On linux we have Kernel Code Coverage Analysis where in we can measure
how much of the kernel code is run during a test. GCC provides the code
coverage at user level program if program is compiled with certain
flags. On a similar basis can we get Code coverage for the kernel on
Mac.
I don't know that we have any tools that have been used for code
coverage. What tools do you use to get code coverage data for the
linux kernel?
There is a patch that allows kernel to be compiled with -fprofile-arcs and -ftest-coverage. gcov input data (.bb files) are dynamically exported in /proc file system.
