> This patch contains the following changes:
> 1) All previously hardcoded parameters used by devirt and unguard optimization passes could be set up from command line.
> 2) Unguard pass is usable from now. Now it processes edge profile correctly. I hope we add profile guided unguarding to the server path after this fix commited. It shows ~1-2% performance improvement on some benchmarks.
> 3) Profile guided devirtualization of object (not interface) methods added.
