<font class="QuotedText">&gt; That's the point of a low-level language. Imho, if you have well-written code in a low-level language, the compiler SHOULD NOT be able to do that much optimisation.</font>

<p>If we would use that definition then modern systems don't have <b>any</b> low-level languages. Not even machine code conforms: CPUs with speculative execution may do massive changes to what you wrote in your code!</p>

Didn't I say that the CPU was an object code INTERPRETER? :-)

But if I'm unable to REASON LOGICALLY about what the CPU is going to do, how on earth am I going to get deterministic (ie it does what I want it to do) behaviour from my program?

It's turtles all the way down and logic (and the ability to debug!) has just gone down the plughole with the bathwater ...

Cheers,
Wol
