Hi Siu Kwan Lam,

that looks very interesting! It is very nice to see how easy it is to 
install and how easy it is to add proper function annotations. Also, the 
generated source code seems to be a good start. It would be interesting 
to try it with Polly [1]. I believe that this could give great speedups 
for the naive matrix multiply implementation.
Is there a way I can dump the content of the entire LLVM-IR module 
generated in the demo/matrixmul/matrixmul.py example?

Cheers
Tobi
