I can see why some of this ordering would be subject to disagreement,
but I would hope that there also are partial orderings that are NOT
The general rule of software engineering is that correctness comes
first, performance and schedule after that.
In the list above, "correctness" covers the first three, but they are
not all the same. In my view, correct code generation is vastly more
important than anything else. After that comes fewer ICEs. (ICEs are
a pain but if there's a workaround, you can still get your job done.
Bad code is much nastier because you may not realize you have a
problem to work around.) As for standards conformance, I'm not sure
I'd even that high enough to have it trump some of the performance
things, but then again I'm not a language lawyer.
In any case, is there any disagreement that correct code generation is
absolutely the most important concern? If so, why?
