> Should already be handled by vectorizing the CTOR.
I've tried:
typedef int __attribute__((vector_size(16))) V;
V
foo (short *a)
{
return (V){a[0], a[1], a[2], a[3]};
}
V
bar (int *a)
{
return (V){a[0], a[1], a[2], a[3]};
}
and we don't do a vector (unaligned) read even in bar with -O3
-fno-tree-slp-vectorize, it is just SLP vectorization that makes it vectorize.
If we should handle foo as convertvector, we should handle bar in the same spot
as vector load from memory.
