A processor uses register renaming to reduce the number of apparent conflicts between instructions. Rewrite the LEGV8 code below to reflect how it would look after renaming. (15 pts) ADDI XO, XZR #0 ADDI X1, XZR, #8 ADD X0, X0, X1 ADDI X1, X1, #1 ADD X0, X0, X1 ADDI X1, X1, #1 ADD X0, X0, X1 ADDI X1, X1, #1 ADD X0, X0, X1 Explain why a processor should use registers renaming technique, with an example where register renaming helps processor performance (WAR or WAW dependency).
