IMHO there isn't much point in trying to impose a "generic" naming scheme
for the x86. Why?
There's only a few registers.
The 'E' part of the registers can't be accessed invidually.
SI/DI/SP/BP aren't byte-accessible.
Some registers have special purpose. SI/DI/SP source/destination/stack are
easy to remember, but having to remember that, for instance, that these were
r0, r3, r5 (arbitrarily chosen here) would be harder.
On other and properly designed hardware with more registers and a more
coherent opcode map, r0-rxx naming would make sense. But on x86, it makes
about as much sense at a/b's weird "line noise" language.
