Proof step 17 from proof referenced-adrs-split (previous step)

referenced-adrs(ax2, 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 ∈ ri, ∃ ax, ax3. adr ' + ax2 = ax + ax3 ∧ referenced-adrs(ax, ri) = ax0 ∧ referenced-adrs(ax3, ri) = ax1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 18:
⊦ adr ∈ ri, ∃ ax1, ax4. adr ' + ax + ax3 = ax1 + ax4 ∧ referenced-adrs(ax1, ri) = referenced-adrs(ax, ri) ∧ referenced-adrs(ax4, ri) = referenced-adrs(ax3, ri)

Rule argument

Additional information

Used simplifier rules: referenced-adrs-app: ⊦ referenced-adrs(ax0 + ax1, ri) = referenced-adrs(ax0, ri) + referenced-adrs(ax1, ri);% ⊦ ax + ax0 = ax + ax1 ↔ ax0 = ax1; (s)%a: ⊦ (ax + ax0) + ax1 = ax + ax0 + ax1; from specification list[address-list-set]
