Proof step 4 from proof crash-neutral-gc (previous step)

fs0 = fs, log0 = log, fo.inodes?, ro.inodes?, log-cons(log, fs), ri-cons(ri, fs), ri-inj(fi), ri-inj(ri) ⊦ ⟨if ri-cons(ri, fs) then {aubifs_core_gc_copy#(; ri, fs, log); aubifs_core_gc_drop#(ri, log; fs); boolvar := ?} else abort⟩ (boolvar ∧ fs0 = fs ∧ log0 = log)

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 5:
fs0 = fs, log0 = log, ro.inodes?, fo.inodes?, log-cons(log, fs), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟨aubifs_core_gc_copy#(; ri, fs, log); aubifs_core_gc_drop#(ri, log; fs); boolvar := ?⟩ (boolvar ∧ fs0 = fs ∧ log0 = log)

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ ri-cons(ri, fs) → ( ri-cons(ri0, fs0) ↔ (∀ key. (key ∈ ri → ri[key] ∈ fs ∧ key-cons(key, fs[ri[key]])) → key ∈ ri0 → ri0[key] ∈ fs0 ∧ key-cons(key, fs0[ri0[key]]))); (ss)
