[LLVMdev] Question about Value Range Propagation

[Gratian Lup]

Hi!
I'm a student who would like to participate on Google SOC for LLVM, and was
thinking about what project to pick. I saw on the "Open projects" page that
Value Range Propagation is not implemented and thought about doing it, based
on a paper by Patterson (it's also used by GCC). But then I saw that last
year someone did a Range Analysis pass that seems to do pretty much the same
thing, but using a different algorithm.
Am I missing something? It's possible that these do something different/have
different usage scenarios?.
If they are the same, I think it would be better to remove it from the open
project list, so other people don't start thinking about how to do it, only
to see later that it's already done :)
