// RUN: torch-mlir-opt -split-input-file -verify-diagnostics %s -torch-verify-invariants-before-backend-lowering
Generalize support for elementwise ops. We plumb through e2e a fair number of interesting cases: - unary, binary, ternary elementwise ops - ops like `torch.aten.add.Tensor` that also take a scalar parameter - static size-1 broadcasting We allow the static size-1 broadcasting case, but emit a runtime error in the case of dynamic size-1 broadcasting. This seems like a sweet spot subset of things that can be lowered directly to linalg, while not being overly constraining to users. This is consistent with what IREE is doing for CHLO->Linalg lowering as well ([code](https://github.com/google/iree/blob/50bf7a87e465d2048c527bc27724edde40519b7e/iree/compiler/InputConversion/MHLO/BroadcastingToLinalgPatterns.cpp#L1)). To test the static size-1 case, we added support for the `torch.aten.unsqueeze` op and lowering for it through `linalg.tensor_expand_shape`. This involved a generalization of `MaximizeValueSemantics` able to handle it (the solution there also works for `torch.aten.flatten.using_ints` which we need for ResNet anyway) Also, a few minor additional changes: - Add `VerifyInvariantsBeforeBackendLowering` pass, which catches a large class of errors before we get to backend lowering (now that we are doing dialect conversion, the errors are way nicer if we just emit them up front rather than in the guts of a random pattern). - Minor change to RefBackend to allow `linalg.tensor_expand_shape`. Recommended review order: - e2e tests in elementwise.py - `ConvertElementwiseOp` in TorchToLinalg.cpp + elementwise.mlir test - `ConvertAtenUnsqueezeOp` in TorchToLinalg.cpp + unsqueeze.mlir test - RefineTypes.cpp + tests - MaximizeValueSemantics changes + test - VerifyInvariantsBeforeBackendLowering pass + test

mlir: bump llvm tag to 5380e3 (#856) In addition to updating the llvm-project submodule, this patch also: 1. updates shape functions and tests so that `func` and `call` operations refer to the `func` dialect 2. avoid duplicate registration of dialects
