--- Comment #1 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
In what way, exactly, do you think the output is incorrect?  Don't forget that
your testcase returns a uint16_t and the ABI says that it is the caller's
responsibility to do any widening, so any bits beyond bit 15 in the result
register are simply unspecified.

Secondly, you haven't stated which version of gcc you were using, or how it was
configured.
