--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
At -O0 that is a user error, the intrinsics have to be called with a compile
time constant and -O0 doesn't perform optimizations. That is e.g. why the
intrinsics that need that are at -O0 not defined as inline functions, but as
preprocessor macros. So, just pass to those constants rather than variables,
or say constexpr vars or something similar where you are guaranteed it is
evaluated to constant at compile time. Or compile with optimizations.
