llvm dev - Mar 2015 - [LLVMdev] Function of CorrelatedValuePropagation pass

Hi,

I am working on some changes to LazyValueInfo and I wanted to see how it was
used in existing passes.
Currently I can see that Jump Threading and Correlated Value Propagation are the
2 passes that use LazyValueInfo.

However on the LLVM docs page of passes (http://llvm.org/docs/Passes.html
<http://llvm.org/docs/Passes.html>), Correlated Value Propagation is not
mentioned as a pass.
Does this mean that the pass is deprecated or just a mistake ?

Thanks

That web page is out of date. If you want to see what passes are actively in
use, I recommend looking at how the default optimization pipeline is setup
(PassManagerBuilder::populateModulePassManager in
lib/Transforms/IPO/PassManagerBuilder.cpp).

Right. The option for opt would be -correlated-propagation and its
implementation is in lib/Transform/Scalar.
