FYI, I posted the fix I attached as
http://lists.freedesktop.org/archives/mesa-dev/2014-September/067343.html and a
few other patches that cleanup things I noticed when fixing this, but I don't
have commit

Your patch does indeed fix the crashing tests, I still see some piglit
regressions but that should be either bug 82882 or bug 82978.
Thanks for the fix.

Does this patch fix the piglit failures? For doing a full piglit run, I'd
recommend comparing the

Can you try the patch I attached and tell me what output you get between the

Ok, so indeed I got NO_REG for g->nodes[n2].reg
print g->nodes[n2].reg
$1 = 4294967295
than I set breakpoint at end of ra_simplify (it gets called just once before
the crash)
Breakpoint 1, ra_simplify

--- Comment #7 from Connor Abbott ---
Oh, and I forgot to mention:
If you do find that g->nodes[n2].reg is NO_REG, the next step would be to break
at the end of ra_simplify() (but make sure to stop at the last time the
breakpoint gets hit

All the crashes are in the same place, right?
Can you run it under gdb and print out n2 and the contents of
g->nodes[n].adjacency_list (it's an array with g->nodes[n].adjacency_count
elements) after the

I confirm the same bug on ATI X600 Mobile with Mesa 10.3.0 RC1 .
Flightgear at least triggers it.
