1. A method, comprising: executing a sequence of code snippets in a processing circuit, each code snippet including at least one executable instruction including a control transfer instruction, wherein one or more of the code snippets includes a modified control transfer instruction different from an unmodified control transfer instruction and at least one code snippet of the sequence is a non-cached code snippet not found in a cache memory; detecting one or more instruction fetch cache misses in response to instruction fetches performed during execution of the sequence of code snippets, where an individual instruction fetch cache miss represents a fetched instruction absent from the cache memory for a corresponding instruction fetch of an executable code sequence; developing an instruction loading profile by monitoring instruction fetches relative to instruction fetch cache misses; and controlling an execution of at least one instruction based on the instruction loading profile.
