            Bug ID: 31448
           Summary: [Feature Request] Register's bitfields MI Commands
           Product: gdb
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mi
          Assignee: unassigned at sourceware dot org
          Reporter: robert.pirvu at cyberthorstudios dot com
  Target Milestone: ---

I'm working on a new functionality for Eclipse to allow Register View to
display bitfields.

For this, I propose two GDB MI Command changes:

    1. A new command to return a list of bitfields' names, similar to
-data-list-register-name.

Command: -data-list-register-bitfield-name (regno) 
Response: ^done,register-bitfield-names=[{name="reg0",
bitfields=["A","B","C"]},{name="reg1", bitfields=["D","E"]}]

If regno(register's number) is specified then the response will contain only
the specified register.

    2. A new option "--with-bitfields" for -data-list-register-values to
include a list of bitfields' values. This option was suggested by Guinevere
Larsen to receive the necessary data and not change the default response of
this command. A similar approach can be used for the bitfields' names MI
Command as well if is a better implementation.   

Command: -data-list-register-values --with-bitfields
Respone:
^done,register-values=[{number="0",value="0x0",bitfields=[0,0,0]},{number="1",value="0x1",bitfields=[0,0]}]

Format of the response: 
[{number="regNo",value="regValue",bitfields=[bitVal1,bitVal2,bitVal3]}]

Initial thread of this
request:https://sourceware.org/pipermail/gdb/2024-February/051071.html

Any feedback regarding this feature is greatly appreciated and we are 
open to contribute to its implementation.
