[PATCH] D30768: [PATCH][VFS] Ignore broken symlinks in the directory iterator.

[Juergen Ributzka via Phabricator via cfe-commits]

ributzka created this revision.

The VFS directory iterator and recursive directory iterator behave differently
from the LLVM counterparts. Once the VFS iterators hit a broken symlink they
immediately abort. The LLVM counterparts allow to recover from this issue by
clearing the error code and skipping to the next entry.

      

This change adds the same functionality to the VFS iterators. There should be
no change in current behavior in the current CLANG source base, because all
clients have loop exit conditions that also check the error code.
