Proof step 34 from proof refine-remap (previous step)

avol = abs(avols0[default-volid]), err = ESUCCESS, m < # avols0[default-volid], ebm-cons(avols0), ebm-vol-inv(abs(avols0[default-volid])), default-volid ∈ avols0 ⊦ ⟨avol[m] := mapped(mkbuf(0))⟩ (avol = abs(avols0[default-volid][m, mapped(emptyleb, 0)]) ∧ ESUCCESS = err)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 35:
avol = abs(avols0[default-volid]), err = ESUCCESS, m < # avol, m < # avols0[default-volid], ebm-cons(avols0), ebm-vol-inv(abs(avols0[default-volid])), default-volid ∈ avols0 ⊦ avol[m, mapped(mkbuf(0))] = abs(avols0[default-volid][m, mapped(emptyleb, 0)]) ∧ ESUCCESS = err

Additional information

Used simplifier rules: ⊦ # abs(evol) = # evol; (s)% ⊦ m < n ↔ ¬ n ≤ m; (ss)% ⊦ m < n → (n ≤ m ↔ false); (s)
