[llvm-dev] Status of the New Pass Manager

[Philip Reames via llvm-dev]

For our downstream usage, we've switched entirely to the new pass 
manager.  We made the switch a couple of months ago.  All of our testing 
is being done with the NPM, and we're about to start deleting 
(downstream) code which was only needed by the legacy pass manager.

I believe several other major contributors are in the same state.  We 
really need to get upstream switched over so that all of the community's 
testing efforts are aligned again.
