It’s not clear to me what you are asking. What does ‘clear reason about’ mean?
F2I and I2F are instructions that perform real conversions, they do not facilitate type re-interpretation of bit patterns. Since GPUs use the same 32-bit registers for floating-point and integer data, type-reinterpretation is for free (a no-op at machine code level).
BFE and BFI are integer instructions. Are you asking what their exact semantics are? PTX has instructions bfe and bfi that correspond to these machine instructions (one-to-one, best I know), see their descriptions in the PTX manual.
Are you asking whether there is a profiler metric that returns a count of texture instructions (TEX*)? I can’t find one. There are various texture related performance metrics which seem much more relevant to programmers optimizing code. A counter for texture instructions either does not exist in the hardware, or is not exposed in the profiler [possible reasons: nobody finds it useful, nobody has requested it, the HW counter is unreliable]
