Missing warning for no return statement in function returning non-void
The following code when compiled with -Wreturn-type -c
prints a warning about function test2 which is a non-void function missing a
return statement, but it does not print a warning about test1.
tmp.C: In function `int test2()':
tmp.C:17: warning: control reaches end of non-void function
If I comment out both lines in test1, I then get both warnings:
tmp.C: In member function `int foo::test1()':
tmp.C:10: warning: no return statement in function returning non-void
tmp.C: In function `int test2()':
tmp.C:17: warning: control reaches end of non-void function
///////////////////////
int xxx = 999;
class foo
{
public:
int test1()
{
if (xxx == 10)
return 0;
}
};
int test2()
{
if (xxx == 10)
return 0;
}
///////////////////////
I need it to warn about test1.
