gcov question

[Mariana Solaro]

Hello, I have a question about gcov an how to use it.
We are using the sparc ERC32 processor, and the RTEMS 4.10 version.
We've seen that there is a tool called gcov that allows it to measure 
the tests coverage. We don´t know exactly how to use it with RTEMS. We 
already try to compile the source code with the -ftest-coverage and 
-fprofile-arcs options, but it only generates the .gcno files, and not 
the .gcda files, so when using gcov, the coverage indicated is 0%.
When the linker starts it says that it can't find the __gcov_init and 
__gcov_merge_add functions.
So, I would like to know how to use the gcov and gprof tools with RTEMS 
if it is posible.

Thank You!

Bye
