[mlir] -ensure-debug-info-scope-on-llvm-func crashes #108390

git version: 8168088f0a9015b

system: Ubuntu 18.04.6 LTS

reproduce with: mlir-opt -ensure-debug-info-scope-on-llvm-func a.mlir

a.mlir:

module {
  func.func @test(%arg0: memref<3x2xi8>) -> memref<2x3xi8> {
    %0 = bufferization.to_tensor %arg0 : memref<3x2xi8>
    %1 = tosa.reshape %0 {new_shape = array<i64: 2, 3>} : (tensor<3x2xi8>) -> tensor<2x3xi8>
    %2 = bufferization.to_memref %1 : memref<2x3xi8>
    return %2 : memref<2x3xi8>
  }
}

Adding the --convert-func-to-llvm flag before using --ensure-debug-info-scope-on-llvm-funcseems to solve the problem. This ensures that function operations are first lowered to LLVM, which then allows the debug info subprogram attributes to be correctly materialized.

So, --ensure-debug-info-scope-on-llvm-func option can't be used alone? Should it be accompanied by some error handling instead of just throwing crash?
