Hi,
i have issue with build on FreeBSD 13.1

FreeBSD clang version 13.0.0 (git@github.com:llvm/llvm-project.git llvmorg-13.0.0-0-gd7b669b3a303)
Target: x86_64-unknown-freebsd13.1

Unfortunately, the non-linux ports are wofully out of date from the rest of the code base and currently have no expectation of compiling.

I do plan to eventually get non-linux ports working again, but it just hasn't been a priority in a bit. But perhaps you've motivated me to spin up a FreeBSD VM again and see what we can do ;-)

[Martinfx]

good idea, i can help with test

[arrowd]

I took a quick look on the FreeBSD plugin and it is extremely out of sync with the rest of the code base. Would you accept a PR that at least makes the plugin compile by stubbing out actual implementations?

[eteran]

Absolutely! any help on this front is welcome :-)
