@@ -4195,7 +4184,8 @@ gimplify_modify_expr (tree *expr_p, gimp
side as statements and throw away the assignment. Do this after
gimplify_modify_expr_rhs so we handle TARGET_EXPRs of addressable
types properly. */
- if (zero_sized_type (TREE_TYPE (*from_p)) && !want_value)
+ if (int_expr_size (*from_p) == 0
+ && !want_value)
{
gimplify_stmt (from_p, pre_p);
gimplify_stmt (to_p, pre_p);
