I'm trying to compile kernel module by Clang, note that
the kernel is compiled by GCC.
(I know that there have some problem to compile kernel without any patches,
that's why I only want to compile kernel module here, not kernel)
As we known, Clang/llvm doesn't support global register variable at present,
when the kernel module C file include <linux/module.h>, it report that error,
register unsigned long current_stack_pointer asm("esp") __used;
so is there have any workaround to handle this problem? I just want to compile
kernel module only by Clang. Thanks.
