
* frame.h (FRAME_GET_BASEREG_VALUE): Provide default definition.
* findvar.c (read_var_value): Use SYMBOL_BASEREG if valid.
* printcmd.c (address_info): Use SYMBOL_BASEREG if valid.
* symmisc.c (print_symbol): Use SYMBOL_BASEREG if valid.
extra info in the minimal symbol.
(elf_symtab_read): The extra info is the size of an ELF object,
which was kludged to us in the `udata' field of the BFD symbol.
Gag me with a crowbar...
(elf_symfile_read): Keep track of both the absolute load address,
and the offset between load addr and symbols. Handle STABS as
well as DWARF sections, passing the absolute load address to
elfstab_build_psymtabs.
* objfiles.c (free_objfile): Eliminate storage leaks. Contributed
by <Peter.Schauer@regent.e-technik.tu-muenchen.dbp.de>.
* symfile.c (symfile_bfd_open): Comment where name is freed.
* symmisc.c (extend_psymbol_list): Comment where list is freed.
Add symbol_size and file offsets to struct symloc.
Add static symbol_table_offset, string_table_offset,
file_string_table_offset, next_file_string_table_offset,
last_function_name.
(add_old_header_file): Convert error() to complain()t.
(dbx_symfile_read): Get symbol size via the objfile.
Also get symbol_table_offset.
(dbx_symfile_init): Record symbol size and count via the objfile.
(dbx_next_symbol_text): Always add file_string_table_offset when
accessing string table.
(read_dbx_symtab): Initialize file_string_table_offset to 0.
(SET_NAMESTRING): Use the offset.
(end_psymtab): Large kludge to determine addresses where source
files start and end (for the psymtab header).
