I am very interested in these patches. Any chance you can take up the upstreaming process again?
Tim's patches look a lot more polished and are better in line with the initial ::simd code he contributed. I feel development should be continued on Tim's patches.

Marcin, let us know if you agree with the comment fix. I can then commit the patch, when it's ready.

Thanks Marcin for improving the commit message. We all seem to agree that this is the right correction. Hence, I feel this is ready to upstream from my side. As there have been quite some opinions, it would be great to hear if there are any open concerns that should be adressed or if others also feel this LGT(them). We especially still need feedback from @kristina!
Thank you @kristina for the review. I must admit I do not fully understand in which way this is broken, but the attached test case clearly shows there is some memory issue. My (limited) understanding is that Twine(Weight->getZExtValue()) will be destroyed at the end of line 175 which means that already in line 176 we may potentially reference invalid memory.
http://llvm.org/docs/ProgrammersManual.html#dss-twine has a similar example and explicitly warns of such uses:

Thank you guys for taking care of some of the cmake system. @Meinersbur, I am fine with renaming Polly modules according to LLVM conventions if this makes things more consistent.

This is a good idea.

Interesting. Any idea what is going wrong here?

If this was not clear. I am very OK with this change.
This is a straightforward, but very nice infrastructure change. Thank you both for pushing JSON support ahead in LLVM!

I used the std::any variant as an easy way to showcase how the bindings generator could be modified to do what we want (and also to show how an ideal interface could look like). I feel we should bring this up on the isl mailing list first to see what would be a good way to add this feature. We potentially could replace std::any with a simpler C++11 compatible solution:

This has become obsolete, after Philip Pfaffe committed a better variant of this feature.

You can commit this. It will just be covered in the next update.

Sorry guys. Alain just started to look into this last week and we wanted to get him up-to-speed before getting in touch with you. I should have helped to coordinate better. I asked Alain to discuss with you which / what patches are still needed.
I have a patched version of the generator (very hacky) on top of the isl bindings. Not sure if this (happens to) be the right one: https://github.com/tobig/isl/tree/polly-bindings-andrei
Right. I am busy today, but can do a normal update thursday afternoon. I will then also push the current generator to github.

Yes, raise we should raise the version. Also, please add a propoer commit message explaining what the underlying error was here. We should also make sure that this bug has been fixed in the latest ppcg, such that we do not re-import it again.

Also looks good from me except the minor changes. Please update the patch if you agree.

@ftynse, the source is referenced in the patch summary. If we commit such a patch to Polly, we must make we have your permission to contribute it under the LLVM license and obviously need to acknowledge the source. For now, I asked Lorenzo to push the code as RFC to allow others to see how it would be used. This already sparked a comment from Philip and will likely spark further discussions on how to extend the interface. Thanks for commenting.

Thank you Philip. This clearly looks a lot better than my patch. From my perspective this looks good after Michael's comments are addressed. Thanks a lot.
