Yes, DJ did point out this missing constraint in my patch. I have posted this and committed this patch last month itself,
http://gcc.gnu.org/ml/gcc-patches/2013-06/msg00643.html

It does seem to have got submitted to gcc-cvs and I am able to see this change when I do a svn update,
http://gcc.gnu.org/ml/gcc-cvs/2013-06/msg00409.html

Please correct me if I am wrong on this.
