So I'd recommend to Sami to simply make the Kconfig also depend on
clang's integrated assembler (not just llvm-nm and llvm-ar).

Sure, sounds good to me. What's the preferred way to test for this in Kconfig?

It looks like actually trying to test if we have an LLVM assembler
(e.g. using $(as-instr,.section
".linker-options","e",@llvm_linker_options)) doesn't work as Kconfig
doesn't pass -no-integrated-as to clang here. I could do something
simple like $(success,echo $(LLVM) $(LLVM_IAS) | grep -q "1 1").

Thoughts?

Sami

I think

    depends on $(success,test $(LLVM_IAS) -eq 1)

should work, at least according to my brief test.

Cheers,
Nathan
