So the proposed patch (for all branches) is:
Index: tree.c
===================================================================
*** tree.c (revision 120477)
--- tree.c (working copy)
*************** get_narrower (tree op, int *unsignedp_pt
*** 5485,5494 ****
{
if (first)
uns = DECL_UNSIGNED (TREE_OPERAND (op, 1));
! win = build3 (COMPONENT_REF, type, TREE_OPERAND (op, 0),
! TREE_OPERAND (op, 1), NULL_TREE);
! TREE_SIDE_EFFECTS (win) = TREE_SIDE_EFFECTS (op);
! TREE_THIS_VOLATILE (win) = TREE_THIS_VOLATILE (op);
}
}
*unsignedp_ptr = uns;
--- 5485,5491 ----
{
if (first)
uns = DECL_UNSIGNED (TREE_OPERAND (op, 1));
! win = fold_convert (type, op);
}
}
*unsignedp_ptr = uns;
