--- Comment #5 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
https://arm-software.github.io/acle/main/acle.html#vector-data-types says:

"Not all types can be used in all operations. Generally, the operations
available on a type correspond to the operations available on the corresponding
scalar type."

But there is no corresponding scalar type for poly128_t (we don't support
128-bit data integers on 32-bit targets), so the compiler does not need to
support this case.

It still shouldn't crash, however, so this is still an ice-on-invalid-code bug.
