Proof step 7 from proof encode-contract (previous step)

size-aligned(a, ENCODED_ELEM_ALIGNMENT) < encoding-size(a), # buf < n + encoding-size(a), n + size-aligned(a, ENCODED_ELEM_ALIGNMENT) ≤ # buf ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
⊦ size-aligned(a, m) = align↑(encoding-size(a), m)

Rule argument

spec: <toplevel> name: size-aligned seq: ⊦ size-aligned(a, m) = align↑(encoding-size(a), m) subst: [m, a] → [ENCODED_ELEM_ALIGNMENT, a] flags: <all paths>

Additional information

Used simplifier rules: ⊦ ENCODED_ELEM_ALIGNMENT ≠ 0; (s)%m ≠ 0 ⊦ align↑(n, m) < n ↔ false; (s) Used terms: ENCODED_ELEM_ALIGNMENT, a
