Not surprise: Richard's check-in of the MISALIGNED_INDIRECT_REF removal
fixed the bug.
Surprise: only two prefetches are generated (which is right). However,
if we could align the references as the following case (PR 45021):
float a[1024], b[1024];
void foo(int beta)
{
int i;
for(i=0; i<1024; i++)
a[i] = a[i] + beta * b[i];
}
Three prefetches will be generated, one for b, one for load a, and one for
store a.
Anyway, I am closing this bug, and we should work on PR 45021.
