摘要： A system (450) and method (200) of operation for determining operational characteristics of a computer software program. An executable program having a plurality of executable blocks is loaded into memory (456). A parent process is loaded into a same address space in memory (456). Each entry point is determined (204). Entry point instructions are replaced with branches so the parent process (206). Execution of the executable program commences (208). When each entry point is reached, diagnostic code is selectively written into memory (211, 212). Execution is then continued (214). When run, the diagnostic code reports an operational characteristic of the executable program. Diagnostic code is written only for executable blocks about to be executed and based upon dynamic user input. Another embodiment (600) maintains a virtual register set and investigates operation of the computer software program by emulating the effect of the program on the virtual register set and memory. Emulation code blocks may be generated just prior to their execution or generated at one time for the complete computer software program.
