1. A system, comprising: a compiler that compiles source-level code to generate an intermediate-level instruction comprising a predetermined component, said intermediate-level instruction an at least partially optimized version of the source-level code; wherein execution of the predetermined component triggers the execution of a series of instructions that, when executed, generates previously-unavailable data that is used to re-generate the intermediate-level instruction; wherein the re-generated intermediate-level instruction has a length less than or equal to that of the intermediate-level instruction.
