# LLVM port for SerenityOS
This folder contains the SerenityOS port of LLVM/Clang. Right now it builds LLVM, Clang, lld and compiler-rt.
To compile programs it is recommended to install the GCC port because Clang is not able to use lld yet,
that's why GNU ld should be used.

# Patches for LLVM on SerenityOS
## `remove-wstring.patch`
Removes `wstring`s from the source code, as SerenityOS doesn't support them yet.
## `insert-ifdef-serenity.patch`
This patch adds several defines in order to omit things not supported by SerenityOS.
