[PATCH] D21113: Add support for case-insensitive header lookup

[Peter Collingbourne via Phabricator via cfe-commits]

pcc added inline comments.


================
Comment at: lib/Basic/VirtualFileSystem.cpp:483
+CaseInsensitiveFileSystem::openFileForRead(const Twine &Path) {
+  SmallVector<char, 512> NewPath;
+  if (std::error_code EC = findCaseInsensitivePath(Path.str(), NewPath))
----------------
I wonder whether it would help with performance to try the original path here first, then do the case insensitive stuff only if that failed.
