Hey all,

Now that the CheckerCPU is back from the dead, I know that it would be
extremely useful for me to create a few regression tests for it to
make sure it doesn't fall back into disrepair.  I'm not quite sure how
to go about this because currently the checker is a compile time
option.  The gem5 wiki shows how to make a new regression test but not
for this particular case were the sim would have to recompiled first
before running the test.   Any pointers on this?  Or should I follow
Gabe's lead and make the USE_CHECKER compile time variable a runtime
variable instead? This would simplify the regression process, but
would add overhead in the O3 cpu as it would have to check on every
commit whether or not to call the checker.  Thoughts?

Geoff
