Rule argument

spec: icache-entry name: elim seq: ⊦ (boolvar ↔ ie.dirty) ∧ inode = ie.inode ↔ ie = mkientry(boolvar, inode) subst: [ie, boolvar, inode] → [cache_icache [m1, mkientry(false, mkinode(m1, md2, true, m3, m4, m)) ] [m5, mkientry(false, mkinode(m5, md3, true, 1, 0, 0)) ] [ino ], boolvar, inode]

Additional information

Used simplifier rules: ⊦ (boolvar ↔ ie.dirty) ∧ inode = ie.inode ↔ ie = mkientry(boolvar, inode); (elim) Used terms: cache_icache[m1, mkientry(false, mkinode(m1, md2, true, m3, m4, m))] [m5, mkientry(false, mkinode(m5, md3, true, 1, 0, 0)) ] [ino ], boolvar, inode
