three stages for a shifter (shifting by 0~7 bits)

Is there a way to implement a shifter (shifting by 0~7 bits) solely based on combinational logic? If it is a 3-stage shifter, the output of the previous shifter will be further shifted by all the shi...

A combinational shifter isn't but a multiplexer for each bit. Synthesis-wise, it's meaningless if you describe it as single- or multistage in your behavioral or structural code. The synthesis tool will chose an optimal implementation of the x8 multiplexers without your help.
