[libcxx-commits] [PATCH] D112126: [libunwind] Try to add -unwindlib=none while configuring and building libunwind

[Martin Storsjö via Phabricator via libcxx-commits]

mstorsjo added a comment.

Factorized the tricky testing of `--unwindlib=none` to a separate cmake function, use this for the other similar-ish linker flags too.

I tried to mimic the naming and behaviour of the `check_c_compiler_flag` function, but should it be named more distinctly away from conflicting with possible future cmake core functions? And we could have the function append the tested flag directly to `CMAKE_REQUIRED_FLAGS` if succeeded too, instead of letting the caller do it.
