Annotate sparc objects with cpu hardware capabilities used.

Browse Source 
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.
