Implementations

impl ICmpOp

pub fn get_attr_icmp_predicate<'a>( &self, ctx: &'a Context, ) -> Option<Ref<'a, ICmpPredicateAttr>>

Get a Ref to the value of the attribute named icmp_predicate. The Ref is a borrow of the containing Operation object.

pub fn set_attr_icmp_predicate(&self, ctx: &Context, value: ICmpPredicateAttr)

Set the value of the attribute named icmp_predicate.

impl ICmpOp

pub fn new( ctx: &mut Context, pred: ICmpPredicateAttr, lhs: Value, rhs: Value, ) -> Self

Create a new ICmpOp

pub fn predicate(&self, ctx: &Context) -> ICmpPredicateAttr

Get the predicate

Trait Implementations

impl Clone for ICmpOp

fn clone(&self) -> ICmpOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstFoldInterface for ICmpOp

fn check_fold( &self, ctx: &Context, ops: &[Option<AttrObj>], ) -> Vec<Option<AttrObj>>

Given a slice operand_attrs corresponding to each operand, indicating a known compile time constant value for that operand (if any), returns a vector corresponding to each result, indicating the folded (inferred constant) value, if any.

fn fold_in_place( &self, ctx: &mut Context, ops: &[Option<AttrObj>], rw: &mut dyn Rewriter, ) -> IRStatus

Given a slice operand_attrs corresponding to each operand, indicating a known compile time constant value for that operand (if any), attempts to fold the op in place using the provided rewriter. Assumes that rewriter is positioned just before the op to be folded.

fn fold_with_materialization( &self, ctx: &mut Context, operand_attrs: &[Option<Box<dyn Attribute>>], rewriter: &mut dyn Rewriter, ) -> IRStatus

A helper for implementing fold_in_place by materializing the constants inferred by check_fold.

impl Hash for ICmpOp

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.

Get the underlying IR Operation

fn get_opid(&self) -> OpId

Get this Op’s OpId

fn get_opid_static() -> OpId

Get this Op’s OpId, without self reference.

fn get_concrete_op_info() -> (fn(Ptr<Operation>) -> OpBox, TypeId)

where Self: Sized,

Get details about the concrete Op type.

Register Op in Context and add it to its dialect.

fn loc(&self, ctx: &Context) -> Location

Get Op’s location

impl Parsable for ICmpOp

type Arg = Vec<(Identifier, Location)>

Type of the argument that must be passed to the parser.

type Parsed = OpBox

fn parse<'__pliron_parse>( state_stream: &mut StateStream<'__pliron_parse>, arg: Self::Arg, ) -> ParseResult<'__pliron_parse, Self::Parsed>

Define a parser using existing combinators and call into on [Parser::parse_stream] to get the final ParseResult. Use state_stream.state as necessary.

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

Tests for self and other values to be equal, and is used by ==.

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

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