Abstract
Embodiments relate to optimizing an indirect call function. A compiler is provided to identify potential target functions and indicate the potential target functions in the program code. Additionally, the compiler determines and indicates 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. A linker can read the indication the compiler made in the program code and optimize the indirect call function.
