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. llvm-svn: 195519 |
