From 8095d2f70e1a982c006f306be1a9e1c892758914 Mon Sep 17 00:00:00 2001 From: Chenghua Xu Date: Fri, 20 Jul 2018 13:21:33 +0100 Subject: MIPS/GAS: Split Loongson MMI Instructions from loongson2f/3a The MMI instruction set has been implemented in many Loongson processors. There is a lot of software optimized for MMI. This patch splits MMI from loongson2f/3a, and adds GAS and disassembler options for MMI instructions. 2018-07-20 Chenghua Xu Maciej W. Rozycki bfd/ * elfxx-mips.c (print_mips_ases): Add MMI extension. binutils/ * readelf.c (print_mips_ases): Add MMI extension. gas/ * NEWS: Mention MultiMedia extensions Instructions (MMI) support. * config/tc-mips.c (options): Add OPTION_LOONGSON_MMI and OPTION_NO_LOONGSON_MMI. (md_longopts): Likewise. (mips_ases): Define availability for MMI. (mips_convert_ase_flags): Map ASE_LOONGSON_MMI to AFL_ASE_LOONGSON_MMI. (mips_cpu_info_table): Add ASE_LOONGSON_MMI for loongson2f/3a. (md_show_usage): Add help for -mloongson-mmi and -mno-loongson-mmi. * doc/as.texi: Document -mloongson-mmi, -mno-loongson-mmi. * doc/c-mips.texi: Document -mloongson-mmi, -mno-loongson-mmi, .set loongson-mmi and .set noloongson-mmi. * testsuite/gas/mips/loongson-2f.d: Move mmi test to ... * testsuite/gas/mips/loongson-2f-mmi.d: Here.

(AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_MMI. * opcode/mips.h (ASE_LOONGSON_MMI): New macro. opcodes/ * mips-dis.c (mips_arch_choices): Add MMI to loongson2f and loongson3a descriptors. (parse_mips_ase_option): Handle -M loongson-mmi option. (print_mips_disassembler_options): Document -M loongson-mmi. * mips-opc.c (LMMI): New macro. (mips_opcodes): Replace IL2F|IL3A marking with LMMI for MMI instructions. --- gas/doc/as.texi | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'gas/doc/as.texi') diff --git a/gas/doc/as.texi b/gas/doc/as.texi index 49b1ef1..e9b6016 100644 --- a/gas/doc/as.texi +++ b/gas/doc/as.texi @@ -424,6 +424,7 @@ gcc(1), ld(1), and the Info entries for @file{binutils} and @file{ld}.
