(check_mem_read_rtx): Added parameter to replace_read. (dse_step1): Added regs_live bitmap and initialize it. (rest_of_handle_dse): Added DF_NOTES problem and earlier call to df_analyze. * df-problems.c Renamed to df_simulate_initialize_backwards. (df_simulate_one_insn): Renamed to df_simulate_one_insn_backwards. (df_simulate_artificial_refs_at_top): Renamed to df_simulate_finalize_backwards.
