Yes, those 3 test cases all suffer from "empty translation unit" problem. My patch just has an side effect which avoid "empty translation unit" problem. But the real problem is still there. pr92398.p9+.c has another problem. It's a compiling case and it should be compiled on any platform when "-mdejagnu-cpu=power9" is set in dg-options or RUNTESTFLAGS. Putting dg-options before "has_arch_pwr9" check achieves this target.
