er stupid me, that's obviously a mistake, I copied from a previous run. Here are the correct results:
$ PATH=~/native/bin/:$PATH g++ -O3 -DNDEBUG -DREPEAT=1000 -I../ benchVecAdd.cpp -o benchVecAdd -lrt
$ ./benchVecAdd
7.73s 0.0192771 GFlops
$ PATH=~/native/bin/:$PATH g++ -O3 -DNDEBUG -DREPEAT=1000 -mfpu=neon -mfloat-abi=softfp -I../ benchVecAdd.cpp -o
benchVecAdd -lrt
h$ ./benchVecAdd
2.93s 0.0508572 GFlops
That's ~2.64x faster!
