Two changes: 1) I still didn't have the ABI correct to match the gcc-4.2 std::string under the exception classes. I think the changes to stdexcept.cpp have got that down now. 2) On Apple platforms I'm seeing visibility bugs in applications with respect to type_info's being hidden. This is causing dynamic_cast to malfunction because there are multiple type_info's running around for one type within an application, making dynamic_cast believe that one type is actually multiple types. As a stop gap measure I'm trying to detect this error, print out an error message, but continue with the most likely desired result. This is all under __APPLE__. This behavior can be expanded to other platforms if desired.

I've added Apple-only behavior that looks for libstdc++ in the same process and if found, checks the string stored in <stdexcept> exception objects to see if it is the gcc empty string singleton before manipulating the reference count. This is done so that if such an exception is created with a zero-length string in libstdc++, libc++abi won't try to delete the memory. This is part of a ongoing process to make libc++ exceptions ABI-compatible with libstdc++-4.2 exceptions, to the point that each library can catch exceptions thrown by the other. If other parties would also like this behavior, the #if __APPLE__ can be broadened.

Specifically disallow primary-expressions of the form LT_... on the basis of this decition: http://sourcerytools.com/pipermail/cxx-abi-dev/2011-August/002422.html . Failure to disallow this was causing infinite recursion in the demangler when these symbols show up due to mangling bugs. This patch causes the demangler to return an invalid mangled name result rather than crash in infinite recursion.

Fixes apple: #12020687 . This was a problem in the demangler with template

substitution forward references. That is, sometimes a mangled name refers to
a substitution that hasn't yet been defined. The demangler was derferencing a
null pointer in this case because it wasn't properly guarded against a
forward reference. Test case added to catch this problem.

Andrew Morrow: Mainline clang seems to have recently become more strict about the
...
consistent application of visibility attributes, which causes some new
breakage in libcxxabi:
In file included from src/libcxxabi/src/cxa_default_handlers.cpp:19:
src/libcxxabi/src/private_typeinfo.h:123:23: error: visibility does
not match previous declaration
class __attribute__ ((__visibility__(default))) __class_type_info
^
src/libcxxabi/src/private_typeinfo.h:19:13: note: previous attribute is here
#pragma GCC visibility push(hidden)
^
1 error generated.
The forward declaration of __class_type_info is picking up hidden
visibility from the #pragma, which conflicts with the default
visibility applied when the class is later fully declared. I'm
assuming that the full declaration has it right (and that the
diagnostic is correct), so the attached patch applies the default
visibility attribute to the forward declaration.

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.

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.

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.

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.

Add a descriptive name for a constant. Also I'm at least temporarily waging war on throw specs, both old and new style. Except where we have already publicly exposed the throw spec, I'm getting rid of them. They may come back later. But they seem somewhat prone to cyclic dependencies here. The throw spec implies compiler generated code that this library has to jump to during stack unwinding. I'd like to minimize the possiblity that the code used to properly make that jump is itself creating such jumps.

By changing all of the throw() specs to noexcept I've been able to compile and link all of the source files into a dylib. Prior to this substitution the changed functions were calling __cxa_call_unexpected which isn't implemented yet. However in none of these cases do we actaully want __cxa_call_unexpected to be called. Primative buildit script added.

Marshall Clow reminded me that fallback_malloc.cpp was broken out for testing purposes. We've agreed to simply rename fallback_malloc.cpp to fallback_malloc.ipp. Thanks Marshall.
