as i specify armv8... as march option, i assume that this an arch64 that is used.
gcc comes with ayufan's ubuntu 18.04 image, so i assume that this arch64 is the default ($gcc -dumpmachine gives aarch64-linux-gnu).

the instructions you showed are NOT a64 simd instructions, it's a32 simd instructions. Smile take a look at ARM ARM, where everything is described. And there is an alphabetical list of appropriate instructions too.
