+# Reid-LLVM
+Attempt at re-creating Reid, this time using LLVM.
+
+## Various notes in order to get this working properly
+This is what worked for me, might not (probably) work for you, depending on
+various versions of various libraries.
+
+### Compiling LLVM 16.0.0
+
+#### Context
+Context for my computer. I am on ArchLinux, and here are some libraries and
+their current versions that I have installed as of compiling, I'm not sure what
+of them are relevant, if any, but saving them here still feels like a good idea
+for the future:
+- `cmake 3.27.0-1`
+- `lib32-llvm-libs 15.0.7-1`
+- `llvm 15.0.7-3`
+- `llvm-libs 15.0.7-3`
+- `gcc 13.1.1-2`
+- `gcc-libs 13.1.1-2`
+- `lib32-gcc-libs 13.1.1-2`
+- `lld 15.0.7-2`
+- `lldb 15.0.7-3`
+- `clang 15.0.7-9`
+- `make 4.4.1-2`
+- `automake 1.16.5-2`
+
+#### Commands
+
+```sh
+wget https://github.com/llvm/llvm-project/releases/download/llvmorg-16.0.0/llvm-16.0.0.src.tar.xz
+wget https://github.com/llvm/llvm-project/releases/download/llvmorg-16.0.0/cmake-16.0.0.src.tar.xz
+
+tar xvf llvm-16.0.0.src.tar.xz
+tar xvf cmake-16.0.0.src.tar.xz
+
+mv cmake-16.0.0.src cmake
+
+cd llvm-16.0.0.src
+
+cmake -B build -DCMAKE_INSTALL_PREFIX=$HOME/llvm-16 -DCMAKE_BUILD_TYPE=MinSizeRel -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_INCLUDE_TESTS=OFF
+
+make -j8
+```
+
+*Also Note:* Building LLVM with `Ninja` was not successful for me, but this
+method was. Ninja may be successful with you, to try it, add `-G Ninja` to the
+`cmake`-command, and instead of `make` run `ninja install`.
+
+### Building this crate itself
+
+Assuming `llvm-16.0.0.src` from the previous step was at
+`/path/llvm-16.0.0.src`, building this crate can be done via the following command:
+
+```sh
+LLVM_SYS_160_PREFIX=/path/llvm-16.0.0.src/build cargo build
+```
+
+## In conclusion
+Good luck! It took me a good 10 hours to figure this out for myself, I sure hope
+these instructions help both myself and someone else in the future!
