So as opposed to a unary operation which would look exactly the same apart
from having a subcode? So what does gimple_assign_subcode () return
for the GIMPLE_SINGLE_RHS case? Some random garbage?
Seems I need to look at the tuples branch closer. Is there some overview
documentation available that explains all the above?
