Still same answer as before, i.e., it seems to be this toolchain bug: https://sourceware.org/bugzilla/show_bug.cgi?id=21017 I've had no response from the microblaze maintainer, so please stop generating this warning now. If we get a bug report from a user who actually cares and will test toolchain fixes then we can easily work with them. Many thanks for the very good service this build system provides!
