Proof step 9 from proof crash-gstore-inv (previous step)

dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), n ∈ gstore, n ∈ gstore \ ginval → inv((gstore \ ginval)[n]) ⊦ inv(crash(gstore, gstore0, ginval, nx)[n]), n ∈ ginval

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), inv(gstore[n]), n ∈ gstore ⊦ inv(crash(gstore, gstore0, ginval, nx)[n]), n ∈ ginval

Rule argument

Additional information

Used simplifier rules: ⊦ ¬ n ∈ ns → (gstore \ ns)[n] = gstore[n]; (s)% ⊦ n ∈ gstore \ ns ↔ n ∈ gstore ∧ ¬ n ∈ ns; (ws)
