--- Comment #4 from Nicholas Piggin <npiggin at gmail dot com> ---
I would like to reopen this. The example provided is not the desired operation,
it was just an example.

Such register-pair instructions in Power are not usable in extended inline asm
without this (except maybe by explicit fixed allocation with clobbers or
register variables which is undesirable).
