Proof step 3 from proof eq-io-readdir (previous step)

⟨afs_readdir#(p_inode, dirs1, files1, asynced; strings, err)⟩ (strings = strings0 ∧ err = err0) ⊦ ⟨afs_readdir#(p_inode, dirs1, files1, boolvar0; strings, err)⟩ (strings = strings0 ∧ err = err0)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
⟨afs_readdir#(p_inode, dirs1, files1, asynced0; strings, err)⟩ (strings = strings1 ∧ err = err0), asynced ↔ boolvar0, dirs = dirs1, files = files1, inode = p_inode, strings0 = strings ⊦ ⟨if pre-readdir(inode.ino, dirs, files) then {{strings0 := dom dirs[inode.ino].entries; err := ESUCCESS} or {choose strings with true in strings0 := strings; fail#(; ; err)}} else abort⟩ (strings0 = strings1 ∧ err = err0)

Rule argument

pos: right 1

Additional information

Used simplifier rules: afs_readdir#(INODE, DIRS, FILES, ASYNCED; NAMES, ERR) {if pre-readdir(INODE.ino, DIRS, FILES) then { {NAMES := dom DIRS[INODE.ino].entries; ERR := ESUCCESS} or {choose NAMES0 with true in NAMES := NAMES0; fail#(; ; ERR)}} else abort };
