You need a solution that also allows optimizations on > integer intrinsic functions (perhaps cast the vector type?). If you follow the links, you can find: https://gcc.gnu.org/ml/gcc-patches/2013-04/msg00374.html where I handled some integer vector intrinsics as well (there were some bugs in that patch, but the idea should be fine). > The proposed solution of using vector extensions will not work on masked > vector intrinsics in AVX512, so it wouldn't enable e.g. constant propagation > through a masked intrinsic, but that is probably too much to ask for :) I expect we can get most of the benefits from using vector extensions for very little effort, while handling the esoteric intrinsics would be a lot more work so it gets lower priority.
