In the grander scheme, the reliance on late LICM was deemed a necessary risk. #### Putting it Together + As it stands, the six properties above define the semantics of a `linalg.generic` op. It is an open question whether all of these semantics are strictly necessary in practice and whether some should or could be derived -automatically while still maintaining the [core guiding -principles](#guiding_principles). +automatically while still maintaining the +[core guiding principles](#guiding_principles). For the time being, we have settled on the combination of these properties because of empirical evidence building and working on multiple high-level compilers. As we lay those down and engage more with the community, we expect multiple rounds of discussions and design changes to the original architecture. -### Tensors and Buffers: Conventions and Limitations - -Tensors are immutable SSA values, buffers are mutable regions of memory subject -to side-effects and aliasing. As a consequence, output buffers are passed as -operands whereas output tensors are new SSA values corresponding to op results. -Inputs can be arbitrary tensors or buffers and are always passed as operands. - -The following convention is currently in-flight and is in the process of -replacing other existing conventions. The following convention currently applies -to "named" structured ops which are auto-generated by the linalg-ods tool. - -The convention adopted is as follows: - -1. A first block of `ins` op operands hold read-only inputs of ShapedType. -2. An optional second block of `outs` op operands hold read-write output - buffers of MemRefType. -3. An optional third block of `init` operands hold initialization tensors of - RankedTensorType. Such tensors can appear when the op performs a reduction - and returns a tensor. - -Structured ops with fully parallel semantics, have empty `init`. They may either -write in-place into `outs` buffers or return new tensors. - -Structured ops with reduction semantics and output tensor(s) however have -additional restrictions: - -1. They can only return a single tensor for now. -2. They cannot have any output buffer operand (i.e. `outs` is empty). -3. They have exactly one `init` tensor of the same type as the unique output - tensor. Such an `init` tensor does not have an explicit associate indexing - map. Instead the map of the result tensor is used to signify that the `init` - and the `result` are "tied". - -Points 1. and 2. keep complexity of the representation in check by allowing only -a single result tensor, when reductions are present. - -Point 3. is related to the fact that SSA values cannot represent in-place -updates. Instead, linalg adopts a similar convention that exists in e.g. -`vector.outerproduct`: the value that is reduced into is passed as an explicit -argument and a new result of the same shape is produced. - -It is expected buffer allocation will fold this last input onto the result in a -single output buffer argument, which is why the same indexing map is required: -the last input operand is said to be "tied" to the result. - -Alternative, more complex representations, would allow for: - -1. Multiple results and `init` tensors in arbitrary orders, which could be - captured by an extra ArrayAttr of position pairs. -2. Relaxing the conditions on the indexing map equalities on the each pair and - e.g. allow implicit broadcasts of the input. - -These representations are deemed unnecessarily complex for now and are left for -future discussion. - -As an illustration, the syntax for a `linalg.matmul` writing into a buffer is: - -``` -linalg.matmul ins(%a, %b : memref, tensor) - outs(%c : memref) -``` - -, whereas the syntax for a `linalg.matmul` returning a new tensor is: - -``` -%d = linalg.matmul ins(%a, %b : tensor, memref) - init(%c : tensor) - -> tensor -``` - ### Data Representation: Views -The current implementation uses the [Strided MemRef (a.k.a View)]( -https://groups.google.com/a/tensorflow.org/forum/#!topic/mlir/MaL8m2nXuio) + +The current implementation uses the +[Strided MemRef (a.k.a View)](https://groups.google.com/a/tensorflow.org/forum/#!topic/mlir/MaL8m2nXuio) abstraction.
