manager. This starts to allow us to test analyses more easily, but it's really only the beginning. Some of the code here is still untestable without manual changes to create analysis passes, but I wanted to factor it into a small of chunks as possible. Next up in order to be able to test things are, in no particular order: - No-op analyses passes so we don't have to use real ones to exercise the pass maneger itself. - Automatic way of generating dummy passes that require an analysis be run, including a variant that calls a 'print' method on a pass to make it even easier to print out the results of an analysis. - Dummy passes that invalidate all analyses for their IR unit so we can test invalidation and re-runs. - Automatic way to print each analysis pass as it is re-run. - Automatic but optional verification of analysis passes everywhere possible. I'm not claiming I'll get to all of these immediately, but that's what is in the pipeline at some stage. I'm fleshing out exactly what I need and what to prioritize by working on converting analyses and then trying to test the conversion. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225162 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.
