'func.func' is unknown

[kobeyu]

Hi
I rollback to commit 7feb80 for onnx to hls, but scalehls-opt shows the error message:

lenet.onnx.mlir:14:3: error: custom op 'func.func' is unknown
func.func @main_graph(%arg0: memref<1x3x32x32xf32>) -> memref<1x10xf32> attributes {input_names = ["input.1"], llvm.emit_c_interface, output_names = ["18"]} {

may I ask which commit of onnx-mlir and llvm(mlir for onnx-mlir) should I use for onnx model?
