Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

spec: abstract-file name: elim seq: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content) subst: [af, m, md, m0, content] → [(ino = entries0[str] ⊃ mkfile(m2, md, m11, content1) ;mkfile(m12, md7, m13, content0) ), m14, md8, m15, content2]

Additional information

Used simplifier rules: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content); (elim) Used terms: (ino = entries0[str] ⊃ mkfile(m2, md, m11, content1) ;mkfile(m12, md7, m13, content0) ), m14, md8, m15, content2
