Previously we allowed these casts only for constants declared in system headers, which we assume are retain/release-neutral. Now also allow them for constants in user headers, treating them as +0. Practically, this means that we will now allow: id x = (id)kMyGlobalConst; But unlike with system headers we cannot mix them with +1 values: id y = (id)(b ? kMyGlobalConst : [Obj newValAtPlusOne]); // error id z = (id)(b ? kSystemGlobalConst: [Obj newValAtPlusOne]); // OK Thanks to John for suggesting this improvement. llvm-svn: 230534
