+ * sched-deps.c (reg_pending_uses_head): New.
+ (reg_pending_barrier): Rename from reg_pending_sets_all.
+ (find_insn_list): Don't mark inline.
+ (find_insn_mem_list): Remove.
+ (add_dependence_list, add_dependence_list_and_free): New.
+ (flush_pending_lists): Replace only_write param with separate
+ for_read and for_write parameters. Update all callers. Use
+ add_dependence_list_and_free.
+ (sched_analyze_1): Do not add reg dependencies here; just set
+ the pending bits. Use add_dependence_list.
+ (sched_analyze_2): Likewise.
+ (sched_analyze_insn): Replace schedule_barrier_found with
+ reg_pending_barrier. Add all dependencies for pending reg
+ uses, sets, and clobbers.
+ (sched_analyze): Don't add reg dependencies for calls, just
+ set pending bits. Use regs_invalidated_by_call. Treat
+ sched_before_next_call as a normal list, not a fake insn.
+ (init_deps): No funny init for sched_before_next_call.
+ (free_deps): Free pending mems lists. Don't zero reg_last.
+ (init_deps_global): Init reg_pending_uses.
+ (finish_deps_global): Free it.
+ * sched-int.h (deps): Make in_post_call_group_p boolean. Update docs.
+ (find_insn_mem_list): Remove.
+ * sched-rgn.c (concat_INSN_LIST, concat_insn_mem_list): New.
+ (propagate_deps): Use them. Zero temp mem lists.
