I have been experimenting a bit with the gcc optimizations. I have not run into any problems, but I am wondering what others' experiences have been so far.

I used -O2 and got a 40% reduction in .MOD file size. Speed improvement was slight but noticeable.

-O3 did not seem to do anything that -O2 did not, and the file size was slightly (1K) larger.

So far I did not work with ARM GCC compiler. I wonder if anybody compared performance and space optimization of GCC with respect to ARM compiler. It will be interesting to see.
