Proof step 6 from proof exactarray-intval-01 (previous step)

exactarray(r, ty, st), r ∈ st ⊦ intval(st[r -- _length] .intval) = st[r -- _length], r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
is_integervalue(val) ⊦ intval(val .intval) = val
Proof step 5:
¬ is_integervalue(st[r -- _length]), exactarray(r, ty, st), r ∈ st ⊦ intval(st[r -- _length] .intval) = st[r -- _length], r = jvmref

Rule argument

[speclemmaarg: is_integervalue(val) ,intval(val .intval) = val ,[val] → [st[r -- _length]] ,F ,javavalue , ,intval ]
