 Forums >>  Debuggers  >>  GDB Two's Complement offsets

Topic created on: April 11, 2008 20:48 CDT by fuzzforfun .

Is there a way to have GDB print offsets as decimal instead of two's complement?

mov    %eax,0xfffffffc(%ebp)

to:

mov    %eax,-4(%ebp)

Or can you do this in a .gdbinit function?

I don't use GDB but....Remember that you might mislead yourself if you use automatic conversion to a certain type.

That hex value can mean multiple things...
It could be signed or unsigned.
-4 or 4294967292

Just keep that in mind.  Sorry I'm not actually telling what you asked for.  Just figured I'd remind you that data is just data and it's how we interpret it that gives it meaning.

you can have GDB disassemble in intel "set disassembly-flavor intel" that will probably look nicer to you
