Alex Zinenko 176379e0c8 [mlir] Use the interface-based translation for LLVM "intrinsic" dialects Port the translation of five dialects that define LLVM IR intrinsics (LLVMAVX512, LLVMArmNeon, LLVMArmSVE, NVVM, ROCDL) to the new dialect interface-based mechanism. This allows us to remove individual translations that were created for each of these dialects and just use one common MLIR-to-LLVM-IR translation that potentially supports all dialects instead, based on what is registered and including any combination of translatable dialects. This removal was one of the main goals of the refactoring. To support the addition of GPU-related metadata, the translation interface is extended with the `amendOperation` function that allows the interface implementation to post-process any translated operation with dialect attributes from the dialect for which the interface is implemented regardless of the operation's dialect. This is currently applied to "kernel" functions, but can be used to construct other metadata in dialect-specific ways without necessarily affecting operations.

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.
