# Library of functions for dealing with DejaGNU, or which are otherwise # generally useful for the DejaGNU tool stack. # # Author: Matthew Sachs <msachs@apple.com> # # Functions: # parseLogFile: See "sub parseLogFile" below for details. This function # returns a detailed parse of a DejaGNU log or sum file. # ispass: Takes a DejaGNU result (e.g. "PASS", "XPASS") and returns # true if and only if it is a passing result (PASS, XFAIL, or # KFAIL.) # # Copyright (c) 2006 Free Software Foundation. # # This file is part of GCC. # # GCC is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # GCC is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
