[−][src]Struct cranelift_codegen_meta::cdsl::instructions::InstructionPredicateRegistry

pub(crate) struct InstructionPredicateRegistry {
    map: PrimaryMap<InstructionPredicateNumber, InstructionPredicate>,
    inverted_map: HashMap<InstructionPredicate, InstructionPredicateNumber>,
}

A registry of predicates to help deduplicating them, during Encodings construction. When the construction process is over, it needs to be extracted with extract and associated to the TargetIsa.

Fields

map: PrimaryMap<InstructionPredicateNumber, InstructionPredicate>

Maps a predicate number to its actual predicate.

inverted_map: HashMap<InstructionPredicate, InstructionPredicateNumber>

Inverse map: maps a predicate to its predicate number. This is used before inserting a predicate, to check whether it already exists.

Implementations

impl InstructionPredicateRegistry[src]

pub fn new() -> Self[src]

pub fn insert(
    &mut self,
    predicate: InstructionPredicate
) -> InstructionPredicateNumber[src]

pub fn extract(
    self
) -> PrimaryMap<InstructionPredicateNumber, InstructionPredicate>[src]
