It would be nice having a test-case that can test your approach.
The problem is that you need the linker set to get access to the gcov
information. The test program of the commit message works on my Linux
machine. I am not sure if it is generic enough for the test suite.
Instead of printing the information we could compare it against an
expected output so that we have a self-contained test program.
Yep, that would be nice.
I tried to run the attached test case as
"gcc/testsuite/gcc.dg/gcov-info-to-gcda.c". However, I get this error:

Is it possible to do such kind of tests? I also have to link to -lgcov?
Ok, the linking is not the problem. If I declare __gcov_info_to_gcda()
locally, the test runs.
