Proof step 37 from proof inv-readdir (previous step)

dirs[ino0] = mkdir(m, md, # links(ino0, dirs), m1, entries), err = ESUCCESS, afs-cons(dirs, files), ispath(p0, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), pr(user, md), px-parent(user, p0, ROOT_INO, dirs, files), ino0 ∈ dirs ⊦ ⟪afs_readdir#(mkinode(ino0, md, true, # links(ino0, dirs), m1, m), dirs, files, asynced; strings, err)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 38:
dirs[ino0] = mkdir(m, md, # links(ino0, dirs), m1, entries), err = ESUCCESS, inode = mkinode(ino0, md, true, # links(ino0, dirs), m1, m), strings0 = strings, afs-cons(dirs, files), ispath(p0, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), pr(user, md), px-parent(user, p0, ROOT_INO, dirs, files), ino0 ∈ dirs ⊦ ⟪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⟫ true

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 };
