I do not see this with tip of tree LLVM. It seems this was only recently
supported in the integrated assembler:

https://github.com/llvm/llvm-project/commit/b65e0947cade9bd39036a7700b54c1df4ec00756

If it is not easy to work around, we can probably just leave it broken
and tell anybody who notices to upgrade their compiler.

Cheers,
Nathan

I wrapped my head around it today, but no idea how to solve it...

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]

-- or suchlike, I suppose.  Someone just needs to fill `vvv' in.

Given this file is unconditionally compiled, we would be better served
just adjusting min-tool-version.sh to show an error during configuration
time. Technically, this is only needed with LLVM_IAS=1 but that is the
default and adjusting as-version.sh to check the version would be a
little difficult but I will try to think about it more in the next few
days.

Cheers,
Nathan
