process
Given an L2Instruction from the source L2ControlFlowGraph, start translating and emitting to the target graph from that point, until nothing else is reachable. Process any encountered back-edges after all forward edges and blocks have completed.
The client must set up the targetGenerator to be generating at a reachable state, prior to this call.
Parameters
starting
The L2Instruction of the source control flow graph from which to start translation and code generation.
