Proof step 26 from proof nodes-remove-refsize0 (previous step)

gstore[m] = groupblock(gndx, lax, m2), dom remove-refsize0(gstore) ∩ ginval = ∅, @(m0, m1) ∈ lax, m ∈ gstore, @(m, m0, m1) ∈ nodes(remove-refsize0(gstore), ∅) ⊦ remove-refsize0(gstore)[@(m, m0, m1)].nd = (nodes(gstore, ginval) \ refsize0-addresses(gstore \ ginval))[@(m, m0, m1)], m2 = 0

Proof step 27:
gstore[m] = groupblock(gndx, lax, m2), dom remove-refsize0(gstore) ∩ ginval = ∅, m ∈ gstore, @(m0, m1) ∈ lax, @(m, m0, m1) ∈ remove-refsize0(gstore) ⊦ remove-refsize0(gstore)[@(m, m0, m1)].nd = (nodes(gstore, ginval) \ refsize0-addresses(gstore \ ginval))[@(m, m0, m1)], m2 = 0

Additional information

Used simplifier rules: nodes-gstore-in: ⊦ adr ∈ nodes(gstore, ginval) ↔ ¬ ¬(adr ∈ gstore ∧ ¬ adr.lnum ∈ ginval);% ⊦ ¬ n ∈ ∅; (s)% ⊦ @(m, m0, m1).lnum = m; (s)
