Proof step 3 from proof fwd-buffered-mapped (previous step)

avol[n] = unmapped, n < # avol, awbuf-inv(avol, buffered(n)) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: awbuf-inv name: awbuf-inv-def seq: ⊦ awbuf-inv(avol, bleb) ↔ ¬ ¬ ( (∀ n. n < # avol ∧ avol[n].mapped? → # avol[n].data ≤ LEB_SIZE ∧ ( buffered(n) ≠ bleb → is-aligned(# avol[n].data, EB_PAGE_SIZE))) ∧ ( bleb ≠ nobuffer → bleb.leb < # avol ∧ avol[bleb.leb].mapped?)) subst: [bleb, avol] → [buffered(n), avol] flags: <all paths>

Additional information

Used simplifier rules: ⊦ buffered(m) = buffered(m0) ↔ m = m0; (s)% ⊦ nobuffer ≠ buffered(m); (s)% ⊦ buffered(m).leb = m; (s)% ⊦ aleb.mapped? ↔ (∃ buf. aleb = mapped(buf)); (as)% ⊦ unmapped ≠ mapped(buf); (s) Used terms: buffered(n), avol
