That paper, and several ancillary papers, do an excellent job of setting out the main features of an extension to C++ which allows generic data parallel programming on arbitrary targets. However, it is inevitable that the programmer will want to make some use of target-specific intrinsics in orde
	P2964R2	Allowing user-defined types in std::simd	D. Towner, R. Arutyunyan	LEWG SG6
Intent Proposal Mailing Date 2026-02 Pre-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG SG6 Revisions R5 R4 R3 Tracking issue View on GitHub Abstract The C++ standard library includes data-parallel types in the `<simd>` header, currently restricting element types to a closed list: arithmetic types and `std::complex` specializations. This paper proposes a minimal change to the specification in which the closed list is replaced with trait-based constraints that handle all existing types while naturally extend support to enumerations, `std::byte`
