--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Of course, another bug is that the declaration of aarch64_simd_types isn't =
GTY

 #endif
which means it is then ignored on the definition as well.
But with the above 2 patches it fails to build because it then tries to inc=

aarch64_simd_types references in gtype-desc.cc but doesn't include there th=
