MLIR Interpreter (Multi-Level Interpreter)

Out-of-Tree Interpreter for executing MLIR code. Based on work originally published by @lchien

Building

mkdir build && cd build
cmake -G Ninja -DLLVM_DIR=/opt/homebrew/opt/llvm@19/lib/cmake/llvm -DMLIR_DIR=/opt/homebrew/opt/llvm@19/lib/cmake/mlir -DCMAKE_EXPORT_COMPILE_COMMANDS=On -DCMAKE_BUILD_TYPE=RelWDebInfo ../ -DCMAKE_INSTALL_PREFIX=/opt/homebrew/opt/llvm@19

MacOS Build Example

brew install cmake ninja llvm@19
cmake -G Ninja -DLLVM_DIR=/opt/homebrew/opt/llvm@19/lib/cmake/llvm -DMLIR_DIR=/opt/homebrew/opt/llvm@19/lib/cmake/mlir -DCMAKE_EXPORT_COMPILE_COMMANDS=On ../

Testing

• mli executable takes in a .mlir file and runs the interpreter on it.

Example: build/src/mli <path-to-mlir-file> --args=5,10
