First, that just isn't how ELF works. ELF has a very simple model: everything simply works correctly without source code annotation, and symbol interposition works. You are looking for a more complex model at the cost of adding source code annotations. That's not crazy, but it's not ELF. Second, I still don't understand how you can have position independent code on 32-bit x86 which accesses global variables but does not use a GOT. > This is basically the Win32/NT model and seems pretty good. The model is good until you need to use symbol interpositioning. Symbol interpositioning is not a bizarre technique that nobody uses. People use it regularly to, e.g., use debugging malloc code, or to add profiling timers to all network accesses. Ian
