org.graalvm.compiler.lir.phases.PreAllocationOptimizationPhase

org.graalvm.compiler.lir.constopt.ConstantLoadOptimization

public final class ConstantLoadOptimization
extends PreAllocationOptimizationPhase

This optimization tries to improve the handling of constants by replacing a single definition of a constant, which is potentially scheduled into a block with high frequency, with one or more definitions in blocks with a lower frequency.
