Invoke `keep()` on the output file of `mlir-opt` in case the invocation of `MlirOptMain` was successful, to make sure the output file is not deleted on exit from `mlir-opt`. Fixes a similar problem in `standalone-opt` from the example for an out-of-tree, standalone MLIR dialect. This revision also adds a missing parameter to the invocation of `MlirOptMain` in `standalone-opt`. Differential Revision: https://reviews.llvm.org/D77643 |

An out-of-tree MLIR dialect
This is an example of an out-of-tree MLIR dialect along with a standalone opt-like tool to operate on that dialect.
Building
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
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.
