Accessing the AArch32 feature identification registers

Software can identify the Advanced SIMD and floating-point features using the feature identification registers in the AArch32 execution state.

You can access the feature identification registers in the AArch32 execution state using the VMRS instruction, for example:

VMRS <Rt>, FPSID ; Read FPSID into Rt
VMRS <Rt>, MVFR0 ; Read MVFR0 into Rt
VMRS <Rt>, MVFR1 ; Read MFFR1 into Rt
VMRS <Rt>, MVFR2 ; Read MVFR2 into Rt
