The research focuses on the design and implementation of a framework, called the ADaptive Object RE-optimization (ADORE) system, to evaluate the effectiveness of dynamic binary re-optimization, and to study the interaction between architecture/micro-architecture and a dynamic binary re-optimizer. The topics studied include: efficient profiling techniques; runtime hot region selection and formation; light-weight runtime optimizations; code patching and region linking techniques; architectural and micro-architectural support for dynamic binary optimization; and runtime specialization and value profiling. The first implementation of the ADORE system will be based on two different implementations of the IA-64 architecture, the Itanium and the McKinley. The performance of application code optimized for Itanium will be tested on McKinley using the ADORE system.
