#!/bin/sh # # 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. # # Leann Ogasawara <ogasawara@osdl.org>, April 2004 # clean up udev dir clean_udev () { find -name "*.gcno" -exec rm -f "{}" \; find -name "*.gcda" -exec rm -f "{}" \; find -name "*.gcov" -exec rm -f "{}" \; rm -f udev_gcov.txt make clean } PWD=`pwd` GCCINCDIR=`gcc -print-search-dirs | sed -ne "s/install: \(.*\)/\1include/gp"` LIBSYSFS="-I$PWD/libsysfs/sysfs -I$PWD/libsysfs" WARNINGS="-Wall -Wshadow -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations" GCC="-I$GCCINCDIR" USE_LOG="-DLOG" DEBUG="-D_GNU_SOURCE" GCOV_FLAGS="-pipe -fprofile-arcs -ftest-coverage" for i in $*; do pre=`echo $i | sed 's/=.*//g'` post=`echo $i | sed 's/.*=//g'` if [ $pre = "USE_KLIBC" ] && [ $post = "true" ]; then echo "cannot use gcov with klibc, will not compile" exit elif [ $pre = "USE_LOG" ] && [ $post = "false" ]; then USE_LOG="" elif [ $pre = "DEBUG" ] && [ $post = "true" ]; then DEBUG="-g -DDEBUG -D_GNU_SOURCE" elif [ $pre = "clean" ]; then clean_udev exit fi done clean_udev make $* CFLAGS="$WARNINGS $GCOV_FLAGS $USE_LOG $DEBUG $GCC $LIBSYSFS" LDFLAGS="-Wl,-warn-common -fprofile-arcs"
