optimization : speed vs size

  I would like to get pointed to documentations, preferably web available.
(html, PS, whatever as long as i can read it) about a debate whether the
code (nowadays) should be optimized for speed of execution or code size.


while i am at it, is there any tool (or something i dunno) that is used to
measure to quality of code produced by a compiler (x86 only) or some kind
standard source which can then be used to watch the produced code.

[Depends on your target platform and audience -- the embedded market cares
deeply about code size, most others more about speed, but even if you care
about speed, a loop that fits in your chip's cache will often run a lot
faster than a nominally slow one that doesn't. -John
