A stable onnx-mlir version for LLVM 16.0.6

[MisGreee]

I'm in the process of developing my own AI compiler, leveraging LLVM version 16.0.6. I've attempted to build onnx-mlir versions 0.4.1 and 0.3.2, but I've encountered issues with both. Is there a stable version available for it?

my build command:

cmake -G Ninja -DCMAKE_C_COMPILER=clang-16 -DCMAKE_CXX_COMPILER=clang++-16 -DLLVM_ROOT=/usr/local/llvm -DMLIR_DIR=/usr/local/llvm/lib/cmake/mlir/ ..

onnx-mlir builds with specific commits of LLVM. It is unlikely you will get onnx-mlir to work without building LLVM from source and on a specific commit.

The instructions can be found here https://github.com/onnx/onnx-mlir/blob/main/docs/BuildOnLinuxOSX.md.

In short, the answer to your question is no.

thanks for your help. from what you mentioned, it seems challenging to compile onnx-mlir as a third-party library instead, it's better suited as a standalone binary.

@MisGreee I think that is a fair assessment.

MLIR itself isn't very stable, which is a large part of why its hard to restrict ourself to a stable version. It would be too restrictive to development of the repo.

We do update LLVM every two weeks. You can see the schedule here https://github.com/onnx/onnx-mlir/wiki/LLVM-Update-Schedule. And the commit isn't totally random. We try and sync with the same commit that torch-mlir, and hlo use.

I know that doesn't help your situation. I just wanted to add some context in case you were curious.

The LLVM versioning is a nightmare that I think everybody suffers from, and deals with in the their own way unfortunately.

outstanding and inspiring work 👍
