Abstract
Embodiments relate to using a local entry point with an indirect call function. More specifically, a linker is provided to generate at application modules that at least partially defines an indirect function call configuration. The linker loads a first address of a function by using a first symbolic reference, and determines that the function pointer value of the first symbolic reference is solely used to perform indirect calls in the same application module, e.g. local-use-only. The linker indicates that the first symbolic reference can be resolved using the local entry point associated with the function, and performs that indirect function call exclusively through the first symbolic reference, thereby reducing execution of operations.
