GVN pass: does global value numbering remove duplicate computations in loops?
> The GVN on the newgvn branch i have will remove these, and is more
complicated
> The one i have implemented unifies AWZ and hash based and will also do
predication/value inference.
This is exciting news. It sounds like it will find a lot of the interesting
cases.
> Note that we don't do full-on polynomial time equivalence finding. While
it would be fun to play with such

[RFC] NewGVN
Hi,
we would like to propose a new Global Value Numbering pass in LLVM.
The ideas/code are from Daniel Berlin (with a minor overhaul/splitting
into submittable patches from me). The code has been around for a
while (2012 or before), and we think it's getting ready to be
committed upstream.
### Motivation
To put things into context: my personal motivation for having a new
GVN/PRE algorithm
