Method Detail

allocateInterpreterContext

public InterpreterContext allocateInterpreterContext(java.util.List<Instr> instructions)

Description copied from class: IRScope

Make version specific to scope which needs it (e.g. Closure vs non-closure).

Overrides:

allocateInterpreterContext in class IRScope

allocateInterpreterContext

public InterpreterContext allocateInterpreterContext(java.util.concurrent.Callable<java.util.List<Instr>> instructions)

Description copied from class: IRScope

Make version specific to scope which needs it (e.g. Closure vs non-closure).

Overrides:

allocateInterpreterContext in class IRScope

setBeginEndBlock

public void setBeginEndBlock()

isBeginEndBlock

public boolean isBeginEndBlock()

Overrides:

isBeginEndBlock in class IRScope

getNextClosureId

public int getNextClosureId()

Overrides:

getNextClosureId in class IRScope

getNewFlipStateVariable

public LocalVariable getNewFlipStateVariable()

Overrides:

getNewFlipStateVariable in class IRScope

createTemporaryVariable

public TemporaryLocalVariable createTemporaryVariable()

Overrides:

createTemporaryVariable in class IRScope

getNewTemporaryVariable

public TemporaryLocalVariable getNewTemporaryVariable(TemporaryVariableType type)

Overrides:

getNewTemporaryVariable in class IRScope

getNewLabel

public Label getNewLabel()

Overrides:
