Only using that change in StringRef already decreases the number of preoprocessed lines from 7837621 to 7776151 for LLVMSupport Perhaps more interestingly, it shows that many files were relying on the inclusion of StringRef.h to have the declaration from STLExtras.h. This patch tries hard to patch relevant part of llvm-project impacted by this hidden dependency removal. Potential impact: - "llvm/ADT/StringRef.h" no longer includes <memory>, "llvm/ADT/Optional.h" nor "llvm/ADT/STLExtras.h" Related Discourse thread: https://llvm.discourse.group/t/include-what-you-use-include-cleanup/5831
