Bug ID: 33051
Summary: NewGVN exhibits non-deterministic behaviour
OS: Windows NT
Component: Scalar Optimizations
Assignee: unassignedbugs at nondot.org
Reporter: davide at freebsd.org

This seems to be a tricky one.
The way to reproduce (thanks Takumi) is that of re-enabling pr32934.ll (in
test/Transform/NewGVN), copying it 1000 times
for x in `seq 1000 1999`;do ln -sv pr32934.ll pr32934_$x.ll;done
and running `ninja check-llvm`.
A bunch of the copies will fail.
I think I narrowed down the problem a bit.
