# Script to simplify using rundiff on trace outputs from two
|
|
# invocations of m5.
|
|
#
|
|
# Note that you need to enable some trace flags in the args in order
|
|
# to do anything useful!
|
|
#
|
|
# If you want to pass different arguments to the two instances of m5,
|
|
# you can embed them in the simulator arguments like this:
|
|
#
|
|
# % tracediff "m5.opt --foo:bar=1" "m5.opt --foo:bar=2" [common args]
|
|
#
|
|
|
|
if (@ARGV < 2) {
|
|
die "Usage: tracediff sim1 sim2 [--trace:flags=X args...]\n";
|
|
}
|
|
|
|
# First two args are the two simulator binaries to compare
|
|
$sim1 = shift;
|
|
$sim2 = shift;
|
|
|
|
# Everything else on the command line is taken to be an m5 argument to
|
|
# be given to both invocations
|
|
$simargs = '"' . join('" "', @ARGV) . '"';
|
|
|
|
# Run individual invocations in separate dirs so output and intermediate
|
|
# files (particularly config.py and config.ini) don't conflict.
