Struct regalloc2::ProgPoint

pub struct ProgPoint { /* private fields */ }

A program point: a single point before or after a given instruction.

Implementations

impl ProgPoint

pub fn new(inst: Inst, pos: InstPosition) -> Self

Create a new ProgPoint before or after the given instruction.

pub fn before(inst: Inst) -> Self

Create a new ProgPoint before the given instruction.

pub fn after(inst: Inst) -> Self

Create a new ProgPoint after the given instruction.

pub fn inst(self) -> Inst

Get the instruction that this ProgPoint is before or after.

pub fn pos(self) -> InstPosition

Get the “position” (Before or After) relative to the instruction.

pub fn next(self) -> ProgPoint

Get the “next” program point: for After, this is the Before of the next instruction, while for Before, this is After of the same instruction.

pub fn prev(self) -> ProgPoint

Get the “previous” program point, the inverse of .next() above.

pub fn to_index(self) -> u32

Convert to a raw encoding in 32 bits.

pub fn from_index(index: u32) -> Self

Construct from the raw 32-bit encoding.

Trait Implementations

impl Clone for ProgPoint

fn clone(&self) -> ProgPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProgPoint

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

Formats the value using the given formatter.

impl Hash for ProgPoint

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 Ord for ProgPoint

fn cmp(&self, other: &ProgPoint) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ProgPoint> for ProgPoint

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

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

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

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

impl PartialOrd<ProgPoint> for ProgPoint

fn partial_cmp(&self, other: &ProgPoint) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
