This project aims to create soda-opt, a tool that leverages mlir to extract,
optimize, and translate high-level code snippets into LLVM IR,
so that they can be synthesized by our high-level synthesis tool of choice.
As a long term vision, the SODA-OPT project seeks to provide a set of
compiler libraries to perform the target optimizations; runtime libraries
to offload the compute from host to the selected targets; and to be
standalone, being built on top of standard mlir tools and dialects, so
that any project (e.i. TF, ONNX, etc) could use the exposed optimization
passes to offload and perform HLS of selected code snippets. As a final
goal, soda-opt could later be merged into the main llvm-project codebase.
Pull our production image on dockerhub:
And follow one of our tutorials here.
This setup assumes that you have built LLVM and MLIR in $BUILD_DIR and
installed it to $PREFIX.
The current version of this project was tested with llvm-project commit:
339a7687e1c036a5f91c9d5391523b93e2e76cd3.
Make sure you have the correct commit checked-out.
Note: Make sure to pass -DLLVM_INSTALL_UTILS=ON when building LLVM/MLIR
with CMake so that it installs FileCheck.
To build soda-opt and run the tests of this project, execute:
mkdir build && cd build
cmake -G Ninja .. \
-DLLVM_EXTERNAL_LIT=$BUILD_DIR/bin/llvm-lit \
-DMLIR_DIR=$PREFIX/lib/cmake/mlir
# Run tests
cmake --build . --target check-sodaLLVM can be built with the helper build_tools/build_llvm.sh.
# To configure, build, and install
./build_llvm.sh <path/to/llvm/src> <llvm_build_dir> <llvm_install_dir>Alternatively it is possible to use the helper script
build_tools/build_soda.sh to build this project:
# To configure, build, and install
./build_tools/build_soda.sh <source_dir> <install_dir> <build_dir> <path/to/llvm/build/dir> <path/to/llvm/install/dir>To build the documentation from the TableGen description of the dialect operations, run:
cmake --build . --target mlir-doc
