◆ canonicalizeMapExprAndTermOrder()

static LogicalResult canonicalizeMapExprAndTermOrder ( AffineMap & map )

Canonicalize the result expression order of an affine map and return success if the order changed.

A coefficient array contains a multiplier for every dimension/symbol and a constant term. The canonicalization fails if a result expression is not pure or if the flattening requires local variables that, unlike dimensions and symbols, have no global order.
