Proof step 4 from proof crash-neutral-add-log-leb (previous step)

# lpt = # avol, avol[m3] = mapped(buf), adr = adr0, m = m2, m0 = # avol[m3].data, m1 = m3, ns = ns0, nx = nx0, nx1 = nx0, avol[m3].mapped?, m3 < # avol, awbuf-inv(avol, bleb), synced(avol), synced(avol0), avol0 ↓ avol ⊦ ⟨if m1 < # avol ∧ avol[m1].mapped? ∧ m0 = # avol[m1].data ∧ synced(avol) then {fail_or_success#(; ; err); if err = ESUCCESS then nx := nx + m1, bleb := buffered(m1)} else abort⟩ (nx1 = nx)

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 5:
# lpt = # avol, avol[m3] = mapped(buf), adr = adr0, m = m2, m0 = # avol[m3].data, m1 = m3, ns = ns0, nx = nx0, nx1 = nx0, avol[m3].mapped?, m3 < # avol, awbuf-inv(avol, bleb), synced(avol0), synced(avol), avol0 ↓ avol ⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then nx := nx + m1, bleb := buffered(m1)⟩ (nx1 = nx)

Rule argument

pos: right 1
