Proof step 11 from proof referenced-adrs-split (previous step)

adr ' + referenced-adrs(ax2, ri) = ax0 + ax1, ax0 = adr0 + ax5, adr ∈ ri, ∀ ri, ax0, ax1. referenced-adrs(ax2, ri) = ax0 + ax1 → (∃ ax4, ax3. ax2 = ax4 + ax3 ∧ referenced-adrs(ax4, ri) = ax0 ∧ referenced-adrs(ax3, ri) = ax1), adr ∈ ax0 ∨ adr ∈ ax1 ⊦ ∃ ax, ax3. adr ' + ax2 = ax + ax3 ∧ referenced-adrs(ax, ri) = ax0 ∧ referenced-adrs(ax3, ri) = ax1

And obtained the following new goals

Proof step 12:
referenced-adrs(ax2, ri) = ax5 + ax1, adr0 ∈ ri, ∀ ri, ax0, ax1. referenced-adrs(ax2, ri) = ax0 + ax1 → (∃ ax4, ax3. ax2 = ax4 + ax3 ∧ referenced-adrs(ax4, ri) = ax0 ∧ referenced-adrs(ax3, ri) = ax1) ⊦ ∃ ax, ax0. adr0 ' + ax2 = ax + ax0 ∧ referenced-adrs(ax, ri) = adr0 ' + ax5 ∧ referenced-adrs(ax0, ri) = ax1

Additional information

Used simplifier rules: ⊦ adr ∈ adr0 ' + ax ↔ adr = adr0 ∨ adr ∈ ax; (s)% ⊦ adr ' + ax = adr0 ' + ax0 ↔ adr = adr0 ∧ ax = ax0; (ws)%a: ⊦ (ax + ax0) + ax1 = ax + ax0 + ax1; from specification list[address-list-set]% ⊦ adr + ax = adr ' + ax; (s)
