[llvm-dev] GlobalsAA from GVN

[Vaivaswatha Nagaraj via llvm-dev]

Hi,

I've noticed that alias analysis queries arising from GVN do not use the
results from GlobalsAA.
The last call to AAResultsWrapperPass::runOnFunction() before GVN does not
add GlobalsAAWrapperPass due to unavailability. This leads to the alias
queries from GVN not having any globals mod-ref info.

Is this a known issue? and is there any way to have globals mod-ref info
available for GVN?

Thanks,

  - Vaivaswatha
