Proof step 5 from proof refine-iget (previous step)

err = err0, inode = p_inode, orphans(fs, ri).inodes?, fo.inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), inodekey(ino) ∈ ri, asynced → boolvar ⊦ [aubifs_iget#(ino, ri, fi, orphans(fs, ri), fo, fs, log, boolvar; inode, err)] ⟨afs_iget#(ino, abs-dirs(fs, ri), abs-files(fs, ri), asynced; p_inode, err0)⟩ ((asynced → boolvar) ∧ inode = p_inode ∧ err = err0)

User applied rule call right

And obtained the following new goals

Proof step 6:
boolvar0 ↔ boolvar, err = err0, inode = p_inode, ro = orphans(fs, ri), fo.inodes?, orphans(fs, ri).inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), inodekey(ino) ∈ ri, asynced → boolvar ⊦ [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] ⟨afs_iget#(ino, abs-dirs(fs, ri), abs-files(fs, ri), asynced; p_inode, err0)⟩ ((asynced → boolvar) ∧ inode = p_inode ∧ err = err0)

pos: right 1

Additional information

Used simplifier rules: aubifs_iget#(INO, RI, FI, RO, FO, FS, LOG, CSYNCED; INODE, ERR) {if pre-iget(INO, FS, RI) then let EXISTS = ? in {ERR := ESUCCESS; aubifs_iget_check# (INO, RI, FI, RO, FO, FS, LOG, CSYNCED; EXISTS, INODE, ERR)} else abort };
