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
undefined if an exception is thrown through the compiled functions.
You must use
--exceptions, if you want exceptions
to propagate correctly though C functions.
