+ * cprop.c (struct expr): Split 'expr' field in 'dest' and 'src'.
+ (expr_equiv_p): Remove.
+ (insert_set_in_table): Look at <dest, src> pair instead of expr.
+ (hash_scan_set): Update call to insert_set_in_table.
+ (dump_hash_table): Dump <dest, src> pair.
+ (lookup_set): Simplify. Lookup <dest, src> pair.
+ (compute_transp): Remove, fold heavily simplified code into...
+ (compute_local_properties): ...here. Expect COMP and TRANSP
+ unconditionally.
+ (find_avail_set): Take set directly from struct expr.
+ (find_bypass-set): Likewise.
+ (bypass_block): Likewise.
+ (cprop_insn): Likewise. Remove redundant INSN_P test.
+
+ * cprop.c (implicit_set_cond_p): Assume nothing about COND, move
+ checks on form of COND from find_implicit_sets to here.
+ (find_implicit_sets): Cleanup control flow. Split critical edges
+ if it exposes implicit sets. Allocate/resize implicit_sets as
+ necessary.
+ (one_cprop_pass): Only delete unreachable blocks if local_cprop_pass
+ changed something. Run df_analyze after find_implicit_sets if any
+ edges were split. Do not allocate implicit_sets here.
+
+ * cprop.c: s/gcse/cprop/ everywhere except for flag_gcse.
+ (gcse_obstack): Renamed to cprop_obstack.
+ (GNEW, GNEWVEC, GNEWVAR): Remove.
+ (gmalloc): Remove.
+ (alloc_hash_table): Use XNEWVAR instead of GNEWVAR.
+ (GOBNEW, GOBNEWVAR): Adjust for gcse_obstack renaming.
+ (gcse_alloc): Likewise, and rename to cprop_alloc.
+ (alloc_gcse_men, free_gcse_mem): Remove.
+ (gcse_constant_p): Rename to cprop_constant_p, and adjust all callers.
+ (compute_hash_table_work): Allocate and free reg_set_bitmap here.
+ (one_cprop_pass): Likewise. Adjust for gcse_obstack renaming.
+
+ * cprop.c (oprs_not_set_p): Remove.
+ (mark_set, mark_clobber): Remove.
+ (mark_oprs_set): Rewrite using DF_INSN_INFO_DEFS cache.
+ (reg_not_set_p): New function.
+ (find_avail_set): Use reg_not_set_p instead of oprs_not_set_p.
+ (cprop_insn): Likewise.
+ (cprop_jump): Use FOR_EACH_EDGE.

+ * haifa-sched.c (nonscheduled_insns_begin): New static variable.
+ (rank_for_schedule): Use scheduled_insns vector instead of
+ last_scheduled_insn.
+ (ok_for_early_queue_removal): Likewise.
+ (queue_to_ready): Search forward in nonscheduled_insns_begin if
+ we have a dbg_cnt.
+ (choose_ready): Likewise.
+ (commit_schedule): Use VEC_iterate.
+ (schedule_block): Initialize nonscheduled_insns_begin. If we have
+ a dbg_cnt, use it and ensure the first insn is in the ready list.
+ (haifa_sched_init): Allocate scheduled_insns.
+ (sched_extend_ready_list): Don't allocate it; reserve space.
+ (haifa_sched_finish): Free it.
