I am working with the Eclipse C Development Tools community to add a
feature that will group registers in the Register View of Eclipse.
Since embedded CPUs have lots of peripheral registers (50-100+) it is
getting a burden for the developer to keep scrolling the registry view
to find the right register. A grouping will make the user experience way
better.
Since the IDE is relying on the GDB for most of the device information I
was wandering if there is a similar MI/GDB command to obtain the name of
the groups and their registers association.
In our product we added such command "-data-list-register-groups". The
syntax of the command is: -data-list-register-groups
^done,register-groups=[{name="r0",group="GRP1"},{name="r8",group="GRP2"}
]
Sure! have you looked at the output from: (gdb) maint print register-groups as it should make a good starting point.
I suspect that the output should be more like: ...{name="r0",groups=["grp1","grp2",...]},... (the MI syntax police will quickly point out the exact syntax :-).
I think Alexiev is off to see Santa 'til January .. but
this is a not from a patch he dropped to the CDT mailing list it should give you a rough idea of his way of thinking. The part about a default "Main" group is probably CDT specific and there for backward compatibility.
