Installed.
I started a couple of weeks ago to try to create a version of this
patch for the 3.1 branch. However, a number of things are different
and I haven't had time to work out the bugs.
The current patch is quite a major rewrite. I was wondering if a
less invasive patch could be developed for the branch. The main
problem seems to be in the conversion of vax D floats. The other
option is to not use the emulator with the vax port.

For 3.2.1 - it's much too late to put this sort of thing in for
3.1.1/3.2.0 - I think that whatever patch you can come up with, as
long as it only affects the VAX, will be acceptable.

Both F and D floats are wrong for VAX. F float is less obvious
because the field sizes are the same as for IEEE, but the exponent
bias is different.
A VAX-only solution would be to lift the new stuff from the trunk
real.c (basically the *ieee* functions) and use them only condional on
vax float format, leaving all the others platforms alone.
This is not a good time for me to try to spend time on that,
unfortunately...

OK, I think the safest approach is to revert to not using the
emulator on the 3.1 (3.2) branch. Cross compilers won't work
properly but this has been the case for years.

As I started digging into your patch, I realized how much work
was involved in developing and testing it.
Thanks,
Dave

Neither of us has write access. Could someone who does have write
access do the checkin? I verified (yesterday) that real.c is
unchanged since I generated the patch, so there shouldn't be any
patch mismatch issues.
