Example 3 with ResolvedJavaSymbol

use of org.graalvm.compiler.nodes.graphbuilderconf.InvocationPlugins.ResolvedJavaSymbol in project graal by oracle.

the class TruffleGraphBuilderPlugins method registerFrameAccessors.

/**
 * We intrinsify the getXxx, setXxx, and isXxx methods for all type tags. The intrinsic nodes
 * are lightweight fixed nodes without a {@link FrameState}. No {@link FrameState} is important
 * for partial evaluation performance, because creating and later on discarding FrameStates for
 * the setXxx methods have a high compile time cost.
 *
 * Intrinsification requires the following conditions: (1) the accessed frame is directly the
 * {@link NewFrameNode}, (2) the accessed FrameSlot is a constant, and (3) the FrameDescriptor
 * was never materialized before. All three conditions together guarantee that the escape
 * analysis can virtualize the access. The condition (3) is necessary because a possible
 * materialization of the frame can prevent escape analysis - so in that case a FrameState for
 * setXxx methods is actually necessary since they stores can be state-changing memory
 * operations.
 *
 * Note that we do not register an intrinsification for {@code FrameWithoutBoxing.getValue()}.
 * It is a complicated method to intrinsify, and it is not used frequently enough to justify the
 * complexity of an intrinsification.
