GCC documentation for AutoFDO points to create_gcov tool that converts perf.data file into gcov format that can be consumed by gcc with -fauto-profile (https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html, https://gcc.gnu.org/wiki/AutoFDO/Tutorial).
I noticed that the source code for create_gcov has been deleted from https://github.com/google/autofdo on April 7. I asked about that change in that repo and got the following reply: https://github.com/google/autofdo/pull/107#issuecomment-819108738 "Actually we didn't use create_gcov and havn't updated create_gcov for years, and we also didn't have enough tests to guarantee it works (It was gcc-4.8 when we used and verified create_gcov). If you need it, it is welcomed to update create_gcov and add it to the respository." Does this mean that AutoFDO is currently dead in gcc? Thanks, Eugene
