Examples with HIRLoop org.graalvm.compiler.nodes.cfg.HIRLoop used on opensource projects

Example 1 with HIRLoop

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

the class FloatingReadPhase method run.

@Override
@SuppressWarnings("try")
protected void run(StructuredGraph graph) {
    EconomicMap<LoopBeginNode, EconomicSet<LocationIdentity>> modifiedInLoops = null;
    if (graph.hasLoops()) {
        modifiedInLoops = EconomicMap.create(Equivalence.IDENTITY);
        ControlFlowGraph cfg = ControlFlowGraph.compute(graph, true, true, false, false);
        for (Loop<?> l : cfg.getLoops()) {
            HIRLoop loop = (HIRLoop) l;
            processLoop(loop, modifiedInLoops);
        }
    }
    HashSetNodeEventListener listener = new HashSetNodeEventListener(EnumSet.of(NODE_ADDED, ZERO_USAGES));
    try (NodeEventScope nes = graph.trackNodeEvents(listener)) {
        ReentrantNodeIterator.apply(new FloatingReadClosure(modifiedInLoops, createFloatingReads, createMemoryMapNodes), graph.start(), new MemoryMapImpl(graph.start()));
    }
    for (Node n : removeExternallyUsedNodes(listener.getNodes())) {
        if (n.isAlive() && n instanceof FloatingNode) {
            n.replaceAtUsages(null);
            GraphUtil.killWithUnusedFloatingInputs(n);
        }
    }
    if (createFloatingReads) {
        assert !graph.isAfterFloatingReadPhase();
        graph.setAfterFloatingReadPhase(true);
    }
}

Example 2 with HIRLoop

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

the class FloatingReadPhase method processLoop.

private EconomicSet<LocationIdentity> processLoop(HIRLoop loop, EconomicMap<LoopBeginNode, EconomicSet<LocationIdentity>> modifiedInLoops) {
    LoopBeginNode loopBegin = (LoopBeginNode) loop.getHeader().getBeginNode();
    EconomicSet<LocationIdentity> result = modifiedInLoops.get(loopBegin);
    if (result != null) {
        return result;
    }
    result = EconomicSet.create(Equivalence.DEFAULT);
    for (Loop<Block> inner : loop.getChildren()) {
        result.addAll(processLoop((HIRLoop) inner, modifiedInLoops));
    }
    for (Block b : loop.getBlocks()) {
        if (b.getLoop() == loop) {
            processBlock(b, result);
        }
    }
    modifiedInLoops.put(loopBegin, result);
    return result;
}
