Proof step 6 from proof icrash-inv (previous step)

inv(istore), n ∈ istore0, n ∈ istore, istore0 ⊑ istore ⊦ crash(istore, istore0)[n].ref-size = 0, inv(remove-refsize0(crash(istore, istore0))[n])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
crash(istore, istore0)[n] = indexblock(indx, lax, m), inv(istore), n ∈ istore, n ∈ istore0, istore0 ⊑ istore ⊦ m = 0, inv(remove-refsize0(crash(istore, istore0))[n])

Rule argument

spec: ablock, inst: index-store name: elim seq: ⊦ (indx = iblock.indlist ∧ lax = iblock.ladrlist) ∧ m = iblock.ref-size ↔ iblock = indexblock(indx, lax, m) subst: [iblock, indx, lax, m] → [crash(istore, istore0)[n], indx, lax, m]

Additional information

Used simplifier rules: ⊦ (indx = iblock.indlist ∧ lax = iblock.ladrlist) ∧ m = iblock.ref-size ↔ iblock = indexblock(indx, lax, m); (elim) Used terms: crash(istore, istore0)[n], indx, lax, m
