8.3 Fused Multiply-Add extension for NEON

The Fused Multiply-Add extension optionally extends the NEON architecture.

It provides NEON instructions that perform multiply and accumulate operations with a single rounding step, so suffers from less loss of accuracy than performing a multiplication followed by an add.

The fused multiply-add instructions are only available on NEON systems that implement the fused multiply-add extension.
