theraven	6317b79a10	Implemented the new exception ABI, and a load of tests for it. This is used by clang trunk if -fobjc-runtime-1.7 is specified and provides significantly better interoperability with foreign exceptions. Note: Most of the exception tests will not pass with gcc or clang < 3.3. They test things that are impossible to implement quite correctly with the GCC-compatible exception ABI. Also updated the release notes to reflect recent improvements.	13 years ago

theraven	26784adc0a	Fix some warnings. Remove the dependency on <typeinfo> containing the vtable layout for std::type_info. This allows libobjc2 to be built against libc++ and libcxxrt and still provide working a unified exception model. Note: This is broken on FreeBSD < 9.1, because it ships a libsupc++ with a broken ABI.	14 years ago
theraven	600e970dea	Separate ObjC++ support out into libobjcxx. Now code that doesn't need ObjCXX support can safely ignore it again.	15 years ago
theraven	62536ce247	Added more header comments.	15 years ago
theraven	e0719a9c62	Added Objective-C++ exception handling support. Allows throwing Objective-C objects with throw or @throw and catching them with catch() or @catch.	15 years ago
