Annotate sparc objects with cpu hardware capabilities used.
bfd/ * elfxx-sparc.c (_bfd_sparc_elf_merge_private_bfd_data): New. * elfxx-sparc.h: Declare it. * elf32-sparc.c (elf32_sparc_merge_private_bfd_data): Call it. * elf64-sparc.c (elf64_sparc_merge_private_bfd_data): Likewise. binutils/ * readelf.c (display_sparc_hwcaps): New. (display_sparc_gnu_attribute): New. (process_sparc_specific): New. (process_arch_specific): When EM_SPARC, EM_SPARC32PLUS, or EM_SPARCV9 invoke process_sparc_specific. gas/ * config/tc-sparc.c (hwcap_seen): New bitmask, defined when not TE_SOLARIS. (sparc_ip): When not TE_SOLARIS, accumulate hwcap bits from sparc_opcode->flags of instruction into hwcap_seen. (sparc_md_end): Create Tag_GNU_Sparc_HWCAPS attribute if hwcap_seen is non-zero and not TE_SOLARIS. gas/testsuite/ * gas/sparc/hpcvis3.s: Update for fixed fchksum16 mnemonic. * gas/sparc/hpcvis3.d: Likewise. include/elf/ * sparc.h (Tag_GNU_Sparc_HWCAPS): New object attribute. (ELF_SPARC_HWCAP_*): New HWCAPS bitmask values. include/opcode/ * sparc.h (struct sparc_opcode): Expand 'flags' to unsigned int. (F_MUL32, F_DIV32, F_FSMULD, F_V8PLUS, F_POPC, F_VIS, F_VIS2, F_ASI_BLK_INIT, F_FMAF, F_VIS3, F_HPC, F_RANDOM, F_TRANS, F_FJFMAU, F_IMA, F_ASI_CACHE_SPARING): New flag bits. opcodes/ * sparc-opc.c (sparc_opcodes): Annotate table with HWCAP flag bits. Fix "fchksm16" mnemonic.
