[PATCH] D116051: [InstrProf] Prevent duplicate functions in correlated data

[Kyungwoo Lee via Phabricator via llvm-commits]

kyulee added a comment.

I presume without debug-info related correlation (normal IRPGO), the metadata is merged by their linkage types/contents.
For my education, I wonder whether IRPGO might have the same named function with different different CFG shapes -- e.g., static functions.
This approach seems to pick the first appearance of metadata for the same named functions, and ignore the rest assuming they are all identical.
And also can we have a test case for this?
