--cpu=Cortex-A8 --fpu=VFPv2 -O3 -Otime --vectorizeThe error i'm getting is:armlink: Object main.o attributes are not compatible with provided cpu and fpu attributes.
I searched on internet and i found most people are using this option:-mpfu=neon -ftree-vectorize -mfloat-abi=softfp"i don't know how to set my fpu to neon"
