Jonathan Wakely f35da524a2 Adjust std::rotl, std::rotr etc to match final P0553R4 proposal ... This proposal has now been accepted for C++20, with a few changes. This patch adjusts std::rotl and std::rotr to match the final specification and declares the additions for C++2a mode even when __STRICT_ANSI__ is defined. * include/std/bit (__rotl, __rotr): Change second parameter from unsigned int to int and handle negative values. (rotl, rotr): Remove check for __STRICT_ANSI__. Change second parameter from unsigned int to int. Add nodiscard attribute. * testsuite/26_numerics/bit/bitops.rot/rotl.cc: Rename to ... * testsuite/26_numerics/bit/bit.rotate/rotl.cc: Here. Test negative shifts. * testsuite/26_numerics/bit/bitops.rot/rotr.cc: Rename to ... * testsuite/26_numerics/bit/bit.rotate/rotr.cc: Here. Test negative shifts.
