Proof step 1 from proof inv-format (conclusion)

m = # lpt, m0 = LEB_SIZE ⊦ ⟪wbuf_format#(m, m0, lpt, adr, m1; wbuf, m2, adr0, m3, plog, avol, lpt0, ns, bleb, rofs; err)⟫ (err = ESUCCESS → wbuf-cons(bleb, wbuf, avol, rofs) ∧ m2 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol) ∧ # lpt0 = # avol)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ ⟪wbuf_format#(# lpt, LEB_SIZE, lpt, adr, m1; wbuf, m2, adr0, m3, plog, avol, lpt0, ns, bleb, rofs; err)⟫ ( err = ESUCCESS → # wbuf.content = EB_PAGE_SIZE ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ m2 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol) ∧ # lpt0 = # avol)

Rule argument

Additional information

Used simplifier rules: ⊦ wbuf-cons(bleb, wbuf, avol, rofs) ↔ # wbuf.content = EB_PAGE_SIZE ∧ ( bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)); (s)
