Flag: Tornado! Hurricane!

 Forums >>  IDA Pro  >>  Zero Flag Register not available during debugging?

Topic created on: August 2, 2010 07:47 CDT by airhog .

I am working on a project, my first one outside of a tutorial, and I have ran into a stumbling block. When I am debugging the program, none of the Flag Registers show up in the registers view. I'm targeting the MetaPC, and the generic assembler. I checked all of the settings for the kernel, and processor, and they are all set to the standard settings. Any idea why the flags wouldn't show up?

No clue, I can only say that in x86 mode (I mean, intel) the flags are shown, and you can modify them as program is debugged.

Hey there ..

Well i don't know exact reason .. but i like to share one situation where we didn't get registers values during running programm..

Whenever i debug the programm .. and it stuck in any function call where it has to taken the input like .. call to "scanf" function .. until i will not give input , it will not shown the updated registers value ..

I m not sure ... may be your programm also waits for input from keyboard .. WILD GUESS ..
