    always @(x or sh or mode)
        case (mode)
            3'b000: y = x;
            3'b001: y = x << sh;
            3'b010: y = x >> sh;
            3'b011: y = $signed(x) >>> sh;
            3'b100: y = ((x << sh) | (x >> (8 - sh))) & 8'hFF;
            3'b101: y = ((x >> sh) | (x << (8 - sh))) & 8'hFF;
            default: y = x;
