However, if you are developing embedded applications in C or

I don't think it's possible to emphasize that last point
enough.

Especially if you're developing for a small processor you're
never going to be very successful if you don't know how the
code generation differs for logically equivalent blocks of code.

The situation is not so problematic with C, but if you insist of using
C++ in some embedded project, you _really_ have to understand, what
resources a specific construct will require on your platform.
