Proof step 20 from proof junkrefs-put-ba (previous step)

st[r0 -- _type] = typeval(mkarraytype(byte_type)), fs .type = mkarraytype(byte_type), is_array(r0, st), junkrefs(str, refs, ty, st[r1 -- fs ', refval(r0)]) ⊦ junkrefs(str, refs, ty, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 19:
fs = mkfs(class, ty0, fieldvar), st[r0 -- _type] = typeval(mkarraytype(byte_type)), ty0 = mkarraytype(byte_type), is_array(r0, st), junkrefs(str, refs, ty, st[r1 -- fs ', refval(r0)]) ⊦ junkrefs(str, refs, ty, st)

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty0, fieldvar] ,T ,fieldspec , ,elim ]
