scons: Use the new test framework from scons
Rewrite the SCons script responsible for launching tests to use the
new test framework. The biggest visible change after this changeset is
that SCons no longer produces a "status" file in test build
directories. Instead, it creates a status.pickle file. That file can
be inspected using the new tests.py script. Another visible change is
that timed out tests are now reported as failed rather than a using a
separate summary message.
Since the pickle file will remain in the build directory after running
tests, it's now possible to convert the test results into other
formats. For example:
./tests/tests.py show --format junit -o junit.xml \
`find build/ -name status.pickle`
To better facilitate running outside of scons, there is now a set of
targets that generate test listings that can be used by the test
script. There are currently three targets, quick.list, long.list, and
all.list. For example:
scons build/ARM/tests/opt/all.list
for F in `cat build/ARM/tests/opt/all.list`; do
./tests/tests.py run build/ARM/gem5.opt $F
done
