2008-08-23 Paolo Carlini <paolo.carlini@oracle.com>
* testsuite/lib/libstdc++.exp (check_v3_target_atomic_builtins): Add.
* testsuite/lib/dg-options.exp (dg-require-atomic-builtins): Likewise.
* testsuite/18_support/exception_ptr/current_exception.cc: Use it.
* testsuite/18_support/exception_ptr/rethrow_exception.cc: Likewise.
* testsuite/18_support/exception_ptr/lifespan.cc: Likewise.
2008-08-23 Sebastian Redl <sebastian.redl@getdesigned.at>
Add (again) exception propagation support as per N2179. Feature is
available only when _GLIBCXX_ATOMIC_BUILTINS_4 is defined.
* libsupc++/exception_ptr.h (exception_ptr, current_exception,
copy_exception, rethrow_exception): New file, implement exception
propagation.
* libsupc++/eh_ptr.cc (exception_ptr, current_exception,
rethrow_exception, __gxx_dependent_exception_cleanup): Likewise.
* libsupc++/unwind-cxx.h (__cxa_exception): Add reference count.
(__cxa_dependent_exception, __cxa_allocate_dependent_exception,
__cxa_free_dependent_exception, __get_dependent_exception_from_ue,
__GXX_INIT_DEPENDENT_EXCEPTION_CLASS, __is_dependent_exception,
__gxx_dependent_exception_class, __get_object_from_ue,
__get_object_from_ambiguous_exception): Add.
(__GXX_INIT_EXCEPTION_CLASS, __gxx_exception_class): Rename.
(__is_gxx_exception_class): Handle dependent exceptions.
* libsupc++/eh_arm.cc (__cxa_type_match): Likewise.
* libsupc++/eh_call.cc (__cxa_call_unexpected): Likewise.
* libsupc++/eh_personality.cc (__gxx_personality_*): Likewise.
* libsupc++/eh_type.cc (__cxa_current_exception_type): Likewise.
* libsupc++/eh_alloc.cc (__cxa_allocate_dependent_exception,
__cxa_free_dependent_exception): Add.
* libsupc++/eh_throw.cc (__gxx_exception_cleanup): Handle reference
counting.
* libsupc++/exception: Conditionally include exception_ptr.h.
* libsupc++/Makefile.am: Register new files.
* libsupc++/Makefile.in: Regenerate.
* config/abi/pre/gnu.ver: Add new symbols.
* testsuite/18_support/exception_ptr/current_exception.cc: Test the
core functionality of current_exception().
* testsuite/18_support/exception_ptr/rethrow_exception.cc: Test the
core functionality of rethrow_exception().
* testsuite/18_support/exception_ptr/lifespan.cc: Test the life span of
exception objects during exception propagation.
