[PATCH] D102766: [SelectionDAG] Implement PromoteIntRes_INSERT_SUBVECTOR

[Eli Friedman via Phabricator via llvm-commits]

Sorry about the late reply here, but I'm not sure why PromoteIntRes_INSERT_SUBVECTOR needs to go through the stack.  Can't you just ANY_EXTEND the operand and the result?

At that point, you might end up with a node that needs to be legalized by PromoteIntOp_INSERT_SUBVECTOR, but better to take legalization one step at a time.
