Including a .c file is perhaps a bit unorthodox, but this really is
the most elegant way I can think of to solve the issue with the
upcoming 64-bit Solaris 10.

I had considered such an approach but decided against it on the grounds of
lack of any precedent in GDB for one .c file to include another.

Why not have 368-sol2-nat inherit i386v4-nat's target vector?

Why not have 368-sol2-nat inherit i386v4-nat's target vector?
There's nothing there to inherit :-(. I'm still thinking about the
proper way to regset-ize fill_gregset(), fill_fpregset(),
supply_gregset() and supply_fpregset() in relation to the SVR4-like
/proc filesystem.
Oh, and I'm slowly beating the /proc support into shape such that I
can it can be inherited. Will take some time though before this
becomes reality.
Cheers,
Mark

Sounds like something Joseph could help with. He's the one with the
immediate desire to get sol10/amd64 supported.
What we're not going to add is screwed up #include inheritance, can you
revert that?

Damn. I'd hoped I could get away with that. Well, here's a different
approach. Spreads the logic over two files so it becomes a bit more
difficult to keep things in synch.

What ever.
I'd recommend the strategy I took for inf-ptrace, cut your losses and
start again. Create inf-procfs and from there inf-svr4 and finally the
solaris stuff you need.

Based on the latest CVS version after this patch, here is another version
of the AMD64 Solaris 10 patch. It is still based on the existing IA32
Solaris configuration, and on the principle of not mixing different
changes it does not attempt to address any pre-existing conditions
associated with that configuration. I think it will in fact be
straightforward to get rid of use of i386v4-nat.c on Solaris, using the
functions from i386-tdep.c (i386_supply_gregset, i386_collect_gregset)
instead; I also think doing so is independent of this patch (and I can
only test on Solaris 10 prerelease, not previous releases of IA32 Solaris
which are supported by GDB).
