11549 (note_mem_written): Similarly for WRITE_PTR argument.
11550 (invalidate_from_clobbers): Similarly for W argument.
11551 (invalidate_for_call): Remove memory elements from the hash table.
11552 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
11553 (cse_rtx_varies_p): New function. Derived from old
11554 cse_rtx_addr_varies_p.
11555 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
11556 Don't call note_mem_written anymore. Stack pushes invalidate the stack
11557 pointer if PUSH_ROUNDING is defined. No longer need to call
11558 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
11559 (skipped_writes_memory): Remove variable.
11560 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
11561 (invalidate_skipped_block): Simplify for new alias analysis code.
11562 (cse_set_around_loop): Likewise.
11563 (cse_main): Call init_alias_analysis.
11564 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
11565 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
11566 (f_options): Add new alias checking arguments.
11567 (main): Set flag_alias_check when optimizing.
11568 * local_alloc (validate_equiv_mem_from_store): Add new arguments
11569 to true_dependence.
11570 (memref_referenced_p): Likewise.
11571 * loop.c (NUM_STORES): Increase to 30.
11572 (prescan_loop): Only non-constant calls set unknown_address_altered.
11573 (invariant_p): Add new arguments to true_dependence.
11574 (record_giv): Initialize unrolled and shared fields.
11575 (emit_iv_add_mult): Call record_base_value as needed.
11576 * loop.h (struct induction): Add unrolled and shared fields.
11577 * unroll.c (unroll_loop): Call record_base_value as needed.
11578 (copy_loop_body): Likewise.
11579 (final_biv_value): Likewise.
11580 (final_giv_value): Likewise.
11581 (find_splittable_regs): Likewise. Only create one new pseudo
11582 if we have multiple address GIVs that were combined with the same
11583 dst_reg GIV. Note when a new register is created due to unrolling.
11584 * rtl.c (reg_note_name): Add REG_NOALIAS.
11585 * rtl.h (enum reg_note): Similarly.
11586 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
11587 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
11588 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
11589 (true_dependence, read_dependence, anti_dependence): Likewise.
11590 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
11591 (mark_user_reg, mark_reg_pointer): Likewise.
11594 * Integrate reload bugfix from Wilon which enables the PA port
11595 to bootstrap again.
11596 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
11597 OPERAND_ADDRESS when computing how many registers an insn needs.
11598 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
11600 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
11601 OPADDR_ADDR reload.
11602 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
11603 in reload_reg_use_in_op_addr do not reach the end.
11604 do not reach the end.
11605 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
11606 RELOAD_FOR_OPERAND_ADDRESS.
