Most of the benefits of extra registers in most cases would be found in the hardware registers and register renaming found in most x86 processors these days. The K7 microarchitecture has something like 88 physical registers, even though the x86 architecture only has 8 logical registers per thingy (you know, the gp/integer thingy, the floating point thingy, etc). I was personally looking for 32 general purpose registers in x86-64. I guess others have convinced me into thinking that this would be ideal for the moment (eg, not too much waste of transistors), so I was a bit disappointed when the number turned out to be 16.     -JC
