Abstract: In one embodiment, an indirect branch is detected in computer program code. The indirect branch calls one of a plurality of functions using a first register. In response, the computer program code is augmented to store an identifier of the indirect branch call in a second register, and the code for each of the plurality of functions is augmented to: determine whether an identifier for the function matches the identifier stored in the second register and render the first register unusable if the identifier for the function does not match the identifier stored in the second register.

Abstract: Techniques for an instruction for a Runtime Call operation are described. An example apparatus comprises decoder circuitry to decode a single instruction, the single instruction to include a field for an identifier of an opcode, the opcode to indicate execution circuitry is to execute a no operation when a runtime call destination equals a predetermined value; and execute an indirect call with the runtime call destination as a destination address when the runtime call destination does not equal the predetermined value. Other examples are described and claimed.
