> OFFSET + &OBJ.
Well pointer plus was merged so it is always &OBJ + OFFSET :).

Indeed with -fno-tree-ccp the testcase is optimized by forwprop1 to
:
D.2000_3 = i_2(D) * 4;
D.2001_4 = (int *) D.2000_3;
D.2002_5 = &b.t[i_2(D)];
*D.2002_5 = 1;
return;
and then by forwprop2 to
:
D.20

Actually this is just a tree-combining issue. CCP already transforms this to
c_1 = &b.t[0];
D.2000_3 = i_2(D) * 4;
D.2001_4 = (int *) D.2000_3;
D.2002_5 = D.2001_4 + &b.t[0];
*D.2002_5 = 1;
not combining

is this fixed on pointer_plus branch? Confirmed on the mainline.
