Proof step 4 from proof inv-iget (previous step)

boolvar0 ↔ boolvar, fo.inodes?, ro.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, ro, fi, fo, log), inodekey(ino) ∈ ri ⊦ ⟪if pre-iget(ino, fs, ri) then let boolvar = ? in {err := ESUCCESS; aubifs_iget_check#(ino, ri, fi, ro, fo, fs, log, boolvar0; boolvar, inode, err)} else abort⟫ true

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 5:
boolvar0 ↔ boolvar, ro.inodes?, fo.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, ro, fi, fo, log), inodekey(ino) ∈ ri ⊦ ⟪let boolvar = ? in {err := ESUCCESS; aubifs_iget_check#(ino, ri, fi, ro, fo, fs, log, boolvar0; boolvar, inode, err)}⟫ true

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ pre-iget(ino, fs, ri) ↔ valid-ino(ino, fs, ri); (s)% ⊦ valid-ino(ino, fs, ri) ↔ inodekey(ino) ∈ ri; (s)
