2418 Don't call note_mem_written anymore. Stack pushes invalidate the stack
2419 pointer if PUSH_ROUNDING is defined. No longer need to call
2420 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
2421 (skipped_writes_memory): Remove variable.
2422 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
2423 (invalidate_skipped_block): Simplify for new alias analysis code.
2424 (cse_set_around_loop): Likewise.
2425 (cse_main): Call init_alias_analysis.
2426 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
2427 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
2428 (f_options): Add new alias checking arguments.
2429 (main): Set flag_alias_check when optimizing.
2430 * local_alloc (validate_equiv_mem_from_store): Add new arguments
2432 (memref_referenced_p): Likewise.
2433 * loop.c (NUM_STORES): Increase to 30.
2434 (prescan_loop): Only non-constant calls set unknown_address_altered.
2435 (invariant_p): Add new arguments to true_dependence.
2436 (record_giv): Initialize unrolled and shared fields.
2437 (emit_iv_add_mult): Call record_base_value as needed.
2438 * loop.h (struct induction): Add unrolled and shared fields.
2439 * unroll.c (unroll_loop): Call record_base_value as needed.
2440 (copy_loop_body): Likewise.
2441 (final_biv_value): Likewise.
2442 (final_giv_value): Likewise.
2443 (find_splittable_regs): Likewise. Only create one new pseudo
2444 if we have multiple address GIVs that were combined with the same
2445 dst_reg GIV. Note when a new register is created due to unrolling.
2446 * rtl.c (reg_note_name): Add REG_NOALIAS.
2447 * rtl.h (enum reg_note): Similarly.
2448 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
2449 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
2450 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
2451 (true_dependence, read_dependence, anti_dependence): Likewise.
2452 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
2453 (mark_user_reg, mark_reg_pointer): Likewise.
2456 * Integrate reload bugfix from Wilon which enables the PA port
2458 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
2459 OPERAND_ADDRESS when computing how many registers an insn needs.
2460 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
2462 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2464 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2465 in reload_reg_use_in_op_addr do not reach the end.
2466 do not reach the end.
2467 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2468 RELOAD_FOR_OPERAND_ADDRESS.
