Chandler Carruth 17395fa733 [PM] Add a utility pass template that synthesizes the invalidation of ... a specific analysis result. This is quite handy to test things, and will also likely be very useful for debugging issues. You could narrow down pass validation failures by walking these invalidate pass runs up and down the pass pipeline, etc. I've added support to the pass pipeline parsing to be able to create one of these for any analysis pass desired. Just adding this class uncovered one latent bug where the AnalysisManager CRTP base class had a hard-coded Module type rather than using IRUnitT. I've also added tests for invalidation and caching of analyses in a basic way across all the pass managers. These in turn uncovered two more bugs where we failed to correctly invalidate an analysis -- its results were invalidated but the key for re-running the pass was never cleared and so it was never re-run. Quite nasty. I'm very glad to debug this here rather than with a full system. Also, yes, the naming here is horrid. I'm going to update some of the names to be slightly less awful shortly. But really, I've no "good" ideas for naming. I'll be satisfied if I can get it to "not bad". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225246 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-06 04:49:44 +00:00
