Proof step 14 from proof sharing-pathex-field-self (previous step)

st[r0 -- fs '] = refval(r0), is_classtype(st[r0 -- _type] .type), fs ' ∈ instfields(st[r0 -- _type] .type .class), is_valid_ref(`docs2store', r0, st) ⊦ r0 = jvmref, hasSharing(r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ hasSharing(r, st) ↔ (∃ sks1, sks2. fits(r, sks1, st) ∧ fits(r, sks2, st) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ st[r -- sks1] .refval ≠ jvmref ∧ st[r -- sks1] = st[r -- sks2])
Proof step 13:
st[r0 -- fs '] = refval(r0), is_classtype(st[r0 -- _type] .type), fs ' ∈ instfields(st[r0 -- _type] .type .class), is_valid_ref(`docs2store', r0, st) ⊦ r0 = jvmref, ∃ sks1, sks2. fits(r0, sks1, st) ∧ fits(r0, sks2, st) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ st[r0 -- sks1] .refval ≠ jvmref ∧ st[r0 -- sks1] = st[r0 -- sks2]

Rule argument

[crewrite-arg: hasSharing-def, F, [st, r] → [st, r0]]
