--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
See e.g. PR72785, using __builtin_constant_p this way isn't really going to
work reliably, it is folded too late and jump threading and other optimizations
may cause it to be evaluated to 1 in some part of a function and 0 in another.
