Proof step 9 from proof icrash-inv (previous step)

crash(istore, istore0)[n] = indexblock(indx, lax, m), inv(istore), n ∈ istore0, n ∈ istore, n ∈ crash(istore, istore0), istore0 ⊑ istore ⊦ crash(istore, istore0)[n].ref-size = 0, m = 0, inv(crash(istore, istore0)[n])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
crash(istore, istore0)[n] = indexblock(indx, lax, m), inv(istore), n ∈ istore0, n ∈ istore, istore0 ⊑ istore ⊦ m = 0, inv(indexblock(indx, lax, m))

Rule argument

Additional information

Used simplifier rules: crash-index-in: ⊦ n ∈ crash(istore, istore0) ↔ n ∈ istore0;% ⊦ indexblock(indx, lax, m).ref-size = m; (s)
