Fwd: Re: [patch] Add support for ARMv7M devices.

[Jonathan Larmour <jifl at eCosCentric dot com>]

Over a year ago, after discussion and some helpful pointers from Daniel, I
submitted this patch:

http://sourceware.org/ml/gdb-patches/2010-11/msg00142.html

Unfortunately it fell by the wayside.

This issue is coming to a head for the eCos project as we are updating our
ARM toolchain (we avoid the bleeding edge). However that means we really
need GDB to preserve backward compatibility, which it presently fails to do.

We don't want to break backward compatibility with installed GDB stubs,
and the XML solution is complicated for users, opaque, not really suitable
for Eclipse (although there may be proprietary plugins around which try to
solve this, that isn't relevant for public GDB). Most importantly the
attached patch should flexibly work everywhere, and not break anyone's
compatibility. And furthermore, it allows us a clean migration path to the
changed 'g' packet length.

So I'm attaching an updated version of the patch for current GDB trunk. If
it helps, I do have an FSF assignment and, from prehistory, commit
permissions.
