Thank you for helping Jon. I'm still learning the llvm cross compiling
stuff, sometimes I might misunderstand it. I tried "make clang_linux" in
the compiler_rt directory, it would only build the "libcompiler_rt.a" for
x86_64, which is my host machine ISA. Could you please tell me how can I
build the arm version? I tried to modify the "make/platform/arm_linux.mk"
and "make/options.mk", but none of them work.
