public class KillStackRange
extends Instruction

Delete all the values from the current stack frame apart from the m bottom-most items and the n top-most items.

popAll is the same as killStackRange 0 0, and you can build a simulated stack frame of n items (minus the calling information) using killStackRange 0 n

v0 ... vm-1 ... vk-n ... vk-1 m n v0 ... vm-1 vk-n ... vk-1
