--- Comment #14 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- We don't normally split double-word operations because the thumb1 port cannot expose the Carry flag (most operations clobber the PSR, so it unsafe to do so until after register allocation; we have very limited support for post-regalloc as well). I think this confirms that we will need a separate test for thumb1 and a separate ticket to see if code can be further improved there.
