llvmpy = JIT python via llvm keynotes

• llvmpy
• a jit python interpreter via llvm
• a  wrapper interface between llvm c/c++ function calls and python interface
• flow
• wrapper c/c++ code to shared lib, such as pass, target, VM...
• explore the shared lib to python import path
• import it
• example
original c/c++ code

#include "dpi.h"

/* c_add */
int
c_add(int a, int b) {
  return a+b;
}

wrapper it via c/c++ python extend

#include <Python/Python.h>
#include <numpy/arrayobject.h>
#include <stdio.h>
#include <stdlib.h>
#include "dpi.h"

/* wrapper add, ref count definition */
static PyObject *
dpi_add_wrapper(PyObject *self, PyObject *args)
{
  int a, b, c;

  // parse arguments
  if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
    return NULL;
  }

  // run the actual function
  c = c_add(a, b);

  // build the result to a Python object.
  return Py_BuildValue("i", c);
}

/* register methods */
static PyMethodDef DPIMethods[] =
{
      {"dpi_add", dpi_add_wrapper, METH_VARARGS, "Calculate the sum of two integers."},
      {NULL, NULL, 0, NULL}
};

register to python search path

from distutils.core import setup, Extension


# ref : http://docs.python.org/2/extending/building.html
# the c++ extension module
extension_mod = Extension("dpi", ["moduledpi.c", "dpi.c"], include_dirs=['/var/root/anaconda/lib/python2.7/site-packages/numpy/core/include'],

setup(name = "dpi", ext_modules=[extension_mod])

run it

>>> python
>>> import dpi
>>> dpi.dpi_add(1,2)
