Re: [DUG] ShortInt, SmallInt

Thanks Neven, but I think you'll find that the 486 was CISC as were 
Pentiums, starting with the Pentium Pro the Intel went down the CISC 
interface / RISC core (where complex instructions were broken down into 
a reduced instruction set making them more easily pipelined) - they 
obviously could not just go RISC (like the PowerPC) due to the fact that 
it would make them incompatible with the x86 instruction set.

But it has been a long time since I studied this kind of stuff so I 
could be wrong (and hopefully forgiven).

My understanding is the the 386 was a CISC the 486 introduced a RISC
instruction set, For what it is worth you may consider a CISC 
instruction as
a series of RISC instructions (microcode) in fact this is how they are 
implemented
