At -O1, the simplified test-case exposes the bug for cris-elf too.
FWIW, I guess you must compile with *at most* -O1.

(With -O0 and -O2, the code compiles for cris-elf; with -O2 to an empty
function which seems correct, but with -O0 to something...that's probably
correct too, just can't follow it easily enough to be sure without executing
it. :)
