I have:
main.cpp: In function 'QString parityToString(ParityType)':
main.cpp:312: warning: control reaches end of non-void function
When:
enum ParityType
{
PAR_NONE,
PAR_ODD,
PAR_EVEN,
PAR_MARK, //WINDOWS ONLY
PAR_SPACE
};
And my function:
QString parityToString(ParityType value)
{
switch(value)
{
case PAR_NONE:
return "none";
case PAR_ODD:
return "odd";
case PAR_EVEN:
return "even";
case PAR_MARK:
return "mark";
case PAR_SPACE:
return "space";
}
}

Can you provide a preprocessed testcase?

My test case:
enum ParityType
{
PAR_NONE,
PAR_ODD,
PAR_EVEN,
PAR_MARK, //WINDOWS ONLY
PAR_SPACE
};
QString parityToString(ParityType value)
{
switch(value)
{
case PAR_NONE:
return "none";
case PAR_ODD:
return "odd";
case PAR_EVEN:
return "even";
case PAR_MARK:
return "mark";
case PAR_SPACE:
return "space";
}
}

> My test case:
That testcase is not compilable at all. Can you use -save-temps and provide
the preprocessed source (which is the .ii file that is generated)?

The URL for preprocessed source gives a 404 now.
The enum has a range 0-7 and if you call parityToString(ParityType(5)) then
control falls off the end of the function, so the warning is correct.
