pretty interesting to see that GCC make shorter code than ADS :)
All benchmarks I've seen on ARM, Keil etc web site show that GCC 
usually produces twice bigger code, while you test show other!

we'll certainly do this, preliminary info we received shows that 
Atmel SAM7 can drive GPIOs twice faster than LPC i.e. 60Mhz LPC can 
drive up to 5Mhz GPIO (12 clocks per port toggle) while SAM7 do the 
same for 6 clocks
