sparc.c (gen_compare_reg): Kill 2nd and 3rd argument, they are always sparc_compare_op0 and sparc_compare_op1.
* config/sparc/sparc.c (gen_compare_reg): Kill 2nd and 3rd
argument, they are always sparc_compare_op0 and sparc_compare_op1.
(gen_v9_scc): Update callers.
* config/sparc/sparc.md: Likewise.
* config/sparc/sparc-protos.h: Update extern declaration.
