This 37# unittest tests that, by running low_level_alloc_unittest with an 38# LD_PRELOAD. (low_level_alloc_unittest was chosen because it doesn't 39# link in tcmalloc.) 40# 41# We assume all the .so files are in the same directory as both 42# addressmap_unittest and profiler1_unittest. The reason we need 43# profiler1_unittest is because it's instrumented to show the directory 44# it's "really" in when run without any args. In practice this will either 45# be BINDIR, or, when using libtool, BINDIR/.lib. 46 47# We expect BINDIR to be set in the environment. 48# If not, we set them to some reasonable values. 49BINDIR="${BINDIR:-.}" 50 51if [ "x$1" = "x-h" -o "x$1" = "x--help" ]; then 52 echo "USAGE: $0 [unittest dir]" 53 echo " By default, unittest_dir=$BINDIR" 54 exit 1 55fi 56 57UNITTEST_DIR=${1:-$BINDIR} 58 59# Figure out the "real" unittest directory.
