[pypy-dev] Translating code to LLVM

[Eric van Riet Paap]

Hello,

We not yet tested the LLVM on Windows, but I believe the files will be 
stored in the \temp\usession-* directories.
The current SVN head is not compatible with the current translate_pypy . 
I would suggest you stick with pypy0.7
for testing the basic functionality. I think it is also a good idea to 
run the unittests in pypy/translator/llvm/test first
to see if things work.

cheers
Eric
