Subject: stats: Add more information to uninitialized error
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=824c87634d2d0606f9f62e8a3383c9a056069125;p=gem5.git

stats: Add more information to uninitialized error

ClockedObject was changed to require its regStats() to be called from every
child class. If you forget to do this, the error was indecipherable. This
patch makes the error more clear.
