# Description
Running mlir-opt --test-arm-sme-tile-allocation on a module containing arm_sme.zero (or other ArmSME tile ops) that appear inside nested regions triggers an assertion in TileAllocation.cpp
# Reproduce
mlir-opt version: 22.1.0-rc1
location: If the **arm_sme.zero** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = arm_sme.zero : vector<[8]x[8]xbf16>
%1 = ptr.type_offset vector<[8]x[8]xbf16> : index
affine.if affine_set<(d0) : (d0 >= 0)>(%1) {
%2 = arm_sme.zero : vector<[8]x[8]xbf16>
}
return
}
}
```
```
mlir-opt --test-arm-sme-tile-allocation test.mlir
```
```
mlir-opt: /mnt/sdd1/sbw/mlir/tool/llvm-project-llvmorg-22.1.0-rc1/mlir/lib/Dialect/ArmSME/Transforms/TileAllocation.cpp:356: {anonymous}::generateOperationNumbering(mlir::FunctionOpInterface)::<lambda(mlir::arm_sme::ArmSMETileOpInterface)>: Assertion `&op == nestedOp.getOperation() && "ArmSME tile allocation does not support nested regions"' 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.
