RE: Any docs about gcov impl change from 3.3 to 3.4

["Fei, Fei" <fei dot fei at intel dot com>]

What I am doing is to apply coverage test for xen project
(http://www.cl.cam.ac.uk/Research/SRG/netos/xen/), exp for hyperviser.
It's like the GCOV/LCOV thing which IBM did for Linux kernel but should
be different in hypervisor case. I will base on GCC 3.4 or above. So I
need to know some low level knowledge gcov.

I have read the OLS document which IBM present on Linux Symposium. But
it seems it only cover GCC 3.3.

Also I want to have some document about format of foo.gcda and for.gcno
files.
