Proof step 60 from proof hasSharing-put-index-refval (previous step)

(st[st[r2 -- sks1] .refval -- i ', refval(r2)][r2 -- (sks0 + i ' ' + sks)]) = refval(r2), st[st[r2 -- sks1] .refval -- _type] .type = mkarraytype(ty), st[r2 -- sks0] = refval(st[r2 -- sks1] .refval), sks1 + i ' ' ⊑ sks0, fits(r2, sks0 + i ' ' + sks, st), validref(str, r2, ty, st), disjoint(str, st[r2 -- sks1] .refval ' + r2 ', st), 0 ≤ i, i < st[st[r2 -- sks1] .refval -- _length] .intval, 0 < st[st[r2 -- sks1] .refval -- _length] .intval, ∀ sks. sks + i ' ' ⊑ sks0 → st[r2 -- sks] .refval ≠ st[r2 -- sks1] .refval ⊦ r2 = jvmref, st[r2 -- sks1] .refval = r2, st[r2 -- sks1] .refval = jvmref, hasSharing(st[r2 -- sks1] .refval, st), hasSharing(r2, st), junkref(str, st[r2 -- sks1] .refval, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 59:
st[r2 -- sks1] = refval(r) ∧ is_referencevalue(st[r2 -- sks1]), (st[r -- i ', refval(r2)][r2 -- (sks0 + i ' ' + sks)]) = refval(r2), st[r -- _type] .type = mkarraytype(ty), st[r2 -- sks0] = refval(r), sks1 + i ' ' ⊑ sks0, fits(r2, sks0 + i ' ' + sks, st), validref(str, r2, ty, st), disjoint(str, r ' + r2 ', st), 0 ≤ i, i < st[r -- _length] .intval, 0 < st[r -- _length] .intval, ∀ sks. sks + i ' ' ⊑ sks0 → st[r2 -- sks] .refval ≠ r ⊦ r2 = jvmref, r = r2, r = jvmref, hasSharing(r, st), hasSharing(r2, st), junkref(str, r, st)
