[drlvm][jit][jet][x86-64] VM throws ArithmeticException during division on value which has
zero in low 32 bits.
---------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-4675
                 URL: https://issues.apache.org/jira/browse/HARMONY-4675
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Pavel Afremov
         Attachments: test.java

Following test fails on x86-64 platform.

public class test {
    public static void main(String[] args) {
        test lock = new test();
        lock.func();
    }

    private void func() {
	    try {
            long test_long = 0x000000ff00000000L;
            long res = test_long / test_long;
            System.out.println("PASSED No exception was thrown");
	    } catch (Throwable e) {
            System.out.println("FAILED Exception was thrown: " + e);
        }
    }
}

Looks like bug in JET.  On Interpreter and Opt test works OK. On the JET test throw arithmetic
exception with non zero divider.

Output is following:
1. RI
        $ java test
        PASSED No exception was thrown
2. DRLVM default
        $ ./drlvm/build/lnx_em64t_gcc_debug/deploy/jdk/jre/bin/java test
        FAILED Exception was thrown: java.lang.ArithmeticException
3. DRLVM interpreter
        $ ./drlvm/build/lnx_em64t_gcc_debug/deploy/jdk/jre/bin/java -Xint test
        PASSED No exception was thrown
4.DRLVM jet
        $ ./drlvm/build/lnx_em64t_gcc_debug/deploy/jdk/jre/bin/java -Xem:jet test
        FAILED Exception was thrown: java.lang.ArithmeticException
5 DRLVM opt
        $ ./drlvm/build/lnx_em64t_gcc_debug/deploy/jdk/jre/bin/java -Xem:opt test
        PASSED No exception was thrown
