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 <paul.hua.gm@gmail.com> Maciej W. Rozycki <macro@mips.com> 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.
