Proof step 30 from proof nodes-remove-refsize0 (previous step)

remove-refsize0(gstore)[@(m, m0, m1)] = mkgnode(nd, m3, boolvar, boolvar0), gstore[m] = groupblock(gndx, lax, m2), dom remove-refsize0(gstore) ∩ ginval = ∅, m ∈ gstore, @(m0, m1) ∈ lax, @(m, m0, m1) ∈ remove-refsize0(gstore) ⊦ m2 = 0, nd = nodes(gstore, ginval)[@(m, m0, m1)], @(m, m0, m1) ∈ refsize0-addresses(gstore \ ginval)

And obtained the following new goals

Proof step 31:
gstore[m] = groupblock(gndx, lax, m2), remove-refsize0(gstore)[@(m, m0, m1)] = mkgnode(nd, m3, boolvar, boolvar0), dom remove-refsize0(gstore) ∩ ginval = ∅, @(m, m0, m1) ∈ remove-refsize0(gstore), @(m0, m1) ∈ lax, m ∈ gstore ⊦ m2 = 0, nd = nodes(gstore, ginval)[@(m, m0, m1)], @(m, m0, m1) ∈ gstore \ ginval ∧ (gstore \ ginval)[m].ref-size = 0

Additional information

Used simplifier rules: refsize0-addresses: ⊦ adr ∈ refsize0-addresses(gstore) ↔ ¬ ¬(adr ∈ gstore ∧ gstore[adr.lnum].ref-size = 0);% ⊦ @(m, m0, m1).lnum = m; (s)
