commit r16-6001-ge2026d74f61c4883d7ac834773ed9dca6d9cc30a Author: Luc Grosheintz <[email protected]> Date: Mon Dec 8 21:23:46 2025 +0100 libstdc++: Set __cpp_lib_submdspan to 202411. The submdspan feature is complete and this commit sets the feature testing macros accordingly. Also makes the feature testing macro submdspan depend on constant_wrapper. Also changes the value of the internal feature testing macro for padded layouts to 202403. libstdc++-v3/ChangeLog: * include/bits/version.def (padded_layouts): Set to 202403. (submdspan): Set to 202411 add dependency. * include/bits/version.h: Regenerate.
