For now, I would stick to `is_contiguous` for the input iterators as well. However, as we discussed, we can (and should) introduce a notion of a "self-contained" iterator in a future patch. Once we have that, `iota_view` and others can specialize that libc++-internal trait and we can run those on the GPU as well. https://github.com/llvm/llvm-project/pull/66968 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
