Orlando added a comment.

> My take-away from the discussion was this: It is desirable to map the instructions to something in the loop (e.g., not line 0), unless doing so will provide confusing information to the mapping that PGO uses to optimize the relevant branches. Am I correct in saying that this latter issue is of minimal concern in this case?

As far as I see it you are correct. There should be negligible to no impact on PGO.
