If I am building code using arm-poky-linux-gnueabi-g++ / arm-poky-linux-gnueabi-gcc from the SDK generated by 'bitbake meta-toolchain', should I be using options like -mcpu=cortex-a9, -mfpu=neon, -mfloat-abi=softfp, etc.. ? And if so what would be the recommended options for the best performance? (This code would be specific to the iMX6D)
