Proof step 2 from proof inv-unmap (previous step)

# lpt = # avol, m < # avol, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟪awbuf_unmap#(m, adr, m0, nx, lpt, ns, bleb, isbuf; avol)⟫ (awbuf-inv(avol, bleb) ∧ # lpt = # avol), buffered(m) = bleb

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
# lpt = # avol, buffered(m) ≠ bleb, m < # avol, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟪awbuf_unmap#(m, adr, m0, nx, lpt, ns, bleb, isbuf; avol)⟫ (awbuf-inv(avol, bleb) ∧ # lpt = # avol)
