Add pointer to the objfile + into the struct sym_fns. + Replace global `symfile' and `symfile_mtime' with + `symfile_objfile'. Add global object_files chain. + + * symfile.c: Move param.h above symtab.h. + (sort_misc_function_vector): Add. + (syms_from_objfile): Was syms_from_bfd. + (symfile_open): Now returns objfile. + (allocate_objfile): New. + (free_objfile): New, replacing free_all_.*symtabs. + (symfile_init): Takes objfile arg, puts it in sym_fns result. + (reread_symbols): Searches whole chain of objfiles. + (allocate_symtab): Takes objfile as new parameter, chains them. + Handle INIT_EXTRA_SYMTAB_INFO. + (free_all_psymtabs, free_all_symtabs): Move here from symmisc.c. + + * dbxread.c: Make more errors into complaints. + (push_subfile, pop_subfile): Move to buildsym.c. + (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab, + start_psymtab, psymtab_to_symtab_1, read_ofile_symtab, + dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor. + Pass objfile. Change callers. + (fill_symbuf, SWAP_SYMBOL): Take bfd as arg. + (read_dbx_symtab): Just wipe out new symbols, not all, on error. + (end_psymtab): Blow away psymtab if empty. + (process_symbol_pair): Swallow into read_ofile_symtab. + (process_one_symbol): Use push_context and pop_context. + (virtual_context): Delete #if 0'd obsolete stuff. + + * buildsym.c (end_symtab): Pass objfile. + (dbx_lookup_type): Handle null typevector. + (dbx_alloc_type): Check file number, not sym number, for -1. + (find_symbol_in_list): Add for xcoffread. + (start_symtab): Default typevector is empty. Keep reusing same + context_stack. + (end_symtab): Take objfile argument and pass it to + allocate_symtab. Don't make a symtab if no blocks or symbols. + Handle empty typevector. + (push_context): New function for context stack nesting. + (read_type): Mark FIXME where we need to reintroduce type smashing. + + * buildsym.h (pop_context): Macro, paired with push_context. + (subfile_stack): Move here from dbxread.c. + + * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg. + (read_coff_symtab): Cleanup by freeing objfile, not all symtabs. + + * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr, + new_psymtab, new_symtab): Take and use objfile arg. + + * dwarfread.c (scan_compilation_units, start_psymtab, + process_dies, end_symtab, dwarf_build_psymtabs, + read_lexical_block_scope, read_func_scope, read_file_scope): Take + and use objfile argument. + (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file + descriptor. Use BFD internal functions instead. + (end_symtab): Call global allocate_symtab. + + * elfread.c: Minor changes to accommodate objfiles. + * symtab.h: partial_symbol_table has no symfile_name member now. + (fn_fieldlists voffset): avoid non-int bitfield. + (struct symtab): Add objfile * and objfile_chain * of symtabs. + (struct partial_symtab): Add objfile * and objfile_chain * of + psymtabs. Remove symfile_name. + + * symfile.h, symfile.c, symtab.h: Lint + Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com) * command.c: Include param.h. |
