Re: Compiled Code density RISC v.s. CISC. Is your question theoretical or practical? The 68K is a CISC, but it's not really a code-density king. I'd rather hear specs about the NS32532, or even VAX code. Try comparing a SPARC to a Xerox Dandelion (with bytecode instructions). The Dandelion was "tuned" the instruction set in insane ways, based on statistical analysis of thousands of lines of MESA (glorified PASCAL). For instance, they might add instructions like load-immediate-0, -1, -2, -4, -7, since 0,1,2,4, 7 were the the most common constants found in most programs.
