The GTY(()) has to come after an extern or static. The externs associated with the SVE ACLE GTY variables are in aarch64-sve-builtins.h. This file is not in tm_include_list because we don't want every target-facing file to include it. It therefore isn't in the list of GC header files either. In this case that's a blessing in disguise, since the variables belong to a namespace and gengtype doesn't understand namespaces. I think the fix is instead to add an extra extern before each variable declaration, similarly to varasm.cc and vtable-verify.cc. (This works due to a "using namespace" at the end of the file.) gcc/ PR target/106491 * config/aarch64/aarch64-sve-builtins.cc (scalar_types) (acle_vector_types, acle_svpattern, acle_svprfop): Add GTY markup to (new) extern declarations instead of to the main definition.=
