Howard Hinnant b54f86aa9d Richard Smith: __int128 is a GNU keyword which clang 3.1 supports. This usage of it as an identifier will need to be renamed.

Howard Hinnant e59dbd7b82 I would really like to write the handlers in terms of C++11 atomics. This would give us the best performance, portablity, and safety tradeoff. Unfortunately I can not yet do that. So I've put the desired code in comments, and reverted the handler getters to the slower but safer legacy atomic intrinsics.

Howard Hinnant 4ac72dd982 I've moved __cxa_terminate_handler, __cxa_unexpected_handler and __cxa_new_handler from the public header cxxabi.h into the private header cxa_handlers.hpp. During this move I've also moved them from namespace __cxxabiapple into the global namespace. They are, and have always been extern C and so the namespace (or lack of it) does not affect their ABI. In general external clients should not reference these symbols. They are atomic variables and will be changing into C++11 atomic variables in the future. However for those few clients who really need access to them, their name, mangling, size, alignment and layout will remain stable. You just may need your own declaration of them. Include guards have been added to the private header cxa_exception.hpp. The private header cxa_default_handlers.hpp has been removed and the default handlers are now file-static. Include guards have been added to the private header cxa_handlers.hpp.

Dave Zarzycki d6533ccd48 Less lame "concurrency" support
These APIs aren't thread safe, but they're pretending to be. Let's at
least make the getter as fast as they can be. The setters are a lost
cause unless the API can be fixed.

Howard Hinnant 49f28b5a47 I had originally made the handler function pointers a static internal detail, not accessible to the outside world. I did this because they must be accessed in a thread-safe manner, and the library provides thread-safe getters and setters for these. However I am at least temporarily making them public and giving them the Apple-extension names. In the future these may disappear again, and I think that would probably be a good idea.

Howard Hinnant 089123e65f Remove a TODO regarding where some can_catch are implemented. I opted to make can_catch pure virtual in the top __shim_type_info, and have each sub-class implement its own. There are some repeated definitions, but they are trivial.

Howard Hinnant 2d6810fbd6 Quash a TODO related to catching pointer-to-member. These tests fail on my copy of gcc-4.2. But I believe the tests to be correct (and they pass for libc++abi). I've enquired on the C++ standards mailing list for a clarification in case I'm wrong. So far I've gotten one response that agrees with me.

2012-02-01 19:21:28 +00:00
Howard Hinnant 69a10f466b Removing a TODO: can_catch is fundamentally different than search_above_dst. can_catch is looking for an unamiguous public base class of a specific type, but at any address. search_above_dst is looking for an unambiguous public base class of a specific type, *and* at a specific address. Additionally can_catch is run for all types. search_above_dst is only run on class types. So these are only superficially similar. Not similar enough for resuse, at least without making the code unreadable.
