Load the block passed to this scope via the on-heap frame (or similar cross-call structure). This is typically used to access the "yieldable" target for blocks and evals. Only used when within a scope that will use an on-heap frame.

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).

public Instr clone(CloneInfo info)

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
info: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
