Yea, that’s how program recording is done natively by GDB as well; it inserts a breakpoint after every single instruction, and records the the state of the program after every one. It’s mind–bogglingly slow, and the log files are gigantic. You generally have to limit it to record only a few instructions, generally tens of thousands rather than billions, in order to get any use out of it. At least if you can do it in hardware then it doesn’t have to be slow, even if the recorded state is still huge.
