[libcxx-commits] [PATCH] D60880: [libc++] Use COPYFILE_CLONE from the macOS copyfile(3) API to support APFS clones

[Adrian Prantl via Phabricator via libcxx-commits]

aprantl added a comment.

I found one more quirks while debugging why https://reviews.llvm.org/D60802 caused a clang modules crash reproducer test to fail:

COPYFILE_DATA will succeed if the destination file already exists, whereas COPYFILE_CLONE returns EEXIST.
