//! PowerPC AltiVec intrinsics.
//!
//! AltiVec is a brandname trademarked by Freescale (previously Motorola) for
//! the standard `Category:Vector` part of the Power ISA v.2.03 specification.
//! This Category is also known as VMX (used by IBM), and "Velocity Engine" (a
//! brand name previously used by Apple).
//!
//! The references are: [POWER ISA v2.07B (for POWER8 & POWER8 with NVIDIA
//! NVlink)] and [POWER ISA v3.0B (for POWER9)].
