Method Detail

getPreAllocationOptimizationStage

public LIRPhaseSuite<PreAllocationOptimizationPhase.PreAllocationOptimizationContext> getPreAllocationOptimizationStage()

PreAllocationOptimizationPhases are executed between LIR generation and register allocation.

Implementers can create new variables, stack slots and virtual stack slots.

getAllocationStage

public LIRPhaseSuite<AllocationPhase.AllocationContext> getAllocationStage()

AllocationPhases are responsible for register allocation and translating VirtualStackSlots into StackSlots.

After the AllocationStage there should be no more Variables and VirtualStackSlots.

getPostAllocationOptimizationStage

public LIRPhaseSuite<PostAllocationOptimizationPhase.PostAllocationOptimizationContext> getPostAllocationOptimizationStage()

PostAllocationOptimizationPhases are executed after register allocation and before the final analysis stage that precedes machine code generation.

A PostAllocationOptimizationPhase must not introduce new Variables, VirtualStackSlots or StackSlots. Blocks might be removed from LIR.codeEmittingOrder() by overwriting them with null.

getFinalCodeAnalysisStage

public LIRPhaseSuite<FinalCodeAnalysisPhase.FinalCodeAnalysisContext> getFinalCodeAnalysisStage()

FinalCodeAnalysisPhases are executed after post-allocation optimizations and before machine code generation.

A FinalCodeAnalysisPhase must not modify the code in any way but may verify properties of the code or compute metadata like ReferenceMaps.

isImmutable

public boolean isImmutable()

setImmutable

public void setImmutable()

copy
