[LLVMdev] Are these projects still "open"?

[Prashanth Radhakrishnan]

Hi,

I'm looking to do a semester-long course project involving LLVM.

To avoid duplicating efforts, I wanted to know if the following projects 
(lifted off http://llvm.org/OpenProjects.html) are done with or are 
currently worked upon. Atleast I couldn't find evidence of these in the 
1.9 sources.

   1. Implement GVN-PRE, a powerful and simple Partial Redundancy 
      Elimination algorithm for SSA form
   2. Implement a Dependence Analysis Infrastructure
      - Design some way to represent and query dep analysis
   3. Value range propagation pass

>From what I've seen of LLVM, I think this is a cool Compiler 
Infrastructure you've built!

Thanks,
Prashanth
