Proof step 21 from proof junkrefs-put-ba (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 20:
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)
