MLIR-based Vitis HLS LLVM Bridge

📥 🎯 MLIR toolchain to import and export Vitis HLS LLVM (.ll) files.

WARNING: This is a work-in-progress and will be actively changed.

This repository contains an MLIR-based toolchain that bridges Vitis HLS LLVM (.ll) files with MLIR workflow. It imports LLVM source code into the MLIR LLVM dialect and allows the generation of Vitis HLS-compatible LLVM outputs from the MLIR LLVM dialect. As a future work, it will raise the Vitis HLS pragmas and intrinsics into high level dialects.

How to Build

0. Clone MLIR-Vitis and install prerequisites

git clone https://github.com/heterosys/mlir-vitis.git
cd mlir-vitis

sudo apt-get install -y build-essential python3-pip
pip3 install cmake ninja psutil

1. Build MLIR-Vitis

cmake -S . -B build \
  -DCMAKE_BUILD_TYPE=Debug \
  -DCMAKE_MAKE_PROGRAM=ninja -G Ninja
cmake --build build --target all

This will build a modified version of LLVM.

To test MLIR-Vitis:

cmake --build build --target check-vitis

Cheers! 🍺
