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

Building

DEVELOPER NOTE: If you end up seeing weird issues when making changes to this code be aware that it may be linking against the installed version of the headers. To fix this, make sure to remove the installed headers and re-run the build process

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
