Subject: [PATCH] Explicitly put registers in the general group for ARM
Date: Mon, 02 Mar 2020 17:59:00 -0000 [thread overview]
Message-ID: <20200302175915.176614-1-cbiesinger@google.com> (raw)
This seems like the right thing per the documentation:
https://sourceware.org/gdb/current/onlinedocs/gdb/Target-Description-Format.html#Target-Description-Format
"If no group is specified, GDB will not display the register in
info registers."
but should also help with this issue:
https://sourceware.org/ml/gdb-patches/2020-02/msg01038.html]
Note that "set tdesc filename features/arm/arm-core.xml; maint print c-tdesc"
prints an empty target description both before and after this change,
so I just manually edited the .c file to specify the group.
gdb/ChangeLog:
2020-03-02 Christian Biesinger <cbiesinger@google.com>
* features/aarch64-core.c (create_feature_aarch64_core): Put all
registers in the "general" group.
* features/aarch64-core.xml: Likewise.
* features/arm/arm-core.c (create_feature_arm_arm_core): Likewise.
* features/arm/arm-core.xml: Likewise.
