Except for saving memory in *very* specific case (a structure allocated tens of

Even then, 'uint32_t flags' can be just as easy to use as unsigned foo:1,
bar:1, etc:1.
Plus you get knowledge of the actual structure layout, which is presumably
important
*because* it's allocated millions of times.

Do we have a specific API (or set of macros) in QEMU to help with this?
If yes, maybe I could mention it in the doc ("we recommend using X
instead of bitfields").
