Proof step 5 from proof validref-addobj-this (previous step)

fis .keys = instfields(class), class ≤ class0, newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), tdname+∃(str, class0), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, validref(str, r, mkclasstype(class0), addobj(r, class, fis, st)), is_abstract(class)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validref(str, r, ty, st) ↔ r = jvmref ∨ st[r -- _type] .type ≤ ty ∧ ¬ junkref(str, r, st)
Proof step 4:
fis .keys = instfields(class), class ≤ class0, newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), tdname+∃(str, class0), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, r = jvmref ∨ (addobj(r, class, fis, st)[r -- _type]) .type ≤ mkclasstype(class0) ∧ ¬ junkref(str, r, addobj(r, class, fis, st)), is_abstract(class)

Rule argument

[crewrite-arg: validref-def , F , [st, ty, r, str] → [addobj(r, class, fis, st), mkclasstype(class0), r, str] ]
