## Abstract Optimizations performed at link time or directly applied to final program executables have received increased attention in recent years. This paper discusses the discovery and elimination of redundant load operations in the context of a linkβtime optimizer, an optimization that we call
WESSELS considered in [8] cut elimination in a Gentzen-style &-calculus without equality. But MINC pointed out in [6] that the proof in [8] is defective and mentions that the cut elimination theorem in a modified system can be proved model-theoretically. The work in 3 1, perhaps, carries out exactly
In this article, a cut-free system TLMΟ 1 for infinitary propositional modal logic is proposed which is complete with respect to the class of all Kripke frames. The system TLMΟ 1 is a kind of Gentzen style sequent calculus, but a sequent of TLMΟ 1 is defined as a finite tree of sequents in a standar
