Proof step 51 from proof hasSharing-put-index-refval (previous step)

st[r2 -- sks] = refval(r), (st[r -- i ', refval(r2)][r2 -- (sks + i ' ' + sks0)]) = refval(r2), st[r -- _type] .type = mkarraytype(ty), fits((st[r -- i ', refval(r2)][r2 -- sks]) .refval, i ' ' + sks0, st[r -- i ', refval(r2)]), fits(r2, sks, st[r -- i ', refval(r2)]), validref(str, r2, ty, st), disjoint(str, r ' + r2 ', st), 0 ≤ i, i < st[r -- _length] .intval, 0 < st[r -- _length] .intval ⊦ r2 = jvmref, r = r2, r = jvmref, hasSharing(r, st), hasSharing(r2, st), junkref(str, r, st), ∃ sks2. ¬ (sks2 + i ' ' ⊑ sks → st[r2 -- sks2] .refval ≠ r)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 29:
⊦ fits(jvmref, sks, st) ↔ sks = []
Proof step 50:
(st[r -- i ', refval(r2)][r2 -- sks]) = refval(r0) ∧ is_referencevalue(st[r -- i ', refval(r2)][r2 -- sks]), st[r2 -- sks] = refval(r), (st[r -- i ', refval(r2)][r2 -- (sks + i ' ' + sks0)]) = refval(r2), st[r -- _type] .type = mkarraytype(ty), fits(r0, i ' ' + sks0, st[r -- i ', refval(r2)]), fits(r2, sks, st[r -- i ', refval(r2)]), validref(str, r2, ty, st), disjoint(str, r ' + r2 ', st), 0 ≤ i, i < st[r -- _length] .intval, 0 < st[r -- _length] .intval ⊦ r2 = jvmref, r = r2, r = jvmref, hasSharing(r, st), hasSharing(r2, st), junkref(str, r, st), ∃ sks2. ¬ (sks2 + i ' ' ⊑ sks → st[r2 -- sks2] .refval ≠ r)
