Simple Compiler

A toy compiler handwritten in a weird subset of C++.

The language is a staticly typed, low-level systems programming language. It is compiled to an internal IR, then LLVM is used to generate native machine code.

The compiler currently requires clang for compiling the runtime/bootstrap code and lld for linking.

The compiler also includes a profiler (for the compiler itself) that can be enabled with the -DPROFILING=Yes option given to CMake. The profiler trace logs are viewable with speedscope. The profiler currently only works on Windows and x86.

Building

1. Install LLVM 11 or higher (including clang and lld)
2. Install CMake 3.21 or higher
3. Install target development depndencies
   • (Windows) Install the Windows SDK (Only tested on Windows 10)
   • (Linux) No development libraries are needed
   • (Emscripten) Install the Emscripten SDK
4. Clone repository

   git clone https://github.com/yaram/simple-compiler.git
   cd simple-compiler

5. Run CMake configuration

   mkdir build
   cd build
   
   cmake ..

6. Run build

   cmake --build . --target compiler
