Method Detail

codeSizeIncrease

public float codeSizeIncrease()

Description copied from interface: PhaseSizeContract

Returns a factor >=1 that determines what the final code size in terms of the sum of the node code sizes NodeSize of all nodes is.

Specified by:

codeSizeIncrease in interface PhaseSizeContract

Overrides:

codeSizeIncrease in class BasePhase<CoreProviders>

Returns:

a factor that determines how much the code size can be increased by this phase

protected void processBlock(Block b,
                            org.graalvm.collections.EconomicSet<org.graalvm.word.LocationIdentity> currentState)

run

protected void run(StructuredGraph graph,
                   CoreProviders context)

Specified by:
