Proof step 2 from proof is-encoded-rec-unique (previous step)

is-encoded-rec(vtbl0, buf) ⊦ is-encoded-rec(vtbl1, buf) ↔ vtbl0 = vtbl1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
# buf = # vtbl1 * (ENCODED_VOLID_SIZE + ENCODED_NAT_SIZE), # buf = # vtbl0 * (ENCODED_VOLID_SIZE + ENCODED_NAT_SIZE), is-encoded-rec(vtbl0, buf), is-encoded-rec(vtbl1, buf) ⊦ vtbl0 = vtbl1

Rule argument

Additional information

Used simplifier rules: is-encoded-rec-size: ⊦ is-encoded-rec(vtbl, buf) → # buf = # vtbl * (ENCODED_VOLID_SIZE + ENCODED_NAT_SIZE);
