Proof step 3 from proof inv-remap (previous step)

# wbuf.content = EB_PAGE_SIZE, # lpt = # avol, buffered(m) ≠ bleb, m < # avol, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_remap#(m, bleb, adr, m0, plog, lpt, ns; avol; err)⟫ ((bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ ebm-vol-inv(avol) ∧ # lpt = # avol)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
# lpt = # avol, # buf = EB_PAGE_SIZE, wbuf = mkwbuf(buf, m1, m2), m < # avol, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_remap#(m, bleb, adr, m0, plog, lpt, ns; avol; err)⟫ ((bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ ebm-vol-inv(avol) ∧ # lpt = # avol), buffered(m) = bleb

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, m0, m1]

Additional information

Used simplifier rules: ⊦ (buf = wbuf.content ∧ m = wbuf.offset) ∧ m0 = wbuf.nbytes ↔ wbuf = mkwbuf(buf, m, m0); (elim) Used terms: wbuf, buf, m0, m1
