Use of dynamic translation to collect and exploit run-time information in an optimizing compilation system

摘要

Dynamic translation is used to produce profile information used to optimize object code for an application. In order to produce optimized object code for the application, source code for the application is compiled to produce first object code for the application. The first object code is used in the generation of profile information about the application. This is done by dynamically translating the first object code to produce second object code. The second object code includes profiling code which, when executed, produces the profile information. The second object code is executed to produce the profile information. The source code for the application is recompiled to produce the optimized object code. The recompiling includes using the profile information in the production of the optimized object code.
