# 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.
