Hi, Is any effort being made to synchronize the upcoming MacRuby 0.7 release with the upcoming LLVM 2.8 release? How big are the changes to LLVM between the preferred MacRuby version (r106781) and the latest RC (https://llvm.org/svn/llvm-project/llvm/tags/RELEASE_28/rc2, r114689)? MacRuby HEAD doesn't build with 2.8rc2, (at a glance) related to the following changes listed here: http://llvm.org/docs/ReleaseNotes.html#whatsnew * LLVM 2.8 changes the internal order of operands in InvokeInst and CallInst. To be portable across releases, resort to CallSite and the high-level accessors, such as getCalledValue and setUnwindDest. * You can no longer pass use_iterators directly to cast<> (and similar), because these routines tend to perform costly dereference operations more than once. You have to dereference the iterators yourself and pass them in. I'm not expert on LLVM or MacRuby, but I'd like to see compatibility between 'stable' versions, so I'm happy to help if I can. Craig
