when all are being preserved. We want to short-circuit this for a couple of reasons. One, I don't really want passes to grow a dependency on actually receiving their invalidate call when they've been preserved. I'm thinking about removing this entirely. But more importantly, preserving everything is likely to be the common case in a lot of scenarios, and it would be really good to bypass all of the invalidation and preservation machinery there. Avoiding calling N opaque functions to try to invalidate things that are by definition still valid seems important. =] This wasn't really inpsired by much other than seeing the spam in the logging for analyses, but it seems better ot get it checked in rather than forgetting about it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225163 91177308-0d34-0410-b5e6-96231b3b80d8

; This test is essentially doing very basic things with the opt tool and the
|
|
; new pass manager pipeline. It will be used to flesh out the feature
|
|
; completeness of the opt tool when the new pass manager is engaged. The tests
|
|
; may not be useful once it becomes the default or may get spread out into other
|
|
; files, but for now this is just going to step the new process through its
|
|
; paces.
