--- Comment #3 from qinzhao at gcc dot gnu.org --- (In reply to Martin Liška from comment #2) > Thank you for the report. It's a known limitation Honza noticed me about. > Is the size problematic from size perspective or speed perspective? I think both size and speed. for the full execution of our application, the GCC's profiling data is too big to out of the disk space. at the same time, since we have to merge all the profiling data for different processes, the merging process take a long time due to so many profiling data files. > Have you tried compressing the gcda files? > > Anyway, I'm going to work on that this stage1. thanks a lot. this is a high priority task for us.
