Example 14 with CanonicalizerPhase

use of org.graalvm.compiler.phases.common.CanonicalizerPhase in project graal by oracle.

the class EscapeAnalysisTest method testRemovalSpecialCase.

/**

 * phi need to be recognized as an important change. This needs a loop so that the allocation is
 * not trivially removed by dead code elimination.

    Assert.assertEquals(2, graph.getNodes().filter(CommitAllocationNode.class).count());

}
