--- 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.

rs6000: Don't ICE when we disassemble an MMA variable [PR101322]
When we expand an MMA disassemble built-in with C++ using a pointer that
is cast to a valid MMA type, the type isn't passed down to the expand
machinery and we end up using the base type of the pointer which leads to
an ICE. This patch enforces we always use the correct MMA type regardless
of the pointer type being used.
