LLVM-18-Tutorials

This repository is an updated version of LLVM-11-Tutorials, where you can find a more detailed overview of the project.

Here I mainly record the differences between LLVM-11 and LLVM-18. The concrete changes are documented inside each experiment folder.

I’m happy to discuss—suggestions are welcome (jgeab@connect.ust.hk). If you find this repository useful, a star would be appreciated.

Before Running the Experiments

Auxiliary File Settings: To avoid potential warnings from VS Code, it is recommended to set the configurations in c_cpp_properties.json as follows:

• includePath:
  • ${workspaceFolder}/\*\*
  • /usr/local/include/
• cStandard: c17
• cppStandard: c++17

CMake Path: The compilation logic can be complex within these folders. Here is an explanation:

• The pass source codes can be found within the Implementations folder.
• The specific experiments testing each pass can be found in the Tests folder.
• The compiled libraries can be found in Tests/LLVM_Learner_Libs. Remember to include the corresponding passes in the relevant CMake files.
• The App folder contains the main pass-debugging benchmarks.
• The HLS_Data_Lib provides the timing and resource data needed for Light-HLS’s early-stage QoR estimation.
