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

pebs[m0] = mkpeb(buf, EB_PAGE_SIZE, false), avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪ubi_io_write_vidhdr#(m0, avhdr, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
pebs[m0] = mkpeb(buf, EB_PAGE_SIZE, false), m = EB_PAGE_SIZE, avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪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⟫ mtd-cons(pebs)

Rule argument

pos: right 1
