Sure, that's what a typical HLL compiler does. Except, of course, when
it converts it into an entirely different set of instructions, such as
would be appropriate if a and b are pointer types, or floating point, or
structures. BartC didn't mention this, but a=b can also involve implicit
conversions, depending upon the types of 'a' and 'b'. Finally, don't try
to gloss over the memory management details, either. Those also depend
upon the types of 'a' and 'b', and are also subject to considerable
rearrangement by an optimizer.
The type-dependent aspects of that translation require features that go
well beyond the capabilities of anything that can properly be called
only a macro assembler.
