My First Superoptimizer

• souper

  12 2,073 3.4 C++

  A superoptimizer for LLVM IR

  

If anyone's interested in non-toy usage, there's the souper project as well https://github.com/google/souper

It's a shame it's a bit hard to actually build these days. Its target is people working on compilers, not end users. But there are some odd cases where I'd really like to use it myself, like trying to get speedup in llama.cpp.

  Basic SAT model of x86 instructions using Z3, autogenerated from Intel docs

Better than brute force is using a model of your instruction set (x86 start here [1]), then using something like Z3 [] to find solutions. Here's a paper doing the same [2]. With these approaches you can get vastly bigger pieces of code generated than brute force, and with significantly less hand heuristic tuning effort (which likely still loses out to current solvers).
