[PATCH] D109128: [VFS] Use original path when falling back to external FS

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai added a comment.

Was looking at an issue caused by over-eager RedirectingFileSystem path canonicalization and this patch fixes it. The repro we have is more complicated (involves 3 modules), so I don't think it is worth including with this change.



================
Comment at: llvm/lib/Support/VirtualFileSystem.cpp:2006
 ErrorOr<std::unique_ptr<File>>
 RedirectingFileSystem::openFileForRead(const Twine &Path_) {
   SmallString<256> Path;

Another idea is to keep this variable `Path` and rename old Path to `CanonicalPath`.
