Bit-fields

Bit-fields are not implemented. VisitFieldDecl ignores the declared width, so a field such as unsigned flags : 3; is emitted as a plain u32 field: the struct compiles, but its layout, size, and the wrap-around of the field’s value differ from C.

Warning

Code that relies on bit-field layout or width (packing several fields into one word, sizeof on such a struct, storing a value wider than the field) translates silently to something else (#312).
