Proof step 16 from proof crash-gstore-inv (previous step)

(n ∈ nx ∨ ¬ n ∈ ginval ⊃ groupblock(gstore[n].gndlist, gstore[n].ladrlist, (n ∈ gstore0 ⊃ gstore0[n].ref-size;0));gstore0[n]) = groupblock(gndx, lax, m), dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), inv(gstore[n]), n ∈ gstore, n ∈ crash(gstore, gstore0, ginval, nx) ⊦ n ∈ ginval, inv-flashsize(gndx, lax) ∧ ¬ dups(lax)

And obtained the following new goals

Proof step 17:
dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), inv(gstore[n]), n ∈ gstore ⊦ n ∈ ginval, inv-flashsize(gstore[n].gndlist, gstore[n].ladrlist) ∧ ¬ dups(gstore[n].ladrlist)

Rule argument

Additional information

Used simplifier rules: crash-group-in: ⊦ n ∈ crash(gstore, gstore0, ginval, nx) ↔ n ∈ gstore ∨ n ∈ ginval;%⊦ groupblock(gndx, lax, m) = groupblock(gndx0, lax0, m0) ↔ gndx = gndx0 ∧ lax = lax0 ∧ m = m0; (ws)
