B.13 Language support library
Describes implementation-defined aspects of the Arm® C++ compiler and C++ library relating to the language support library, as required by the ISO C++ Standard.
- Exit status (18.5).
- Control is returned to the host environment using the
_sys_exitfunction of the Arm C Library. - Returned value of
std::bad_alloc::what(18.6.2.1). - The returned value is
std::bad_alloc. - Returned value of
std::type_info::name(18.7.1). - The returned value is a string containing the mangled name of the type that
is used in the
typeidexpression. The name is mangled following the Itanium C++ ABI specification. - Returned value of
std::bad_cast::what(18.7.2). - The returned value is
std::bad_cast. - Returned value of
std::bad_typeid::what(18.7.3). - The returned value is
std::bad_typeid. - Returned value of
std::bad_exception::what(18.8.1). - The returned value is
std::bad_exception. - Returned value of
std::exception::what(18.8.1). - The returned value is
std::exception. - Use of non-POFs as signal handlers (18.10).
- Non Plain Old Functions (POFs) can be used as signal handlers if no
uncaught exceptions are thrown in the handler, and the execution of the
signal handler does not trigger undefined behavior. For example, the signal
handler may have to call
std::_Exitinstead ofstd::exit.
