# This simple script is used to gather compile time metrics. You can use
# it with make like this:
#
# $ make CXX=g++_metric.sh
#
commandline=$@
# find the target and save it to a variable
until [ -z "$1" ] # test all command line parameters
do
if [ "-o" = "$1" ]
then
shift
target=$1
break
fi
shift
done
#unfortunately, time only goes down to seconds, so do it by hand...
start=`date +%s%N`
g++ $commandline
retval=$?
# only echo the compile time if the call was successful
if [ $retval -eq 0 ]; then
stop=`date +%s%N`
let "total = (${stop}-${start})"
# convert to microseconds even though we will only use milliseconds in the
# graphs
let "total = ($total)/1000"
# add the path, relative to $ACE_ROOT, to the beginning of the object name
# so that it can be used to name the object when it's processed.
# Note that this line is commented so the output won't interfere with the
# preprocessor output, i.e., when used by the tao_idl compiler.
echo "//compile time: ${PWD#$ACE_ROOT/}/${target} $total"
