hoy added a comment.

Thanks for the change. Would be good to call out some rough numbers measured with our internal services.



================
Comment at: llvm/lib/Transforms/IPO/SampleProfile.cpp:2052
+    // Enable stale profile matching by default for CSSPGO.
+    if (!SalvageStaleProfile.getNumOccurrences())
+      SalvageStaleProfile = true;
----------------
Wrap this under a check of `profileIsPseudoProbed`?
