Proof step 1 from proof valid-wl-write-valid (conclusion)

m < # apebs, # apebs = # wlar ⊦ apebs[m] = mkpeb(aehdr, avhdr, buf0, m0, boolvar0) ∧ valid-peb(mkpeb(aehdr, avhdr, buf0, m0, boolvar0)) ∧ valid-peb(mkpeb(aehdr, avhdr, buf1, m1, boolvar1)) ∧ wlar[m] = wl-entry(m2, used) → (valid-wl(apebs[m, mkpeb(aehdr, avhdr, buf1, m1, boolvar1)], wlar) ↔ valid-wl(apebs, wlar))

System applied rule normalize

And obtained the following new goals

Proof step 2:
# apebs = # wlar, apebs[m] = mkpeb(aehdr, avhdr, buf0, m0, boolvar0), wlar[m] = wl-entry(m2, used), m < # apebs, valid-peb(mkpeb(aehdr, avhdr, buf0, m0, boolvar0)), valid-peb(mkpeb(aehdr, avhdr, buf1, m1, boolvar1)) ⊦ valid-wl(apebs[m, mkpeb(aehdr, avhdr, buf1, m1, boolvar1)], wlar) ↔ valid-wl(apebs, wlar)
