(symbol_begin): Initialize local_hash. (print_symbol_value_1): Handle local symbols. (symbol_print_statistics): Print local symbol statistics. * symbols.h: Include "struc-symbol.h" if not BFD_ASSEMBLER. Declare new symbols.c functions. Move many declarations here from struc-symbol.h. (SYMBOLS_NEED_BACKPOINTERS): Define if needed. * struc-symbol.h (SYMBOLS_NEED_BACKPOINTERS): Don't set. (struct symbol): Move bsym to make it clearly the first field. Remove TARGET_SYMBOL_FIELDS. (symbolS): Don't typedef. (struct broken_word): Remove. (N_TYPE_seg, seg_N_TYPE): Move to symbol.h. (SEGMENT_TO_SYMBOL_TYPE, N_REGISTER): Likewise. (symbol_clear_list_pointers): Likewise.

Define. * write.c (write_object_file): Call resolve_local_symbol_values. * config/obj-ecoff.h (OBJ_SYMFIELD_TYPE): Define. (TARGET_SYMBOL_FIELDS): Don't define. * config/obj-elf.h (OBJ_SYMFIELD_TYPE): Add local field. If ECOFF_DEBUGGING, add ECOFF fields. (ELF_TARGET_SYMBOL_FIELDS, TARGET_SYMBOL_FIELDS): Don't define. * config/obj-multi.h (struct elf_obj_sy): Add local field. If ECOFF_DEBUGGING, add ECOFF fields.

(TARGET_SYMBOL_FIELDS): Don't define. (struct mcore_tc_sy): Define. (TC_SYMFIELD_TYPE): Define. * Many files: Use symbolS instead of struct symbol. Use new accessor functions rather than referring to symbolS fields directly. * read.c (s_mri_common): Don't add in value of line_label. * config/tc-mips.c (md_apply_fix): Correct parenthesization when checking for SEC_LINK_ONCE. * config/tc-sh.h (sh_fix_adjustable): Declare. --- gas/ecoff.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'gas/ecoff.h') diff --git a/gas/ecoff.h b/gas/ecoff.h index 1a9b6fc..8ac65f8 100644 --- a/gas/ecoff.h +++ b/gas/ecoff.h @@ -1,5 +1,5 @@ /* ecoff.h -- header file for ECOFF debugging support - Copyright (C) 1993, 94, 95, 96, 1997 Free Software Foundation, Inc. + Copyright (C) 1993, 94, 95, 96, 97, 98, 1999 Free Software Foundation, Inc.
