Hi Tobias, thanks for the answer. I'll try to give a look to the code you pointed me to , and I'll try to make the modification myself. I'm new to LLVM and Polly, but the code of both seem clean and understandable, so I hope to be able to do it myself. In case I'll ask here for support :) Marcello 2011/10/1 Tobias Grosser <tobias at grosser.es>: > On 10/01/2011 03:26
