Silica: Testing Every AArch64 Instruction Encoding

I wanted to see what happens when you compare real AArch64 decoders across the entire 32-bit encoding space, so I built Silica.

It checks all 4.3B encodings against Arm's spec, LLVM, Capstone, and Unicorn. I'm still digging through some of the stranger disagreements.
