RFC: Reducing Instr PGO size overhead
...patch is doing. The key type before the change is StringRef, while the after the key type is uint64_t. Are you suggesting treating uint64_t md5 sum key as a string of 8 bytes or storing md5 has in text form which will double the size? In the raw format, md5 sum key can be an embedded field in the prf_data variable instead of as different var referenced by prf_data. > > If this is not the case, you should show your current patch so that we can > discuss things concretely.
