<div>The compiler isn't a valid case because the input source is different (because of the very changes made to said compiler). It needs to be a project that doesn't share anything with the compiler (except the run-time libraries), so the source code is exactly the same so that when it is built, it runs the same no matter which version of the compiler it was built with.</div><div><br>
</div><div>I'm viewing it as a bit of a scientific experiment, where only a single variable is changed, namely the compiler used. The compiled program should produce exactly the same output and otherwise behave the same way, so that any time metrics reflect only how long it takes to complete and hence is reflective only of the quality of the machine code, not what the program is doing... if that makes any sense.</div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">You could always build an unmodified compiler with your modified one ;) </div><div dir="auto"><br></div><div dir="auto">Regards, </div><div dir="auto">Sven </div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
