LLVMCMakeBackend

An LLVM backend to CMake, you can compile C++/Rust into CMake now!

Well, this is a stupid project, but implementing it is a funny experience, and it is a challenge that implements LLVM IR in a restricted environment.

Building

This project depends on LLVM 13. So installing it first is needed, by apt install llvm-13-dev (add llvm apt source first) or building them yourself. Then run

mkdir build && cd build
cmake .. && cmake --build . --parallel

Usage

Run ./LLVMCMakeBackend Test.ll, and if there are no errors, Test.ll.cmake will be generated. It can be run by cmake -P Test.ll.cmake, and can be included in some CMake script.

Hacking

The most of codes you may be interested in are located in lib folder. The codes in cli folder belong to the cli part, and not very valuable.
