Struct VirtualReg 

pub struct VirtualReg {
    pub id: u32,
    pub ty: LcnfType,
    pub hint: Option<PhysReg>,
}

A virtual register (pre-allocation).

Fields

id: u32

Unique ID matching the corresponding LcnfVarId.

ty: LcnfType

The LCNF type of this register’s value.

hint: Option<PhysReg>

An optional hint towards a preferred physical register.

Implementations

impl VirtualReg

pub fn new(id: u32, ty: LcnfType) -> Self

Create a new virtual register without a hint.

pub fn with_hint(id: u32, ty: LcnfType, hint: PhysReg) -> Self

Create a virtual register with a physical-register hint.

pub fn reg_class(&self) -> RegClass

Determine which register class this vreg belongs to.

Trait Implementations

impl Clone for VirtualReg

fn clone(&self) -> VirtualReg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtualReg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for VirtualReg

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VirtualReg

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
