Re: [arm-gnu] targeting qualcomm scorpion core

Thanks, Carlos!

Do you know if using -march=armv7-a with scorpion will generate code at the
same optimization level as if I used -mcpu=coretex-a8/9 with a cortex A8/9?
For purposes of competitive analysis, I'm just wondering whether my results
would be apples-to-apples.
