--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> ---
Confirmed. I see what the problem is. When we expand the built-in, the cast
to the proper type is lost and we only see a char *vpp. We then use that type
to create a temporary and we end up with a reg:QI rather than a reg:OO.
Is the casted pointer type supposed to be stripped away like that?
Anyway, I can work around that since I know what the temporary type should be
rather than stealing the type from the src operand.
