3909
        (note_mem_written): Similarly for WRITE_PTR argument.
3910
        (invalidate_from_clobbers): Similarly for W argument.
3911
        (invalidate_for_call): Remove memory elements from the hash table.

3915
        (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
3916
        Don't call note_mem_written anymore.  Stack pushes invalidate the stack
3917
        pointer if PUSH_ROUNDING is defined.  No longer need to call
3918
        cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
3919
        (skipped_writes_memory): Remove variable.
3920
        (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
3921
        (invalidate_skipped_block): Simplify for new alias analysis code.
3922

3933
        (invariant_p): Add new arguments to true_dependence.
3934
        (record_giv): Initialize unrolled and shared fields.
3935
        (emit_iv_add_mult): Call record_base_value as needed.
3936
        * loop.h (struct induction): Add unrolled and shared fields.
3937
        * unroll.c  (unroll_loop): Call record_base_value as needed.
3938
        (copy_loop_body): Likewise.

3940
        (final_giv_value): Likewise.
3941
        (find_splittable_regs): Likewise.  Only create one new pseudo
3942
        if we have multiple address GIVs that were combined with the same
3943
        dst_reg GIV.  Note when a new register is created due to unrolling.
3944
        * rtl.c (reg_note_name): Add REG_NOALIAS.
3945
        * rtl.h (enum reg_note): Similarly.
3946
        (rtx_varies_p, may_trap_p, side_effects_p): Declare.
3947
        (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
3948
        (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
3949
        (true_dependence, read_dependence, anti_dependence): Likewise.
3950
        (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
3951
        (mark_user_reg, mark_reg_pointer): Likewise.

        * Integrate reload bugfix from Wilon which enables the PA port
3954
        to bootstrap again.
3955
        * reload1.c (reload): Sum needs for both OPADDR_ADDR and
3956
        OPERAND_ADDRESS when computing how many registers an insn needs.
3957
        (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
3958
        conflict.
3959
        (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3960
        OPADDR_ADDR reload.
3961
        (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3962
        in reload_reg_use_in_op_addr do not reach the end.
3963
        do not reach the end.
3964
        (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
3965
        RELOAD_FOR_OPERAND_ADDRESS.
