[PATCH] D31345: [XRay] [compiler-rt] Unwriting FDR mode buffers when functions are short.

[Keith via Phabricator via llvm-commits]

kpw added a comment.

I am making some headway. My understanding is that FDR logging short circuits when the log is finalizing or finalized without returning the buffer and is currently depending on the thread exit destructor to release the buffer.

This does not seem ideal, and I have a fix for that, but I'm going to iterate on it a bit to see if I can simplify the logic and make sure I account for edge cases so that nothing is logged after the EOB is written and the buffer is closed.
