README.md

A set of (poorly-written) shell scripts to demonstrate building LLVM against musl.

This code is for demonstration purposes only; it should be used only as reference for cleaner build systems.

An explicit goal is to try to keep the CMAKE variables as explicit in the sources as possible.

This work is heavily derived and derived entirely from Saleem Abdulrasool's (@compnerd) gist.

Sysroot

Builds a sysroot that looks like:

sysroot
