Proof step 6 from proof refine-get-volume-size (previous step)

v = default-volid, ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ ⟪n := # avols[v]⟫ ⟨ebm_avol_get_volume_size#(abs(avols[default-volid]); ; n0)⟩ (n = n0)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 7:
v = default-volid, ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), v ∈ avols, default-volid ∈ avols ⊦ ⟨ebm_avol_get_volume_size#(abs(avols[default-volid]); ; n0)⟩ (# avols[v] = n0)

Rule argument

Additional information

Used simplifier rules: ⊦ ¬ v ∈ avols → avols[v] = (∅)[v]; (s)
