@lcheylus I already like the #FreeBSD build process. I'm curious what you want to improve. Good luck with the project!

@lcheylus Unless there’s already been significant effort I happened to miss, the first step will be fixing non-determinism bugs in Clang/LLVM.

My recommendation is to setup a bot that does a triple (or more) comparison of a Clang bootstrap result using various different hosts, e.g. Windows, macOS, Linux, FreeBSD on different host architectures. You want diversity of pointer values to ferret out iterators that are inadvertently relying on that order when processing optimizations.
