Yes but your summary was saying memset was missing which is not correct and
would cause this bug report to be invalid. But in reality you are complaining
that the memset was not needed in the first place why is it being used for
-mtune=cortex-a9 when doing -mtune=cortex-a12 can get away with not needing
memset.
Two different issues :).
