--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Not a bug, see PR 79973 which talks about constant folding vs runtime
implementation of atanh but the same applies to cos here.
a 1ulp difference is very much acceptable difference really.
Note clang/LLVM incorrectly rejects the code if change to use constexpr instead
of const and -std=c++26 (std::cos in C++26 is required to be constexpr).
*** This bug has been marked as a duplicate of bug 79973 ***
