theraven	bd73cc4e57	Added run-time abort if the first ivar of a newly-loaded class does not immediately follow on from the previous one. This (hopefully, modulo some potential weirdness related to bitfields) means that we should now get programs refusing to start in most cases where they depend on frameworks that had their ABI change but didn't bump the library version. This seems preferable to the previous behaviour of corrupting memory (note that this won't catch the case where the superclass has its ivars rearranged, but remains exactly the same size and the subclass references the ivars).	16 years ago
theraven	f8b98a73a2	Bug fixes in libobjc2: - nil_method now returns 0, not receiver. - Metaclasses actually get their dtables installed with the new ABI. For some reason this wasn't being done, so class messages didn't work with the new ABI. Now they do and (at least some) nontrivial programs work. - Undid commenting out of the code setting the fast ivar access pointers. I can't remember why this was commented out, but it seems not to break anything. I have an LLVM pass that makes compiled code access these pointers, but it's not committed yet.	16 years ago
