--- Comment #22 from Jacob Lifshay <programmerjake at gmail.com> ---
adding pseudo-code...I decided grevw should be defined to leave the MSB word
cleared -- specifically zero-extending because that allows the compiler to skip
zero-extension instructions that could otherwise be needed. I picked
zero-extension rather than sign-extension because that doesn't require copying
the sign bit, potentially saving wiring.
