Hey, I just read through this paper. The phase ordering issues are currently based on heuristics. I noticed that you're only using the instruction count of LLVM as the measurement. However, this metric might not accurately reflect the program's actual performance and code size. LLVM has instructions like GEP that can translate into several lines of assembly code. Additionally, I suggest trying to run some large benchmarks like SPEC to demonstrate the performance benefits of using the LLM.
