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.
bout.c (b_out_squirt_out_relocs): treat abs sumbols the right way.
* reloc.c (bfd_perform-relocation): don't relocate refs to
absolute symbols if doing a partial link.
structure before initializing the fields that are used, so that the unused
fields are in a known state. Two of these structures are memcmp'd so
any fields not explicitly initialized must be set to a known state.
