[PATCH] D93254: [NFC][SampleFDO] Preparation to support multiple sections with the same type in ExtBinary format.

[Hongtao Yu via Phabricator via llvm-commits]

hoy added a comment.

Can you please shed light on how multiple same-typed sections will be used? Thanks.



================
Comment at: llvm/lib/ProfileData/SampleProfWriter.cpp:250
     const StringMap<FunctionSamples> &ProfileMap) {
-  if (auto EC = writeOneSection(SecProfSummary, ProfileMap))
+  if (auto EC = writeOneSection(SecProfSummary, 0, ProfileMap))
     return EC;
----------------
How are the constant indices determined? I'm wondering if it's possible to automatically assign indices to avoid collision.
