Proof step 66 from proof pathex-put-cyclic (previous step)

is_classtype(st[r -- _type] .type), st[r0 -- _type] .type ≤ ty, mkfs(class, ty, fieldvar) ' ∈ instfields(st[r -- _type] .type .class), path∃(str, r0, r, st) ⊦ r = jvmref, r0 = jvmref, cyclic(str, r, st[r -- mkfs(class, ty, fieldvar) ', refval(r0)])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 65:
st[r -- _type] .type = mkclasstype(class0), is_classtype(st[r -- _type] .type), st[r0 -- _type] .type ≤ ty, mkfs(class, ty, fieldvar) ' ∈ instfields(class0), path∃(str, r0, r, st) ⊦ r = jvmref, r0 = jvmref, cyclic(str, r, st[r -- mkfs(class, ty, fieldvar) ', refval(r0)])

Rule argument

[speclemmaarg: ,is_classtype(ty) → (class = ty .class ↔ ty = mkclasstype(class)) ,[ty, class] → [st[r -- _type] .type, class0] ,T ,javatype , ,elim-02 ]
