Due to some lucky circumstances, I recently had the chance to appear in one of the biggest German gaming podcasts, Stay Forever, to talk about the technology of RollerCoaster Tycoon (1999). It was …
Citation needed! Processors have had multiplication in silicon since forever, and compiler writers aren’t stupid. You can even check on https://godbolt.org/ with old versions. I bet you can’t find a compiler from 1999 that won’t optimize an unsigned integer multiply to a bit shift without turning off optimisations.

C existed for almost a decade, before they added this specific optimization to compilers in late 1970
I was not referencing particularly RCT and was just trying to explain, what optimizations mean on that level, be it automatic or manual.
