If it helps, we will see how to proceed ;)Well, after grepping LLVM source for apparent lack of it and googling for couple of apps which didn't bootstrap, I proceeded to write mine either as a learning exercise, but I'm still not sure I do it the best way or handle all cases (so far testing on trivial examples of course), so if your app in open source, definitely would be nice to look at. What I have on my hands so far: http://postimage.org/image/j4opcf4xf/> Cheers, > Sebastian-- Best regards, Paul mailto:pmiscml at gmail.com

Anyway, I'm going to wrap things up (needs roughly a day) and then provide it via GitHub. I'm going to send another mail with the projects link.

I'm going to send another mail with the projects link. >You can get the source from https://github.com/sdressler/KernelDataFlow There are some flaws in the code: - assert is not always used as it is intended to be, i.e. mostly its within an if-statement and simply performs "assert(0)" with a preceding error message. - It can happen that not all instructions are handled. In such a case you could extend it yourself or write me an email with the code that fails. - If you are calling the pass from another directory than the one with the source, don't forget to "mkdir graphs", otherwise subgraphs (which are related to blocks) will not be generated. If there are any further questions, don't hesitate to write me. The pass is at a very early stage, but hopefully it gets some more quality when someone else uses it.
