one more testcase that renders different warning.
typedef enum { X, Y } e;
e zoo( e __e )
{
e r;
switch ( __e )
{
case X: r = Y; break;
case Y: r = X; break;
}
return r;
}
bug.cpp: In function 'e zoo(e)':
bug.cpp:4: warning: 'r' may be used uninitialized in this function
e zoo(e) (__e)
{
e r;
e D.2076;
int __e.0;
<bb 0>:
switch ((int) __e)
{
case 0: goto <L0>;
case 1: goto <L6>;
default : goto <L5>;
}
<L6>:;
r = 0;
goto <bb 3> (<L2>);

return r;
}
