Node deletion during DAG Combination ?
...;replacing a set of DAG nodes by an (usually smaller) set of DAG nodes, removing dead nodes and updating all the chains'.
I'm using the setTargetDAGCombine(ISD::EXTRACT_VECTOR_ELT) and build the new LOAD_VECTOR_EXTRACT node in the PerformDAGCombine().
As per the following trace this work, t59 and params from t58 are merged into t72.
During this combination, the chain from t59 to t58 has been merged from new t72 to t57, skipping over t58.
So far, so good.
My problem is that this node t58 is not removed from DAG. One reason could be that node t62 is still chained to t58 (due to the fact...
