Bug ID: 28556
Summary: sim: arm: crashing when generating core
Product: gdb
Version: 11.2
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: fredrik.hederstierna@securitas-direct.com
Target Milestone: ---
Created attachment 13764
--> https://sourceware.org/bugzilla/attachment.cgi?id=13764&action=edit
gdb_arm_sim_corefile.patch
The ARM simulator crashes if trying to generate a core file.
The ARM simulator does not support all registers, and also crashes in case of
entering zero length when trying fetching registers.
This patch adds IDs for D0-D31, then let any calling ARM simulator
implementation handle the results.
This patch allow gcore to also work in ARM simulator.
I tested 'gcore' on target sim for ARM on this, and it worked well on my tests.

Moving to sim component.
FWIW patches should go to gdb-patches for review, it's not usually
done in bugzilla.

Oops, sorry. I was updating a batch of Nick-assigned sim tickets.
I don't think there has been a lot of updates to arm's sim, so I wouldn't
expect it to be updated.
If you have a patch you'd like to post upstream, please send it go
gdb-patches@sourceware.org, as Tom pointed out.
