[cfe-dev] Finding Code that Counts with Causal Profiling

Hi Mayuresh,

I skimmed the paper and it seems interesting. I have one high-level
question: how relevant is this technique to conventional single-threaded
compilers? There's some mention of being able to account for system
operations (e.g., IO), but It's not clear to me if the tool is of any use
for profiling LLVM-based compilers.
