I sometimes wonder whether that's a better idea for these micro-optimizations, rather than looking at the assembly code and trying to coax the compiler into generating what you want.

That said, I'm not keen on "argue and you're off the project" work environment.

That would unironically be easier to understand than doing *rwr-- = x.
