Proof step 12:
st[r0 -- sks0] = st[r0 -- sks], fits(r0, sks0, st), fits(r0, sks, st), is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), ∀ sks, sks0. ¬ 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]) ⊦ sks0 = sks, sks0 = [], sks = [], st[r0 -- sks] .refval = jvmref, r = jvmref, junkref(str, r0, st)
