Hi I created a simple native example to see what options work for gcov and sub-expressions. Hopefully I got the simple method and test main right.
"make clean all" will compile, execute, and run gcov. Edit the Makefile to change arguments. Edit program.c to change test cases. Three test cases for 100% coverage. Comment some out to see the impact. Hopefully we can see what we need to do or the limits. --joel
