(verify_flow_info): Wrap with macro ENABLE_CHECKING. (mark_set_1): Initialize variable `regno'. (unlink_insn_chain): Likewise for variable `curr'. (remove_fake_edges): Remove unused variables `e', `tmp' and `last'. * loop.c (strength_reduce): Initialize variable `unrolled_insn_copies'. (cmp_combine_givs_stats, cmp_recombine_givs_stats): Add static prototypes. Change these functions to take const PTR parameters to avoid prototype conflict when used as the comparson argument for qsort. (check_dbra_loop): Initialize variable `comparison_val'. * reload.c (debug_reload_to_stream, debug_reload): Add prototypes. (get_secondary_mem): Mark parameter `x' with ATTRIBUTE_UNUSED. (find_valid_class): Initialize variable `best_class'. (find_reloads): Call memcpy, not bcopy. * reload1.c (gen_mode_int, dump_needs): Add prototypes. (hard_reg_use_compare): Don't needlessly cast away const. (reload_reg_class_lower): Likewise. (choose_reload_regs): Initialize variable `regno'. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@29840 138bc75d-0d04-0410-961f-82ee72b054a4
