G includes MAFD extensions for non-embedded (I) applications. That's multiplication and division, atomics, single and double-precision floating point. It also includes the control/status register and a instruction-fence instruction. I think it's there to mean "the base plus the standard bits that people generally want in a processor if they're writing C for it".
