Example 5 with ParameterNode

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

the class ForeignCallStub method getGraph.

/**
 * Creates a graph for this stub.
 * <p>
 * If the stub returns an object, the graph created corresponds to this pseudo code:
 *
 * <pre>
 *     Object foreignFunctionStub(args...) {
 *         foreignFunction(currentThread,  args);
 *         if (clearPendingException(thread())) {
 *             getAndClearObjectResult(thread());
 *             DeoptimizeCallerNode.deopt(InvalidateReprofile, RuntimeConstraint);
 *         }
 *         return verifyObject(getAndClearObjectResult(thread()));
 *     }
 * </pre>
 *
 * If the stub returns a primitive or word, the graph created corresponds to this pseudo code
 * (using {@code int} as the primitive return type):
 *
 * <pre>
 *     int foreignFunctionStub(args...) {
 *         int result = foreignFunction(currentThread,  args);
 *         if (clearPendingException(thread())) {
 *             DeoptimizeCallerNode.deopt(InvalidateReprofile, RuntimeConstraint);
 *         }
 *         return result;
 *     }
 * </pre>
 *
 * If the stub is void, the graph created corresponds to this pseudo code:
 *
 * <pre>
 *     void foreignFunctionStub(args...) {
 *         foreignFunction(currentThread,  args);
 *         if (clearPendingException(thread())) {
 *             DeoptimizeCallerNode.deopt(InvalidateReprofile, RuntimeConstraint);
 *         }
 *     }
 * </pre>
 *
 * In each example above, the {@code currentThread} argument is the C++ JavaThread value (i.e.,
 * %r15 on AMD64) and is only prepended if {@link #prependThread} is true.
