30# Script to simplify using rundiff on trace outputs from two
31# invocations of m5.
32#
33# ******Note that you need to enable some trace flags in the args in order
34# to do anything useful!******
35#
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:
38#
39# % tracediff "m5.opt --option1" "m5.opt --option2" [common args]
40#
41
42if (@ARGV < 2) {
43 die "Usage: tracediff sim1 sim2 [--root.trace.flags=X args...]\n";
44}
45
46# First two args are the two simulator binaries to compare
47$sim1 = shift;
48$sim2 = shift;
49
50# Everything else on the command line is taken to be an m5 argument to
51# be given to both invocations
52$simargs = '"' . join('" "', @ARGV) . '"';
53
54# Run individual invocations in separate dirs so output and intermediate
55# files (particularly config.py and config.ini) don't conflict.
56$dir1 = "tracediff-$$-1";
57$dir2 = "tracediff-$$-2";
58mkdir($dir1) or die "Can't create dir $dir1\n";
59mkdir($dir2) or die "Can't create dir $dir2\n";
60
61$cmd1 = "$sim1 -d $dir1 $simargs 2>&1 |";
62$cmd2 = "$sim2 -d $dir2 $simargs 2>&1 |";
63
64# This only works if you have rundiff in your path. I just edit it
65# with an explicit path if necessary.
66$fullcmd = "rundiff '$cmd1' '$cmd2' 2>&1 > tracediff-$$.out";
67
68print "Executing $fullcmd\n";
