I tried this using the prebuilt binaries from apt.llvm.org:
$ make ARCH=hexagon LLVM=1 O=obj-hexagon CROSS_COMPILE=hexagon-linux- LLVM_IAS=1 CC=llvm-12 defconfig modules vmlinux <stdin>:1515:2: warning: syscall clone3 not implemented [-W#warnings] #warning syscall clone3 not implemented ^ 1 warning generated.
Doing the same thing with allmodconfig results in an internal error with clang-12 while compiling kernel/locking/lockdep.c. Same thing with clang-13. After turning off lock debugging, it seems fine.
