But there's a slight difference to traditional mtune behaviour: in this case there are calls to external routines inserted, not just some slight preferences in using (say) shl x,1 vs. an add x,x instructions. That makes sense indeed, it's a bit different.

GCC 10.1 will enbale '-moutline-atomics' by default. So we don't need to explicitly enable the flag, and I don't need to patch Clang to ignore it, right?
