I just committed a patch to gold: http://sourceware.org/ml/binutils/2013-04/msg00026.html . Unfortunately this patch probably won't be in a released version of the GNU binutils for a while. I don't know why this worked with GCC 4.7. I haven't looked into it. ^ permalink raw reply [flat|nested] 5+ messages in thread
