I would have also thought it would be non-trivial (Julia uses LLVM and has some non-backwards compatible patches) but this paragraph intrigued me:
>> At the time of this writing, LLVM 10 was just released two hours ago. It will take days or weeks for it to become available in various system package managers. But you can already download a master branch build of Zig and play with the new features of Clang/LLVM 10. For example, improved RISC-V support!
I found this for LLVM 12 (released April 14) https://github.com/ziglang/zig/commit/5a3ea9beced660c9cc463b... https://github.com/ziglang/zig/commit/e248de93a07fd6a7f48581... https://github.com/ziglang/zig/commit/6a7f21d1b8ca5c082c804e... https://github.com/ziglang/zig/commit/1438c324a460789f1004a3...
Andrew seem to be following along their release pretty closely.
