Hi!

Like for x86-64, alpha or rs6000, arc seems to be affected too.

Just visually checked differences in c23-stdarg-9.c assembly in a cross
without/with the patch, committed to trunk.

2024-03-19  Jakub Jelinek  <jakub@redhat.com>

	PR target/114175
	* config/arc/arc.cc (arc_setup_incoming_varargs): Only skip
	arc_function_arg_advance for TYPE_NO_NAMED_ARGS_STDARG_P functions
	if arg.type is NULL.
