1. A method, comprising: executing an unintended 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 originally intended control transfer instruction and at least one code snippet of the plurality is a non-cached code snippet not found in a cache memory; and developing an instruction loading profile by monitoring instruction fetches relative to cache misses, where the cache misses are fetched instructions absent from the cache memory on the instruction fetch.
