[libcxx-commits] [PATCH] D142957: [CMake][runtimes] Redo the --unwindlib=none and -nostdlib++ checks

[Petr Hosek via Phabricator via libcxx-commits]

phosek added inline comments.


================
Comment at: runtimes/CMakeLists.txt:112-113
   # --unwindlib=none is supported, and use that if possible.
   # Don't add this if not necessary to fix linking, as it can break using
   # e.g. ASAN/TSAN.

----------------
@mstorsjo do you know what's the reasoning behind this? I was wondering if we could add `--unwindlib=none` and `-nostdlib++` unconditionally to simplify this logic and make the behavior more deterministic.
