Hi, There is now an RFC for a roadmap to native vector predication support in LLVM and a prototype implementation:   https://reviews.llvm.org/D57504 The prototype demonstrates: -  Predicated vector intrinsics with an explicit mask and vector length parameter on IR level. -  First-class predicated SDNodes on ISel level. Mask and vector length are value operands. -  An incremental strategy

My first computer was a Mac (SE30) but it was also my last so I am not without appreciation of Apples wonderful aptitude for design. Without starting a flame-fest why do so many ruby and rails developers use a Mac ? It seems to be a commonality within the ruby and RoR community. Especially laptops. The first ruby users group meeting I attended was about 50% Macs (or so it seemed to me - I
