Proof step 44 from proof nodes-transaction (previous step)

# lax1 = # gndx1, # lax = # gndx, gstore[n] = groupblock(gndx, lax, m), gstore[@(n, m2, m3)] = mkgnode(nd, m4, boolvar, boolvar0), transaction(ndx, gndx1), n ∈ gstore, @(n, m2, m3) ∈ gstore ⊦ nd = nodes(gstore, ginval)[lax1.to-adr(n), ndx][@(n, m2, m3)], dups(lax1), dups(lax), dups(lax + lax1), @(m2, m3) ∈ lax1, n ∈ ginval

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 45:
⊦ # ax = # ndx ∧ ¬ adr ∈ ax → fs[ax, ndx][adr] = fs[adr]
Proof step 46:
# lax = # gndx, # lax1 = # gndx1, # lax1.to-adr(n) = # ndx, gstore[@(n, m2, m3)] = mkgnode(nd, m4, boolvar, boolvar0), gstore[n] = groupblock(gndx, lax, m), transaction(ndx, gndx1), @(n, m2, m3) ∈ gstore, n ∈ gstore ⊦ nd = nodes(gstore, ginval)[@(n, m2, m3)], dups(lax + lax1), dups(lax), dups(lax1), n ∈ ginval, @(m2, m3) ∈ lax1, @(n, m2, m3) ∈ lax1.to-adr(n)

Rule argument

spec: aubifs-base name: at-write-other seq: ⊦ # ax = # ndx ∧ ¬ adr ∈ ax → fs[ax, ndx][adr] = fs[adr] subst: [adr, ndx, ax, fs] → [@(n, m2, m3), ndx, lax1.to-adr(n), nodes(gstore, ginval)] flags: <all paths>

Additional information

Used simplifier rules: ⊦ # lax.to-adr(n) = # lax; (s)% ⊦ # gndx = n ∧ transaction(ndx, gndx) → (# ndx = n ↔ true); (ss)% ⊦ @(n0, n1, n2) ∈ lax.to-adr(n) ↔ n0 = n ∧ @(n1, n2) ∈ lax; (s) Used terms: @(n, m2, m3), ndx, lax1.to-adr(n), nodes(gstore, ginval)
