Comment AI generated C compiler - not so great (Score 3, Insightful) 160
Apparently the performance of the code it produces is worse than gcc with all optimizations turned off. That's pathetic. And it is written in rust, so it can't bootstrap - And the size of it is on par with a hand-written C compiler - so no win there.
When I worked on compilers at IBM, our first bootstrap of C for x86 was a cause for celebration. A double bootstrap was a great "smoke test". But that was relatively easy. Passing the validation test suites were *way* harder - like 50x harder.
