--- Comment #2 from Oleg Endo <olegendo at gcc dot gnu.org> ---
There is a funny work around for this though ...
#include <cstdint>
struct bswapped16
{
const uint16_t val;
constexpr bswapped16 (uint16_t v) : val (__builtin_bswap16 (v)) { }
};
constexpr uint16_t bswap16 (uint16_t x)
{
return bswapped16 (x).val;
}
enum { foo_4 = bswap16 (1) }; // OK
