--- Comment #10 from Filip Kastl <pheeck at gcc dot gnu.org> --- So the call to 'cleanup_tree_cfg ()' in 'tree-profile.cc:tree_profiling ()' removes __gcov3 from GIMPLE. Then eventually 'symtab->remove_unreachable_nodes ()' in 'ipa_passes ()' removes __gcov3 from the symbol table. But then 'ipa_passes ()' calls 'coverage_finish ()' which adds __gcov3 back into the symbol table. That doesn't seem right. Why add __gcov3 into the symbol table when it isn't referenced in the IL anymore.
