Proof step 9 from proof hasSharing-put-shortval (previous step)

st[r0 -- sks0] = refval(r1), st[r0 -- sks] = refval(r1), is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), fits(r0, sks, st), fits(r0, sks0, st), ¬ fits(r0, sks, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ∨ ¬ fits(r0, sks0, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ∨ sks = sks0 ∨ sks = [] ∨ sks0 = [] ∨ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks]) .refval = jvmref ∨ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks]) ≠ (st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)][r0 -- sks0]) ⊦ r = jvmref, r1 = jvmref, sks = [], sks0 = [], sks0 = sks, junkref(str, r0, st)

And obtained the following new goals

Proof step 3:
⊦ ¬ junkref(str, r, st) ∧ fits(r, sks, st) ∧ is_shortvalue(st[r1 -- fs ']) → (st[r1 -- fs ', val][r -- sks]) = st[r -- sks]
Proof step 8:
st[r0 -- sks] = refval(r1), st[r0 -- sks0] = refval(r1), fits(r0, sks0, st), fits(r0, sks, st), is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), ¬ fits(r0, sks, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ∨ ¬ fits(r0, sks0, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ⊦ sks0 = sks, sks0 = [], sks = [], r1 = jvmref, r = jvmref, junkref(str, r0, st)
