Examples with FrameDescriptor com.oracle.truffle.api.frame.FrameDescriptor used on opensource projects

Example 31 with FrameDescriptor

use of com.oracle.truffle.api.frame.FrameDescriptor in project graal by oracle.

the class SimplePartialEvaluationTest method synchronizedExceptionMerge.

@Test
public void synchronizedExceptionMerge() {
    /*
         * Multiple non-inlineable methods with exception edges called from a synchronized method
         * lead to a complicated Graal graph that involves the BytecodeFrame.UNWIND_BCI. This test
         * checks that partial evaluation handles that case correctly.

    Assert.assertEquals(42, compilable.call(new Object[0]));
}

Example 32 with FrameDescriptor

use of com.oracle.truffle.api.frame.FrameDescriptor in project graal by oracle.

the class SimplePartialEvaluationTest method intrinsicVirtual.

@Test
public void intrinsicVirtual() {
    /*
         * The intrinsic for String.equals() is inlined late during Truffle partial evaluation,
         * because we call equals() on a value that has the static type Object, but during partial
