A separate change for documentation purposes. Test-case: void func(void) { struct UNDEFINED x; x.member = 0; } output: 1:6 def f func void ( ... ) 3:26 func def . v x struct UNDEFINED 4:9 func -w- . v x struct UNDEFINED 4:10 func -w- . m UNDEFINED.member bad type but in this case is_sym_local(UNDEFINED) = F makes more sense, most probably this struct was defined somewhere else but __sparse() didn't see its definition. Change lookup_member() to set type->scope = file_scope if !symbol_list. This is not 100% correct, but struct_union_enum_specifier() does the same check with the following comment: // The following test is actually wrong for empty // structs, but (1) they are not C99, (2) gcc does // the same thing, and (3) it's easier.
