Proof step 3 from proof ubi-io-inv-fillcount0 (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, 0, false), n < # apebs, ubi-io-inv(apebs), ubi-io-peb-inv(mkpeb(aehdr, avhdr, buf, 0, false)) ⊦ buf = mkempbuf(LEB_SIZE)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ ubi-io-inv(apebs) ↔ (∀ n. n < # apebs → ubi-io-peb-inv(apebs[n]))
Proof step 5:
apebs[n] = mkpeb(aehdr, avhdr, buf, 0, false), n < # apebs, ubi-io-peb-inv(mkpeb(aehdr, avhdr, buf, 0, false)), ∀ n. n < # apebs → ubi-io-peb-inv(apebs[n]) ⊦ buf = mkempbuf(LEB_SIZE)

Rule argument

spec: ubi-io-inv name: inv seq: ⊦ ubi-io-inv(apebs) ↔ (∀ n. n < # apebs → ubi-io-peb-inv(apebs[n])) subst: [apebs] → [apebs] flags: <all paths>
