Hi Mike,
We only have MISRA-C checking in our compiler at present; we do not have MISRA-C++ checking, unfortunately.
Having a quick search, there are static C/C++ analysis plugins available for Eclipse, though I am not sure of the cost (as many appear to be professional solutions), but there are products such as Goanna Studio for Eclipse, C/C++ Test for Embedded from Parasoft, etc.
Regards,
Craig.
