Examples with ProfileBranchNode org.graalvm.compiler.hotspot.nodes.profiling.ProfileBranchNode used on opensource projects

Example 1 with ProfileBranchNode

use of org.graalvm.compiler.hotspot.nodes.profiling.ProfileBranchNode in project graal by oracle.

the class HotSpotProfilingPlugin method profileGoto.

@Override
public void profileGoto(GraphBuilderContext builder, ResolvedJavaMethod method, int bci, int targetBci, FrameState frameState) {
    assert shouldProfile(builder, method);
    OptionValues options = builder.getOptions();
    if (Options.ProfileBackedges.getValue(options) && targetBci <= bci) {
        ProfileNode p = builder.append(new ProfileBranchNode(method, backedgeNotifyFreqLog(options), backedgeProfilePobabilityLog(options), bci, targetBci));
        p.setStateBefore(frameState);
    }
}

Example 2 with ProfileBranchNode

use of org.graalvm.compiler.hotspot.nodes.profiling.ProfileBranchNode in project graal by oracle.

the class HotSpotProfilingPlugin method profileIf.

@Override
public void profileIf(GraphBuilderContext builder, ResolvedJavaMethod method, int bci, LogicNode condition, int trueBranchBci, int falseBranchBci, FrameState frameState) {
    assert shouldProfile(builder, method);
    OptionValues options = builder.getOptions();

        }
        ValueNode trueValue = builder.append(ConstantNode.forBoolean(!negate));
        ValueNode falseValue = builder.append(ConstantNode.forBoolean(negate));
        ConditionalNode branchCondition = builder.append(new ConditionalNode(condition, trueValue, falseValue));
        ProfileNode p = builder.append(new ProfileBranchNode(method, backedgeNotifyFreqLog(options), backedgeProfilePobabilityLog(options), branchCondition, bci, targetBci));
        p.setStateBefore(frameState);
    }
