mlir-opt version: 22.1.0-rc1
The crash is triggered while processing a tensor.from_elements operation
producing a tensor<1xindex>, which leads to an invalid llvm::cast to
mlir::IntegerAttr and causes a hard assertion failure.
```
mlir-opt --arm-neon-2d-to-intr test.mlir
```
```
module {
func.func @main() {
%0 = ub.poison : index
%1 = tensor.from_elements %0 : tensor<1xindex>
cf.br ^bb1(%1 : tensor<1xindex>)
^bb1(%arg0: tensor<1xindex>):
return
}
}
```
```
mlir-opt: llvm-project-llvmorg-22.1.0-rc1/llvm/include/llvm/Support/Casting.h:560: decltype(auto) llvm::cast(const From&) [with To = mlir::IntegerAttr; From = mlir::Attribute]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
