Public Attributes
bool	empty
	True if no cross-iteration dependence exists.
std::string	deltas_str
	ISL set string representing the delta set (empty string if no dependence).
std::vector< std::string >	dimensions
	Dimension names in order, matching the ISL set dimensions.

Detailed Description

Represents the set of dependence distance vectors between two access patterns.

When two memory accesses touch overlapping cells at different iterations, this struct captures the full set of iteration-distance vectors as an ISL set string. The dimensions of the delta set correspond to the non-constant symbols (loop induction variables) in the order listed in dimensions.
