Proof step 5 from proof is_obj-refval (previous step)

mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ' ∈ instfields(st[r -- _type] .type .class) ⊦ is_obj(str, r, st) → refval(st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) '] .refval) = st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ']

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_referencevalue(val) → refval(val .refval) = val
Proof step 4:
¬ is_referencevalue(st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ']), mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ' ∈ instfields(st[r -- _type] .type .class) ⊦ is_obj(str, r, st) → refval(st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) '] .refval) = st[r -- mkfs(str2 .class, mkclasstype(str0 .class), str1 .field) ']
