No. Alpha has certain builtin code which looks similar to calls or software interrupts but are executed in the CPU. This allows access to some memory in the CPU which is almost as fast as a normal register access. MIPS doesn't have such hardware. If you cannot find a register you're doomed. -- ---------------. ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Red Hat `--' drepper at redhat.com `------------------------
