Proof step 5 from proof abs-nodes-bothcrash-prefix (previous step)

buf0.align↓ + buf = (buf0 + buf1).align↓, abs-nodes(buf0.align↓ + buf, 0, x1, lax1, boolvar1), abs-nodes(buf0.align↓, 0, x0, lax0, boolvar0) ⊦ x0 ⊑ x1 ∧ lax0 ⊑ lax1

And obtained the following new goals

Rule argument

spec: <toplevel> name: abs-nodes-prefix-h seq: ⊦ abs-nodes(buf0, m, x0, lax0, boolvar0) ∧ abs-nodes(buf0 + buf1, m, x1, lax1, boolvar1) → x0 ⊑ x1 ∧ lax0 ⊑ lax1 subst: [buf0, m, x0, lax0, boolvar0, buf1, x1, lax1, boolvar1] → [buf0.align↓, 0, x0, lax0, boolvar0, buf, x1, lax1, boolvar1]

Additional information

Used terms: buf0.align↓, 0, x0, lax0, boolvar0, buf, x1, lax1, boolvar1
