Proof step 45 from proof refine-move-buf (previous step)

# avol0 = # avol1, # lpt0 = # avol1, # buf = EB_PAGE_SIZE, avol0[m5] = mapped(buf0), n < # avol1, m5 < # avol1, abs(avol1, bleb0, mkwbuf(buf, m4, m3), avol0, false), awbuf-inv(avol1, bleb0), ebm-vol-inv(avol0), bleb0 ≠ nobuffer → bleb0.leb < # avol1 ∧ wbuf-cons(mkwbuf(buf, m4, m3), avol0[bleb0.leb], false), bleb0 ≠ nobuffer → avol1[bleb0.leb].mapped? ∧ bleb0.leb < # avol1 ∧ bleb0.isbuf?, bleb0 = nobuffer ∨ is-aligned(# avol1[bleb0.leb].data, EB_PAGE_SIZE), bleb0 = nobuffer ∨ m3 = 0 ⊦ avol1[n] = avol0[n], bleb0 = buffered(m5), n = m5

And obtained the following new goals

Proof step 46:
# buf = EB_PAGE_SIZE, # lpt0 = # avol1, # avol0 = # avol1, avol0[m5] = mapped(buf0), m5 < # avol1, n < # avol1, abs(avol1, bleb0, mkwbuf(buf, m4, m3), avol0, false), awbuf-inv(avol1, bleb0), ebm-vol-inv(avol0), bleb0 ≠ nobuffer → avol1[bleb0.leb].mapped? ∧ bleb0.leb < # avol1 ∧ bleb0.isbuf?, bleb0 ≠ nobuffer → bleb0.leb < # avol1 ∧ wbuf-cons(mkwbuf(buf, m4, m3), avol0[bleb0.leb], false), bleb0 = nobuffer ∨ m3 = 0, bleb0 = nobuffer ∨ is-aligned(# avol1[bleb0.leb].data, EB_PAGE_SIZE) ⊦ avol1[n] = avol0[n], bleb0 = buffered(m5), bleb0 = nobuffer, n = m5

Rule argument

fma: bleb0 = nobuffer

Additional information

Used simplifier rules: ⊦ nobuffer ≠ buffered(m); (s)% ⊦ abs(avol0, nobuffer, wbuf, avol1, rofs) ↔ avol0 = avol1; (s) Used formulas: bleb0 = nobuffer
