Hi,
I apologize for the poor quality of the initial version of the patch that I
submitted. I think I may have also mangled it by not disabling the "smart
quotes" feature on my Mac before I pasted in the diff from the terminal window.
I intentionally did not use gmail for fear of adding word
nd to define. I'll keep
working on things and as soon as I have something that I think is in a
contributable state and doesn't generate bad code, I'll email it.
Best regards,
Jake

Amazingly enough, my patch worked well enough that my NetBSD VAX kernel built
with GCC 5.3 is no longer crashing. I feel pretty good about what I have so far
so here's the complete diff for both the C++ exception fix and the bad
condition codes optimizer bug. It should be good enough to check
f (GET_CODE (x) == PRE_DEC || GET_CODE (x) == POST_INC)
+{
+ xfoo0 = XEXP (x, 0);
+ if (BASE_REGISTER_P (xfoo0, strict))
+ return true;
+}
return false;
}

I'll send another email once I have something substantial to contribute. I give
my permission to NetBSD and the FSF to integrate any or all of my
believe, libm or libc or the kernel or something like that. I do have a test
case for C++ exceptions on VAX, which I will send separately.
Thanks,

Unfortunately, my previous patch that included a change to gcc/config/vax/vax.h
that increased FIRST_PSEUDO_REGISTER from 16 to 17 breaks the C++ exception
handling that I’d worked so hard to get right with the rest of the patch. I
believe I need to define DWARF_FRAME_REGISTERS to 16 in the
As an added bonus, I see that my patch set also included an old m68k patch that
had been sitting in my tree, which fixes a crash when -m68040 is defined. I may
have submitted it to port-m68k before. It hasn’t been tested with the new
compiler either. Here’s that patch separately. It only matter

Hi all,
For several years I’ve been eager to find the time to fix the bugs in C++
exceptions on VAX to get them working on NetBSD, because they’ve been broken
for many years and it looked like only a few changes were needed to get them
working. Without C++ exceptions, the NetBSD test suite
