--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- A few are handled here: https://gcc.gnu.org/pipermail/gcc-patches/2024-November/669746.html https://gcc.gnu.org/pipermail/gcc-patches/2024-November/669747.html There are at a few more which uses aarch64_get_attributes with a default value of nullptr. I am still deciding if the default should just be leaf or not. Or always require an attribute argument. The same can be said of aarch64_general_simulate_builtin .
