--- 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
