Proof step 348 from proof refine-read-buf (previous step)

# buf2 = EB_PAGE_SIZE, # lpt0 = # avol1, # avol0 = # avol1, avol0[bleb.leb] = mapped(buf), avol1[m2] = mapped(buf1), bleb.leb < # avol1, m2 < # avol1, LEB_SIZE < # avol0[m2].data, m0 + n < # avol0[m2].data, m4 < EB_PAGE_SIZE, abs(avol1, bleb, mkwbuf(buf2, m6, m4), avol0, rofs), awbuf-inv(avol1, bleb), ebm-vol-inv(avol0), is-aligned(m6, EB_PAGE_SIZE), m0 + n ≤ LEB_SIZE, n ≤ # buf3, m0 + n ≤ # avol0[m2].data + (LEB_SIZE - # avol0[m2].data), rofs → m6 ≤ # buf, ¬ rofs → # buf = m6 ⊦ bleb = nobuffer

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 349:
# avol0 = # avol1, # lpt0 = # avol1, # buf2 = EB_PAGE_SIZE, avol1[m2] = mapped(buf1), avol0[m] = mapped(buf), bleb = buffered(m), m4 < EB_PAGE_SIZE, m0 + n < # avol0[m2].data, LEB_SIZE < # avol0[m2].data, m2 < # avol1, m < # avol1, abs(avol1, bleb, mkwbuf(buf2, m6, m4), avol0, rofs), awbuf-inv(avol1, bleb), ebm-vol-inv(avol0), is-aligned(m6, EB_PAGE_SIZE), m0 + n ≤ # avol0[m2].data + (LEB_SIZE - # avol0[m2].data), n ≤ # buf3, m0 + n ≤ LEB_SIZE, ¬ rofs → # buf = m6, rofs → m6 ≤ # buf ⊦ bleb = nobuffer

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
