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).
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.
(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.
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.
.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.
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.
elfread.c (coff_symfile_finish): Add function, prototype, and
add to the xxxx_sym_fns struct for each file type. Also reformat
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,
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().
* 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.)
* 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>.
* 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.
* infcmd.c (jump_command): Use resolve_sal_pc.
* 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.
filename with error messages.
* stack.c (frame_select_command): Rename to select_frame_command
to avoid "fr" and "fra" having nonunique completions.
* symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
(symfile_init): Print file format name when unable to handle it.
(free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
* symmisc.c (free_symtab): Only free linetable if nonzero.
* symtab.h: Remove obsolete BLOCKLIST macros.
(add_symbol_file): Call it to do the real work.
(syms_from_bfd): Initialize entry_point before calling symfile_init.
* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
of allocating and initializing a new struct symtab. Set the
language of the symtab based on its filename extension.
* symfile.h: Declare it.
* mipsread.c (new_symtab): Use it. Minor formatting changes.
* dbxread.c (end_symtab): Use it.
* mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
code for saving types of parameters with each function definition.
* dbxread.c (define_symbol, function and parameter cases): Ditto.
(read_dbx_symtab, case N_DEFD): Ignore.
(read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN
type.
(read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
#if 0 out its uses, though, since they set a dead value.
* coffread.c (end_symtab): Use allocate_symtab.
(process_coff_symbol): #if 0'd for functions and params as above.
(read_enum_type): Recognize Modula-2 BOOLEAN.
* mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
* 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.
* cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
* infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
(This still doesn't seem to make MIPS bkpts work.)
* mipsread.c: Remove dup "Reading symbol data..." msg.
(symbol_file_command, add_file_command): Remove, obsol.
* printcmd.c (ptype_command): Say "an enum" rather than "a enum".
Wrap output appropriately.

enums appropriately.
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.
