Compyler is a pre-alpha x86 native code compiler. So far it can generate primitive .pyds but not standalone executables. It can run some simple test cases including pystones (although there is a memory leak there). And no, I don't expect it'll ever be much faster than Cpython <wink>. I was primarily interested in being able to distribute low-footprint standalone executables written in python and code obfustication. The basic approach taken by compyler is to transliterate python bytecode into x86 assembly, instead of trying to generate assembly from the syntax tree. This is basically abandonware. I haven't touched this in six months, but did do a lot of up front work. I basically wanted to release it before my hardrive blows up in case anyone was looking for prior art. The code also contains a version of pyasm that has some more patches and features than the official distribution if you're one of pyasm's 3 users.
