Proof step 63 from proof junkrefs-put-refval-02 (previous step)

mkarraytype(st[r0 -- _type] .type) ≤ st[r -- _type] .type, junkrefs(str, refs, ty, st[r -- i ', refval(r0)]) ⊦ r = jvmref, r0 = jvmref, junkrefs(str, refs, ty, st), junkref(str, r0, st)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ ¬ junkrefs(str, [], ty, st)
Proof step 62:
∀ st, r0, r, str, ty, i. mkarraytype(st[r0 -- _type] .type) ≤ st[r -- _type] .type ∧ junkrefs(str, acc, ty, st[r -- i ', refval(r0)]) → r = jvmref ∨ r0 = jvmref ∨ junkrefs(str, acc, ty, st) ∨ junkref(str, r0, st), mkarraytype(st[r0 -- _type] .type) ≤ st[r -- _type] .type, junkrefs(str, r1 + acc, ty, st[r -- i ', refval(r0)]) ⊦ r = jvmref, r0 = jvmref, junkrefs(str, r1 + acc, ty, st), junkref(str, r0, st)
