Nicolas Vasilache 93fd30bac3 [mlir][Linalg] Evolve named ops to use assembly form and support linalg on tensors. ... This revision allows representing a reduction at the level of linalg on tensors for named ops. When a structured op has a reduction and returns tensor(s), new conventions are added and documented. As an illustration, the syntax for a `linalg.matmul` writing into a buffer is: ``` linalg.matmul ins(%a, %b : memref<?x?xf32>, tensor<?x?xf32>) outs(%c : memref<?x?xf32>) ``` , whereas the syntax for a `linalg.matmul` returning a new tensor is: ``` %d = linalg.matmul ins(%a, %b : tensor<?x?xf32>, memref<?x?xf32>) init(%c : memref<?x?xf32>) -> tensor<?x?xf32> ``` Other parts of linalg will be extended accordingly to allow mixed buffer/tensor semantics in the presence of reductions.		2020-09-18 06:14:30 -04:00
