Description
In PhaseIdealLoop::create_outer_strip_mined_loop():
while (be->is_Store() && old_new[be->_idx] != NULL) {
ShouldNotReachHere();
be = be->in(MemNode::Memory);
}
and
while (be->is_Store() && old_new[be->_idx] != NULL) {
ShouldNotReachHere();
be = be->in(MemNode::Memory);
}
This code would trigger with sunk stores and stores on backedge. I couldn't trigger it with a test case and it wasn't caught by testing. Still, if this happens in the wild it would cause a crash.
