Hi all,


I'm starting a compiler project. I am wondering if it is worth
ignoring global optimisations for a pascal-type scoped language. About
how much optimisation gain is there to be had there? If its more than
about a third, I probably shouldn't ignore it, but it would simplify
my life quite a bit if I could.
[There's no simple answer to your question. The harder you work, the
better you can optimize. For student projects, I wouldn't bother, it's
enough work to get any correct code at all. -John]
