An out-of-tree MLIR dialect
This is an example of an out-of-tree MLIR dialect along with a standalone
-like tool to operate on that dialect.
Building - Component Build
This setup assumes that you have built LLVM and MLIR in
and installed them to
. To build and launch the tests, run
mkdir build && cd buildcmake -G Ninja .. -DMLIR_DIR=$PREFIX/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$BUILD_DIR/bin/llvm-litcmake --build . --target check-standalone
To build the documentation from the TableGen description of the dialect operations, run
cmake --build . --target mlir-doc
Note: Make sure to pass
when building LLVM with CMake in order to install
to the chosen installation prefix.
Building - Monolithic Build
This setup assumes that you build the project as part of a monolithic LLVM build via the
mechanism.
To build LLVM, MLIR, the example and launch the tests run
mkdir build && cd buildcmake -G Ninja `$LLVM_SRC_DIR/llvm` \ -DCMAKE_BUILD_TYPE=Release \ -DLLVM_TARGETS_TO_BUILD=host \ -DLLVM_ENABLE_PROJECTS=mlir \ -DLLVM_EXTERNAL_PROJECTS=standalone-dialect -DLLVM_EXTERNAL_STANDALONE_DIALECT_SOURCE_DIR=../cmake --build . --target check-standalone
