(*zero_extend<mode>si2_compact): Convert to insn_and_split. Convert zero extensions of T bit stores to reg moves in splitter. Remove obsolete unnamed peephole2 that caught zero extensions after negc T bit stores. (*branch_true_eq, *branch_false_ne): Delete. (branch_true, branch_false): Convert insn to expander. Move actual insn logic to... (*cbranch_t): ...this new insn_and_split. Try to find preceding redundant T bit stores and tests and combine them with the conditional branch if possible in the splitter. (movrt_xor, *movt_movrt): New insn_and_split. * config/sh/predicates.md (cbranch_treg_value): New predicate. * config/sh/sh-protos.h (sh_eval_treg_value): Forward declare... * config/sh/sh.c (sh_eval_treg_value): ...this new function. (expand_cbranchsi4, expand_cbranchdi4): Remove get_t_reg_rtx when invoking gen_branch_true or gen_branch_false.
