10597 * local_alloc (validate_equiv_mem_from_store): Add new arguments
10598 to true_dependence.
10599 (memref_referenced_p): Likewise.
10600 * loop.c (NUM_STORES): Increase to 30.
10601 (prescan_loop): Only non-constant calls set unknown_address_altered.
10602 (invariant_p): Add new arguments to true_dependence.
10603 (record_giv): Initialize unrolled and shared fields.
10604 (emit_iv_add_mult): Call record_base_value as needed.
10605 * loop.h (struct induction): Add unrolled and shared fields.
10606 * unroll.c (unroll_loop): Call record_base_value as needed.
10607 (copy_loop_body): Likewise.
10608 (final_biv_value): Likewise.
10609 (final_giv_value): Likewise.
10610 (find_splittable_regs): Likewise. Only create one new pseudo
10611 if we have multiple address GIVs that were combined with the same
10612 dst_reg GIV. Note when a new register is created due to unrolling.
10613 * rtl.c (reg_note_name): Add REG_NOALIAS.
10614 * rtl.h (enum reg_note): Similarly.
10615 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
10616 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
10617 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
10618 (true_dependence, read_dependence, anti_dependence): Likewise.
10619 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
10620 (mark_user_reg, mark_reg_pointer): Likewise.
10623 * Integrate reload bugfix from Wilon which enables the PA port
10624 to bootstrap again.
10625 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
10626 OPERAND_ADDRESS when computing how many registers an insn needs.
10627 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
10629 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
10630 OPADDR_ADDR reload.
10631 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
10632 in reload_reg_use_in_op_addr do not reach the end.
10633 do not reach the end.
10634 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
10635 RELOAD_FOR_OPERAND_ADDRESS.
