State-Changed-When: Sat Mar  9 05:59:58 2002
State-Changed-Why:
    Simplified into:
    typedef struct { unsigned long a; unsigned int b, c; } A;
    typedef struct { unsigned long a; A *b; int c; } B;
    
    static inline unsigned int
    bar (unsigned int x)
    {
      unsigned long r;
      asm ("" : "=r" (r) : "0" (x));
      return r >> 32;
    }
    
    int foo (B *x)
    {
      A *y;
      y = x->b;
      y->b = bar (x->c);
      y->c = ({ unsigned int z = 1; (z << 24) | (z >> 24); });
    }
