An out-of-tree dialect template for MLIR

This repository contains a template for an out-of-tree MLIR dialect as well as a standalone opt-like tool to operate on that dialect.

How to build

This setup assumes that you have built LLVM and MLIR in $BUILD_DIR and installed them to $PREFIX. To build and launch the tests, run

mkdir build && cd build
cmake -G Ninja .. -DMLIR_DIR=$PREFIX/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$BUILD_DIR/bin/llvm-lit
cmake --build . --target check-standalone-opt

To build the documentation from the TableGen description of the dialect operations, run

cmake --build . --target mlir-doc

Note: Make sure to pass -DLLVM_INSTALL_UTILS=ON when building LLVM with CMake so that it installs FileCheck to the chosen installation prefix.
