Not if your compiler's optimizer is worth a bother. I have seen at
least one compiler that compiles these to exactly the same code.
And then, memcpy is the right way to do it (as library specs say
that that's the function for this job).
But this shows another VERY alarming symptom of C/C++ infestation:
One shouldn't have to think in the assembler when compilers are able to prove
theorems about your code.
