As explained in the covering note to the previous patch, the fact that aarch64-sve-* is now used for multiple header files means that function_builder::add_overloaded_function now needs to use a global map to detect duplicated overload functions, instead of the member variable that it used previously.
Tested on aarch64-linux-gnu & pushed. Richard gcc/ PR target/112989 * config/aarch64/aarch64-sve-builtins.h (function_builder::m_overload_names): Replace with... * config/aarch64/aarch64-sve-builtins.cc (overload_names): ...this new global.
