Overrides org.jruby.ir.instructions.CallInstr.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).

Does this instruction do anything the scope is interested in?

public Instr clone(CloneInfo ii)

Overrides org.jruby.ir.instructions.CallInstr.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.

Returns:boolean
