How do you plan to solve it?

module univ_barrel8(x,sh,mode,y);
input [7:0] x;
input [2:0] sh,mode;
output reg [7:0] y;
always @(*)begin
    y=8'b0;
    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);
    3'b101: y=(x>>sh)|(x<<8-sh);
    default : y=x;
    endcase
end
