public Instr clone(CloneInfo ii) Implements abstract org.jruby.ir.instructions.Instr.clone. Doc from org.jruby.ir.instructions.Instr.clone. 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. Parameters ii:CloneInfo This object manages renaming of variables and labels, handles args and return values. Returns:Instr a new instruction that can be used in the target scope.

public Instr clone(CloneInfo ii)

Implements abstract org.jruby.ir.instructions.Instr.clone.

Doc from org.jruby.ir.instructions.Instr.clone.

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.

Parameters

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

Returns:Instr

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