Yes, and if platforms such as the B5500 had prevailed, we wouldn't be
worrying about assembly language programming.
If you have memory bandwidth to burn, but few CPU transistors, you
should make the compiler or programmer decide what to put in which
temporary storage for how long, and give them extra address bits to
specify that storage (ie, registers). OTOH, if memory bandwidth is tight,
but CPU transistors are cheap, you should make your addressing as short as
possible (eg, implied registers and stack) and let the CPU cache etc
control the movement of stuff in the storage heirarchy.
