--- Comment #18 from sandra at gcc dot gnu.org ---
I'm seeing the missing gcov file on nios2-linux-gnu as well.  Git revision
6e00d8dcf32ace6588a1a4843dfcc0e8b9f9d00f.

I took another look at the testcase.  I haven't used gcov for about a gazil=
lion
years, but...

It says "{ dg-do compile }".  Don't you have to run the testcase to collect=
 the
data to run with gcov?  And copy the .gcda file from the target to the host?

Then, it is trying to run "gcov gcov-pr94029.c" instead of e.g. "nios2-elf-=
gcov
gcov-pr94029.c", and it's picking up some random gcov program installed on =
the
host system instead of the one for the target.

Maybe this testcase should just be restricted to native targets?=
