The limitation > seem artificial at this point. Links to directories cannot be added with the current logic. Resolving paths and iterating directories becomes non trivial. Current implementation supports the use case of "file with multiple names" which is mostly sufficient to mimic the compilation. ================ Comment at: lib/Basic/VirtualFileSystem.cpp:529 +public: + InMemoryHardLink(Status Stat, InMemoryNode *ResolvedNode) + : InMemoryNode(std::move(Stat), IME_HARD_LINK), ---------------- ilya-biryukov wrote: > usaxena95 wrote: > > ilya-biryukov wrote: > > > ilya-biryukov wrote: > > > > Why do we need the Stat? > > > > We can get it from `ResolveNode` if we want to store a copy.

Since a raw pointer to the resolved file is returned by getResolvedNode (used by for lookup) , I have also changed some other raw pointer type to const pointer tpye.
