Helper class to generate common gem5 tests using verifiers.

details about the gem5 run.

into a suite that will be ran after a gem5 run.
:param gem5_args: An iterable with arguments to give to gem5. (Arguments
that would normally go before the config path.)
:param valid_isas: An iterable with the isas that this test can be ran
for. If None given, will run for all supported_isas.

this test can be ran for. (E.g. opt, debug)
