4a11eef2eb Add TYPE_FLAG_FUND_TYPE bit to the flags member of the type structure,
and use it to decide when to print the actual type name rather than
trying to invent the name of a fundamental type.  This clears up the
confusion between int/long when they are the same sizes, removes one
obstacle to multi-language support (previously valprint.c thought
everything was a C type), and allows gdb to support distinctions between
explicitly and implicitly signed types when the compiler supports such
distinction in the debug output (as does every ANSI compiler I tested
except for gcc).

817bc7b82a * mipsread.c (parse_partial_symbols): Complain when sh->index is
too high or when skipping `forwards' moves us backwards.
	(parse_type):  Print mis-guessed tag name in complaint.
	(parse_external):  Eliminate cur_stab and obscure top_stack clobbers.
	(parse_procedure):  Do not attempt to create symbols; just fill in
	the SYMBOL_VALUE field of a .gdbinfo. symbol if we can find one.
	(psymtab_to_symtab_1):  Split up `stabs' from `native ecoff' code
	for clarity.  Set top_stack before calling parse_external.  In
	stabs, sort symbols before calling parse_procedure.
	* mipsread.c:  Lint.
	* symmisc.c (std_in, std_out, std_err):  Add vars to access std
	FILE *'s when debugging GDB (e.g. as args to dump_symtab).
	* Makefile.in:  Remove stage* targets.  Avoid echo on recursive
	makes.  Eliminate doc/Makefile from tar.Z file if doc/Makefile.in
	exists.
	* mipsread.c:  Cleanup.  Add more complaints for unhandled cases.
	Remove new symbol types and such to ../include/coff/symconst.h.
	(parse_symbol):  Simplify code for parsing struct/enum/unions.
	(parse_type):  Handle `long long' types.
	(upgrade_type):  Handle `const' qualifier.
	(parse_partial_symbols):  fix indentation, clean a bit.

e10a30523e * Makefile.in (OBS): Compile mipsread.c for all targets now.
(VERSION):  Bump to 4.4.85.
* mipsread.c:  Update for new include files.  Lint.
* tm-irix3.h, tm-mips.h:  Use new include files for ECOFF symtab.
* config/{bigmips.mt, littlemips.mt, irix3.mt, decstation.mt}:
Don't need to bring in mipsread.o specially any more.

4ad1963ee0 * mipsread.c (fixup_sigtramp): Also look for _sigtramp as a real
routine (for Irix-4.x).  Make many funcs static and void.
* mips-tdep.c (mips-frame-chain):  Clean up, simplify.
* (init_extra_frame_info):  Don't trash cached value of frame
pointer register.  This fixes backtracing through routines that use
alloca().  Generally clean up declarations of functions, and use
typedefs and macros to reference data structures as appropriate.
* tm-irix3.h, tm-mips.h (EXTRA_FRAME_INFO):  use proper type for
proc_desc element.

Stu Grossman
d1bb1d4170 * 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.

dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove 2nd
unused copy!

5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
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.

	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

	* dbxread.c (dbx_new_init):  Move deallocation things to new
	dbx_symfile_finish function.
	* elfread.c (elf_new_init):  Call buildsym_new_init().

	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.

	for better support of mapped symbol tables.
	* symfile.c (symbol_file_command):  Remove obsolete code using

* 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.)

021959e249 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
* 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>.

only assuming union if multiple members have offsets of zero.

c55e616795 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.
(breakpoint_re_set_one):  Disable bkpts that don't re-set cleanly.
(breakpoint_re_set):  Mention breakpoint number in error messages.
* symtab.h (resolve_sal_pc):  Declare.

* source.c (find_source_lines):  Avoid "Source file is more
recent than executable" when bfd_get_mtime gives 0.
(list_command):  Shorten "FILE, line N" to "FILE:N".

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

        * mipsread.c (read_mips_symtab, read_the_mips_symtab,
        parse_partial_symbols): Use newer BFD internals (external_filehdr
        and external_aouthdr), byte-swap the fields that we care about
        before using them, and make the file header data local to
        read_the_mips_symtab rather than global.

d219db0133 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
defines for the blocks of a blockvector that contain global and
        file-static symbols and the first of the smaller scope contours.
	* mipsread.c:  Use them.

        * coffread.c (end_psymtab):  Free named symtabs and psymtabs for
        a file, once a new symtab has been read for it.
        * mipsread.c:  FIXME.  We need to do the same for MIPS, but it
        looks harder to determine the top-level block before it's been
        queued to the psymtab list.
