Enum VReg 

pub enum VReg {
    RealRegister(usize),
    Virtual(usize),
    Spilled(usize),
}

VReg is a representation of a register in VCode.

Variants

RealRegister(usize)

VReg::RealRegister represents a register that exists in the target architecture.

Virtual(usize)

VReg::Virtual represents a virtual register, of which there are unlimited. These are converted into real registers or spilled registers depending on the register allocator.

Spilled(usize)

VReg::Spilled represents a spilled value on the stack. This variant is used when the register allocator could not fit a value into the limited registers of the target architecture.

Trait Implementations

impl Clone for VReg

fn clone(&self) -> VReg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VReg

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

Formats the value using the given formatter.

impl Display for VReg

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

Formats the value using the given formatter.

impl Hash for VReg

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 VReg

fn eq(&self, other: &VReg) -> 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.
