From 5e7fc731f80e0d08385a05ad47dda332a49d9341 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Wed, 14 Dec 2016 21:49:56 +0000 Subject: MIPS/opcodes: Also set disassembler's ASE flags from ELF structures Respect any ASE flags recorded in ELF file structures for the purpose of selecting instructions to be disassembled, preventing code from being hex-dumped even though having been clearly indicated as valid at the assembly time. Use date from the MIPS ABI flags structure if present, and otherwise there may be an MDMX ASE flag set in the ELF file header. For backwards compatibility only set extra flags and do not clear any, preserving all previously set by the architecture selected to be disassembled for. include/ * elf/mips.h (Elf_Internal_ABIFlags_v0): Also declare struct typedef as `elf_internal_abiflags_v0'. bfd/ * bfd-in.h (elf_internal_abiflags_v0): New struct declaration. (bfd_mips_elf_get_abiflags): New prototype. * elfxx-mips.c (bfd_mips_elf_get_abiflags): New function. * bfd-in2.h: Regenerate. opcodes/ * mips-dis.c (mips_convert_abiflags_ases): New function. (set_default_mips_dis_options): Also infer ASE flags from ELF file structures. binutils/ * testsuite/binutils-all/mips/mips-ase-1.d: New test. * testsuite/binutils-all/mips/mips-ase-2.d: New test. * testsuite/binutils-all/mips/mips-ase-3.d: New test. * testsuite/binutils-all/mips/mips-ase-1.s: New test source. * testsuite/binutils-all/mips/mips-ase-2.s: New test source. * testsuite/binutils-all/mips/mips.exp: Run the new tests. --- bfd/elfxx-mips.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'bfd/elfxx-mips.c') diff --git a/bfd/elfxx-mips.c b/bfd/elfxx-mips.c index 96317aa..d649676 100644 --- a/bfd/elfxx-mips.c +++ b/bfd/elfxx-mips.c @@ -16327,6 +16327,16 @@ _bfd_mips_elf_get_synthetic_symtab (bfd *abfd, return n; } +/* Return the ABI flags associated with ABFD if available. */ + +Elf_Internal_ABIFlags_v0 * +bfd_mips_elf_get_abiflags (bfd *abfd) +{ + struct mips_elf_obj_tdata *tdata = mips_elf_tdata (abfd); + + return tdata->abiflags_valid ? &tdata->abiflags : NULL; +} + void _bfd_mips_post_process_headers (bfd *abfd, struct bfd_link_info *link_info) { -- cgit v1.1
