Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|ASSIGNED |RESOLVED --- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Fixed. Tried strcat etc., but there is: if (gimple_call_builtin_p (stmt, BUILT_IN_NORMAL)) check_builtin (stmt); which ensures strcat etc. calls make it through to check_strcat etc. only if they have the right number of arguments.
