Return statement will never be executed warning

Question

I've recently come across with double return statement (one of them was added by mistake) in our project and wondering why compiler doesn't show a warning for that?!

Ok, I added -Wunreachable-code to other warning flags, but still no luck.

Got warning - with a code to execute after return statement:

Didn't get warning but still second return statement will never be executed.

Even if I add something like this, still no warning

Is there extra warning flag for that, or compiler isn't smart enough?

Answer 1

Good catch!

-Wunreachable-code does not report a warning and there is no other warning flag which would do.
Not even the Static Analyzer catches this mistake!

(Tested with XCode 6.1 GM 2)

Answer 2

Wrap your code in pragma flags that will suppress that warning between the push and pop

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunreachable-code"
//Your code goes here
#pragma GCC diagnostic pop
