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. Mark
