Let's Write an LLVM Specializer for Python (2015)

• pulse7 7y ago
  Nice, compressed LLVM overview...
• saagarjha 7y ago
  Cool! Aside from the Python JIT portion, this was a pretty decent dive into LLVM. One question: was this a notebook, or it it just CSS that's making the code look like that?

    It's this Jupyter notebook: https://github.com/sdiehl/numpile/blob/master/Let's%20Write%20an%20LLVM%20Specializer%20for%20Python!%20(Stephen%20Diehl).ipynb https://github.com/sdiehl/numpile/blob/master/Let's%20Write%...

    Whoa, I've had this idea kicking around in my mind for a looong time (specifically something for dynamically generating Go code). Was wondering if anyone actually built this out, but could never find anything. Thanks for sharing!

  I recommand David Beazley's talk from a recent PyCon India on a similar subject : https://youtu.be/r-A78RgMhZU https://youtu.be/r-A78RgMhZU Mostly live coded, it really is pretty amazing but also quite insightful.

    > In this talk, I live-code a simple stack machine and turn it into an interpreter capable of running Web Assembly. I then use that to play a game written in Rust. Wow. This is mind blowing. Thanks for the pointer.

      He has a lambda calculus talk in python[0] that is just as good. Just a great educator. [0] https://www.youtube.com/watch?v=pkCLMl0e_0k https://www.youtube.com/watch?v=pkCLMl0e_0k

        U of Chicago, I believe, denied him tenure, when he was an assistant prof there.

          How good of an educator you are may not even be in the top 5 most important things to get tenure, unfortunately.

  Anyone got a benchmark for the LLVM'd code?

  Why not just use Nim?
  • nurettin 7y ago
    Use nim to create an LLVM specializer for python and call numpy functions with it?
  • sigzero 7y ago
    I like Nim. I am learning it now. However, Nim is not Python and this post is about Python.

  I'm wonder why llvmpy depends on llvm3.2 or 3.3, it's so a lot behind current version.
  • hsaliak 7y ago
    The article is from 2015. Many of the jits (eg numba) have moved to llvmlite. https://github.com/numba/llvmlite https://github.com/numba/llvmlite
• accnumnplus1 7y ago
  Am I being daft, or is there not much sbout specializers on the web? Any links much appreciated.
• gjvc 7y ago
  As others have noted, this is a somewhat dated article. Indeed, the github page for llvmpy (https://github.com/llvmpy/llvmpy https://github.com/llvmpy/llvmpy) recommends to use llvmlite (https://github.com/numba/llvmlite https://github.com/numba/llvmlite) instead. See also http://llvmlite.pydata.org/en/latest/user-guide/index.html http://llvmlite.pydata.org/en/latest/user-guide/index.html and in the context of the original article, in particular these two pages: http://llvmlite.pydata.org/en/latest/user-guide/ir/examples.html http://llvmlite.pydata.org/en/latest/user-guide/ir/examples.... http://llvmlite.pydata.org/en/latest/user-guide/binding/examples.html http://llvmlite.pydata.org/en/latest/user-guide/binding/exam... Hope this helps! :-)
