--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue is that VECTOR_CST_NELTS does not fit 32bits but RTX vectors have int
sizes.
I suggest to limit the vector_size attribute argument accordingly.
Also a better failure mode might be to make the rtvec_alloc size argument
size_t and ICE on a size that doesn't fit an int rather than silently
truncating.
