How to revert LLVM to older version on LINUX?

I have installed LLVM on my WSL.But Now I need an older version of LLVM. How can I revert LLVM to old version? the commands I used to install it:

git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm
make

And my llvm-as --version outputs:

LLVM (http://llvm.org/):
  LLVM version 11.0.0git
  DEBUG build with assertions.
  Default target: x86_64-unknown-linux-gnu
  Host CPU: skylake

Can I just remove the dir build?

The llvm-project repository contains tags for almost every LLVM release. Just checkout them using git:

cd llvm-project
git checkout -t origin/llvmorg-3.8.0

It is advised to remove build dir and configure&build from scratch.
