--- Comment #16 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:e69456ff9a54ba3e9c93842b05757b7d8fff6d9d commit r15-2356-ge69456ff9a54ba3e9c93842b05757b7d8fff6d9d Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Jul 4 12:01:29 2024 +0100 libstdc++: Remove __find_if unrolling for random access iterators As the numbers in PR libstdc++/88545 show, the manual loop unrolling in std::__find_if doesn't actually help these days, and it prevents the compiler from auto-vectorizing. Remove the dispatching on iterator_category and just use the simple loop for all iterator categories. libstdc++-v3/ChangeLog: * include/bits/stl_algobase.h (__find_if): Remove overloads for dispatching on iterator_category. Do not unroll loop manually. * include/bits/stl_algo.h (__find_if_not): Remove iterator_category argument from __find_if call.
