Chandler Carruth 4d32e85359 [PM] Switch the downward invalidation to be incremental where only the ... one function's analyses are invalidated at a time. Also switch the preservation of the proxy to *fully* preserve the lower (function) analyses. Combined, this gets both upward and downward analysis invalidation to a point I'm happy with: - A function pass invalidates its function analyses, and its parent's module analyses. - A module pass invalidates all of its functions' analyses including the set of which functions are in the module. - A function pass can preserve a module analysis pass. - If all function passes preserve a module analysis pass, that preservation persists. If any doesn't the module analysis is invalidated. - A module pass can opt into managing *all* function analysis invalidation itself or *none*. - The conservative default is none, and the proxy takes the maximally conservative approach that works even if the set of functions has changed. - If a module pass opts into managing function analysis invalidation it has to propagate the invalidation itself, the proxy just does nothing. The only thing really missing is a way to query for a cached analysis or nothing at all. With this, function passes can more safely request a cached module analysis pass without fear of it accidentally running part way through. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195519 91177308-0d34-0410-b5e6-96231b3b80d8		2013-11-22 23:38:07 +00:00
