Proof step 85 from proof refine-write-vidhdr (previous step)

# buf2 = EB_PAGE_SIZE, apebs[m2] = mkpeb(aehdr, empty, buf0, m1, false), pebs[m2] = mkpeb(buf1, EB_PAGE_SIZE, false), aehdr.valid?, m2 < # pebs, m2 < # apebs, abs(pebs, apebs), abs-peb(mkpeb(buf1, EB_PAGE_SIZE, false), mkpeb(aehdr, empty, buf0, m1, false)), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err⌋ ⊦ ⟨aubi_io_write_vidhdr#(m2, avidhdr(v, m, m0, m3, m4); apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 86:

Used simplifier rules: aubi_io_write_vidhdr#(PNUM, AVHDR; APEBS; ERR) {if ubi-io-write-vidhdr-pre(PNUM, AVHDR, APEBS) then {fail_or_success#(; ; ERR); if ERR = ESUCCESS then APEBS[PNUM].vidhdr := AVHDR else choose AVHDR with ¬ AVHDR.valid? in APEBS[PNUM].vidhdr := AVHDR} else abort };
