re PR middle-end/30907 (Propagation of addresses within loops pessimizes code)
2007-03-19 Paolo Bonzini <bonzini@gnu.org>
PR rtl-optimization/30907
* fwprop.c (forward_propagate_into): Never propagate inside a loop.
(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.
