transformations in FunctionAttrs rather than building a new one each time. This isn't trivial because there are different heuristics from different passes for exactly what set they want. The primary difference is whether an *overridable* function completely disables the synthesis of attributes. I've modeled this by directly testing for overridable, and using the common set that excludes external and opt-none functions. This does cause some changes by disabling more optimizations in the face of opt-none. Specifically, we were still optimizing *calls* to opt-none functions based on their attributes, just not the bodies. It seems better to be conservative on both fronts given the intended semanticas here (best effort to not assume or disturb anything). I've not tried to test this change as it seems complex, brittle, and not important to the implicit contract of opt-none. Instead, it seems more like a choice that should be dictated by the simplified implementation and the change to be acceptable differences within the space of opt-none. A big benefit here is that these transformations no longer rely on the legacy pass manager's SCC types, they just work on generic sets of function pointers. This will make it easy to re-use their logic in the new pass manager. I've also made the transforms static functions instead of members where trivial while I was touching the signatures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@251640 91177308-0d34-0410-b5e6-96231b3b80d8 |
