--- Comment #2 from Rafael Avila de Espindola <rafael.espindola at gmail dot com> --- This is again visible on trunk now that pr62302 has been fixed (thanks!). It doesn't seem profitable to ever put D0 in the D5 comdat. It cannot be equal to D1 or D2, so putting it there just constrains the linker unnecessarily.
