I would hope if llvm/clang is working you shouldn't see any additional breakage due to rust (I don't believe they overly hack llvm for their use). > So the bottom line should be that we'll be able to make it work, but there > is likely going to be more work since rust is less mature than C.

Absolutely. The aim of this exercise was to make sure downstreams are aware this is coming so it doesn't come as a surprise. I did CC emulation at freebsd but I got bounced as I was not subscribed. Could you make the wider FreeBSD community aware of the thread? > > Warner --=20 Alex Benn=C3=A9e Virtualisation Tech Lead @ Linaro
