+
+There was already a test case for landingpads to handle this case, but I
+had forgotten to consider PHI instructions preceding the EH_LABEL in the
+landingpad.

+Subject: [PATCH] Revert "[SCEV] add no wrap flag for SCEVAddExpr."
+
+This reverts r366419 because the analysis performed is within the context of
+the loop and it's only valid to add wrapping flags to "global" expressions if
+they're always correct.
