I have been doing some modification work on fasttrap provider in Dtrace. i
have made some modifcation to make it work for function usage list.
for example dtrace -n pid$target:test::return{@func[probefunc]=count();}' -c
./test, will list all functions with number of times each function is
called.
Also if a function had more than one return path dtrace would give a Pread()
Fail error and the probe for the function would fail.
The attached patches solved the problem for me.
