[RFC] Removing old core file sniffer support (affects FreeBSD/alpha)

[RFC] Removing old core file sniffer support (affects FreeBSD/alpha)

[Ulrich Weigand]

Hello,

after a transition period of more than a decade, we are really close to
actually moving all targets to the new tdep core file support (enabling
cross-debugging of core files and core file generation), and removing
the old-style long-deprecated native core file sniffer support.

I've posted (untested) patches moving four of the remaining targets

Linux/CRIS:
https://sourceware.org/ml/gdb-patches/2014-11/msg00707.html

GNU Hurd:
https://sourceware.org/ml/gdb-patches/2014-11/msg00708.html

Sparc Solaris:
https://sourceware.org/ml/gdb-patches/2014-11/msg00709.html

NetBSD/arm:
https://sourceware.org/ml/gdb-patches/2014-11/msg00714.html

Once those are in, there is just one more target remaining: FreeBSD/alpha.

I have an untested patch for this as well, but I'm wondering
whether this is worth it, as FreeBSD apparently has long stopped
supporting the Alpha platform (last available in FreeBSD 6.4,
which has been unsupported since end of 2010, if I'm reading
the web site correctly).

Given that, should we just remove FreeBSD/alpha support from
mainline GDB sources?

Bye,
Ulrich

Hi Ulrich,

I can confirm that alpha is not supported anymore by FreeBSD.
you could remove FreeBSD/alpha support from mainline GDB sources.

as soon as I can, I'll give a look to see if there are other
architectures not supported anymore by FreeBSD that could be safely
removed.

thanks!

best regards,
Luca Pizzamiglio
