[PATCH] D116659: [llvm][clang][vfs] NFC: Simplify directory iteration

[Jan Svoboda via Phabricator via cfe-commits]

jansvoboda11 added a comment.

I agree that introducing new iterator and implementing `iterator_range<...> FileSystem::dir_range()` is better solution than a macro.

I'm not sure the `dir_range` function needs to take an `std::error_code` out-param though. The error code is only used to stop the iteration, clients don't use it for any other purpose. I think the new iterator could handle error codes completely internally (by advancing to the end), providing better ergonomics. WDYT?

I might create a follow-up patches for //recursive// VFS-based iteration and also enable range-based for loops in code using `llvm::sys::fs` instead of the VFS.
