Class BoxNodeOptimizationPhase

org.graalvm.compiler.phases.common.BoxNodeOptimizationPhase

All Implemented Interfaces:

PhaseSizeContract

public class BoxNodeOptimizationPhase
extends PostRunCanonicalizationPhase<CoreProviders>

Try to replace box operations with dominating box operations. Consider the following code snippet:

 boxedVal1 = box(primitiveVal)
 ...
 boxedVal2 = box(primitiveVal)
 

which can be rewritten to (if the assignment to boxedVal1 dominates the assignment to boxedVal2)

 boxedVal1 = box(primitiveVal)
 ...
 boxedVal2 = boxedVal1;
