Re: [gimple] assignments to volatile

Nathan, I know that we have RealView available for testing, and I
believe we also have CodeWarrior installed.  Would you like to give
those two a try?

I couldn't get CodeWarrior to play.

RVCT generated code consistent with my proposal. Specifically in:
some_use_of = volatile_object = value;
the volatile object is only written to and not read, regardless of the context of that volatile assignment (be it return expression, conditional expression or serial assignment).

   vobj;
   (void) vobj;

Both of these cause a read of vobj in RVCT (and GCC).
