2424 (invalidate_from_clobbers): Similarly for W argument.
2425 (invalidate_for_call): Remove memory elements from the hash table.
2426 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
2427 (cse_rtx_varies_p): New function. Derived from old
2428 cse_rtx_addr_varies_p.
2429 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
2430 Don't call note_mem_written anymore. Stack pushes invalidate the stack
2431 pointer if PUSH_ROUNDING is defined. No longer need to call
2432 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
2433 (skipped_writes_memory): Remove variable.
2434 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
2435 (invalidate_skipped_block): Simplify for new alias analysis code.
2436 (cse_set_around_loop): Likewise.
2437 (cse_main): Call init_alias_analysis.
2438 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
2439 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
2440 (f_options): Add new alias checking arguments.
2441 (main): Set flag_alias_check when optimizing.
2442 * local_alloc (validate_equiv_mem_from_store): Add new arguments
2444 (memref_referenced_p): Likewise.
2445 * loop.c (NUM_STORES): Increase to 30.
2446 (prescan_loop): Only non-constant calls set unknown_address_altered.
2447 (invariant_p): Add new arguments to true_dependence.
2448 (record_giv): Initialize unrolled and shared fields.
2449 (emit_iv_add_mult): Call record_base_value as needed.
2450 * loop.h (struct induction): Add unrolled and shared fields.
2451 * unroll.c (unroll_loop): Call record_base_value as needed.
2452 (copy_loop_body): Likewise.
2453 (final_biv_value): Likewise.
2454 (final_giv_value): Likewise.
2455 (find_splittable_regs): Likewise. Only create one new pseudo
2456 if we have multiple address GIVs that were combined with the same
2457 dst_reg GIV. Note when a new register is created due to unrolling.
2458 * rtl.c (reg_note_name): Add REG_NOALIAS.
2459 * rtl.h (enum reg_note): Similarly.
2460 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
2461 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
2462 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
2463 (true_dependence, read_dependence, anti_dependence): Likewise.
2464 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
2465 (mark_user_reg, mark_reg_pointer): Likewise.
2468 * Integrate reload bugfix from Wilon which enables the PA port
2470 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
2471 OPERAND_ADDRESS when computing how many registers an insn needs.
2472 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
2474 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2476 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2477 in reload_reg_use_in_op_addr do not reach the end.
2478 do not reach the end.
2479 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2480 RELOAD_FOR_OPERAND_ADDRESS.
