From ef2e4d86d6823ab027adcbe57ba3ffaf38a550c2 Mon Sep 17 00:00:00 2001 From: Chao-ying Fu Date: Tue, 6 Sep 2005 18:53:03 +0000 Subject: * config/tc-mips.c (mips_set_options): Add ase_mt for MT instructions. (mips_opts): Add -1 to initialize ase_mt. (file_ase_mt): New variable for -mmt. (CPU_HAS_MT): New define. (validate_mips_insn): Add supports for +t, +T, !, $, *, &, g operand formats. (mips_ip): Check ase_mt to enable MT instructions. Handle !, $, *, &, +T, +t, g operand formats. For "mftc1", "mfthc1", "cftc1", "mttc1", "mtthc1", "cttc1", we allow odd float registers. (OPTION_MT, OPTION_NO_MT): New define. (OPTION_COMPAT_ARCH_BASE): Change because of inserting MT define. (md_parse_option): Parse OPTION_MT and OPTION_NO_MT. (mips_after_parse_args): Set ase_mt based on CPU. (s_mipsset): Handle ".set mt" and ".set nomt". (mips_elf_final_processing): Remind of adding new flag for MT ASE. (md_show_usage): Show usage of -mmt and -mno-mt. * doc/as.texinfo: Document -mmt and -mno-mt options. * doc/c-mips.texi: Likewise, and document ".set mt" and ".set nomt" directives. --- gas/doc/c-mips.texi | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'gas/doc/c-mips.texi') diff --git a/gas/doc/c-mips.texi b/gas/doc/c-mips.texi index 97469fe244..40be0fb163 100644 --- a/gas/doc/c-mips.texi +++ b/gas/doc/c-mips.texi @@ -118,6 +118,12 @@ Generate code for the MDMX Application Specific Extension.
