Will installing the Dec2002gccUpdater.pkg (gcc 3.3) allow me to
generate G5 optimized code using Jaguar and a G4 machine?
Yes.
How important is this?
That depends on your application. Just using the compiler's built-in
G5 optimizations probably won't do all that much for most applications.
Doing dedicated G5 optimization on performance-critical routines,
though, could result in significant performance boosts depending on how
many independent instructions you can keep in-flight at once.
You'll definitely want to install the CHUD tools so you can use the
Shark profiler. This will point out the performance hot-spots in your
code. You'll want to run your application under CHUD on both a G4 and
a G5, because the performance characteristics of the processors are
different. Nonetheless, it would not be unreasonable to guess that
some G4 performance hot-spots could also benefit from G5 optimization
as well.
