[LLVMdev] State of SCCVN pass
What is the state of SCCVN pass? It looks like no work is done on it after the
initial release. Are there any plans to merge GVN functionality and/or replace
GVN pass in the future?

[LLVMdev] Speculative phi elimination at the top of a loop?
...virtual method, but since the instance object is a *constant* on the first round of the loop, it is possible to resolve the method call into a static function, and then inline the static function, which in this case essentially eliminates the first round of the loop.
The combination of GVN-PRE and SCCVN in GCC will do this, and we
actually block it from doing this in a lot of cases.
Basically, it can discover some value is constant on the first run
through a loop, and will create additional phi nodes to represent
those values.
In most cases, this is not that valuable (IE it would discover i = i...

[LLVMdev] Speculative phi elimination at the top of a loop?
I am working on heavily optimising unusually static C++ code, and have encountered a situation where I basically want an optimiser that would speculatively unroll a loop to see if the first round of the loop could be optimised further. (I happen to know that it is possible.) The previous optimisations that produce the loop in the first place already do a magical job (relying heavily on constant
