Proof step 132 from proof compat-addobj (previous step)

st[r0 -- _type] = typeval(mkclasstype(class0)), compatobj(str, r0, st), is_predefined_class(class), newref(r, st), compatmode(str, st), compatstatic(str, st), r0 -- _type ∈ st, r0 ∈ st, class+∃(str, class0) ⊦ r = jvmref, r0 = jvmref, compatfields(str, r0, instfields(class0), addobj(r, class, [], st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 115:
⊦ compatobj(str, r, st) ↔ is_classtype(st[r -- _type] .type) ∧ class+∃(str, st[r -- _type] .type .class) ∧ compatfields(str, r, instfields(st[r -- _type] .type .class), st)
Proof step 131:
st[r0 -- _type] = typeval(mkclasstype(class0)), is_classtype(st[r0 -- _type] .type) ∧ class+∃(str, st[r0 -- _type] .type .class) ∧ compatfields(str, r0, instfields(st[r0 -- _type] .type .class), st), is_predefined_class(class), newref(r, st), compatmode(str, st), compatstatic(str, st), r0 -- _type ∈ st, r0 ∈ st, class+∃(str, class0) ⊦ r = jvmref, r0 = jvmref, compatfields(str, r0, instfields(class0), addobj(r, class, [], st))
