I see the exact same error on Solaris 8 Sparc using GCC 4.3.2

------- Comment #3 from pinskia at gcc dot gnu dot org  2009-07-23 20:24 -------
This error is correct as we have:
register int overflow __asm__("%g6");
...
__asm__ ( "addcc %2,%3,%0;           addx  %%g0,%%g0,%1" : "=r" (__value), "=r"
(overflow) : "r" (__arg1), "r" (__arg2) : "%g6","cc");

So the asm is saying g6 is clobbered and an output.  How can that be true?  It
cannot be clobbered when it is an output.
