Proof step 3 from proof inv-get-volume-size (previous step)

# lpt = # avol, # wbuf.content = EB_PAGE_SIZE, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_get_volume_size#(adr, m, plog, avol, lpt, ns; ; n)⟫ true

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
# buf = EB_PAGE_SIZE, # lpt = # avol, wbuf = mkwbuf(buf, m0, m1), ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_get_volume_size#(adr, m, plog, avol, lpt, ns; ; n)⟫ true

Rule argument

spec: wbuf name: elim seq: ⊦ (buf = wbuf.content ∧ m = wbuf.offset) ∧ m0 = wbuf.nbytes ↔ wbuf = mkwbuf(buf, m, m0) subst: [wbuf, buf, m, m0] → [wbuf, buf, m, m0]

Additional information

Used simplifier rules: ⊦ (buf = wbuf.content ∧ m = wbuf.offset) ∧ m0 = wbuf.nbytes ↔ wbuf = mkwbuf(buf, m, m0); (elim) Used terms: wbuf, buf, m, m0
