-Subject: [PATCH] [cmake] disable NEON runtime check on clang-cl
-
-When enabling runtime NEON checking for clang-cl, the linker would error out with `undefined symbol: __emit`, since clang doesn't actually implement this instruction. Therefore it makes sense to disable the runtime check by default on this platform, until either this is fixed or a clang-cl compatible intrinsic check is added (I don't have enough knowledge of MSVC to do this)
