Examples with IntegerTestNode org.graalvm.compiler.nodes.calc.IntegerTestNode used on opensource projects

Example 1 with IntegerTestNode

use of org.graalvm.compiler.nodes.calc.IntegerTestNode in project graal by oracle.

the class CompareCanonicalizerTest method testIntegerTest.

@Test
public void testIntegerTest() {
    for (int i = 1; i <= 4; i++) {
        StructuredGraph graph = getCanonicalizedGraph("integerTest" + i);
        ReturnNode returnNode = (ReturnNode) graph.start().next();
        ConditionalNode conditional = (ConditionalNode) returnNode.result();
        IntegerTestNode test = (IntegerTestNode) conditional.condition();
        ParameterNode param0 = graph.getParameter(0);
        ParameterNode param1 = graph.getParameter(1);
        assertTrue((test.getX() == param0 && test.getY() == param1) || (test.getX() == param1 && test.getY() == param0));
    }
}

Example 2 with IntegerTestNode

use of org.graalvm.compiler.nodes.calc.IntegerTestNode in project graal by oracle.
