Add support for sparc fused compare-and-branch.
gcc/ 2012-11-15 David S. Miller <davem@davemloft.net> * configure.ac: Add check for assembler SPARC4 instruction support. * configure: Rebuild. * config.in: Add HAVE_AS_SPARC4 section. * config/sparc/sparc.opt (mcbcond): New option. * doc/invoke.texi: Document it. * config/sparc/constraints.md: New constraint 'A' for 5-bit signed immediates. * doc/md.texi: Document it. * config/sparc/sparc.c (dump_target_flag_bits): Handle MASK_CBCOND. (sparc_option_override): Likewise. (emit_cbcond_insn): New function. (emit_conditional_branch_insn): Call it. (emit_cbcond_nop): New function. (output_ubranch): Use cbcond, remove label arg. (output_cbcond): New function. * config/sparc/sparc-protos.h (output_ubranch): Update. (output_cbcond): Declare it. (emit_cbcond_nop): Likewise. * config/sparc/sparc.md (type attribute): New types 'cbcond' and uncond_cbcond. (emit_cbcond_nop): New attribute. (length attribute): Handle cbcond and uncond_cbcond. (in_call_delay attribute): Reject cbcond and uncond_cbcond. (in_branch_delay attribute): Likewise. (in_uncond_branch_delay attribute): Likewise. (in_annul_branch_delay attribute): Likewise. (*cbcond_sp32, *cbcond_sp64): New insn patterns. (jump): Rewrite into an expander. (*jump_ubranch, *jump_cbcond): New patterns. * config/sparc/niagara4.md: Match 'cbcond' in 'n4_cti'. * config/sparc/sparc.h (AS_NIAGARA4_FLAG): New macro, use it when target default is niagara4. (SPARC_SIMM5_P): Define. * config/sparc/sol2.h (AS_SPARC64_FLAG): Adjust. (AS_SPARC32_FLAG): Define. (ASM_CPU32_DEFAULT_SPEC, ASM_CPU64_DEFAULT_SPEC): Use AS_NIAGARA4_FLAG as needed.
