[Bug optimization/14682] [tree-ssa] error: Invalid operand to binary operator

Here is a version which uses char instead of long/long long's:
int __atomic_readv_replacement(unsigned char iov_len, int count, int i) {
    unsigned char bytes = 0;
    if ((unsigned char)((char)127 - bytes) < iov_len)
      return 22;
    return 0;
}

The problem is that fold is converting 127 <  iov_len into (char)( iov_len) < 0 which is 
right but it is not gimple.
