> I just think it's a potentially awkward situation when it comes to something as core as the kernel; which has traditionally only required GCC. Clang is starting to leapfrog GCC here. IIRC, some features are better supported and/or more advanced on Clang, other features (e.g. LTO) are exclusive to it. Not to mention it's almost a certainty for Clang to land kernel PGO support long before GCC, in fact Google already uses it in production Android kernels. Anyway, rust or not, linux is being decoupled from GCC.
