Thanks, Richard. I will file a bug report and prepare a complete patch. For
perm_mask_for_reverse function, should I move it before vectorizable_store or
add a declaration.
Move it.

Hi,
I was looking at some loops that can be vectorized by LLVM, but not GCC. One
type of loop is with store of negative step.
void test1(short * __restrict__ x, short * __restrict__ y, short * __restrict__
z)
{
int i;
for (i=127; i>=0; i--) {
x[i] = y[127-i] + z[127-i];
}
}
