FloatingReadPhase

public FloatingReadPhase()

FloatingReadPhase

public FloatingReadPhase(boolean createFloatingReads,
                         boolean createMemoryMapNodes)

Parameters:

createFloatingReads - specifies whether FloatableAccessNodes like ReadNode should be converted into floating nodes (e.g., FloatingReadNodes) where possible

createMemoryMapNodes - a MemoryMapNode will be created for each return if this is true
