The fix attempt for
JDK-8272574 relied on improving the load split through phi optimization by rewiring pinned loads less conservatively. This, however, was not done correctly ( JDK-8277529). The fix for JDK-8277529 reverts the improved handling of JDK-8272574 because it did not fix the original root cause. This RFE should revisit the idea of JDK-8272574 to improve the control of pinned loads that are split through phis such that they do not end up between a loop and the predicates which prevents the application of loop predication.
