Proof step 2 from proof inv-gc (previous step)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:

Additional information

Used simplifier rules: ⊦ ubifs-cons(fs, ri, ro, fi, fo, log) → log-cons(log, fs); (ss)% ⊦ ubifs-cons(fs, ri, ro, fi, fo, log) → ri-inj(ri); (ss)
