Proof step 16 from proof inv-write-echdr (previous step)

# buf1 = EB_PAGE_SIZE, pebs[m0] = mkpeb(buf0, 0, false), aehdr.valid?, m0 < # pebs, is-encoded(echdr(aehdr.ec), buf1), mtd-cons(pebs) ⊦ ⟪mtd_asm_write#(m0, 0, 0, EB_PAGE_SIZE, buf1; pebs; err)⟫ mtd-cons(pebs)

User applied rule insert program lemma

And obtained the following new goals

Proof step 17:
mtd-cons(pebs), m < # pebs, ¬ pebs[m].bad, pebs[m].fill ≤ m0, m0 + n ≤ PEB_SIZE, n0 + n ≤ # buf, is-aligned(m0, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE) ⊦ ⟪mtd_asm_write#(m, m0, n0, n, buf; pebs; err)⟫ mtd-cons(pebs)

Rule argument

spec: mtd-asm name: inv-write seq: mtd-cons(pebs), m < # pebs, ¬ pebs[m].bad, pebs[m].fill ≤ m0, m0 + n ≤ PEB_SIZE, n0 + n ≤ # buf, is-aligned(m0, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE) ⊦ ⟪mtd_asm_write#(m, m0, n0, n, buf; pebs; err)⟫ mtd-cons(pebs) subst: [buf, n, n0, m0, m, pebs, err] → [buf1, EB_PAGE_SIZE, 0, 0, m0, pebs, err] flags: <all paths>
