Lattice point.
Each lattice point consists of a formal conjunction of TensorLoopId
s, together with the identifier of the corresponding tensor expression. The formal conjunction is represented as a set of TensorLoopId
, where that set is implemented as a BitVector
.

This represents a simplified condition under which this tensor expression must execute. Precomputed during codegen to avoid repeated eval.
