Proof step 5 from proof refine-write-vidhdr (previous step)

apebs[m] = mkpeb(aehdr, empty, buf, m0, false), aehdr.valid?, avhdr.valid?, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟪ubi_io_write_vidhdr#(m, avhdr, EB_PAGE_SIZE; pebs; err)⟫ ⟨aubi_io_write_vidhdr#(m, avhdr; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
apebs[m2] = mkpeb(aehdr, empty, buf, m1, false), m = EB_PAGE_SIZE, m0 = m2, avhdr.valid?, aehdr.valid?, m2 < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟪if m0 < # pebs ∧ avhdr.valid? ∧ ¬ pebs[m0].bad ∧ pebs[m0].fill = EB_PAGE_SIZE then let buf = mkbuf(m), vhdr = vidhdr(avhdr.vol, avhdr.leb, avhdr.sqn, avhdr.size, avhdr.checksum) in {encode_vidheader#(m, vhdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, m, 0, m, buf; pebs; err)} else abort⟫ ⟨aubi_io_write_vidhdr#(m2, avhdr; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)
