Question

Consider the following ARM assembly code:
functioni: push (14-110, fp)
add fp. p.
add
// allocate decal variable space
add 14.0,r1 // 14=r0+r1
add r5,12,13 // IS=r2+r3
add 16.14.15
1/ réər 4+
str re.Ifp.-
r0, Ifp*-// ri-A
pop
(14-710, fp
For the given ARM code, why register rll is not pushed in the routine function ( in the first
statement)?
a) rll is not used as the local variable
b) rll is not exist in ARM assembly register set
c) rll is pushed
d) pushing 14-r10 is enough

Answer 1

Answer:

ratio 2/9=2:9=0.22

ratio 18/81=18:81=0.22

so , yes they are in proportion.

2/9:18/81 - proper form
