I believe s390 kernel had limited clang build support since about 5.2 (with jump labels and ftrace disabled), thanks to contributions from Arnd Bergmann. With asm goto support in clang 9 and now everything for ftrace in place in clang 10 s390 kernel should be in a good shape feature wise (including KASAN). At this stage clang based tooling is the main interest.
