4800 pointer, mark it as such.
4801 * combine.c (distribute_notes): Handle REG_NOALIAS.
4802 * cse.c (struct write_data): Delete. No longer needed.
4803 (invalidate): Don't call set_nonvarying_address_components anymore.
4804 Use true_dependence to decide if an entry should be removed from
4806 (invalidate_memory): Remove WRITES argument, simplify appropriately.
4808 (note_mem_written): Similarly for WRITE_PTR argument.
4809 (invalidate_from_clobbers): Similarly for W argument.
4810 (invalidate_for_call): Remove memory elements from the hash table.
4811 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
4812 (cse_rtx_varies_p): New function. Derived from old
4813 cse_rtx_addr_varies_p.
4814 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
4815 Don't call note_mem_written anymore. Stack pushes invalidate the stack
4816 pointer if PUSH_ROUNDING is defined. No longer need to call
4817 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
4818 (skipped_writes_memory): Remove variable.
4819 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
4820 (invalidate_skipped_block): Simplify for new alias analysis code.
4821 (cse_set_around_loop): Likewise.
4822 (cse_main): Call init_alias_analysis.
4823 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
4824 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
4825 (f_options): Add new alias checking arguments.
4826 (main): Set flag_alias_check when optimizing.
4827 * local_alloc (validate_equiv_mem_from_store): Add new arguments
4829 (memref_referenced_p): Likewise.
4830 * loop.c (NUM_STORES): Increase to 30.
4831 (prescan_loop): Only non-constant calls set unknown_address_altered.
4832 (invariant_p): Add new arguments to true_dependence.
4833 (record_giv): Initialize unrolled and shared fields.
4834 (emit_iv_add_mult): Call record_base_value as needed.
4835 * loop.h (struct induction): Add unrolled and shared fields.
4836 * unroll.c (unroll_loop): Call record_base_value as needed.
4837 (copy_loop_body): Likewise.
4838 (final_biv_value): Likewise.
4839 (final_giv_value): Likewise.
4840 (find_splittable_regs): Likewise. Only create one new pseudo
4841 if we have multiple address GIVs that were combined with the same
4842 dst_reg GIV. Note when a new register is created due to unrolling.
4843 * rtl.c (reg_note_name): Add REG_NOALIAS.
4844 * rtl.h (enum reg_note): Similarly.
4845 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
4846 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
4847 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
4848 (true_dependence, read_dependence, anti_dependence): Likewise.
4849 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
4850 (mark_user_reg, mark_reg_pointer): Likewise.
4853 * Integrate reload bugfix from Wilon which enables the PA port
4855 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
4856 OPERAND_ADDRESS when computing how many registers an insn needs.
4857 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
4859 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
4861 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
4862 in reload_reg_use_in_op_addr do not reach the end.
4863 do not reach the end.
4864 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
4865 RELOAD_FOR_OPERAND_ADDRESS.
