Struct CondCode 

pub struct CondCode(/* private fields */);

A condition code, numbered by the target (for x86-64, the cc field of Jcc/SETcc/CMOVcc; see x86_64::cond).

Examples

use backend_lang::mir::CondCode;
use backend_lang::x86_64;
use isa_lang::x86_64::Cond;

let l = x86_64::cond(Cond::L);
assert_eq!(l, CondCode::new(12));
assert_eq!(x86_64::TARGET.cond_name(l), "l");

Implementations

impl CondCode

pub const fn new(code: u8) -> CondCode

The condition with number code.

Examples

use backend_lang::mir::CondCode;

assert_eq!(CondCode::new(4).code(), 4);

pub const fn code(self) -> u8

The condition’s number.

Examples

use backend_lang::mir::CondCode;

assert_eq!(CondCode::new(15).code(), 15);

Trait Implementations

impl Clone for CondCode

fn clone(&self) -> Self

impl Eq for CondCode

impl From<CondCode> for Operand

fn from(c: CondCode) -> Operand

Converts to this type from the input type.

impl Hash for CondCode

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

impl Ord for CondCode

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for CondCode

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CondCode

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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