    { dg-options "-mzarch -save-temps" }

   Note that dejagnu-1.5.1 has a bug so that the action from the second dg-do
   always wins, even if the condition is false.  If this test is run on hardware
   older than z10 with a buggy dejagnu release, the execution part will fail.

    { dg-do assemble }
    { dg-do run { target { s390_useable_hw } } }

   Skip test if -O0, -march=z900, -march=z9-109 or -march=z9-ec is present on
   the command line:

    { dg-skip-if "" { *-*-* } { "-march=z9*" "-O0" } { "" } }

   Skip test if the -O or the -march= option is missing from the command line
   because it's difficult to detect the default:

    { dg-skip-if "" { *-*-* } { "*" } { "-O*" } }
    { dg-skip-if "" { *-*-* } { "*" } { "-march=*" } }
