Take the following example:
typedef __attribute__ ((vector_size (16))) float v4sf;
typedef __attribute__ ((vector_size (16))) int v4si;
v4sf t;
void
foo (float t1)
{
t = (v4sf)(v4si){1,1,1,1};
t+=t;
}
------
There should be no lvx in it but there is currently because VIEW_CONVERT_EXPR
is foldded at the tree level now.
