2.1.64 --exceptions, --no_exceptions
This option enables or disables exception handling.
In C++, the --exceptions option enables the use of throw and try/catch, causes function
exception specifications to be respected, and causes the compiler to emit unwinding
tables to support exception propagation at runtime.
In C++, when the --no_exceptions option is specified, throw and try/catch are not
permitted in source code. However, function exception specifications are still parsed,
but most of their meaning is ignored.
In C, the behavior of code compiled with --no_exceptions is undefined if an exception
is thrown through the compiled functions. You must use --exceptions, if you want
exceptions to propagate correctly though C functions.
Default
The default is --no_exceptions. However, if you specify an ARM Linux configuration
file on the command line and you use --translate_g++, the default changes to
--exceptions.

2.1.65 --exceptions_unwind, --no_exceptions_unwind
This option enables or disables function unwinding for exception-aware code. This
option is only effective if --exceptions is enabled.
When you use --no_exceptions_unwind and --exceptions then no exception can
propagate through the compiled functions. std::terminate is called instead.
