## Installing LLVM, Python, Zig, and valgrind
To build the compiler, you need these installed:
* `libunwind` (macOS should already have this one installed)
* `libc++-dev` and `libc++abi-dev`
* Python 2.7 (Windows only), `python-is-python3` (Ubuntu)

* LLVM, see below for version

For debugging LLVM IR, we use [DebugIR](https://github.com/vaivaswatha/debugir). This dependency is only required to build with the `--debug` flag, and for normal developtment you should be fine without it.
