--- Comment #1 from Alice Carlotti <acarlotti at gcc dot gnu.org> ---
Is the issue that you can't use a vector constructor to directly concatenate
two vectors in GIMPLE? That is, the following is invalid:
_7 = {b_5(D), { 0, 0, 0, 0 }}
If so, then what's the canonical way to represent vector concatenation in
GIMPLE? VEC_PERM_EXPR?
(Incidentally, I think this bug is from the first patch I ever worked on in
GCC.)
