Proof step 31 from proof transitivity (previous step)

key1.ino < ino1, ino < ino1, dentrykey(ino1, str) < key1, key1.ino ≤ ino ⊦ key1.data? ∧ ino = key1.ino ∧ ino0 < key1.part

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 32:
⊦ dentrykey(ino, str) < key ↔ ino < key.ino ∨ key.dentry? ∧ ino = key.ino ∧ str < key.name ∨ key.data? ∧ ino = key.ino
Proof step 33:
ino < ino1, key1.ino < ino1, key1.ino ≤ ino, ino1 < key1.ino ∨ key1.dentry? ∧ ino1 = key1.ino ∧ str < key1.name ∨ key1.data? ∧ ino1 = key1.ino ⊦ key1.data? ∧ ino = key1.ino ∧ ino0 < key1.part

Rule argument

spec: key-order-def name: dentrykey-less seq: ⊦ dentrykey(ino, str) < key ↔ ino < key.ino ∨ key.dentry? ∧ ino = key.ino ∧ str < key.name ∨ key.data? ∧ ino = key.ino subst: [key, str, ino] → [key1, str, ino1] flags: <all paths>
