Proof step 9 from proof prepost-encode-lpt (previous step)

⊦ is-encoded(lpt, mkbuf(lptsize(# lpt, LEB_SIZE)), 0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 10:
⊦ is-encoded(lpt, buf, n) ↔ # buf = lptsize(# lpt, LEB_SIZE) ∧ (∀ m. m < # lpt ∧ m < n → is-encoded(lpt[m], subarray(buf, m * ENCODED_LPROPS_SIZE, ENCODED_LPROPS_SIZE)))

Rule argument

spec: encoding-lpt name: is-encoded seq: ⊦ is-encoded(lpt, buf, n) ↔ # buf = lptsize(# lpt, LEB_SIZE) ∧ (∀ m. m < # lpt ∧ m < n → is-encoded (lpt[m], subarray (buf, m * ENCODED_LPROPS_SIZE, ENCODED_LPROPS_SIZE))) subst: [n, buf, lpt] → [0, mkbuf(lptsize(# lpt, LEB_SIZE)), lpt] flags: <all paths>

Additional information

Used simplifier rules: ⊦ # mkbuf(n) = n; (s)% ⊦ ¬ m < 0; (s) Used terms: 0, mkbuf(lptsize(# lpt, LEB_SIZE)), lpt
