Gets the keyword arg (or representation of what might be holding keyword args). The result of this is passed into the other keyword arg instructions to get what those instrs are interested in. One intent of this result is that it can be mutable so it can toggle off keyword arg flags early in the method before any exceptions or side-effects in the method can occur. It also can remove key/value pairs as individual keyword instructions execute. After all individual instructions have executed anything left is either kwrest or an arity error.

Implements abstract 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).

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.
