Compiling X to C and then C to assembly is not more complex that compiling X straight to assembly. In your orignal comment you wrote that the complexity of such setup is bigger, to which I responded: no, not really.

Yes, C was not designed to be intermediate compilation step and this yields losses of some information (e.g. debugging metadata, but also some semantics of source language may get lost). I never argued with that. I never said that this is a perfect setup that doesn't introduce any new problems. I just said that compiling to C is very close to what is actually happening inside the compiler targeting assembly from higher level language.
