Struct cranelift_codegen::isa::Encoding

pub struct Encoding { /* fields omitted */ }

Bits needed to encode an instruction as binary machine code.

The encoding consists of two parts, both specific to the target ISA: An encoding recipe, and encoding bits. The recipe determines the native instruction format and the mapping of operands to encoded bits. The encoding bits provide additional information to the recipe, typically parts of the opcode.

Methods

impl Encoding

pub fn new(recipe: u16, bits: u16) -> Self

Create a new Encoding containing (recipe, bits).

pub fn recipe(self) -> usize

Get the recipe number in this encoding.

pub fn bits(self) -> u16

Get the recipe-specific encoding bits.

pub fn is_legal(self) -> bool

Is this a legal encoding, or the default placeholder?

Trait Implementations
