[bug#58971] [PATCH] gnu: Add avr-gdb.

[Kristian Lein-Mathisen]

Hi Chris and thanks for looking into this,

Your proposal is very reasonable. I wasn't sure what to write but I've given it a try in this replacement commit.

To be honest, I don't know why the AVR target isn't supported in the standard GDB

build and I haven't been able to figure out how to list all supported targets. I'm new to GDB in general so

I don't know if I'm the right person to do this writeup.

However, I'm looking at https://github.com/dwtk/dwtk (which I also intend to package for Guix if it's of interest), 

and the standard gdb gives me a bunch of error messages when I connect to dwtk's remote gdbserver. I'm guessing this

incompatibility applies to all gdbservers implemented for AVR chips. I haven't found much clarity of this in the GDB docs.

I presume this is the reason most distros package avr-gdb separately from gdb like we're doing here.

I've taken the "synopsis" from Arch Linux, removed unsupported languages from the description, and just 

mentioned that this is for the specific AVR microcontroller architecture. Please let me know if that's good enough.

Thanks,

K.

Hi Kristian,

This seems OK to me, although I don't know what this package is for?

Given this is inheriting from gdb, it'll have the same synopiss and
description:

  synopsis: The GNU debugger
  description: GDB is the GNU debugger.  With it, you can monitor what a program
  + is doing while it runs or what it was doing just before a crash.  It allows
  + you to specify the runtime conditions, to define breakpoints, and to change
  + how the program is running to try to fix bugs.  It can be used to debug
  + programs written in C, C++, Ada, Objective-C, Pascal and more.

So, I think if there is something different about this avr-gdb, it would
be good to specify a appropriate synopsis and description. Does that
make sense?

Thanks,

Chris
