Technical Perspective: Building Bug-Free Compilers
What to do about buggy compilers? The authors of "Practical Verification of Peephole Optimizations with Alive" give us a compelling and practical answer.
From Communications of the ACM
Practical Verification of Peephole Optimizations with Alive
We created Alive, a domain-specific language for writing correct peephole optimizations and for automatically either proving them correct or else generating counterexamples...
