Proof step 76 from proof refine-read (previous step)

# buf1 = # buf2, avols[default-volid][m2] = mapped(buf0, n1), m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), range=(buf1, 0, buf2, 0, n3), range=(buf1, n3 + n2, buf2, n3 + n2, # buf2 - n3 + n2), default-volid ∈ avols, m1 + n2 ≤ LEB_SIZE, n3 + n2 ≤ # buf2, ⌊err0⌋ ⊦ ⟨ebm_avol_read#(m2, m1, n3, n2, abs(avols[default-volid]); buf2; err1)⟩ (buf1 = buf2 ∧ err0 = err1)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 77:
# buf1 = # buf2, # buf2 = n0 + n3 + n2, avols[default-volid][m2] = mapped(buf0, n1), m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), range=(buf1, n3 + n2, buf2, n3 + n2, n0), range=(buf1, 0, buf2, 0, n3), default-volid ∈ avols, n3 + n2 ≤ # buf2, m1 + n2 ≤ LEB_SIZE, ⌊err0⌋ ⊦ ⟨ebm_avol_read#(m2, m1, n3, n2, abs(avols[default-volid]); buf2; err1)⟩ (buf1 = buf2 ∧ err0 = err1)

Rule argument

spec: nat name: elim-sub seq: n ≤ m ⊦ n0 = m - n ↔ m = n0 + n subst: [m, n, n0] → [# buf2, n3 + n2, n]
