Proof step 3 from proof inv-write-data-wl (previous step)

pebs[m0].fill = 2 * EB_PAGE_SIZE, m0 < # pebs, is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), n ≤ # buf, n ≤ LEB_SIZE, ¬ pebs[m0].bad ⊦ ⟪ubi_io_write_data_wl#(m0, n, buf, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
pebs[m0] = mkpeb(buf0, m, boolvar), ¬ boolvar, m = 2 * EB_PAGE_SIZE, m0 < # pebs, is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), n ≤ LEB_SIZE, n ≤ # buf ⊦ ⟪ubi_io_write_data_wl#(m0, n, buf, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)

Rule argument

spec: peb name: elim seq: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar) subst: [peb, buf, m, boolvar] → [pebs[m0], buf0, m, boolvar]

Additional information

Used simplifier rules: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar); (elim) Used terms: pebs[m0], buf0, m, boolvar
