--- Comment #67 from Ian Lance Taylor <ian at airs dot com> 2011-06-24 13:21:28 UTC --- We don't need __FRAME_END__ if we use --eh-frame-hdr. We don't need __JCR_END__ if we rename the .jcr section to jcr and use __stop_jcr. These will only work with GNU ld or gold, but that is the only case the .ctors/.dtors code will work anyhow.
