I had a general question about compiler optimizations and believe
this is a great place to ask!
First of all there are numerous number of compiler optimizations and
they each have their own characteristics..my questions is two-fold:
1. What is the cost/benefit ratio of these optimizations.
2. How do these compiler optimizations interact? i.e. does one
optimization negate the effect of another optimization if done in a
Looking forward to replies..
[Those are awfully general questions. The answers depend greatly on
the language, target machine, and what your goals are. If you're
going to compile a program, run it once for debugging, and throw it
away, the tradeoffs are different than if you're going to run it
100 times a day for the next year. -John]
