Example 1 with ReplaceConstantNodesPhase

use of org.graalvm.compiler.hotspot.phases.aot.ReplaceConstantNodesPhase in project graal by oracle.

the class HotSpotSuitesProvider method createSuites.

@Override

    Suites ret = defaultSuitesCreator.createSuites(options);
    if (ImmutableCode.getValue(options)) {
        // lowering introduces class constants, therefore it must be after lowering
