[llvm-dev] Access the Post Dominator tree

[Kaarthik Alagapan via llvm-dev]

I’m trying to access the (post) dominator tree at the SelectionDAG phase to get the immediate post dominator block of a branch block. Would the post dominator tree be built at before that stage or does it occur after building the DAG? If it is, how can I get the post dominator tree of the specific block? I’m not able to find a specific function that returns the tree other than getNode but that works on a dominator tree.

Regards,
Kaarthik A.
