Hi all,
I’m thinking to update gdb to recent version.
Are there any concerns?
What should I know? Any dependencies which force us to stick to 7.6?
The features I’m aiming are:
1) `offset` support in add-symbol-file, can be used to provide kaslr_offset to gdb
2) remove-symbol-file - can be used to remove original symbols after finding kaslr_offset
Thanks for raising this. I have recently started work (mainly from
RHEL p-o-v) to evaluate crash porting to gdb-10.1 as we need right now
to keep some additional patches in upstream crash code to help fix
issues, for example:
- ppc64le enablement,
- other fixes picked from gdb upstream which fix some issues with gdb-7.6
There is a case for using gdb-10.1 to avoid such patches. However, I
am still in the very preliminary stage of the evaluation.
My high-level goal is to give gdb more resources (access to
registers, memory, machine info - such as number CPUs), so we can use useful gdb commands
as:
bt, frame, info locals
Makes sense.
Let me know if you need any help from my side for the same. I plan to
try some more for the porting (from RHEL-p-o-v) this weekend - maybe I
will come back with more updates on the same early next week.
Thanks,
Bhupesh
