(fwprop_init): Always call loop_optimizer_initialize. (fwprop_done): Always call loop_optimizer_finalize. (fwprop): We always have loop info now. (gate_fwprop_addr): Remove. (pass_fwprop_addr): Use gate_fwprop as gate. PR rtl-optimization/30841 * df-problems.c (df_ru_local_compute, df_rd_local_compute, df_chain_alloc): Call df_reorganize_refs unconditionally. * df-scan.c (df_rescan_blocks, df_reorganize_refs): Change refs_organized to refs_organized_size. (df_ref_create_structure): Use refs_organized_size instead of bitmap_size if refs had been organized, and keep refs_organized_size up-to-date. * df.h (struct df_ref_info): Change refs_organized to refs_organized_size. (DF_DEFS_SIZE, DF_USES_SIZE): Use refs_organized_size instead of bitmap_size.
