User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: aubifs-base name: write-shift seq: # ax = # ndx ⊦ ¬ adr ∈ ax → fs[adr, nd][ax, ndx] = fs[ax, ndx][adr, nd] subst: [ndx, ax, nd, adr, fs] → [fs[ri[kx1]], ax0, fs[ri[key]], adr, fs] flags: <all paths>

Additional information

Used simplifier rules: replay-safe-write: ⊦ ¬ adr ∈ log → (replay-safe(log, fs[adr, nd], ri) ↔ replay-safe(log, fs, ri));% ⊦ # fs[ax] = # ax; (s)% ⊦ # ri[kx] = # kx; (s) Used terms: fs[ri[kx1]], ax0, fs[ri[key]], adr, fs
