Test app to generate LLVM IR

This demo C++ uses LLVM Core libs to generate a basic main function.

Building

• Install LLVM core libs to your system (llvm-dev package in Ubuntu) and update CMakeLists.txt file accordingly

• Run the following commands to build

    mkdir build
    cd build
    cmake ../
    make
  

• Generate IR and save

    ./codegen > main.ll 
  

• Compile and run LLVM IR. Then check return code

    clang main.ll -o main.out
    ./main.out
    echo $?
