A simple imperative language with indentation-specific syntax, functions, control-flow and jit-based compilation using C++, LLVM, Bison and CMake.

Building LLVM for this project requires RTTI for the cl::opt library and -j1 during install to prevent memory running out on WSL. Zlib is for lldb usage.

cmake -S llvm -B build -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_PROJECTS="clang;lldb;lld" -DLLVM_ENABLE_RTTI=ON -DLLVM_ENABLE_ZLIB=ON
ninja -C build -j1 install

Built using LLVM 19

mkdir build
cd build
cmake ..
make && ./jitCalc
