BitFusion_using_MLIR

This is the project repository for ECE 663 (Spring 2023) at Purdue University.

To run this example first install llvm and MLIR following the instructions here: https://mlir.llvm.org/getting_started/

Add the LLVM build directory path to $LLVM_BUILD_DIR

The diirectory structure for bitfusion/ is as follows: bitfusion-opt/ -> The bitfusion opt tool is created here and the available dialects (works) and passes (nopt working) are registered. bitfusion-translate/ -> Not used as I did not register any new translations. include/ -> contains the table gen and include files (.h) for the dialect and conversion passes. lib/ -> contains the C++ files that define the passes test/ -> Contains the examples used when check-bitfusion is run. The examples can be tried out with $BITFUSION_BUILD_DIR/bitfusion-opt $PATH_TO_FILE

An out-of-tree MLIR dialect

This is an example of an out-of-tree MLIR dialect along with a bitfusion opt-like tool to operate on that dialect. This is based on the standalone dialect example provided with mlir.

Building

To build and launch the tests, run

cd bitfusion
mkdir build && cd build
cmake -G Ninja .. -DMLIR_DIR=$LLVM_BUILD_DIR/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$LLVM_BUILD_DIR/bin/llvm-lit
cmake --build . --target check-bitfusion

Should Pass 7 tests and fail 1.

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 in order to install FileCheck to the chosen installation prefix.
