State-Changed-Why:
    The code is buggy.  It's trying to use x86 inline assembly on
    a sparc and (predictably) failing miserably.  It is in essence
    the same as PR 5099.

 Hi,
 
 the following code snippet reproduces the ICE on mips-sgi-irix6.5
 with gcc 3.0.3 and gcc 3.1 20011210:
 
 void f()
 {
   int i;
   asm ("xchgw %0,%1" : "=q" (i), "=m" (i) : "m" (i), "0" (0));
 }
 
 Just compile with "g++ -c".
 
 This seems to be the same bug as in PR 4954.
 
 Greetings,
 Volker Reichelt
