...015 about opaque pointers. Aside from using the new methods (e.g. LLVMBuildGEP2), is there any other way to perpare for this change? And also - is it possible to use something like opaque pointers (that is using a single pointer type) even before the switch has been flipped in LLVM? Christoffer AEGIK / www.aegik.se

The advantages: 1. A pointer to the struct offset can be converted to a pointer without any cost. 2. A nullpointer to a stretchy buffer can be treated as a zero length array. Consequently no actual struct allocation is needed to represent a zero length array. 3. A reference to the array is the same size as to a pointer. 4. It can be converted to and back from an pointer without losing any

There’s no getting around having one’s own type hierarchy. >> And also - is it possible to use
