[LLVMdev] Ordering not assigned to DAG Nodes create after DAG builder
Hi Xiaoyi,
Do you still see this behavior after r177525? I recently fixed several
places where ordering was not propagated, including during legalization.
There are probably still cases that are missed, but I'd be interested in
seeing a missed case. I'm guessing it's a legalization that expands to
multiple new nodes. The AssignOrdering ca...

[LLVMdev] Ordering not assigned to DAG Nodes create after DAG builder
Hi,
It seems orderings are not assigned to DAG nodes created after the DAG builder, e.g., DAG nodes created during legalization. This causes instructions being scheduled in different order than source order for O0.
This is my plan to fix it:
Make a utility routine that recursively assign ordering to a chain of nodes, just like what SelectionDAGBuilder::AssignOrderingToNode() does.
Then add call
