Hi everybody, I'm trying to get loop hotness data across a suite (e.g. the llvm test-suite). Ideally, this would be a list that for each loop would list how many times it was entered and what was its iteration count (at least the latter). The closest thing I could come up with is: - clang -fprofile-instr-generate (without opts) to get a .profraw - Get the .profdata - Give that back to clang
