Example 1 with ObjectHashCodeNode

use of org.graalvm.compiler.truffle.test.nodes.ObjectHashCodeNode in project graal by oracle.

the class SimplePartialEvaluationTest method intrinsicHashCode.

         * The intrinsic for Object.hashCode() is inlined late during Truffle partial evaluation,
         * because we call hashCode() on a value whose exact type Object is only known during
         * partial evaluation.
