Re: mfpu=neon and -march=native on aarch64-linux-gnu toolchain

-mgeneral-regs-only is how you turn off SIMD usage. But Note it also turns off floating point too. I don't know why you want to turn off the SIMD usage because all ARMv8-a platforms have it and it is not optional for -a processors. That slide is about AARCH32 (aka A32 aka armv7) usage. Than

Re: mfpu=neon and -march=native on aarch64-linux-gnu toolchain
