Springer Series in Solid-State Sciencesary to traditional JIT machines, a trace compiler works on only part of the source program, normally a linear path inside a heavily executed loop. Because the trace is compiled during the interpretation of the source program the JIT compiler has access to runtime values. This observation gives the c

Basics of Semiconductor and Spin Physics,s. One such problem is caused by the copy semantics of .. Existing . systems rely on reference-counting schemes to create copies only when a shared array representation is updated. This reduces array copies, but requires runtime checks..We present a staged static analysis approach to determine when

In this paper we present an assignment approach with integrated copy coalescing, which maps the problem to the Partitioned Boolean Quadratic Problem (PBQP). Compared to the state-of-the-art

In this paper, we use two types of method summaries (callee and caller) to improve the performance of an interprocedural flow- and context-se

Spin trapping by nitrosoalkanesng instructions from the instruction set and re-arranging them such that frequent instruction sequences are co-located in memory. We take these frequent instruction sequences from hot program traces of external programs and we report a maximum speedup by a factor of 1.142. Thus, interpreter instruct
