llvm dev - May 2020 - Attempt to use DomTreeBase on a CallGraph or CallGraphNode

Hi,

 

Has anyone successfully been able to implement domination over a callgraph,
I'm getting stuck on supporting DomTreeBuilder for Calculate.

 

Many thanks

Alina - this sounds vaguely like some of the stuff you're working on?

I may need more context here.

If you're trying to use Calculate to compute a new DT with some updates
(i.e. pretend the CFG graph is different), that Calculate method is broken.
It will discard the updates and return a new DT.
Yes, I'm working to fix that.

If it's something else, please give me more details so I can understand
what you're trying to do.

Best,
Alina
