--- Comment #17 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed in GCC 7 by r7-1935.
On the gimple level we get:
<bb 3> [local count: 536870913]:
_2 = pretmp_31 + 2;
s_19(D)->p = _2;
goto <bb 5>; [100.00%]
<bb 4> [local count: 536870913]:
_11 = pretmp_31 + 4;
s_19(D)->p = _11;
_12 = MEM[(short unsigned int *)pretmp_31 + 2B];
_13 = (int) _12;
_23 = _13 << 8;
_14 = (unsigned int) _23;
_15 = _14 + _28;
<bb 5> [local count: 1073741824]:
# _6 = PHI <_28(3), _15(4)>
*coord_21(D) = _6;
The store for s_19(D)->p is not done but I think there might be already another
bug about that.
