Abstract/s
We present an Instrumentation - Based Profile Guided Optimization (PGO) technique that produces contextual profiles. When applied to a real production binary, it proves competitive when compared to tip-of-tree instrumented PGO in: binary size, runtime and memory overhead, and resulting profile size. We conclude with challenges and possible approaches to incorporating contextual profiles "wholeheartedly" in LLVM.
