Thanks for double checking. I noticed the ICP and stale profile tolerance discussions when read the Phab history; it's good Phab review history are still available nowadays. IRPGO profiles could be used along with supplementary sample-pgo profiles. I'll probably read relevant code in llvm-profdata to understand how these interact in theory mostly for my own curiosity (hopefully no rough edges as long as `llvm-profdata` uses the same pgo name format used by latest compiler) https://github.com/llvm/llvm-project/pull/74008 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
