/* This program's "test for excess errors" demonstrates that combining
   the target options -mcpu=power9 and -mno-power9-vector does not
   result in an error.  A previous version of the compiler aborted
   with the error message:

      "power9-dform requires power9-vector."

   when these two options were used in combination.

   The newer version of the compiler, instead, automatically disables
   power9-dform when the -mno-power9-vector command-line option is
   specified.  */
