Trait Implementations

impl CastOpInterface for FPTruncOp

fn new(ctx: &mut Context, operand: Value, res_type: TypeHandle) -> Self

where Self: Sized,

Create a new cast operation given the operand.

impl Clone for FPTruncOp

fn clone(&self) -> FPTruncOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstFoldInterface for FPTruncOp

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.
