llvm 8 install size

I recently compiled llvm from source since I wanted to look at 8. However, it is a whooping 56G in size once installed. That seems excessive. How can I reduce the size of the installation? ; du -h -d 1 -c . 41M ./include 22G ./lib 35G ./bin 264K ./share 28K ./libexec 56G . 56G total Build using: cmake3 -G Ninja -DCMAKE_INSTALL_PREFIX=~/llvm -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=1 -DLLVM_ENABLE_PROJECTS="all" ../llvm
