Proof step 27 from proof inv-commit (previous step)

# lpt = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, avol[bleb.leb] = mapped(buf0), bleb.leb < # avol, ebm-vol-inv(avol), wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), rofs), ⌊err0⌋ ⊦ bleb = nobuffer, wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), true)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 28:
# buf = EB_PAGE_SIZE, # lpt0 = # avol, # lpt = # avol, avol[m] = mapped(buf0), bleb = buffered(m), m < # avol, ebm-vol-inv(avol), wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), rofs), ⌊err0⌋ ⊦ bleb = nobuffer, wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), true)

Rule argument

spec: bufleb name: elim seq: ⊦ bleb ≠ nobuffer → (m = bleb.leb ↔ bleb = buffered(m)) subst: [bleb, m] → [bleb, m]

Additional information

Used simplifier rules: ⊦ bleb ≠ nobuffer → (m = bleb.leb ↔ bleb = buffered(m)); (elim) Used terms: bleb, m
