From 88fc725d2fa9234fef229e80472740610172421b Mon Sep 17 00:00:00 2001 From: Hans-Peter Nilsson Date: Sat, 18 Oct 2003 15:53:40 +0000 Subject: Generate BFD_RELOC_MMIX_PUSHJ_STUBBABLE for PUSHJ when possible. * doc/c-mmix.texi (MMIX-Opts): Document --no-pushj-stubs and --no-stubs. * config/tc-mmix.c: Include limits.h. Expand on mmix_relax_table comment. (expand_op, mmix_next_semicolon_is_eoln): Fix head comment. (pushj_stubs): New variable. (OPTION_NOPUSHJSTUBS, STATE_PUSHJSTUB, PUSHJSTUB_MIN) (PUSHJSTUB_MAX): New macros. (md_longopts): New options "--no-pushj-stubs" and synonym "--no-stubs". (mmix_relax_table): Handle new entry for STATE_PUSHJSTUB. (md_parse_option): Handle OPTION_NOPUSHJSTUBS. (md_estimate_size_before_relax): Modify STATE_PUSHJ state for PUSHJ stub relaxation. (md_convert_frag): Handle STATE_PUSHJSTUB. (md_apply_fix3): Handle BFD_RELOC_MMIX_PUSHJ_STUBBABLE. (tc_gen_reloc): Ditto. (mmix_md_relax_frag): Handle PUSHJ stub relaxation. * config/tc-mmix.h (TC_SEGMENT_INFO_TYPE): Define. (struct mmix_segment_info_type): New. --- gas/config/tc-mmix.h | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'gas/config/tc-mmix.h') diff --git a/gas/config/tc-mmix.h b/gas/config/tc-mmix.h index 30d2c952a66..c6d222f1fdd 100644 --- a/gas/config/tc-mmix.h +++ b/gas/config/tc-mmix.h @@ -1,5 +1,5 @@ /* tc-mmix.h -- Header file for tc-mmix.c. - Copyright (C) 2001, 2002 Free Software Foundation, Inc. + Copyright (C) 2001, 2002, 2003 Free Software Foundation, Inc.
