  Ok, thats what I wanted to know. So, if I assign the temporary explict

  the expressions become well-formed and don't violate other constraints,
  right?

If you are asking whether
  ({int i; int j __asm__("d0"); volatile asm ("..." : "=r"(j)...); i = j; i;})
will DTRT, the answer is no.

If you are asking something else, you'll have to rephrase it.
