This moves most of GlobalOpt's constructor optimization code out of GlobalOpt into Transforms/Utils/CDtorUtils.{h,cpp}. The public interface is a single function OptimizeGlobalCtorsList() that takes a predicate returning which constructors to remove. GlobalOpt calls this with a function that statically evaluates all constructors, just like it did before. This part of the change is behavior-preserving. Also add a call to this from GlobalDCE with a filter that removes global constructors that contain a "ret" instruction and nothing else – this fixes PR19590. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207856 91177308-0d34-0410-b5e6-96231b3b80d8 |
