Otherwise the numbers will likely do more harm than good, as they will significantly misattribute runtime. Fortunately, I think that should only require some relatively small changes to the LLVM timer infrastructure.


JFYI: the given patch introduces non-recursive (self-overlaps) timers only. I'm going to introduce self-overlaps timers when  https://reviews.llvm.org/D45619 is committed.
