      Description

      jtreg -javaoption:-XX:+EnableValhallaC1 -javaoption:-XX:TieredStopAtLevel=1 Ifacmp.java

      http://hg.openjdk.java.net/valhalla/valhalla/file/2b098533f1e5/test/hotspot/jtreg/runtime/valhalla/valuetypes/Ifacmp.java

      The following test case fails:

          public void testLocalValues() {
              // "aload + ifacmp" should be same as "aaload + ifamcp"
              // but let's be paranoid...
              MyValue a = new MyValue(11);
              MyValue b = new MyValue(11);
              MyValue c = a;
              MyValue a1 = new MyValue(7);
              MyValue2 a2 = new MyValue2(13);

              if (acmpModeInlineAlwaysFalse) {
                  if (a == b) throw new RuntimeException("Always false fail " + a + " == " + b);
                  if (a == c) throw new RuntimeException("Always false fail " + a + " == " + c);
              } else {
      FAIL>> if (a != b) throw new RuntimeException("Substitutability test failed" + a + " != " + b);
                  if (a != c) throw new RuntimeException("Substitutability test failed");
              }
              if (a == a1) throw new RuntimeException();
              checkEqual(a, a2, false);
          }
