Rule argument

spec: ablock-store-inv, inst: index-store name: prefix-refl seq: ⊦ inv(istore) → istore ⊑ istore subst: [istore] → [remove-refsize0(istore2)] flags: <all paths>

Additional information

Used simplifier rules: ⊦ inv(istore) → inv(remove-refsize0(istore)); (ss) Used terms: remove-refsize0(istore2)
