8686 (true_dependence, read_dependence, anti_dependence): Likewise.
8687 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
8688 (mark_user_reg, mark_reg_pointer): Likewise.
8691 * Integrate reload bugfix from Wilon which enables the PA port
8693 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
8694 OPERAND_ADDRESS when computing how many registers an insn needs.
8695 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
8697 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
8699 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
8700 in reload_reg_use_in_op_addr do not reach the end.
8701 do not reach the end.
8702 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
8703 RELOAD_FOR_OPERAND_ADDRESS.
