Proof step 34 from proof hasSharing-put-shortval (previous step)

is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']) ⊦ ¬ hasSharing(r0, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ↔ ¬ hasSharing(r0, st), r = jvmref, junkref(str, r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 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 33:
is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']) ⊦ ¬ (∃ sks1, sks2. fits(r0, sks1, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ∧ fits(r0, sks2, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks1]) .refval ≠ jvmref ∧ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks1]) = (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks2])) ↔ ¬ hasSharing(r0, st), r = jvmref, junkref(str, r0, st)
