getLabel

public Label getLabel()

clone

public Instr clone(CloneInfo ii)

Description copied from class: Instr

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Specified by:

clone in class Instr

Parameters:

ii - This object manages renaming of variables and labels, handles args and return values.

Returns:

a new instruction that can be used in the target scope.

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Instr

decode

public static LabelInstr decode(IRReaderDecoder d)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
