{
RaiseSignalException is called from SignalConverter, once we've made things look
like there's a legitimate stack frame above us. Now we will just create
an exception object, and raise it via a software raise.
}
procedure RaiseSignalException(ExceptionEIP: LongWord; FaultAddr: LongWord; ErrorCode: LongWord);
begin
raise GetExceptionObject(ExceptionEIP, FaultAddr, ErrorCode);
end;

{
SignalConverter is where we come when a signal is raised that we want to convert
to an exception. This function stands the best chance of being called with a
useable stack frame behind it for the purpose of stack unwinding. We can't
guarantee that, though. The stack was modified by the baseline signal handler
to make it look as though we were called by the faulting instruction. That way
the unwinder stands a chance of being able to clean things up.
