Struct Move 

pub struct Move {
    pub dst: Loc,
    pub src: Source,
    pub class: RegClass,
}

One copy of a parallel copy: dst := src, of register class class.

Examples

use backend_lang::moves::Move;
use backend_lang::x86_64::{GPR, RAX, RBX};

let m = Move::new(RAX, RBX, GPR);
assert_eq!(m.class, GPR);

Fields

dst: Loc

The destination.

src: Source

The source.

class: RegClass

The class of the value moved, which picks scratch and temporary registers and the width of the move.

Implementations

impl Move

pub fn new(dst: impl Into<Loc>, src: impl Into<Source>, class: RegClass) -> Move

dst := src of class.

Examples

use backend_lang::mir::StackSlot;
use backend_lang::moves::{Loc, Move, Source};
use backend_lang::x86_64::{GPR, RSI};

let spill = Move::new(StackSlot::new(0), RSI, GPR);
assert_eq!(spill.dst, Loc::Slot(StackSlot::new(0)));
assert_eq!(spill.src, Source::from(RSI));
