Proof step 7 from proof hasSharing-put-byteval (previous step)

st[r -- sks] = refval(r0), st[r -- sks0] = refval(r0), fits(r, sks0, st), fits(r, sks, st), i < st[r1 -- _length] .intval, okarray(r1, byte_type, st), 0 ≤ i, 0 < st[r1 -- _length] .intval, r1 ∈ st ⊦ sks0 = sks, sks0 = [], sks = [], r0 = jvmref, r1 = jvmref, fits(r, sks0, st[r1 -- i ', byteval(by)]), junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ ¬ junkref(str, r, st) ∧ is_referencevalue(st[r -- sks]) ∧ okarray(r1, byte_type, st) ∧ fits(r, sks, st) → fits(r, sks, st[r1 -- i ', byteval(by)])

Rule argument

[crewrite-arg: fits-put-01 , F , [str, r, st, sks, r1, i, by] → [str, r, st, sks0, r1, i, by] ]
