3430 | * Integrate reload bugfix from Wilon which enables the PA port | |
5fa39bfe JL |
3431 | to bootstrap again. |
3432 | * reload1.c (reload): Sum needs for both OPADDR_ADDR and and | |
3433 | OPERAND_ADDRESS when computing how many registers an insn needs. | |
3434 | (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do | |
3435 | conflict. | |
3436 | (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like | |
3437 | OPADDR_ADDR reload. | |
3438 | (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers | |
3439 | in reload_reg_use_in_op_addr do not reach the end. | |
3440 | do not reach the end. | |
3441 | (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with | |
3442 | RELOAD_FOR_OPERAND_ADDRESS. | |
