Is there any self-improving compiler around?

I am not aware of any self-improving compiler, but then again I am not much of a compiler-guy.

Is there ANY self-improving compiler out there?

Please note that I am talking about a compiler that improves itself - not a compiler that improves the code it compiles.

Any pointers appreciated!

Side-note: in case you're wondering why I am asking have a look at this post. Even if I agree with most of the arguments I am not too sure about the following:

We have programs that can improve their code without human input now — they’re called compilers.

... hence my question.

A self improving compiler would, by definition, have to have self modifying code. If you look around, you can find examples of people doing this (self modifying code). However, it's very uncommon to see - especially on projects as large and complex as a compiler. And it's uncommon for the very good reason that it's ridiculously hard (ie, close to impossible) to guarantee correct functionality. A lot of coders who think they're smart (especially Assembly coders) play around with this at one point or another. The ones who actually are smart mostly move out of this phase. ;)
