That's a pretty fair generalization. The inability of compilers to
make effective use of the full range of instructions on CISC
architectures such as the VAX was a lot of the inspiration behind
modern RISC ("modern" as opposed to the very similar load/store
architectures designed by Cray for the CDC 6600 and friends, back in
the 1960's).
