This was reverted because it was breaking when targeting Darwin which tried to export these symbols which are now hidden. It should be safe to just stop attempting to export these symbols in the clang driver, though Apple folks will need to change their TAPI allow list described in the commit where these symbols were originally exported https://github.com/llvm/llvm-project/commit/f5380185623be243ba0f1b18d4bd594ac5cc7163 Then reverted again because it broke tests on MacOS, they should be fixed now. Bug: https://github.com/llvm/llvm-project/issues/58265 Differential Revision: https://reviews.llvm.org/D135340
