Flexible Instrumentation for Software Dynamic Translation

Software dynamic translators have been used for many purposes, such as dynamic code optimization, profiling, and security. Many of these applications need to instrument a program's binary code to gather run-time information about the program. Such instrumentation is varied, with different software dynamic translator applications requiring different kinds of information. Hence, there is a need for a flexible mechanism for information gathering and instrumentation in software dynamic translators. In this paper, we describe our approach to providing flexible instrumentation. We also experimentally evaluate our approach and investigate its overhead and demonstrate its flexibility for different software dynamic translation systems
