Doc Date 2025-06-19 Mailing Date 2025-07 Post-Sofia Author(s) Mateusz Pusz, Dominik Berner, Johel Ernesto Guerrero Peña, Charles Hogg, Nicolas Holthaus, Roth Michaels, Vincent Reverdy Target Audience LEWG SG6 SG16 SG18 Revisions R9 R8 R7 Tracking issue View on GitHub Abstract Several groups in the ISO C++ Committee reviewed the “P1935: A C++ Approach to Physical Units” [[P1935R2]](https://wg21.link/p1935r2) proposal in Belfast 2019 and Prague 2020. All those groups expressed interest in the potential standardization of such a library and encouraged further work. The authors also got valuable initial feedback that highly influenced the design of the V2 version of the [[
	P3104R4	Bit permutations	Jan Schultke J. Schultke	LWG SG6	2025-06-28	2025-07
Doc Date 2025-06-28 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience LWG SG6 Revisions R6 R5 Tracking issue View on GitHub Abstract Add bit permutation functions to the bit manipulation library.
	P3348R4	C++26 should refer to C23 not C17	Jonathan Wakely J. Wakely	LWG SG6	2025-06-19	2025-07
Doc Date 2025-06-19 Mailing Date 2025-07 Post-Sofia Author(s) Jonathan Wakely Target Audience LWG SG6 Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract There is a new version of the ISO C standard, so we should update our normative reference, and update the header synopses in the library clauses to match the content of the C standard library. A similar change to rebase C++17 on C11 was previously done via [P0063R3: C++17 should refer to C11 instead of C99](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0063r3.html) (see R0 for more det
	P3642R1	Carry-less product: std::clmul	Jan Schultke J. Schultke	SG6 SG18	2025-06-03	2025-07
Doc Date 2025-06-03 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience SG6 SG18 Revisions R7 R6 R5 R4 R2 Tracking issue View on GitHub Abstract Add widening and non-widening carry-less multiplication functions.
	P3647R0	Slides for P3642R1	Jan Schultke J. Schultke	SG6 SG18	2025-06-19	2025-07
Doc Date 2025-06-19 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience SG6 SG18 Revisions R1 Tracking issue View on GitHub Abstract Intuition: "carry-less" means we use XOR instead of plus.
	P3724R0	Integer division	Jan Schultke J. Schultke	LEWG SG6	2025-06-06	2025-07
Doc Date 2025-06-06 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience LEWG SG6 Revisions R4 R3 Tracking issue View on GitHub Abstract C++ currently only offers truncating integer division in the form of the `/` operator. I propose standard library functions for computing quotients and remainders with other rounding modes.
	P3764R0	A utility function for propagating the most significant bit	Jan Schultke J. Schultke	SG6	2025-07-15	2025-07
Doc Date 2025-07-15 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience SG6 Tracking issue View on GitHub Abstract Add a function to the `<bit>` header which converts the most significant bit to a bit mask.
	P3772R0	std::simd overloads for bit permutations	Jan Schultke J. Schultke	SG6	2025-06-28	2025-07
Doc Date 2025-06-28 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience SG6 Revisions R2 Tracking issue View on GitHub Abstract [[P3104R3]](https://wg21%2elink/p3104r3) has been been design-approved by LEWG for C++29. This proposal adds `std::simd` overloads to add consistency with [[P2933R4]](https://wg21%2elink/p2933r4).
	P3788R0	Fixing `std::complex` binary operators	Mateusz Pusz M. Pusz	LEWG SG6	2025-07-11	2025-07
Doc Date 2025-07-11 Mailing Date 2025-07 Post-Sofia Author(s) Mateusz Pusz Target Audience LEWG SG6 Tracking issue View on GitHub Abstract This paper proposes a backward-compatible solution to fix the inconsistent behavior of `std::complex` binary operators with implicit conversions. The proposed changes:
	P3793R0	Better shifting	Brian Bi B. Bi , Jan Schultke J. Schultke	SG6	2025-07-15	2025-07
Doc Date 2025-07-15 Mailing Date 2025-07 Post-Sofia Author(s) Brian Bi, Jan Schultke Target Audience SG6 Revisions R2 Tracking issue View on GitHub Abstract We propose the addition of functions to the `<bit>` header to perform bit shifts on integer operands. The `std::shl` and `std::shr` functions provide the following advantages over the built-in shift operators:
