# ******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:
# Script arguments are handled uniformly as follows:
# - If the argument does not contain a '|' character, it is appended
# to both command lines.
# - If the argument has a '|' character in it, the text on either side
# of the '|' is appended to the respective command lines. Note that
# you'll have to quote the arg or escape the '|' with a backslash
# so that the shell doesn't think you're doing a pipe.
#
# % tracediff "m5.opt --option1" "m5.opt --option2" [common args]
# For example:
#
# % tracediff m5.opt --opt1 "--opt2|--opt3" --opt4
# would compare these two runs:
# m5.opt --opt1 --opt2 --opt4
# m5.opt --opt1 --opt3 --opt4
#
# If you want to compare two different simulator binaries, put a '|'
# in the first script argument ("path1/m5.opt|path2/m5.opt"). If you
# want to add arguments to one run only, just put a '|' in with text
# only on one side ("--onlyOn1|"). You can do this with multiple
# arguments together too ("|-a -b -c" adds three args to the second
# run only).
