961 chains and hard regs. Don't terminate chains when we find a read we
962 can't handle, mark it unrenameable instead. For terminate_write,
963 terminate chains that are written with an exact match or a superset
964 of registers. Set fail_current_block if multi-word lifetimes are too
966 (scan_rtx_address): Use mark_all_read instead of terminate_all_read.
967 (build_def_use): Initialize current_id, live_chains and live_hard_regs;
968 free memory for them when done.
969 Rearrange the steps so that earlyclobbers are noted before reads
970 are processed. Add new steps to keep track of hard register lifetimes
971 outside insn operands.
