--- Comment #4 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
it is pretty much completely broken also long before gcc-5:
typedef enum __attribute__((mode(QI))) e
{
e1 = 1,
e2 = 2
} ee;
ee x;
int y;
int test()
{
y=sizeof(x);
return x == e1;
}
in "C" sizeof(x) == 4, and test returns always(!) 0
in "C++" mode(QI) is simply ignored.
I think, that what I wanted can be done by
typedef enum __attribute__((packed))
{
e1 = 1,
e2 = 2
} ee;
which seems to work as expected in "C" and "C++".
It would be OK for me, if C and C++ would just emit an error if
the mode attribute is not supported.
