For me, I think so.

We ran into this in IWYU [1], and I don't think inline assembly would
introduce a "use" of any significance...

I'm not sure what you mean by "soft error", but I think I'd just
ignore it completely rather than spewing diagnostics for things we
can't affect and don't really care about.

We don't use libclang, the problem is a little different there, as
they can't initialize the respective targets. Our current workaround
solves the problem for us.

Thanks!
