Hello, Here is the latest patch with the change: -mmt/-mno-mt. Also, "mips32-mt.d" is changed to use "-mmt". I built and tested for mipsisa32-elf and mipsisa64-elf. No new regression. Any comments? Thanks!

Document !, $, *, &, g, +t, +T operand formats for MT instructions. (INSN_ASE_MASK): Update to include INSN_MT. (INSN_MT): New define for MT ASE. opcodes/ChangeLog 2005-08-30 Chao-ying Fu * mips-opc.c (MT32): New define. (mips_builtin_opcodes): Move "bc0f", "bc0fl", "bc0t", "bc0tl" to the bottom to avoid opcode collision with "mftr" and "mttr". Add MT instructions. * mips-dis.c (mips_arch_choices): Enable INSN_MT for mips32r2. (print_insn_args): Add supports for +t, +T, !, $, *, &, g operand formats. gas/ChangeLog 2005-08-30 Chao-ying Fu * 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. gas/testsuite/ChangeLog 2005-08-30 Chao-ying Fu * gas/mips/mips.exp: Run MT test for mips32r2 only. * gas/mips/mips32-mt.[sdl]: New test. ----- Original Message ----- From: "Eric Christopher" To: "Daniel Jacobowitz" Cc: "Chao-ying Fu" ; "Thiemo Seufer" ; "Maciej W.
