There are something like 10^6000 possible kernel configurations though, so no promises (regardless of toolchain). https://www.kernel.org/doc/html/latest/kbuild/llvm.html#supported-architectures https://www.kernel.org/doc/html/latest/kbuild/llvm.html#supp... We support clang-11 and newer. Linus Torvalds has been using clang to build the kernels he runs personally, for ~2 years now. https://lore.kernel.org/lkml/CAHk-=wiN1ujyVTgyt1GuZiyWAPfpLwwg-FY1V-J56saMyiA1Lg@mail.gmail.com/ https://lore.kernel.org/lkml/CAHk-=wiN1ujyVTgyt1GuZiyWAPfpLw... >> I build the kernel I actually _use_ with clang, and make sure it's clean in sane configurations Not sure what's going on these days in Android land, thankfully no longer a problem of mine.
