From bdc6c06e3b08ec48ec5ee2174dedc846969c36fd Mon Sep 17 00:00:00 2001 From: Chenghua Xu Date: Wed, 29 Aug 2018 19:57:39 +0800 Subject: [MIPS/GAS] Split Loongson EXT Instructions from loongson3a. bfd/ * elfxx-mips.c (infer_mips_abiflags): Use ases instead of isa_ext for infer ABI flags. (print_mips_ases): Add Loongson EXT extension. binutils/ * readelf.c (print_mips_ases): Add Loongson EXT extension. elfcpp/ * mips.h (AFL_ASE_LOONGSON_EXT): New enum. gas/ * NEWS: Mention Loongson EXTensions (EXT) support. * config/tc-mips.c (options): Add OPTION_LOONGSON_EXT and OPTION_NO_LOONGSON_EXT. (md_longopts): Likewise. (mips_ases): Define availability for EXT. (mips_convert_ase_flags): Map ASE_LOONGSON_EXT to AFL_ASE_LOONGSON_EXT. (mips_cpu_info_table): Add ASE_LOONGSON_EXT for loongson3a. (md_show_usage): Add help for -mloongson-ext and -mno-loongson-ext. * doc/as.texi: Document -mloongson-ext, -mno-loongson-ext. * doc/c-mips.texi: Document -mloongson-ext, -mno-loongson-ext, .set loongson-ext and .set noloongson-ext. * testsuite/gas/mips/loongson-mmi.d: Add ASE flag. include/ * elf/mips.h (AFL_ASE_LOONGSON_EXT): New macro. (AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_EXT. * opcode/mips.h (ASE_LOONGSON_EXT): New macro. opcodes/ * mips-dis.c (mips_arch_choices): Add EXT to loongson3a descriptors. (parse_mips_ase_option): Handle -M loongson-ext option. (print_mips_disassembler_options): Document -M loongson-ext. * mips-opc.c (IL3A): Delete. * mips-opc.c (LEXT): New macro. (mips_opcodes): Replace IL2F|IL3A marking with LEXT for EXT instructions. --- include/ChangeLog | 6 ++++++ include/elf/mips.h | 3 ++- include/opcode/mips.h | 2 ++ 3 files changed, 10 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/ChangeLog b/include/ChangeLog index 27f0202..b45a328 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,5 +1,11 @@ 2018-08-29 Chenghua Xu + * elf/mips.h (AFL_ASE_LOONGSON_EXT): New macro. + (AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_EXT. + * opcode/mips.h (ASE_LOONGSON_EXT): New macro. + +2018-08-29 Chenghua Xu + * elf/mips.h (AFL_ASE_LOONGSON_CAM): New macro.
