Proof step 4 from proof refine-sync-device (previous step)

ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ ⟪ebm_sync_device#(avols; ; err)⟫ ⟨ebm_avol_sync_device#(abs(avols[default-volid]); ; err0)⟩ (err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 5:
ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ ⟪fail_or_success#(; ; err)⟫ ⟨ebm_avol_sync_device#(abs(avols[default-volid]); ; err0)⟩ (err = err0)

Rule argument

pos: right 1

Additional information

Used simplifier rules: ebm_sync_device#(AVOLS; ; ERR){fail_or_success#(; ; ERR)};
