toString

public String toString()

Overrides:

toString in class ReturnBase

cloneForInlining

public Instr cloneForInlining(InlinerInfo 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 requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlining 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.

cloneForInlinedScope

public Instr cloneForInlinedScope(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction (present in a method/closure) so it can be inlined into another scope. This requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlinedScope in class Instr

Returns:

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

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
