Look at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41684#c10 for a list of test failures fixed by disabling fsection-anchors in the arm backend.
Look also at the way in which the PPC backend works around this at http://gcc.gnu.org/ml/gcc-patches/2008-08/msg02194.html Instead of putting in such a work around in the backends, the target independent parts should disable -fsection-anchors for Objective C. -- Summary: Extra Objective C/C++ test failures because of section anchors.
