Proof step 3 from proof at-other-13 (conclusion)

⊦ (st[r0 -- mkfs(class, boolean_type, fieldvar) ', val][_mode]) = st[_mode]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ (st[rk0, val][rk]) = ((rk = rk0 ⊃ val; st[rk]))
Proof step 2:
⊦ ((_mode = r0 -- mkfs(class, boolean_type, fieldvar) ' ⊃ val; st[_mode])) = st[_mode]

Rule argument
