# gcov capability for udev
#
# Provides code coverage analysis for udev.
#
# make_gcov.sh assumes the same same default parameters as make, but also
# accepts the same parameters as make (see README file in udev/ for
# parameter info).  There is one exception, klibc can not be used with
# gcov as it will not compile cleanly.
#
# make_gcov.sh then overrides CFLAGS to strip out optimization in order
# for gcov to get correct code coverage analysis.
