4310 * Integrate reload bugfix from Wilon which enables the PA port
4312 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
4313 OPERAND_ADDRESS when computing how many registers an insn needs.
4314 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
4316 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
4318 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
4319 in reload_reg_use_in_op_addr do not reach the end.
4320 do not reach the end.
4321 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
4322 RELOAD_FOR_OPERAND_ADDRESS.
