From: Peng Fan <peng....@nxp.com> Some compilers default use hardfloat to generate instructions, so it will use some FPU/NEON registers to do some optimization.
However some inmates might use FPU/NEON registers do some calculation such as vector/audio and etc. So we need to disable jailhouse use these registers. Use `-march=armv8-a+nofp` for this.
