Duncan, Justin, I'm about to submit a series of patches that add writing capabilities for sample profiles in both text and binary formats. Soon, I'll add a third format (to make it interoperable with GCC). I would like to add some profile maintenance utilities as well: merging, dumping and converting. It seems like the best place would be tools/llvm-profdata. But that means that I need

Hi, The problem we're trying to address: PGO transforms that are based on block counts need some way to answer isHotBlock() query. A simple comparison of the form block_count > N, for some constant N is not useful since even for the same program different profile inputs can cause different answers for isHotBlock() on the same block. This can be addressed by comparing against a reference
