--- 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 gazillion 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?
