◆ reindexIndexingMap()

static AffineMap reindexIndexingMap ( AffineMap map )

static

Given an indexing map coming from a LinalgOp indexing, restricted to a projectedPermutation, compress the unused dimensions to serve as a permutation_map for a vector transfer operation.

For example, given a linalg op such as:

%0 = linalg.generic {
     indexing_maps = affine_map<(d0, d1, d2, d3, d4) -> (d4, d0, d2)>,
     indexing_maps = affine_map<(d0, d1, d2, d3, d4) -> (d1, d3)>
   }
  ins(%0 : tensor<2x3x4xf32>)
 outs(%1 : tensor<5x6xf32>)

the iteration domain size of the linalg op is 3x5x4x6x2. The first affine map is reindexed to affine_map<(d0, d1, d2) -> (d2, d0, d1)>, the second affine map is reindexed to affine_map<(d0, d1) -> (d0, d1)>.

◆ vectorizeAsLinalgGeneric()

static LogicalResult vectorizeAsLinalgGeneric	(	OpBuilder &	b,
		LinalgOp	linalgOp,
		SmallVectorImpl< Value > &	newResults
	)

static

Generic vectorization function that rewrites the body of a linalgOp into vector form.

Generic vectorization proceeds as follows:

Verify the linalgOp has one non-empty region.
Values defined above the region are mapped to themselves and will be broadcasted on a per-need basis by their consumers.
Each region argument is vectorized into a vector.transfer_read (or 0-d load). TODO: Reuse opportunities for RAR dependencies. 4a. Register CustomVectorizationHook for YieldOp to capture the results. 4b. Register CustomVectorizationHook for IndexOp to access the iteration indices.
Iteratively call vectorizeOneOp on the region operations.

When broadcastToMaximalCommonShape is set to true, eager broadcasting is performed to the maximal common vector size implied by the linalgOp iteration space. This eager broadcasting is introduced in the permutation_map of the vector.transfer_read operations. The eager broadcasting makes it trivial to detrmine where broadcast, transposes and reductions should occur, without any bookkeeping. The tradeoff is that, in the absence of good canonicalizations, the amount of work increases. This is not deemed a problem as we expect canonicalizations and foldings to aggressively clean up the useless work.

		LinalgOp	linalgOp,

		ArrayRef< CustomVectorizationHook >	customVectorizationHooks
	)

static

Generic vectorization for a single operation op, given already vectorized operands carried by bvm.

Vectorization occurs as follows:

Try to apply any of the customVectorizationHooks and return its result on success.
Clone any constant in the current scope without vectorization: each consumer of the constant will later determine the shape to which the constant needs to be broadcast to.
Fail on any remaining non ElementwiseMappable op. It is the purpose of the customVectorizationHooks to cover such cases.
Clone op in vector form to a vector of shape prescribed by the first operand of maximal rank. Other operands have smaller rank and are broadcast accordingly. It is assumed this broadcast is always legal, otherwise, it means one of the customVectorizationHooks is incorrect.

This function assumes all operands of op have been vectorized and are in the bvm mapping. As a consequence, this function is meant to be called on a topologically-sorted list of ops. This function does not update bvm but returns a VectorizationStatus that instructs the caller what bvm update needs to occur.
