Multicodes: optimizing virtual machines using bytecode sequences

TL;DR: It is able to show that simple ahead of time analysis of VM and execution properties can help determine the suitability of code-copying for a particular VM before an implementation of code -copying is even attempted.

TL;DR: The research presented in this paper proposes a technique that combines some of the main benefits of JIT compilation, superoperators(SOs) and profile-guided optimization, in order to deliver a lightweight Java bytecode compilation system that achieves runtime performance similar to that of state-of-the-art JIT/AO systems, while having a minimal impact on runtime memory consumption.

TL;DR: This paper presents the framework and key optimizations of a JIT compiler designed for Intelpsilas J2ME virtual machine, namely XORP, for XScaletrade architecture, and describes the bytecode-based optimizations, e.g. bytecode inlining, Array Bounds Check Elimination, Null Pointer Check Eliminations, etc.

TL;DR: A maintainable enhancement of a highly optimizing compiler, GCC, that allows code-copying VMs to safely achieve speedup up to 3 times, 1.67 on average, over the direct interpretation.

TL;DR: In this article, the authors present a detailed overview of the Java Virtual Machine, including the internal structure of the class file format, the internal form of Fully Qualified Class and Interface names, and the implementation of new class instances.

TL;DR: The Java Virtual Machine as discussed by the authors is the technology that enables the Java 2 platform to host applications on any computer or operating system without rewriting or recompiling, and is the complete and definitive specification for the technology.

TL;DR: The paper describes the design and implementation of a hybrid translator/interpreter that employs superoperators, an optimization technique for bytecoded interpreters that builds an efficient implementation of the virtual machine in assembly language.

TL;DR: A platform independent analysis of the dynamic profiles of Java programs when executing on the Java Virtual Machine, and the results presented describe the dynamic instruction usage frequencies, as well as the sizes of the local variable, parameter and operand stacks during execution on the JVM.
