PR target/9348 * expr.c (expand_expr_real) <MULT_EXPR>: When performing widening multiplies with a multiplication of the wrong signedness, its the signedness of the multiplication that we've performed that needs to be passed to expand_mult_highpart_adjust. Avoid emitting a nop-move if expand_mult_highpart_adjust places the result in target. * gcc.c-torture/execute/multdi-1.c: New test case. From-SVN: r77192
