--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Sounds like gimple folding issue.
We have:
vect__4.9_31 = (vector(4) float) { 0, 1, 2, 3 };
vect__5.10_32 = (vector(4) unsigned int) vect__4.9_31;
where the first stmt's rhs_code is FLOAT_EXPR and rhs1 is VECTOR_CST vector(4)
int, and the second stmt's rhs_code is FIX_TRUNC_EXPR.
So, for this combined together we should use VIEW_CONVERT_EXPR, but we use
FIX_TRUNC_EXPR.
