NEON and VFP system registers
NEON technology and VFP share the same set of system registers.
The following NEON and VFP system registers are accessible in all implementations of NEON and VFP:
FPSCR, the floating-point status and control register.
FPEXC, the floating-point exception register.
FPSID, the floating-point system ID register.
A particular implementation of NEON or VFP can have additional registers. For more information, see the Technical Reference Manual for your processor.
