--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
assume_aligned is something different, I guess __builtin_is_aligned expands to
an actual runtime check (perhaps optimized away if the pointer can't be
misaligned).
So I guess __builtin_is_aligned (__builtin_assume_aligned (ptr, 32), 16) should
optimize to true...
I guess I have big questions on what exactly will it do during constexpr
evaluation - if it is on a pointer to object with certain alignment, for
smaller alignment arguments guess it is just like pointer arithmetics then, but
if it asks for larger alignment, shall it make it non-constant expression?
