Proof step 6 from proof get-eqex-01 (previous step)

eqex(st, st0, r0) ⊦ getarray(r, st0) = getarray(r, st), r = r0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ eqex(st, st0, r) ↔ st -- r = st0 -- r
Proof step 5:
st -- r0 = st0 -- r0 ⊦ getarray(r, st0) = getarray(r, st), r = r0

Rule argument
