[RFC] Making GVN able to visit the same block more than once
...;t handle it and give
up.
The approach I tried here is:
* Turn Visited into a set of <BasicBlock*,Value*> pairs and keep the behaviour
of ignoring blocks that we've already visited for a value but allow visiting
a block more than once if it's for different values.
* Adjust NonLocalDepResult to mark a result as originating in the block we
started looking in (after phi-translation), not the one we eventually found
it in.
With this GVN then goes on to optimise this function exactly as we want. However
we then get problems elsewhere.
The problem

Let's take a loo...
