[PATCH] D146452: [AutoFDO] Use flattened profiles for profile staleness metrics

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Document the new llvm-profdata option in the Commandline guide.



================
Comment at: llvm/include/llvm/ProfileData/SampleProf.h:1288
+  ProfileConverter(SampleProfileMap &Profiles);
+  // CSProfileConverter converts a full context-sensitive flat sample profile
+  // into a nested context-sensitive sample profile.
----------------
Remove 'CS'


================
Comment at: llvm/lib/Transforms/IPO/SampleProfile.cpp:145
+    cl::desc(
+        "Use flattened profile for stale profile detection and matching."));
+
----------------
Can you add a test case of using the new option for state profile detection?
