   Dear Mark,

   Thank you for answering this. Yes I know that FPU regs are short ints
   (some of them) and I use the correct structs when I want to print
   them. However by adding to i386dgux.mt the file i387-tdep.o we have an
   immediate problem. It doesnt compile as it needs defs such as
   FCOFF_REGNUM etc ... so there the question what is what. 
   That is where my e-mail was targetting. For the story I have ported 
   gdb-4.18 to DG/UX and sources are in ftp.xfree86.org 
   pub/XFree86/3.3.6/binaries/DGUX-ix86/GDB_BETA. (if you have time
   take a look in the file there gdb/i386dgux-nat.c to verify that 
   I ma treating correctll the fpu regs). That port (fully working)
   never make it to the oficcial 5.0 for several reasons (mailnly I had not
   the time to request and sign copyright assignments for the *several* parts
   of gdb as bfd, etc etc ...!

I've taken a look at the stuff now.  However, since the FPU stuff is
rather different in 5.0, I don't think it's very useful to comment on
the way you handle things in your 4.18 based port.  If you follow my
advice you shouldn't have to do any significant manipulations on the
FPU state at all, and you could remove most of your home-grown FPU
stuff from i386dgux-nat.c.

It would be great if you could contribute your DG/UX port back to the
FSF.  Indeed we need a copyright assignment first.  If you can find
the time to do them, please do so ASAP.  They take some time being
processed.

Before we can integrate your DG/UX port into the official GDB tree,
some bits will have to be cleaned up.  First of all, you'll have to
base your work on the current development version.  Working from
snapshots is fine, but working from CVS is much more convenient.
Right now there is quite a bit of code duplication, and we'll have to
try to reduce that a bit.  You've alse added some DG/UX-specific
#ifdefs that will have to be eliminated.  I'll be happy to work
together on those issues.

   Now since I dont have CVS I would be greatfull if you send the files
   i387-nat.c and latest i386bsd.c ... 

Since you told me you downloaded a recent snapshot, you probably
already have them.  If you still need those files, drop me a mail.

Thats what I have done for the 5.0 release. I have integrate the routines
of i387-nat.c into i386dgux-nat.c (no i387-nat.c in 5.0) and remove most
of the floating point info handling code.

I wouldnt have any problem to give free the code to FSF. If this
worth something, I am declaring here publickly that the code in
ftp.xfree.org is *free* and anyone is welcome to integrate it as he/she
finds appropriate to future gdb releases. In gdb-5.0 port there are
two main additions/changes:
1) Full support for pthreads (I am desperate for that)
2) A much better port of bfd that allows also binutils-2.9.1 to work
for DG/UX unix and build gnu-as and most importantly gnu-ld.
However all these are done with #ifdefs DGUX ... (mainly in bfd).

After finishing release 5.0-port we can have a go on that. If anything
it will allow me to not deal anymore so extensively with the gdb
port (from the moment that the code will be integrated in say 5.01).
Only things from then and on will be "building issues" but these can
be dealt also by ordinary DG/UX users that will watch your list and
have a go to build gdb snapshots.

That is correct. I have seen the files now.

PS: I am cc'ing the gdb list but ... your server has some problem:

public.xfree86.org is certainly not the ORBS list ...
