to force gcc to emit additional warnings about unhandled exceptions

[adaslaw]

Hi

Is it possible to force gcc (or xlc) compiler to emit compilation
warning or compilation error for such code:

void fooA() throw (MyException)
{
...
throw MyException();
...
}

void fooB() throw()
{
fooB();
}

I would like to be warned that in function fooB:
* there is no appropriate catch block to catch MyException from fooA
.... or ...
* fooB should be declared as: void fooB() throw(MyException)

Any idea to force the compiler to emit such warnings?

Kind regards,
Adam

This is a compiler-specific question and should be asked in the
newsgroup dedicated to that compiler. Tool invokation is not
on topic here. This is a language newsgroup.

No. "throw()" guarantees absolutely that the function will
never exit via an exception. §15.4/8,9:

I'm not sure what I was thinking when I said otherwise, but you're
obviously correct.

An earlier draft of the standard? I too seem to recall having
seen something similar---that regardless of the exception
specification, std::bad_exception could propagate. I wasn't the
only one, however, who found it totally unacceptable, and it
didn't make it into the final version of the standard.
