This was originally a pointer to support pass managers which didn't use AnalysisManagers. However, that doesn't realistically come up much and the complexity of supporting it doesn't really make sense. In fact, *many* parts of the pass manager were just assuming the pointer was never null already. This at least makes it much more explicit and clear. llvm-svn: 263219 |
