Enum regalloc2::moves::MoveVecWithScratch

pub enum MoveVecWithScratch<T> {
    NoScratch(MoveVec<T>),
    Scratch(MoveVec<T>),
}

Expand description

A list of moves to be performance in sequence, like a MoveVec<T>, except that an unchosen scratch space may occur as well, represented by Allocation::none().

Variants§

NoScratch(MoveVec<T>)

No scratch was actually used.

Scratch(MoveVec<T>)

A scratch space was used.

Implementations§

impl<T> MoveVecWithScratch<T>

pub fn with_scratch(self, scratch: Allocation) -> MoveVec<T>

Fills in the scratch space, if needed, with the given register/allocation and returns a final list of moves. The scratch register must not occur anywhere in the parallel-move problem given to the resolver that produced this MoveVecWithScratch.

pub fn without_scratch(self) -> Option<MoveVec<T>>

Unwrap without a scratch register.

pub fn needs_scratch(&self) -> bool

Do we need a scratch register?
