Re: Does ObjectAda optimize at all??

T.E.D. says

<<However, if ObjectAda doesn't do variable optimization, loop unrolling,
subprogram inlining, etc., then these folks are right to do this, even though
they drasticly worsen the maintainability of the code. That is why I think it
is a disservice to your customers to not provide optimizations, even if they
never specificly ask for them.

In my experience, programmers often do not know enough to know whether
such manual optimizations help or hurt. They often end up not only
trashing the code, but also making it run nmore slowly. For example,
it takes a careful analysis of icache usage to know whether loop
unrolling is helpful.

At the very least, you shoudl only indulge in this kind of low level
optimziation of your coded if (a) profiling shows that there is a
potential for improvement and (b) testing shows the change is in fact helpful
