I’ve built a PoC binary optimizer called ASIC that replaces common instruction sequences with specialized instructions.

Even with only 2 patterns implemented out of 19 identified, it reduced a test binary by 0.02%. Imagine the potential once all patterns are covered.

Highlights:

Works directly on binaries, no source changes needed.

Compatible with existing optimizations like O2/O3, Oz, and strip.

Cross-architecture potential, not limited to ARM64 or ELF.

Can complement packing tools (like UPX) without slowing execution.

This is early-stage, but the concept proves instruction-level pattern replacement is feasible. Next step: implement all hot patterns for meaningful optimization.

Would love thoughts from anyone who’s worked with binary transformations or runtime instruction emulation.
