Just FYI.

Mark, can something be done about the three externs in amd64fbsd-nat.c?

Thanks.

However, I think these 2 remappings are gross:

> +@V@/gdb/amd64fbsd-tdep.c @V@/gdb/x86fb-tdep.c
> +@V@/gdb/amd64fbsd-nat.c @V@/gdb/x86fb-nat.c

Up until now, I was trying to preserve at least the few first letters
of the original name, so that a reasonable person could have a chance
of deducting the original name from the butchered one.  The above
goes a long way toward breaking that.

So I suggest the following instead:

> +@V@/gdb/amd64fbsd-tdep.c @V@/gdb/amd64f-tdep.c
> +@V@/gdb/amd64fbsd-nat.c @V@/gdb/amd64f-nat.c

Or are these already taken?

I'll change it.

Mark, should the original files be called x86-64-*?

No, he mentioned in his original posting that the FreeBSD port (like
the architecture, now) is called amd64.

The function was cut/paste from the i386-linux-nat.c, so not me.  I'd 
better fix it's portability problems though.

Exactly how old's the patch?  You should just push these out.

Right, not accusing.  But this is part of moving the code from -nat to
-tdep.  To be fair, I noticed it when reading your patch, but mine has
the same bug :)

Sending dozens of patches to the list has, historically, not done the
slightest bit of good.  Lately, sending single patches and repeated
reminders hasn't either.  I'm too frustrated to add another patch to
the list I have to ping every month.

When my outstanding patches are approved or at least responded to, then
I will send more.

I don't suppose you have any plans to framify MIPS?  One of my
least-ready-for-submission patches adds signal handler unwinding for
mips-linux; it's hideous, and with the new frame code it would be much
cleaner.

All the files for that architecture should be called x86-64-* xor amd64-*.

Sure!  I fixed those earlier today :-).

Considering your concerns about amd64 vs. x86-64 in the naming of the
files: my main motivation for not using x86-64 is that it's a PITA to
type the latter.  I'm even considering renaming the file that were
already present, just to make my life easier.  I won't do this without
discussing it with Michal and Andreas though.

True.  On the other hand, having to and remembering to grep for both 
amd64 and x86_84 in x86-64* and amd64* is also a pain.  The combined 
projects might want think about a jumbo re-name.

Since everyone objected, I've changed things so that the amd64 files get 
contracted to a64 :-)

committed to 6.0 and mainline,
