tools/virtio: replace "__auto_type" with "auto" (2025-12-08 15:32:15 -0800)
Argh... teaching declaration parser in sparse to handle that is going to be fun, especially since there are corner cases where gcc and clang do not agree, even with --std=c23 --pedantic...
Well, until sparse actually handles C23, this is just a macro. __auto_type is already in use.
Just anticipating the joy of getting declaration parser to deal with that properly - there's bunch of fun corner cases where this macro wouldn't cut it. Sure, the underlying semantics can be mapped onto __auto_type, but the actual syntax is bloody awful, especially when you mix the typedefs into it.
Speaking of other fun sparse stuff: __VA_OPT__ support needs to be added; I think I have it plotted down to reasonable details, will post in a day or two...
Yeah... the C committee even admitted they botched the spec; the intent was for it to work "exactly like gcc __auto_type"...
