Having something like this on the mspgcc would be nice. Currently, I have to use inline assembly for all these vector-register-driven ISRs (Timer, USART, NMI etc.) It works and once made, you can forget it, but doing so in 'plain' C would be nicer. OTOH, IAR and CCE require something liek that as they don't offer reliable inline assembly. The GCC is superior here.

This function ensures the compiler that it's first argument is always even and always in range [0...second argument]. So compiler allowed to generate case as efficient table jump without additional checking of switch() statement. And nothing more. You can just replace switch(__even_in_range(ADC12IV,34)) to switch(ADC12IV).
