Proof step 2 from proof add-field-same-01 (conclusion)

⊦ (addobj(r, class, (mkfs(class0, int_type, fieldvar0) ' × val) ' + fis, st)[r -- mkfs(class1, boolean_type, fieldvar1) ']) = (addobj(r, class, fis, st)[r -- mkfs(class1, boolean_type, fieldvar1) '])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ addobj(r, class1, (sk × val) ' + fis, st) = (addobj(r, class1, fis, st)[r -- sk, val])

Rule argument
