Vectorizing Compiler (30 marks) Consider this familiar loop: loop: l.d f4,0(r1) l1 l.d f6,0(r2) l2 mul.d f4,f4,f0 m1 mul.d f6,f6,f2 m2 add.d f4,f4,f6 a1 s.d f4,0(r1) s1 daddui r1,r1,#-8 sub1 daddui r2,r2,#-8 sub2 bnez r1,loop br Rewrite the code using vector instructions. Draw the flow-dependence graph of vector instructions. Using vector chaining, make a rough estimate of the running time of the program, using the data in question 1.
