Nope, it's not gcc, because the instructions in question
are hand-coded in assembly by gcc.  See
http://sources.redhat.com/ml/binutils/2004-04/msg00687.html
Nobody replied to that, so maybe I'll have to learn
enough sparc64 assembly myself to decide whether this is
a binutils problem (overeager check) or a glibc coding error.
I wish some sparc64 expert would have a look.
