I meant code in C, not the produced machine code, so the size is not
really relevant.

I'm not sure how do you see that the code became more readable: we now
have AVOID where previously we had _Noreturn, and ATTRIBUTE_COLD where
we previously had nothing.  Both make the code slightly less readable,
IMO (because the reader must first learn what they mean).
