Given code for a loop:

Each iteration of the loop potentially collides with the previous iteration of the loop

because it is so small.Use register renaming to avoid these collisions. Assume your

processor has a pool of temporary registers $($called T$0$ through T$63).$ This rename

hardware is indexed by the src $($source$)$ register designation and the value in the

table is the $T$ register of the last destination that targeted that register. For the

previously given code, every time you see a destination register, substitute the next

available $T$ register beginning with $T9.$ Then update all the src registers

accordingly, so that true data dependencies are maintained. The first two lines are

given:

Loop: $fldT9,0(Rx)$

$I0$: fmul.$dT10,f0,T9$
