/// Byte reverse
pub trait Rev {

/// **Keywords**: count leading sign bits, count leading ones, count

/// # Instructions

/// - [`REV`](http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.
/// ddi0419c/index.html):
/// - Description: Reverses the byte order in a register.
/// - Architecture: ARMv6, ARMv7, ARMv8.
/// - Registers: 32 (v6, v7)/64 (v8) bits.
///
/// # Example
///
/// ```
/// # use bitintr::*;
/// let n = 0b1111_1111_1100_1010u16;
/// let m = 0b1100_1010_1111_1111u16;
///
/// assert_eq!(n.rev(), m);
/// assert_eq!(m.rev(), n);
/// ```
