...nary samples back to IR, similar to instrumentation PGO, but without any measure-able runtime overhead that is usually associated with instrumentation. We have a functioning implementation for the new CSSPGO now. Initial results on SPEC2006 shows ~2% geomean performance win on top of AutoFDO (with MonoLTO and NewPM) and ~4% .text size reduction at the same time. Motivation AutoFDO is a big success as it lowers the entry barrier for PGO significantly while still delivering substantial performance boost. However, there’s still a gap between AutoFDO and its instrumentation counterpart. From several f...
