 class OutlineableChunkStart
extends MarkerInstruction

This pseudo-instruction marks the beginning of a region of byte code that can be copied into a new method, termed an "outlineable" chunk. The size of the Java stack must be the same at the start of the region as it is at the end of the region, any value on the stack at the start of the region must not be consumed by an instruction in the region of code, the region must not contain a return instruction, no branch instruction in the region is permitted to have a target that is outside the region, and no branch instruction outside the region is permitted to have a target that is inside the region.

The end of the region is marked by an OutlineableChunkEnd pseudo-instruction.

Such a region of code may contain other outlineable regions.
