Proof step 4 from proof bytevalues-eq (previous step)

val ∈ getarray(r, i, j, st), 0 ≤ i0, r0 ∈ st, 0 ≤ i, r ∈ st, i0 + j0 ≤ st[r0 -- _length] .intval, okarray(r0, byte_type, st), i + j ≤ st[r -- _length] .intval, okarray(r, byte_type, st) ⊦ r0 = jvmref, r = jvmref, bytevalues(getarray(r, i, j, st)) = bytevalues(getarray(r0, i0, j0, st)) ↔ getarray(r, i, j, st) = getarray(r0, i0, j0, st), is_bytevalue(val)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ okarray(r, byte_type, st) ∧ i + j ≤ st[r -- _length] .intval ∧ 0 ≤ i ∧ ¬ is_bytevalue(val) → ¬ val ∈ getarray(r, i, j, st)

Rule argument

[crewrite-arg: okbytearray , F , [st, j, i, r, val] → [st, j, i, r, val] ]
