A framework for user-directed profile-driven optimizations

[0021] According to an example embodiment, an architecture may facilitate user-directed profiling-driven optimization by allowing a software developer to profile selected portions of an application and directing the compiler to perform value-profiling transformations based on the profiling results, such as figure 2 shown in . User-defined information can be included in both instrumentation and optimizing compilation of the feedback loop.

[0022] An example method for using profiling to obtain application-specific, preferred parameter values ​​for an application begins by identifying a parameter for which an application-specific value is to be obtained (301), such as image 3 shown in . The enhancement code can then be parsed (302) for application specificity of parameters. In some embodiments, the code to be enhanced may be application code. In other embodiments, the code to be enhanced may be a library used by the application code. This parameter is then parsed specificall
