Some of that will be glibc&#x27;s coverage of a much wider range of architectures and host OSes than musl (a very back-of-the-envelope wc -l suggests that somewhere between 20 and 25% of glibc code is in sysdeps&#x2F; or ports&#x2F;sysdeps&#x2F;), but that&#x27;s clearly not the only thing contributing to glibc being bigger.
