Why only some? Aren't shift- and logical operations part of all CPU architectures?
That's not direct access to a bit, IMO. Direct access would be an operation that would load into a register a certain bit, or another that would compare directly to a certain bit in a byte in memory (in one op). I have never seen it, though.
That would be rather inefficient opcodes I think, and I can't think of any circumstance where that would be neccesary. Perhaps that's why you don't see it.
I think you can get those things in small cpus for small code size. I'm just guessing. Microcontrollers, perhaps? I have heard fo that "feature" previously, but I never seen it. - -- Cheers, Carlos E.
