Hi,
Gcc is now working on aarch64 but the kernel does not compile because of some idiomatic clang code that is not supported by gcc (at least gcc-6) To define constants, it uses: static const uintmax_t FOO = __BIT(9), BAR = FOO; While this is nice, specially for the debugger, it produces an error in gcc. While fixing these is easy, gcc also complains about using the constants as switch labels. Thus it is better to just nukem all and rewrite them as: #define FOO __BIT(9) #define BAR FOO Should I go ahead and do it, or there is a smarter solution? christos
