30 # Script to simplify using rundiff on trace outputs from two
33 # ******Note that you need to enable some trace flags in the args in order
34 # to do anything useful!******
36 # If you want to pass different arguments to the two instances of m5,
37 # you can embed them in the simulator arguments like this:
39 # % tracediff "m5.opt --option1" "m5.opt --option2" [common args]
43 die "Usage: tracediff sim1 sim2 [--root.trace.flags=X args...]\n";
46 # First two args are the two simulator binaries to compare
50 # Everything else on the command line is taken to be an m5 argument to
51 # be given to both invocations
52 $simargs = '"' . join('" "', @ARGV) . '"';
54 # Run individual invocations in separate dirs so output and intermediate
55 # files (particularly config.py and config.ini) don't conflict.
56 $dir1 = "tracediff-$$-1";
57 $dir2 = "tracediff-$$-2";
58 mkdir($dir1) or die "Can't create dir $dir1\n";
59 mkdir($dir2) or die "Can't create dir $dir2\n";
61 $cmd1 = "$sim1 $simargs -d $dir1 2>&1 |";
62 $cmd2 = "$sim2 $simargs -d $dir2 2>&1 |";
64 # This only works if you have rundiff in your path. I just edit it
65 # with an explicit path if necessary.
66 $fullcmd = "rundiff '$cmd1' '$cmd2' 2>&1 > tracediff-$$.out";
68 print "Executing $fullcmd\n";
