No, we are not headed back towards CISC. I'd have to agree with Henry completely. One possible alternative way of looking at this is that CISC technology, especially the VAX, was developed during a period of time when a lot of programs were written in assembler. If you look carefully at the MIPS architechture and the output of its C compiler, you'll soon discover that on a MIPS machine, there is absolutely no reason to program in assembler. Since one of the fundamental tenets of RISC design is that all programs will be written in a high-level language, we aren't going to see instructions sets that are real complicated for the simple fact that the compilers can't deal with the complexity. -- Chuck
