I'm trying to use gcov to get the coverage information

I compile gcc source code (after I type in the command

testsuite yet!

You need to give us more info. What commands you typed, what output you got, and why you think this output is wrong.

If particular, you need to explain what you mean when you say that there was already coverage info there.

Can anybody tell me what's wrong and how to get rid of
those coverage info before I start to run testsuite?

You get rid of coverage info by deleting the files that contain it. Deleting the .gcda files should do. However, I am skeptical that there are any .gcda files there. (In older gcc versions, these would be .da files.)

If you have already run the testsuite, then there will be some coverage info generated because the testsuite tests gcov. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
