Abstract
A generalized on-line solution for achieving transparent binary optimization using pre-existing profiling facilities and virtual memory remapping of text regions. An optimization environment is initialized which comprises a debugger program, a profiling facility, and an optimizer. A running target program is attached to the debugger program, wherein the debugger program monitors process execution of the target program. Responsive to monitoring the running target program, profile data of the running target program is collected using the profiling facility. The profile data is provided to the optimizer, wherein the optimizer analyzes the profile data and existing code of the running target program. Responsive to a determination to optimize the existing code based on the profile data, optimized code is generated for the running target program. The optimized code is provided to the debugger program, wherein the debugger program inserts the optimized code into a virtual address space of the running target program.
