you then have to fuss whether the evaluation of a has side-effects, and if so, add an assignment to a temporary. it turns out that the existing code needs only a little more care about which type is used to allocate registers, and on the RISCy machines it will then work. 8c is a little more involved because of the 387's architecture. there probably won't be much code, but it's fiddly. it would be nice finally to switch to SSE but i suppose there might still be some SSE-less x86/32 processors.
