+Subject: [PATCH] JIT: Add missing {STORE|LOAD}_ACC() to CreateCallContext
+
+We cannot assume anything about the accumulator register after calling
+PushCallContext::call(). Also add a note about not needing to re-load
+the accumulator on ThrowException.
+
+Pick-to: 6.5 6.2 5.15
+Fixes: QTBUG-111935
