Howard Hinnant 2c2b55f27f Change size of reference count field in __libcpp_nmstr from 32 bits to 64 bits for 64 bit targets. This is controls the data layout of all exceptions defined in <stdexcept>. This aligns the ABI with that of gcc-4.2.

Howard Hinnant 757640b156 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.

Howard Hinnant b2a9cee678 Erik Olofsson: This patch adds support for lambda demangling. I fixed this because it crashed lldb when it tried to demangle the added test.
Not sure how it should identify the lambda so that might need changing from the current 'lambdax'::  Howard:  Please patch CREDITS.TXT.

Howard Hinnant a8c5d770f9 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.

Howard Hinnant 95d917f8ee Andrew Morrow: The variable 't1' on line 10188 of cxa_demangle.cpp is uninitialized

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.
