...IR. Would that spoil any other pass? What passes should run before/after such a pass? I believe that would be a FunctionPass and registered in the LoopDependencyAnalysis "runOnLoop()", so it can run when such pass is called by the PassManager. Or should it be a completely separate pass (VectorizationPass?) so we can control it from a separate command-line flag? Any comments appreciated before I dig in. cheers, --renato http://systemcall.org/ Reclaim your digital rights, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm

Ok. What's about Linux builds? Are there any other implementations e.g.

Hi Anton, Thanks a lot for offering help. Bullet uses basic linear algebra with 4-way vectors, quaternion and matrices. Although most of this is plain portable C++ perhaps LLVM can auto-vectorize some of this? There is a little bit of hand optimized x86 SSE code. This is only enabled on 32bit Windows and Mac OSX Intel builds. >> Should I just use the 2.75 release? If you are interested,
