FYI,

I've committed the attached.  I get the error:

In file included from /home/scratch/GDB/src/gdb/x86-64-tdep.c:30:
/home/scratch/GDB/src/gdb/x86-64-tdep.h:27: sys/reg.h: No such file or

when trying to build an x86_64-linux-gnu target.

enjoy,
Andrew

I fear you applied a broken patch by Michal.  Has this been fixed?
Michal, can you test whether the CVS version works now?

I'd really like to see x86-64 working - and not as maintaince only.

Thanks,
Andreas

File sys/reg.h comes from x86-64 glibc sources and yes, using my
crosscompiler it compiles without problems for --host=x86-64 and 
--target=x86-64...
For --target=x86-64 and --host i686-... it may not work since headers 
are different. I'll try to solve it.

x86-64-tdep.h should definitely *not* include <sys/reg.h>, or any
target header for that matter.  It should be possible to build a GDB
that can debug x86-64 stuff on any host.  Currently that's not
possible since there are problems with dwarfcfi.c, which doesn't
compile on a 32-bit host right now, which is a pity since it means I
cannot really help you with fixing the x86-64 bits.

Anyway, you should really try to test your build with --target=x86-64
on a totally different platform, e.g. *BSD on a sparc.

Anyway, I think the attached patch solves the <sys/reg.h> problem.  It
shouldn't break your x86-64 target, but I'm not entirely sure.  Can
you test it for me?

Mark

And what about including the contents of sys/reg.h directly into 
x86-64-tdep.h? That should help as well, or not?

You should first ask yourself why <sys/reg.h> is needed in target
dependent (but host independent) code.  As I understand it,
<sys/reg.h> provides the indices by which registers may be found in
the data structures used to communicate the register's contents to/from
ptrace().  It seems to me that this information is of absolutely no
use when building a cross debugger (to x86-64), but is of vital
concern in the implementation of a native debugger.  Therefore,
<sys/reg.h> should included in the appropriate *-nat.c file instead.
