--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #5) > There is no ullabs in C++ yet (maybe C++26 will pull in ullabs from C23). ullabs is C26 not C23, so won't be in C++26. The proposal to add it to C was from 2024: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3349.pdf
