Example 16 with OptimizedCallTarget

use of org.graalvm.compiler.truffle.runtime.OptimizedCallTarget in project graal by oracle.

         * 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
