Detailed Description

A variable that can be added to the constraint set as a "column".

The value bounds infrastructure can compute bounds for variables and compare two variables.

Internally, a variable is represented as an affine map and operands.

Variable() [3/6]

ValueBoundsConstraintSet::Variable::Variable	(	Value	shapedValue,
		int64_t	dim
	)

Construct a variable for a dimension of a shaped value.

Variable() [4/6]

ValueBoundsConstraintSet::Variable::Variable	(	OpFoldResult	ofr,
		std::optional< int64_t >	dim
	)

Construct a variable for an index-typed attribute/SSA value or for a dimension of a shaped value.

A non-null dimension must be provided if and only if ofr is a shaped value.
