--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
These days we get:
_1 = (unsigned long) &__bss_end1;
_7 = _1 + 18446744073709551615;
_6 = (unsigned long) &__bss_start1;
_11 = _7 - _6;
_12 = _11 >> 3;
_13 = _12 + 1;
_14 = _13 * 8;
__builtin_memset (&__bss_start1, 0, _14); [tail call]
Or
((((end - 1) - start) >> 3) + 1) * 8
In theory (I think) we could do:
(end - start + 7) & -8
