Struct ComputedValue 

pub struct ComputedValue {
    pub op: ComputedOp,
    pub operands: Vec<SsaVarId>,
}

Computed value for common subexpression elimination (CSE).

This represents the result of a computation, enabling recognition of equivalent expressions that can be eliminated.

Fields

op: ComputedOp

The operation that produced this value.

operands: Vec<SsaVarId>

The operands to the operation.

Implementations

impl ComputedValue

pub fn new(op: ComputedOp, operands: Vec<SsaVarId>) -> Self

Creates a new computed value.

pub fn unary(op: ComputedOp, operand: SsaVarId) -> Self

Creates a unary computed value.

pub fn binary(op: ComputedOp, left: SsaVarId, right: SsaVarId) -> Self

Creates a binary computed value.

pub fn normalized(self) -> Self

Normalizes commutative operations for better CSE.

For commutative ops like add/mul, orders operands consistently so that a + b and b + a have the same computed value.
