Struct cranelift_codegen_meta::cdsl::recipes::Register

pub(crate) struct Register {
    pub regclass: RegClassIndex,
    pub unit: u8,
}

A specific register in a register class.

A register is identified by the top-level register class it belongs to and its first register unit.

Specific registers are used to describe constraints on instructions where some operands must use a fixed register.

Register instances can be created with the constructor, or accessed as attributes on the register class: GPR.rcx.

Fields

regclass: RegClassIndex

unit: u8

Methods

impl Register

pub fn new(regclass: RegClassIndex, unit: u8) -> Self

Trait Implementations

impl Clone for Register

fn clone(&self) -> Register

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Register

impl Eq for Register

impl Hash for Register

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Into<OperandConstraint> for Register

fn into(self) -> OperandConstraint

Performs the conversion.

impl PartialEq<Register> for Register

fn eq(&self, other: &Register) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Register) -> bool

This method tests for !=.
