State-Changed-When: Sat Apr 20 14:28:54 2002
State-Changed-Why:
    gcc 3.1 will issue an error on your code:
    
    test3.c: In function `test':
    test3.c:15: output constraint 0 cannot be specified together with "st" clobber
    
    The fix to your code will be to change this line:
    : "=t"(ret): "u"(y), "0"(x): "eax","st");
    
    to:
    
    : "=t"(ret): "u"(y), "0"(x): "eax","st(1)");

 State-Changed-Why:
     With gcc 3.0.3  20011119 (prerelease), I can reproduce your
     ICE.
     
     With gcc version 3.1 20011110 (experimental), I get
     the following warning:
     
     r.c: In function `test': r.c:4: Output constraint 0 cannot be specified together with "st" clobber r.c:11: confused by earlier errors, bailing out
     
     Are you sure your code is not in error?
