Late to the conversation sorry.
I think this sounds like a good plan. Given we are planning to stick with a vanilla LLVM but just fix the version, it seems it should make it reasonable to have distro’s support this. We can provide binaries easily, but also just a declaration that llvm-3.4 is the current supported version, so please package that and tell GHC where to find it.
Agreed.
We already do this in a weak way by checking which version of LLVM the user is using and issuing a warning when it’s one we don’t support.
The other aspect that would be very useful is if all the build machines tested with LLVM as well. It’s a lot of work to support LLVM across all the platforms we support and to track changes across both communities. Automated testing of the currently supported LLVM version and LLVM-HEAD would be great.
Absolutely, this would be amazing. I generally don't find out about regressions due to LLVM until I have time to build and test a snapshot which doesn't happen nearly as often as I would like. Cheers, - Ben
