Example 16 with WriteNode

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

the class MemoryScheduleTest method testBlockSchedule.

@Test
public void testBlockSchedule() {
    ScheduleResult schedule = getFinalSchedule("testBlockScheduleSnippet", TestMode.WITHOUT_FRAMESTATES);
    StructuredGraph graph = schedule.getCFG().graph;
    NodeIterable<WriteNode> writeNodes = graph.getNodes().filter(WriteNode.class);
    assertDeepEquals(1, schedule.getCFG().getBlocks().length);
    assertDeepEquals(8, writeNodes.count());
    assertDeepEquals(1, graph.getNodes().filter(FloatingReadNode.class).count());
    FloatingReadNode read = graph.getNodes().filter(FloatingReadNode.class).first();
    WriteNode[] writes = new WriteNode[8];
    int i = 0;
    for (WriteNode n : writeNodes) {
        writes[i] = n;
        i++;
    }
    assertOrderedAfterSchedule(schedule, writes[4], read);
    assertOrderedAfterSchedule(schedule, read, writes[5]);
    for (int j = 0; j < 7; j++) {
        assertOrderedAfterSchedule(schedule, writes[j], writes[j + 1]);
    }
}

Example 17 with WriteNode
