Abstract
There is provided input circuitry to receive input data. Output circuitry outputs a sequence of instructions to be executed by data processing circuitry. Generation circuitry performs a generation process to generate the sequence of instructions using the input data with at least some of the instructions being grouped into functions. The sequence of instructions comprises an indirect control flow instruction comprising a field that indicates where a target of the indirect control flow instruction is stored. The target is an entry point to one of the functions and the generation process causes at least one of the instructions in the sequence of instructions to store a state of control flow speculation after execution of the indirect control flow instruction.
