Hi,

In following link:
https://www.youtube.com/watch?reload=9&v=6X12D46sRFw

They have specified that the inliner can't use DomTree/LoopInfo/MemorySSA
analysis.
1. What's the reason for this?
2. Why can't we do it using getAnalysisUsage() construct?
3. Can inline use this information in the new Pass Manager?
4. What all information can we derive from DomTree to be of help to inliner?

Regards
Sushant
