Hi!

Like for x86-64, alpha or rs6000, visium 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.

2024-03-20  Jakub Jelinek  <jakub@redhat.com>

	PR target/114175
	* config/visium/visium.cc (visium_setup_incoming_varargs): Only skip
	TARGET_FUNCTION_ARG_ADVANCE for TYPE_NO_NAMED_ARGS_STDARG_P functions
	if arg.type is NULL.

No gdbsim, so no execution results.  Builds fine though.
