[PATCH] D136698: [SampleFDO] Persist profile staleness metrics into binary

[Wenlei He via Phabricator via llvm-commits]

wenlei added inline comments.


================
Comment at: llvm/lib/MC/MCObjectFileInfo.cpp:534
       Ctx->getELFSection(".pseudo_probe_desc", DebugSecType, 0);
+  ProfStatsSection = Ctx->getELFSection(".prof_stats", DebugSecType, 0);
 }
----------------
prof_stats might still be a bit narrow. persistent key-value in obj can be a general mechanism used for other purpose as well. maybe `llvm-stats`?
