4.6. NEON and floating-point registers

In addition to the general-purpose registers, ARMv8 also has 32 128-bit floating-point registers labeled V0-V31. The 32 registers are used to hold floating-point operands for scalar floating-point instructions and both scalar and vector operands for NEON operations. NEON and floating-point registers are also covered in Chapter 7 AArch64 Floating-point and NEON.
