Example 1 with ObjectCloneNode

use of org.graalvm.compiler.hotspot.replacements.ObjectCloneNode in project graal by oracle.

the class HotSpotGraphBuilderPlugins method registerObjectPlugins.

private static void registerObjectPlugins(InvocationPlugins plugins, OptionValues options, BytecodeProvider bytecodeProvider) {

    if (!GeneratePIC.getValue(options)) {
        // FIXME: clone() requires speculation and requires a fix in here (to check that
        // b.getAssumptions() != null), and in ReplacementImpl.getSubstitution() where there is
        // an instantiation of IntrinsicGraphBuilder using a constructor that sets
        // AllowAssumptions to YES automatically. The former has to inherit the assumptions
        // settings from the root compile instead. So, for now, I'm disabling it for
        // GeneratePIC.
        r.register1("clone", Receiver.class, new InvocationPlugin() {

            @Override
