Proof step 5 from proof init-put-field-01 (previous step)

¬ sks ≠ [] ⊦ ty = void_type, init(st[r -- (sks + mkfs(class, ty, fieldvar) ' '), val]) ↔ init(st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ st[r -- sk ', val] = st[r -- sk, val]
Proof step 4:
⊦ ty = void_type, init(st[r -- mkfs(class, ty, fieldvar) ', val]) ↔ init(st)

Rule argument
