If you need exact control of which instructions are executed, then you
need to write in assembly.  Look at code statements (package
Machine_Code) and intrinsics.  These things are highly implementation
dependent, so you need to read the documentation for the Ada compiler
you're using.

Try to write *most* of the code in portable Ada, and use assembly just
where it's needed.
