Abstract
Embodiments relate to using a local entry point with an indirect call function. A compiler is provided to determine and indicate in the program code that the function pointer value resulting from a non-call reference of a function symbol is solely used to perform indirect calls in the same module, e.g. local-use-only. The compiler loads an address of a function through use of a symbolic reference. When the compiler determines that the value employed by the symbolic reference is used exclusively to perform an indirect function call, the compiler proceeds to resolve a local entry point address of the function, thereby reducing a quantity of operations to be executed.
