Proof step 437 from proof inv-write_inode (previous step)

icache[m] = mkientry(boolvar, inode), err = ESUCCESS, afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ icache, m ∈ files ⊦ ⟪icache_set#((inode.meta:= md).size:= m2, true; err, icache)⟫ (icache-cons(icache, dirs, files) ∧ synced(dirs, icache, pcache))

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 438:
asynced ↔ true, icache[m] = mkientry(boolvar, inode0), err = ESUCCESS, inode = (inode0.meta:= md).size:= m2, afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ files, m ∈ icache ⊦ ⟪icache[inode.ino] := mkientry(asynced, inode)⟫ (icache-cons(icache, dirs, files) ∧ synced(dirs, icache, pcache))

Rule argument

pos: right 1

Additional information

Used simplifier rules: icache_set#(INODE, DIRTY; ERR, ICACHE) {ICACHE[INODE.ino] := mkientry(DIRTY, INODE)};
