//! # LDAPP
//!
//! This instruction calculates an address from a base register value, loads two 64-bit doublewords from memory, and writes them to two registers. Explicit Memory effects produced by this instruction have AcquirePC semantics, unless both destination registers are XZR. For information about memory ordering semantics, see *Load-Acquire, Load-AcquirePC, and Store-Release* .
