◆ doubleBuffer()

static bool doubleBuffer	(	Value	oldMemRef,
		AffineForOp	forOp
	)

static

Doubles the buffer of the supplied memref on the specified 'affine.for' operation by adding a leading dimension of size two to the memref.

Replaces all uses of the old memref by the new one while indexing the newly added dimension by the loop IV of the specified 'affine.for' operation modulo 2. Returns false if such a replacement cannot be performed.
