What is the end goal of this?

I'm kind of unsure why do you care about which editor I use to
generate my code, that's up to the developer.

assembly (gas), python, perl, shell, Makefile, bison, flex, ocaml,
go...

Likely more that I've missed.

I do use an LLVM based toolstack, so that's usually latest LLVM import
on FreeBSD.  We do also test this on the cirrus-ci, see:

https://github.com/royger/xen/runs/5334480206

I_n any case I think the scope to some of the questions is unknown,
it's not feasible to expect to list every possible combination of
Linux versions vs Xen version vs whatever guests versions a given
developer might be running.
