Proof step 7 from proof inv-enter-readonly (previous step)

# buf = EB_PAGE_SIZE, avol[bleb.leb] = mapped(buf0), bleb.leb < # avol, wbuf-cons(mkwbuf(buf, m, m0), mapped(buf0), rofs) ⊦ bleb = nobuffer, wbuf-cons(mkwbuf(buf, m, m0), mapped(buf0), true)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 8:
# buf = EB_PAGE_SIZE, avol[m1] = mapped(buf0), bleb = buffered(m1), m1 < # avol, wbuf-cons(mkwbuf(buf, m, m0), mapped(buf0), rofs) ⊦ bleb = nobuffer, wbuf-cons(mkwbuf(buf, m, m0), mapped(buf0), true)

Rule argument

spec: bufleb name: elim seq: ⊦ bleb ≠ nobuffer → (m = bleb.leb ↔ bleb = buffered(m)) subst: [bleb, m] → [bleb, m1]

Additional information

Used simplifier rules: ⊦ bleb ≠ nobuffer → (m = bleb.leb ↔ bleb = buffered(m)); (elim) Used terms: bleb, m1
