--- Comment #16 from Martin Liška <marxin at gcc dot gnu.org> --- > For our application, all processes generating profiling feedback data to a > single directory seems is not a choice. Why is it problem? You need to provide reasoning for that. > We chose -fprofile-dir=%p and then use gcov-merge to merge them. Sure, that's possible but you pay with a lot of disk space needed. Btw. how long does it take to merge all the collected data with gcov-tool?
