Add TODO list to make this pass faster/cleaner/better. (struct ls_expr): Post gcse.c-split cleanups. Rename to st_expr. Rename "loads" field to "antic_stores". Rename "stores" field to "avail_stores". (pre_ldst_mems): Rename to store_motion_mems. (pre_ldst_table): Rename to store_motion_mems_table. (pre_ldst_expr_hash): Rename to pre_st_expr_hash, update users. (pre_ldst_expr_eq): Rename to pre_st_expr_eq, update users. (ldst_entry): Rename to st_expr_entry, update users. (free_ldst_entry): Rename to free_st_expr_entry, update users. (free_ldst_mems): Rename to free_store_motion_mems, update users. (enumerate_ldsts): Rename to enumerate_store_motion_mems, update caller. (first_ls_expr): Rename to first_st_expr, update users. (next_ls_expr): Rename to next_st_expr, update users. (print_ldst_list): Rename to print_store_motion_mems. Print names of fields properly for store motion instead of names inherited from load motion in gcse.c. (ANTIC_STORE_LIST, AVAIL_STORE_LIST): Remove. (LAST_AVAIL_CHECK_FAILURE): Explain what this is. Undefine when we are done with it. (ae_kill): Rename to st_kill, update users. (ae_gen): Rename to st_avloc, update users. (transp): Rename to st_transp, update users. (pre_insert_map): Rename to st_insert_map, update users. (pre_delete_map): Rename to st_delete_map, update users. (insert_store, build_store_vectors, free_store_memory, one_store_motion_pass): Update for abovementioned changes. (gcse_subst_count, gcse_create_count): Remove. (one_store_motion_pass): New statistics counters "n_stores_deleted" and "n_stores_created", local variables. (extract_mentioned_regs, extract_mentioned_regs_1): Rewrite to use for_each_rtx. (regvec, compute_store_table_current_insn): Remove. (reg_set_info, reg_clear_last_set): Remove. (compute_store_table): Use DF caches instead of local dataflow solvers. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@147034 138bc75d-0d04-0410-961f-82ee72b054a4
* * gcse.c (ae_gen): Remove.steven2009-04-301-0/+1405
(can_assign_to_reg_p): Rename to can_assign_to_reg_without_clobbers_p and make non-static function to make it available in store-motion.c. Update call sites with search-and-replace.

Also copy data structures from gcse.c and clean up to remove parts not used by store motion. * rtl.h (can_assign_to_reg_without_clobbers_p): Add prototype. * Makefile.in (store-motion.o): New rule. Add to OBJS-common. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@147001 138bc75d-0d04-0410-961f-82ee72b054a4
