Well, whether it's a bug or missing feature can be rather subjective.
Likewise it can be argued whether it is correct to do a test with
-march=foo and assuming the result of that test carries over to the
I'll try to implement it for upcoming versions of llvm in any case.

Sure, if you regard it as a hack, yes.

Yes, that seems to be true, sorry about that. Now I've tested it with GCC
and fixed the trivial bugs in this patch, and now the deinterlace plugin

If that stands, then fine, so be it. I'll post the updated and fixed patch
in any case, if other downstreams want to carry it meanwhile.
