# Test performs a BB reordering with unsupported # instruction jrcxz. Reordering works correctly with the # follow options: None, Normal or Reverse. Other strategies # are completed with Assertion `isIntN(Size * 8 + 1, Value). # The cause is the distance between BB where one contains # jrcxz instruction. # Example: OpenSSL #
