# Description
mlir-opt version: 22.1.0-rc1
Running mlir-opt with the --xegpu-propagate-layout pass crashes if the MLIR module contains an llvm.func declaration, even if the rest of the operations are valid. Commenting out the llvm.func declaration prevents the crash. The crash happens during an LLVM type cast and seems unrelated to the other operations in the function.
# Reproduce
location: If the **llvm.func** is commented out, the crash no longer occurs.
```mlir
module {
llvm.func @some_function()
}
```
```
mlir-opt --xegpu-propagate-layout test.mlir
```
```
mlir-opt: /mnt/sdd1/mlir/tool/llvm-project-llvmorg-22.1.0-rc1/llvm/include/llvm/Support/Casting.h:560: decltype(auto) llvm::cast(const From&) [with To = mlir::LLVM::LLVMFunctionType; From = mlir::Type]: 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.
