Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG Revisions R4 R2 Tracking issue View on GitHub Abstract ISO/IEC 19570:2018 introduced data-parallel types to the C++ Extensions for Parallelism TS [P1928R15]. 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
	P2964R3	Allowing user-defined types in std::simd	D. Towner, R. Arutyunyan	LEWG SG6
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG SG6 Revisions R5 R4 R2 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`
	P3787R2	Adjoints to "Enabling list-initialization for algorithms": uninitialized_fill	G. D'Angelo, R. Arutyunyan	LEWG LWG
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Giuseppe D'Angelo, Ruslan Arutyunyan Target Audience LEWG LWG Revisions R1 Tracking issue View on GitHub Disposition Date 2026-03Adopted Abstract In the Tokyo 2024 meeting [P2248R8] (Enabling list-initialization for algorithms) was adopted.
	P3983R1	simd object representation	D. Towner, R. Arutyunyan	LEWG LWG SG1
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG LWG SG1 Revisions R2 R0 Tracking issue View on GitHub Abstract The Working Draft makes `simd` types trivially copyable types, which allows `std::bit_cast` operations. However, the object representation is unspecified, making the results implementation-defined.
	P4031R1	Rename system_context_replaceability namespace	R. Arutyunyan	LEWG
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Ruslan Arutyunyan Target Audience LEWG Revisions R0 Tracking issue View on GitHub Abstract This paper proposes to rename `system_context_replaceability` namespace.
