It is still unclear, Mr Wagner... are you saying that since all machines
are 64-bit architectures then the differences between all
machine-instructions are null... or that the example I chose to
demonstrate how machine-instruction efficiencies might need to be
considered is, as was clearly labelled at the start, 'trivial'?

I didn't say that, although it happens to be true. Generally, all
instructions run in one clock, unless they operate on multiple words.

That's it. The example you chose doesn't support your point .. not
even trivially.

Not being familiar with 'all instructions' on all possible platforms I can
neither agree nor disagree with this assertion.

If the flaw is in the admittedly trivial example, Mr Wagner, and not the
principle upon which the example is based, then perhaps a person of
knowledge, sound principles and generosity of spirit might examine the
depths and ignore the trivial... the question remains, it seems, open.
