- Subject: Optimisation options turned on at a certain level
Hello,
I'm trying to find where in the gcc documentation the list of optimisations
that are implied by specifying -O3 and -Os with my gcc3.2 install. I could
not find anything yet other than the following:
-O[number] Set optimisation level to [number]
-Os Optimise for space rather than speed
from gcc -v --help
Could someone direct me to where I should be looking for this list of
optimisations that are turned on with the different levels please?
Kind regards
Jonathan
