================
Comment at: lld/MachO/DriverUtils.cpp:204
   CachedHashStringRef path(mbref.getBufferIdentifier());
-  DylibFile *file = loadedDylibs[path];
+  DylibFile *&file = loadedDylibs[path];
   if (file)

It's the canonical way to write a caching function. So my thinking was we need to have a comment about this so that nobody changes this to using a reference naively, and if we have to add the comment anyways we might as well take what the comment pays for. But I don't feel terribly strongly about it.
