 Forums >>  IDA Pro  >>  Labeling Multiple Use Memory Locations

Topic created on: March 16, 2007 06:32 CDT by bodzcount .

Hi,

I have the problem that the same memory location is used in different functions for different things, therefore they should have a different name as well. However I think this is not possible in IDA, or does anybody have a solution?

For now I have named the variable name1_or_name2 which is a little bit ugly.

regards,
bodz

I mostly call these variables "temp" or something like that. You can then add a multiline repeatable comment (hotkey: shift-semicolon):
"temp variable, used as
- blah
- blah2
..."

I just give them big long names as well. Would be interesting to come up with a way to swap names based on your current context. Maybe you can create some IDC or IDA Python scripts that you assign hotkeys and implement the following functionality:

- Create new context
- Add function to context
- Delete context
- Switch context
- Change name in current context

Then when you switch between contexts, the names could auto change.

My prefered solution is to create a union containing the various translations and then cast the memory/variable where its referenced with its appropriate meaning.
