Hi Sean, I had to add ‘v16f16’ to our out-of-tree target, and this was to primarily to allow me to express lowering for all the OpenCL types (well, except for the ‘v3T’ types). The trend does seem to be towards larger bit-width SIMD registers, and as you say this will increase in time; but perhaps instead of using a discrete enumeration combined with additional entries in several switch-statements, it might be better to rethink MVTs using templates so that th...

Hi, Our backend for Pixel Visual Core uses some MVT's that aren't upstream. Does it make sense to upstream them? I figure that as architectures get wider, we'll eventually have "all" possible combinations of widths and types, but on the other hand having code that isn't used by current backends in tree isn't great. These are the MVT's that we have added: 16x16
