lol, had no idea what peephole optimizations were, but reading about them instantly brought back memories of reverse engineering byte code obfuscation as some 99% of the generated byte code is useless moving around of data that could be compacted into tighter representations. And yes, it consisted of a set of a large pattern matching rules that would be matched against windows of the code.
