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.

cloneForBlockCloning

public Instr cloneForBlockCloning(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction so it can be used in a cloned block which is present in a scope that itself or an ancestor scope (in the case of nested blocks) is being inlined. This requires renaming variables to eliminate naming conflicts. Labels need not be renamed.

Overrides:

cloneForBlockCloning 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
