[Bug c/34873] varasm.c:3387: warning: right shift count >= width of type

This is the code:
        const int shift = sizeof (hashval_t) * CHAR_BIT;
        const int n = sizeof (HOST_WIDE_INT) / sizeof (hashval_t);
        int i;

        h ^= (hashval_t) hwi;
        for (i = 1; i < n; ++i)
          {
            hwi >>= shift;
            h ^= (hashval_t) hwi;
          }


This code is dead if sizeof (HOST_WIDE_INT) == sizeof (hashval_t).


This is a bug in the 4.1.2 you are using and not in the current sources.
