Proof step 35 from proof absexpt-pebs-write (previous step)

# vols[v0] = # avols[v0], avols[v0][m0] = mapped(buf0, m1), apebs[n, apeb][vols[v0][m0].pnum] = mkpeb(aehdr, avhdr, buf, m2, boolvar), vols[v][m] = ⌜n⌝ , apebs[vols[v0][m0].pnum] = mkpeb(aehdr0, avhdr0, buf0, m3, boolvar0), m0 < # avols[v0], m < # vols[v], valid-ebatbl(apebs, wlar, vols, n0), v0 ∈ avols, v0 ∈ vols, v ∈ vols, m3 ≤ m1, v0 ≠ v ∨ m0 ≠ m ⊦ vols[v0][m0] = unmapped, buf0 = buf ∧ m2 ≤ m1

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 36:
# vols[v0] = # avols[v0], apebs[m4] = mkpeb(aehdr0, avhdr0, buf0, m3, boolvar0), vols[v][m] = ⌜n⌝ , apebs[n, apeb][m4] = mkpeb(aehdr, avhdr, buf, m2, boolvar), avols[v0][m0] = mapped(buf0, m1), vols[v0][m0] = ⌜m4⌝ , m < # vols[v], m0 < # avols[v0], valid-ebatbl(apebs, wlar, vols, n0), v ∈ vols, v0 ∈ vols, v0 ∈ avols, m3 ≤ m1, v0 ≠ v ∨ m0 ≠ m ⊦ vols[v0][m0] = unmapped, buf0 = buf ∧ m2 ≤ m1

Rule argument

spec: ebaentry name: elim seq: ⊦ ebae ≠ unmapped → (m = ebae.pnum ↔ ebae = ⌜m⌝ ) subst: [ebae, m] → [vols[v0][m0], m4]

Additional information

Used simplifier rules: ⊦ ebae ≠ unmapped → (m = ebae.pnum ↔ ebae = ⌜m⌝ ); (elim) Used terms: vols[v0][m0], m4
