13.2. General-purpose registers

The NEON and VFP coprocessor shares the same register bank. This is distinct from the ARM register bank.

You can reference the NEON and VFP register bank using three explicitly aliased views, as described in the following sections.

Figure 13.1 shows the three views of the register bank and the way the word, doubleword, and quadword registers overlap.
