* flow.c (loop_depth): Remove. (reg_next_use, cc0_live, mem_set_list): Replace with ... (struct propagate_block_info): New. (life_analysis): Don't allocate reg_next_use. (propagate_block_delete_insn): Break out of propagate_block. Use flow_delete_insn to unlink rather than use NOTE_INSN_DELETED. (propagate_block_delete_libcall): Likewise. (propagate_block): Create a propagate_block_info struct to pass to subroutines. Allocate one not two temporary regsets. Don't clobber memory for const calls. Look for clobbers in CALL_INSN_FUNCTION_USAGE. (mark_set_regs): Recognize COND_EXEC. (mark_set_reg): Break out of mark_set_1. (mark_used_reg): Break out of mark_used_regs. (mark_used_regs): Recognize COND_EXEC. (insn_dead_p): Use propagate_block_info struct. (libcall_dead_p, invalidate_mems_from_autoinc): Likewise. (find_auto_inc, try_pre_increment_1): Likewise. (print_rtl_with_bb): Dump regs live at end too. (count_reg_sets_1): Pass in loop_depth. (count_reg_sets, count_reg_references): Likewise. (recompute_reg_usage): Provide it. From-SVN: r33012 |
