Proof step 7 from proof bytevalues-eq (previous step)

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), val ∈ getarray(r, i, j, st) ∨ val ∈ getarray(r0, i0, j0, 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)

And obtained the following new goals

Proof step 4:
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)
Proof step 6:
val ∈ getarray(r0, i0, j0, 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)
