Proof step 27 from proof junkref-put-refval-01 (previous step)

is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, validref(str, r1, ty, st), junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), r1 = jvmref → is_reftype(ty) ⊦ r0 = jvmref, junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ¬ junkrefs(str, refs, ty, st) ∧ ¬ junkref(str, r0, st) ∧ mkarraytype(st[r0 -- _type] .type) ≤ st[r -- _type] .type ∧ r ≠ jvmref ∧ r0 ≠ jvmref → ¬ junkrefs(str, refs, ty, st[r -- i ', refval(r0)])
Proof step 26:
¬ ( ¬ junkrefs(str, r ' + refs0, st[r -- _type] .type, st) ∧ ¬ junkref(str, r1, st) ∧ mkarraytype(st[r1 -- _type] .type) ≤ st[r0 -- _type] .type ∧ r0 ≠ jvmref ∧ r1 ≠ jvmref), is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, validref(str, r1, ty, st), junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), r1 = jvmref → is_reftype(ty) ⊦ r0 = jvmref, junkref(str, r, st)
