util/tracediff
<http://reviews.gem5.org/r/1021/#comment2564>

    Don't you want to fold the if & while together into:
    
      while (@ARGV >= 1 && ($ARGV[0] eq '-n'|| $ARGV[0] eq '-p'))
    
    otherwise I think you could have a problem if someone ran:
    
       ./tracediff -n
    
    because the while loop will iterate checking $ARGV[0] even if all the args 
have been consumed.
