--- Comment #9 from Martin Liška <marxin at gcc dot gnu.org> ---
Tom, known as a DejaGNU expert, would it be possible to add a test that will
check that following grep is empty:

./xgcc -B. --help=param | grep -v 'as parameters:' | grep '[^\.]$'
  hot-bb-count-fraction       Select fraction of the maximal count of
repetitions of basic block in program given basic block needs to have to be
considered hot (used in non-LTO mode)

Thanks
