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

the class HotSpotGraalCompiler method configGraphBuilderSuite.

/**
 * Reconfigures a given graph builder suite (GBS) if one of the given GBS parameter values is
 * not the default.
 *
 * @param suite the graph builder suite
 * @param shouldDebugNonSafepoints specifies if extra debug info should be generated (default is
 *            false)
 * @param isOSR specifies if extra OSR-specific post-processing is required (default is false)
 * @return a new suite derived from {@code suite} if any of the GBS parameters did not have a
 *         default value otherwise {@code suite}
