Together with the registers returned by [[VFPSupport_Features 0]], these registers describe which version of the VFP/NEON architecture is implemented and which optional features are supported. Registers R1-R3 are reserved for returning additional registers which are introduced in future CPU architecture versions. h4. Notes This call was introduced in VFPSupport 0.13. h4.
