//! A Cranelift-specific x64 assembler.
//!
//! All instructions known to this assembler are listed in the [`inst`] module.
//! The [`Inst`] enumeration contains a variant for each, allowing matching over
//! all these instructions. All of this is parameterized by a [`Registers`]
//! trait, allowing users of this assembler to plug in their own register types.
//!
//! ```
//! # use cranelift_assembler_x64::{Fixed, Imm8, inst, Inst, Registers};
//! // Tell the assembler the type of registers we're using; we can always
//! // encode a HW register as a `u8` (e.g., `eax = 0`).
//! pub struct Regs;
//! impl Registers for Regs {
//!     type ReadGpr = u8;
//!     type ReadWriteGpr = u8;
//!     type WriteGpr = u8;
//!     type ReadXmm = u8;
//!     type ReadWriteXmm = u8;
//!     type WriteXmm = u8;
//! }
//!
//! // Then, build one of the `AND` instructions; this one operates on an
//! // implicit `AL` register with an immediate. We can collect a sequence of
//! // instructions by converting to the `Inst` type.
//! let rax: u8 = 0;
//! let and = inst::andb_i::new(Fixed(rax), Imm8::new(0b10101010));
//! let seq: Vec<Inst<Regs>> = vec![and.into()];
//!
//! // Now we can encode this sequence into a code buffer.
//! let mut buffer = vec![];
//! for inst in seq {
//!     inst.encode(&mut buffer);
//! }
//! assert_eq!(buffer, vec![0x24, 0b10101010]);
//! ```
//!
//! With an [`Inst`], we can encode the instruction into a code buffer; see the
//! [example](Inst).
