[PATCH] D89149: [SelectionDAG] Fix alias checking with potential later stack reuse

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song added a comment.

> As an alternative, we could update ImproveChain (and visitLIFETIME_END) to limit the aliasing 
> around lifetime_start / end to disallow improving the chain dependence of a mem op node
>  from a different lifetime node that may alias. That should prohibit access from two aliasable 
> frame indices from being concurrent while still allowing us to leverage that disjoint allocs should be disjoint.

@niravd Any update on this?
