I wonder if assembler is going to make a come back :). I'm certainly seeing a lot of cool projects that make assembly more accessible, not to mention a lot of good guides on the web. As for myself, I've recently made Python ctypes bindings for GNU Lightning, which lets you write architecture agnostic RISC assembly, then JIT to native code on x86, ARM, etc. See https://github.com/cslarsen/lyn/ https://github.com/cslarsen/lyn/ It's pretty light-weight and JITs fast. The point is that it's very fun and addictive to do assembly from a language like Python.

  My biggest problem with assembly was coming up with names for all of the labels :) One of the hardest problems of CS... naming! How does PeachPY handle loops? I'm looking for examples, but will it generate a label for me and then let me specify the contents only? Edit: https://github.com/Maratyszcza/PeachPy/blob/master/examples/make/matmul-opt.py https://github.com/Maratyszcza/PeachPy/blob/master/examples/... ! (Add a bit more, give it some static typing and soon we'll be coding C in Python)

    That's how you unroll a loop, not how you write one. As far as I can tell in PeachPy you can do something similar with anonymous labels: counter = GeneralPurposeRegister64() MOV(counter, 64) with Loop() as loop: ... DEC(counter) JNZ(loop.begin)

      Thanks for the clarification, that's still a decent improvement.

I proposed a while back to replace inline assembler with inline LLVM bytecode. Do the portable code thing in general except accelerate the algorithms with the bytecode. Toolchain produces assembly from that. Probably still have real assembly where it's needed for hardware manipulation, etc but I'd think you'd get quite the performance/optimization improvement with that over C. What you think about LLVM as cross-platform assembly?
