Log pc and lr while emulating + guess lr symbol #9

Closed fabian-thomas closed 11 months ago

fabian-thomas commented 11 months ago

This adds more info to the output of -t, that is, logging the pc (the address of the function) and the lr. This makes debugging easier.

Also, a function is added that tries to guess the symbol of lr. We need to guess, since symbols only point to the beginning of the function. Guessing is thereby done, by just taking the first symbol that has a lower address than lr.

Hi Fabian,

Thank you for all the pull requests. I will take some time here, as I am a bit busy at the moment.

Is the helper doing the same as closest_symbol?

Then we should use that to avoid code duplication

Yes, absolutely. Should have checked... I'm gonna quickly fix this
