rnk added a comment. Regarding the alias attribute, it occurs to me that reimplementing this as an early LLVM pass would not have that problem. Do you think that would be worth doing?

Would the file prefix map not already have been applied when creating the LLVM IR module source file path? I think it should be, so I'm not sure the new code you added is in the right place. ================ Comment at: clang/lib/CodeGen/CodeGenModule.h:31 #include "clang/Basic/XRayLists.h" +#include "clang/Lex/PreprocessorOptions.h" #include "llvm/ADT/DenseMap.h" ---------------- Why add this include here? I don't see any reason it is needed. Maybe the cpp file needs it?
